1 BACKGROUND The new generation of enhanced mid core PICs such as the 16F1847 and the 12F1840 have an inbuilt temperature sensor. This sensor consists of a current source which flows through four diodes in series and the voltage drop across the diodes which is proportional to temperature can be measured by internally connecting the sensor to the ADC and determining the temperature based on the ADC value In this assignment the temperature sensor is used to create a simple thermometer application and to create an alarm should the sensor go outside the set value. Assignment Details 1) Determine the register settings needed to switch the sensor on and connect the temperature sensor to the ADC. Using appropriate values for Vref+ and Vref- display the ADC count value on the 7 segment display. 2) With reference to Microchip Application Note AN1333, “Use and Calibration of the Internal Temperature Indicator” (DS01333) determine an appropriate algorithm to convert from the ADC value to the temperature in degrees centigrade and implement it using a lookup table or otherwise. Display this value on the 7 segment display. Additional marks will be given for accuracy, calibration and averaging the temperature readings to give a more accurate, and a more stable temperature reading. . 2 In order to meet the specification the following will be required. i) Selection of appropriate microcontroller to meet the requirement of the task. ii) Development of an assembly language program to control the operation of the embedded system. iii) Thorough testing to ensure correct operation of the system. iv) Produce a project report to evidence all of the above.

The Geographic Grid The Geographic grid is based on angular measurements from the center of the earth. Latitude measures the angular distance north and south of the plane of the earth’s equator. longitude measures the angular distance east and west of the prime meridian. The angular distance between any two locations on the earth’s surface is simply the latitudinal or longitudinal difference the two locations. Both longitude and latitude are measured in degrees ( o ), minutes ( ‘ ) and seconds ( ” ) of arc. Figure 1 shows the latitude and longitude coordinates of the earth in 10o degree intervals. There are 60′ minutes of arc in 1o . There are 60″ seconds of arc in 1′ minute of arc. One could therefore express the latitude and longitude of a place as 39o 50′ 10″ N, 77o 35′ 15″ W. 1. Using latitude and longitude coordinates, determine the location of the following places. a) Toronto, Ontario ( Canada ) ____________________________________________________________ b) Billings, Montana _____________________________________________________________________ c) Chicago, Illinois ______________________________________________________________________ d) Westminster, England _________________________________________________________________ e) Venice, Italy _________________________________________________________________________ f) Baghdad, Iraq _______________________________________________________________________ g) Tokyo, Japan ________________________________________________________________________ h) Rio de Janeiro, Brazil _________________________________________________________________ 2. Provide the name of the following places located at the given coordinates below. a) 13o 09′ 50.19″ S, 72o 32′ 45.58″ W ______________________________________________________ b) 33o 51′ 35.90″ S, 151o 12′ 40″ E ______________________________________________________ c) 71o 17′ 07.62″ N, 156o 45′ 57.98″ W _____________________________________________________ d) 41o 53′ 29.84″ N, 87o 36′ 01.78″ W ______________________________________________________ The geographic grid uses circles of two different types, great circles and small circles. All great circles pass through the geographic center of the earth. All meridians, the equator, and the circle of illumination are great circles. All parallels other than the equator are small circles. The direction of any grid lines ( meridians and parallels ) can be determined as either an azimuth or a bearing. Azimuths are read in a clockwise direction as degrees ranging from 0o at the North Pole, to 90o at East, to 180o at the South Pole, to 270o at West, and back to 360o at the North Pole. Azimuths only give a direction such as 45o . Bearings are read as quadrants from either the North or South Poles. Hence east is 90o from either North or South. West is also 90o from either North or South. A bearing shows the direction one is traveling as well as the magnitude of the angle from either North or South. Hence a azimuth of 45o is read as a bearing of N 45o E. An azimuth of 150o would as a bearing read S 30o E. Figure 1.2 shows the relationship between azimuths and bearings. 3. Convert the values below. Bearing Azimuth 20o S 500 20′ E 265o 30’ N 20o 20 W Longitudinal and latitudinal distances vary as a result of trying to fit a flat grid onto a spherical surface such as the earth’s curved surface. The grid is constant in a north-south direction, but varies in the east-west direction. The data below shows how the grid values vary ( rounded off to the nearest mile of distance ). 1o of longitude at the equator = 69 miles 1o of longitude at the 30th parallel = 60 miles 1o of longitude at the 60th parallel = 35 miles 1o of longitude at the 90th parallel = 0 miles 1o of latitude along any meridian = 69 miles 4. Determine by calculation the linear ( miles ) and angular ( degree ) distances between the following places. From To Angular Linear Quito, Ecuador Macapa, Brazil 0o S, 78o W 0o N, 51o W Cairo, Egypt Shiraz, Iran 30o N, 31o E 30o N, 52o E Seward, Alaska St Petersburg, Russia 60o N, 149o W 60o N, 30o E Hamhung, North Korea Ankara, Turkey 39o N, 127o E 39o N, 32o E Detroit, Michigan Morristown, Tennessee 42o N, 83o W 36o N, 83o W Sample problem We see that between Quito and Macapa that there is no latitude difference as both places are at 0 degrees latitude. Therefore the angular difference between the two places can only be calculated based upon the longitudinal difference. Seeing that both places are west longitude we simply subtract 78-51 = 27 degrees. Hence the angular distance between Quito and Macapa is 27 degrees. The linear distance is the number of miles ( feet,yards, kilometers, etc.) Quito and Macapa. Bothe places are on the equator so consulting the table above we find that in 1 degree of longitude ate the equator is equal to 69 miles. So multiplying the 69 miles/degree X 27 degrees, the degrees cancel and the remaining units are miles, and the numerical value is 1,863 linear miles.

Read this article and answer this question in 2 pages : Answers should be from the below article only. What is the difference between “standards-based” and “standards-embedded” curriculum? what are the curricular implications of this difference? Article: In 2007, at the dawn of 21st century in education, it is impossible to talk about teaching, curriculum, schools, or education without discussing standards . standards-based v. standards-embedded curriculum We are in an age of accountability where our success as educators is determined by individual and group mastery of specific standards dem- onstrated by standardized test per- formance. Even before No Child Left Behind (NCLB), standards and measures were used to determine if schools and students were success- ful (McClure, 2005). But, NCLB has increased the pace, intensity, and high stakes of this trend. Gifted and talented students and their teach- ers are significantly impacted by these local or state proficiency stan- dards and grade-level assessments (VanTassel-Baska & Stambaugh, 2006). This article explores how to use these standards in the develop- ment of high-quality curriculum for gifted students. NCLB, High-Stakes State Testing, and Standards- Based Instruction There are a few potentially positive outcomes of this evolution to public accountability. All stakeholders have had to ask themselves, “Are students learning? If so, what are they learning and how do we know?” In cases where we have been allowed to thoughtfully evaluate curriculum and instruction, we have also asked, “What’s worth learning?” “When’s the best time to learn it?” and “Who needs to learn it?” Even though state achievement tests are only a single measure, citizens are now offered a yardstick, albeit a nar- row one, for comparing communities, schools, and in some cases, teachers. Some testing reports allow teachers to identify for parents what their chil- dren can do and what they can not do. Testing also has focused attention on the not-so-new observations that pov- erty, discrimination and prejudices, and language proficiency impacts learning. With enough ceiling (e.g., above-grade-level assessments), even gifted students’ actual achievement and readiness levels can be identi- fied and provide a starting point for appropriately differentiated instruc- tion (Tomlinson, 2001). Unfortunately, as a veteran teacher for more than three decades and as a teacher-educator, my recent observa- tions of and conversations with class- room and gifted teachers have usually revealed negative outcomes. For gifted children, their actual achievement level is often unrecognized by teachers because both the tests and the reporting of the results rarely reach above the student’s grade-level placement. Assessments also focus on a huge number of state stan- dards for a given school year that cre- ate “overload” (Tomlinson & McTighe, 2006) and have a devastating impact on the development and implementation of rich and relevant curriculum and instruction. In too many scenarios, I see teachers teach- ing directly to the test. And, in the worst cases, some teachers actually teach The Test. In those cases, The Test itself becomes the curriculum. Consistently I hear, “Oh, I used to teach a great unit on ________ but I can’t do it any- more because I have to teach the standards.” Or, “I have to teach my favorite units in April and May after testing.” If the outcomes can’t be boiled down to simple “I can . . .” state- ments that can be posted on a school’s walls, then teachers seem to omit poten- tially meaningful learning opportunities from the school year. In many cases, real education and learning are being trivial- ized. We seem to have lost sight of the more significant purpose of teaching and learning: individual growth and develop- ment. We also have surrendered much of the joy of learning, as the incidentals, the tangents, the “bird walks” are cut short or elimi- nated because teachers hear the con- stant ticking clock of the countdown to the state test and feel the pressure of the way-too-many standards that have to be covered in a mere 180 school days. The accountability movement has pushed us away from seeing the whole child: “Students are not machines, as the standards movement suggests; they are volatile, complicated, and paradoxical” (Cookson, 2001, p. 42). How does this impact gifted chil- dren? In many heterogeneous class- rooms, teachers have retreated to traditional subject delineations and traditional instruction in an effort to ensure direct standards-based instruc- tion even though “no solid basis exists in the research literature for the ways we currently develop, place, and align educational standards in school cur- ricula” (Zenger & Zenger, 2002, p. 212). Grade-level standards are often particularly inappropriate for the gifted and talented whose pace of learning, achievement levels, and depth of knowledge are significantly beyond their chronological peers. A broad-based, thematically rich, and challenging curriculum is the heart of education for the gifted. Virgil Ward, one of the earliest voices for a differen- tial education for the gifted, said, “It is insufficient to consider the curriculum for the gifted in terms of traditional subjects and instructional processes” (Ward, 1980, p. 5). VanTassel-Baska Standards-Based v. Standards-Embedded Curriculum gifted child today 45 Standards-Based v. Standards-Embedded Curriculum and Stambaugh (2006) described three dimensions of successful curriculum for gifted students: content mastery, pro- cess and product, and epistemological concept, “understanding and appre- ciating systems of knowledge rather than individual elements of those systems” (p. 9). Overemphasis on testing and grade-level standards limits all three and therefore limits learning for gifted students. Hirsch (2001) concluded that “broad gen- eral knowledge is the best entrée to deep knowledge” (p. 23) and that it is highly correlated with general ability to learn. He continued, “the best way to learn a subject is to learn its gen- eral principles and to study an ample number of diverse examples that illustrate those principles” (Hirsch, 2001, p. 23). Principle-based learn- ing applies to both gifted and general education children. In order to meet the needs of gifted and general education students, cur- riculum should be differentiated in ways that are relevant and engaging. Curriculum content, processes, and products should provide challenge, depth, and complexity, offering multiple opportunities for problem solving, creativity, and exploration. In specific content areas, the cur- riculum should reflect the elegance and sophistication unique to the discipline. Even with this expanded view of curriculum in mind, we still must find ways to address the current reality of state standards and assess- ments. Standards-Embedded Curriculum How can educators address this chal- lenge? As in most things, a change of perspective can be helpful. Standards- based curriculum as described above should be replaced with standards- embedded curriculum. Standards- embedded curriculum begins with broad questions and topics, either discipline specific or interdisciplinary. Once teachers have given thoughtful consideration to relevant, engaging, and important content and the con- nections that support meaning-making (Jensen, 1998), they next select stan- dards that are relevant to this content and to summative assessments. This process is supported by the backward planning advocated in Understanding by Design by Wiggins and McTighe (2005) and its predecessors, as well as current thinkers in other fields, such as Covey (Tomlinson & McTighe, 2006). It is a critical component of differenti- ating instruction for advanced learners (Tomlinson, 2001) and a significant factor in the Core Parallel in the Parallel Curriculum Model (Tomlinson et al., 2002). Teachers choose from standards in multiple disciplines at both above and below grade level depending on the needs of the students and the classroom or program structure. Preassessment data and the results of prior instruc- tion also inform this process of embed- ding appropriate standards. For gifted students, this formative assessment will result in “more advanced curricula available at younger ages, ensuring that all levels of the standards are traversed in the process” (VanTassel-Baska & Little, 2003, p. 3). Once the essential questions, key content, and relevant standards are selected and sequenced, they are embedded into a coherent unit design and instructional decisions (grouping, pacing, instructional methodology) can be made. For gifted students, this includes the identification of appropri- ate resources, often including advanced texts, mentors, and independent research, as appropriate to the child’s developmental level and interest. Applying Standards- Embedded Curriculum What does this look like in practice? In reading the possible class- room applications below, consider these three Ohio Academic Content Standards for third grade: 1. Math: “Read thermometers in both Fahrenheit and Celsius scales” (“Academic Content Standards: K–12 Mathematics,” n.d., p. 71). 2. Social Studies: “Compare some of the cultural practices and products of various groups of people who have lived in the local community including artistic expression, religion, language, and food. Compare the cultural practices and products of the local community with those of other communities in Ohio, the United States, and countries of the world” (Academic Content Standards: K–12 Social Studies, n.d., p. 122). 3. Life Science: “Observe and explore how fossils provide evidence about animals that lived long ago and the nature of the environment at that time” (Academic Content Standards: K–12 Science, n.d., p. 57). When students are fortunate to have a teacher who is dedicated to helping all of them make good use of their time, the gifted may have a preassessment opportunity where they can demonstrate their familiarity with the content and potential mastery of a standard at their grade level. Students who pass may get to read by them- selves for the brief period while the rest of the class works on the single outcome. Sometimes more experienced teachers will create opportunities for gifted and advanced students Standards-Based v. Standards-Embedded Curriculum to work on a standard in the same domain or strand at the next higher grade level (i.e., accelerate through the standards). For example, a stu- dent might be able to work on a Life Science standard for fourth grade that progresses to other communities such as ecosystems. These above-grade-level standards can provide rich material for differentiation, advanced problem solving, and more in-depth curriculum integration. In another classroom scenario, a teacher may focus on the math stan- dard above, identifying the standard number on his lesson plan. He creates or collects paper thermometers, some showing measurement in Celsius and some in Fahrenheit. He also has some real thermometers. He demonstrates thermometer use with boiling water and with freezing water and reads the different temperatures. Students complete a worksheet that has them read thermometers in Celsius and Fahrenheit. The more advanced students may learn how to convert between the two scales. Students then practice with several questions on the topic that are similar in structure and content to those that have been on past proficiency tests. They are coached in how to answer them so that the stan- dard, instruction, formative assess- ment, and summative assessment are all aligned. Then, each student writes a statement that says, “I can read a thermometer using either Celsius or Fahrenheit scales.” Both of these examples describe a standards-based environment, where the starting point is the standard. Direct instruction to that standard is followed by an observable student behavior that demonstrates specific mastery of that single standard. The standard becomes both the start- ing point and the ending point of the curriculum. Education, rather than opening up a student’s mind, becomes a series of closed links in a chain. Whereas the above lessons may be differentiated to some extent, they have no context; they may relate only to the next standard on the list, such as, “Telling time to the nearest minute and finding elapsed time using a cal- endar or a clock.” How would a “standards-embed- ded” model of curriculum design be different? It would begin with the development of an essential ques- tion such as, “Who or what lived here before me? How were they different from me? How were they the same? How do we know?” These questions might be more relevant to our con- temporary highly mobile students. It would involve place and time. Using this intriguing line of inquiry, students might work on the social studies stan- dard as part of the study of their home- town, their school, or even their house or apartment. Because where people live and what they do is influenced by the weather, students could look into weather patterns of their area and learn how to measure temperature using a Fahrenheit scale so they could see if it is similar now to what it was a century ago. Skipping ahead to consideration of the social studies standard, students could then choose another country, preferably one that uses Celsius, and do the same investigation of fossils, communities, and the like. Students could complete a weather comparison, looking at the temperature in Celsius as people in other parts of the world, such as those in Canada, do. Thus, learning is contextualized and connected, dem- onstrating both depth and complexity. This approach takes a lot more work and time. It is a sophisticated integrated view of curriculum devel- opment and involves in-depth knowl- edge of the content areas, as well as an understanding of the scope and sequence of the standards in each dis- cipline. Teachers who develop vital single-discipline units, as well as inter- disciplinary teaching units, begin with a central topic surrounded by subtopics and connections to other areas. Then they connect important terms, facts, or concepts to the subtopics. Next, the skilled teacher/curriculum devel- oper embeds relevant, multileveled standards and objectives appropriate to a given student or group of stu- dents into the unit. Finally, teachers select the instructional strategies and develop student assessments. These assessments include, but are not lim- ited to, the types of questions asked on standardized and state assessments. Comparing Standards- Based and Standards- Embedded Curriculum Design Following is an articulation of the differences between standards-based and standards-embedded curriculum design. (See Figure 1.) 1. The starting point. Standards- based curriculum begins with the grade-level standard and the underlying assumption that every student needs to master that stan- dard at that moment in time. In standards-embedded curriculum, the multifaceted essential ques- tion and students’ needs are the starting points. 2. Preassessment. In standards- based curriculum and teaching, if a preassessment is provided, it cov- ers a single standard or two. In a standards-embedded curriculum, preassessment includes a broader range of grade-level and advanced standards, as well as students’ knowledge of surrounding content such as background experiences with the subject, relevant skills (such as reading and writing), and continued on page ?? even learning style or interests. gifted child today 47 Standards-Based v. Standards-Embedded Curriculum Standards Based Standards Embedded Starting Points The grade-level standard. Whole class’ general skill level Essential questions and content relevant to individual students and groups. Preassessment Targeted to a single grade-level standard. Short-cycle assessments. Background knowledge. Multiple grade-level standards from multiple areas connected by the theme of the unit. Includes annual learning style and interest inventories. Acceleration/ Enrichment To next grade-level standard in the same strand. To above-grade-level standards, as well as into broader thematically connected content. Language Arts Divided into individual skills. Reading and writing skills often separated from real-world relevant contexts. The language arts are embedded in all units and themes and connected to differentiated processes and products across all content areas. Instruction Lesson planning begins with the standard as the objective. Sequential direct instruction progresses through the standards in each content area separately. Strategies are selected to introduce, practice, and demonstrate mastery of all grade-level standards in all content areas in one school year. Lesson planning begins with essential questions, topics, and significant themes. Integrated instruction is designed around connections among content areas and embeds all relevant standards.

Few classroom teachers have been provided with the in-depth professional develop- ment and understanding of curric- ulum compacting that would allow them to implement this effectively. In standards-embedded curricu- lum, enrichment and extensions of learning are more possible and more interesting because ideas, top- ics, and questions lend themselves more easily to depth and complex- ity than isolated skills. 4. Language arts. In standards- based classrooms, the language arts have been redivided into sepa- rate skills, with reading separated from writing, and writing sepa- rated from grammar. To many concrete thinkers, whole-language approaches seem antithetical to teaching “to the standards.” In a standards-embedded classroom, integrated language arts skills (reading, writing, listening, speak- ing, presenting, and even pho- nics) are embedded into the study of every unit. Especially for the gifted, the communication and language arts are essential, regard- less of domain-specific talents (Ward, 1980) and should be com- ponents of all curriculum because they are the underpinnings of scholarship in all areas. 5. Instruction. A standards-based classroom lends itself to direct instruction and sequential pro- gression from one standard to the next. A standards-embedded class- room requires a variety of more open-ended instructional strate- gies and materials that extend and diversify learning rather than focus it narrowly. Creativity and differ- entiation in instruction and stu- dent performance are supported more effectively in a standards- embedded approach. 6. Assessment. A standards-based classroom uses targeted assess- ments focused on the structure and content of questions on the externally imposed standardized test (i.e., proficiency tests). A stan- dards-embedded classroom lends itself to greater use of authentic assessment and differentiated 3. Acceleration/Enrichment. In a standards-based curriculum, the narrow definition of the learning outcome (a test item) often makes acceleration or curriculum compact- ing the only path for differentiating instruction for gifted, talented, and/ or advanced learners.

Read this article and answer this question in 2 pages : Answers should be from the below article only. What is the difference between “standards-based” and “standards-embedded” curriculum? what are the curricular implications of this difference? Article: In 2007, at the dawn of 21st century in education, it is impossible to talk about teaching, curriculum, schools, or education without discussing standards . standards-based v. standards-embedded curriculum We are in an age of accountability where our success as educators is determined by individual and group mastery of specific standards dem- onstrated by standardized test per- formance. Even before No Child Left Behind (NCLB), standards and measures were used to determine if schools and students were success- ful (McClure, 2005). But, NCLB has increased the pace, intensity, and high stakes of this trend. Gifted and talented students and their teach- ers are significantly impacted by these local or state proficiency stan- dards and grade-level assessments (VanTassel-Baska & Stambaugh, 2006). This article explores how to use these standards in the develop- ment of high-quality curriculum for gifted students. NCLB, High-Stakes State Testing, and Standards- Based Instruction There are a few potentially positive outcomes of this evolution to public accountability. All stakeholders have had to ask themselves, “Are students learning? If so, what are they learning and how do we know?” In cases where we have been allowed to thoughtfully evaluate curriculum and instruction, we have also asked, “What’s worth learning?” “When’s the best time to learn it?” and “Who needs to learn it?” Even though state achievement tests are only a single measure, citizens are now offered a yardstick, albeit a nar- row one, for comparing communities, schools, and in some cases, teachers. Some testing reports allow teachers to identify for parents what their chil- dren can do and what they can not do. Testing also has focused attention on the not-so-new observations that pov- erty, discrimination and prejudices, and language proficiency impacts learning. With enough ceiling (e.g., above-grade-level assessments), even gifted students’ actual achievement and readiness levels can be identi- fied and provide a starting point for appropriately differentiated instruc- tion (Tomlinson, 2001). Unfortunately, as a veteran teacher for more than three decades and as a teacher-educator, my recent observa- tions of and conversations with class- room and gifted teachers have usually revealed negative outcomes. For gifted children, their actual achievement level is often unrecognized by teachers because both the tests and the reporting of the results rarely reach above the student’s grade-level placement. Assessments also focus on a huge number of state stan- dards for a given school year that cre- ate “overload” (Tomlinson & McTighe, 2006) and have a devastating impact on the development and implementation of rich and relevant curriculum and instruction. In too many scenarios, I see teachers teach- ing directly to the test. And, in the worst cases, some teachers actually teach The Test. In those cases, The Test itself becomes the curriculum. Consistently I hear, “Oh, I used to teach a great unit on ________ but I can’t do it any- more because I have to teach the standards.” Or, “I have to teach my favorite units in April and May after testing.” If the outcomes can’t be boiled down to simple “I can . . .” state- ments that can be posted on a school’s walls, then teachers seem to omit poten- tially meaningful learning opportunities from the school year. In many cases, real education and learning are being trivial- ized. We seem to have lost sight of the more significant purpose of teaching and learning: individual growth and develop- ment. We also have surrendered much of the joy of learning, as the incidentals, the tangents, the “bird walks” are cut short or elimi- nated because teachers hear the con- stant ticking clock of the countdown to the state test and feel the pressure of the way-too-many standards that have to be covered in a mere 180 school days. The accountability movement has pushed us away from seeing the whole child: “Students are not machines, as the standards movement suggests; they are volatile, complicated, and paradoxical” (Cookson, 2001, p. 42). How does this impact gifted chil- dren? In many heterogeneous class- rooms, teachers have retreated to traditional subject delineations and traditional instruction in an effort to ensure direct standards-based instruc- tion even though “no solid basis exists in the research literature for the ways we currently develop, place, and align educational standards in school cur- ricula” (Zenger & Zenger, 2002, p. 212). Grade-level standards are often particularly inappropriate for the gifted and talented whose pace of learning, achievement levels, and depth of knowledge are significantly beyond their chronological peers. A broad-based, thematically rich, and challenging curriculum is the heart of education for the gifted. Virgil Ward, one of the earliest voices for a differen- tial education for the gifted, said, “It is insufficient to consider the curriculum for the gifted in terms of traditional subjects and instructional processes” (Ward, 1980, p. 5). VanTassel-Baska Standards-Based v. Standards-Embedded Curriculum gifted child today 45 Standards-Based v. Standards-Embedded Curriculum and Stambaugh (2006) described three dimensions of successful curriculum for gifted students: content mastery, pro- cess and product, and epistemological concept, “understanding and appre- ciating systems of knowledge rather than individual elements of those systems” (p. 9). Overemphasis on testing and grade-level standards limits all three and therefore limits learning for gifted students. Hirsch (2001) concluded that “broad gen- eral knowledge is the best entrée to deep knowledge” (p. 23) and that it is highly correlated with general ability to learn. He continued, “the best way to learn a subject is to learn its gen- eral principles and to study an ample number of diverse examples that illustrate those principles” (Hirsch, 2001, p. 23). Principle-based learn- ing applies to both gifted and general education children. In order to meet the needs of gifted and general education students, cur- riculum should be differentiated in ways that are relevant and engaging. Curriculum content, processes, and products should provide challenge, depth, and complexity, offering multiple opportunities for problem solving, creativity, and exploration. In specific content areas, the cur- riculum should reflect the elegance and sophistication unique to the discipline. Even with this expanded view of curriculum in mind, we still must find ways to address the current reality of state standards and assess- ments. Standards-Embedded Curriculum How can educators address this chal- lenge? As in most things, a change of perspective can be helpful. Standards- based curriculum as described above should be replaced with standards- embedded curriculum. Standards- embedded curriculum begins with broad questions and topics, either discipline specific or interdisciplinary.

This leaves only 2.78% of all of Earth’s water as fresh water (non-oceanic). Part C Which of the following is true of the hydrologic cycle? ANSWER: Correct About 20% of the moisture evaporated from the ocean combines with 2% of land-derived moisture to produce 22% of all precipitation that falls over land. Clearly, the bulk of continental precipitation comes from the oceanic portion of the cycle. Concept Review: Eutrophication Can you sequence the steps in the eutrophication process that occurs in a body of water? Part A Drag each statement to the appropriate location in the flowchart of the eutrophication process. ANSWER: soil. ice sheets and glaciers. the rivers and lakes of the world. groundwater resources. about the same amount of water as all groundwater sources combined. most of the fresh water on Earth. the bulk of all of the water found on Earth. about the same amount of water as all Earth’s rivers and lakes combined. Atmospheric water and surface water do not mix. Most evaporation on Earth occurs over the continents. The bulk of the precipitation occurs over land. Most of the water that falls on the continents is derived from the oceans.
