In this jigsaw, students will graph various Bald Eagle population numbers and determine the impact humans have had on the eagle. Specifically, they will investigate why the Bald Eagle was listed as endangered, the affects of DDT on eagles, and the affects of lead. Based on an original activity titled "Bald Eagle Population Graphing" from The Raptor Center, University of Minnesota http://www.cvm.umn.edu/raptor/prod/groups/cvm/@pub/@cvm/documents/asset/cvm_66866.pdf

This is a classroom activity in which students develop understanding of the rock cycle using wax crayons to model the processes that form the 3 types of rock; sedimentary, igneous & metamorphic.

This activity poses the question: What would happen if a meteor or comet impacted Earth? Students simulate an impact in a container of sand using various-sized rocks, all while measuring, recording and graphing results and conclusions. Then students brainstorm ways to prevent an object from hitting the Earth.

This is an indoor and outdoor activity where students understand the distance the earth is from the sun. The students understand that the earth rotates on it's axis once in a 24 hour period thus providing us with day and night.

This lesson introduces and describes the main types of erosion (i.e., chemical, water, wind, glacier and temperature). Students learn examples of each type of erosion and discuss how erosion changes the surface of the Earth. Students also learn why engineers need to be aware of the different types of erosion in order to protect structures and landmarks from the damaging effects erosion can cause. Figure 1 is an excellent illustration of water erosion.

Spreadsheets Across the Curriculum module. Students build spreadsheets to tabulate and graph seismic wave amplitude and energy release to explore the logarithmic scale of earthquake magnitude.

Students learn how engineers construct buildings to withstand damage from earthquakes by building their own structures with toothpicks and marshmallows. Students test how earthquake-proof their buildings are by testing them on an earthquake simulated in a pan of Jell-O(TM).

This list of carefully selected books for grades K-5 highlights nonfiction about climate proxies, those preserved physical characteristics, such as fossils, that scientists use to reconstruct past climates. Also highlighted are a few books that provide information about two past climatic events -- the last ice age and the Dust Bowl. In each issue of the free, online magazine Beyond Weather and the Water Cycle, the virtual bookshelf recommends books that accurately portray the theme drawn from the principles of climate sciences.

Spreadsheets Across the Curriculum module. Students build spreadsheets to forward calculate the Earth's aggregate density from combinations of densities and thicknesses of the Earth's four shells.

In this 7- lesson unit students use tallies, pictographs, bar graphs, line plots, circle graphs, box-and-whisker plots, and glyphs to collect and display data about healthy eating. The unit includes lessons in which two sets of data are being compared and data sets are being analyzed for measures of central tendency (mean, median, mode). Learning objectives, materials, student questions, extensions, teacher reflections, and links to create graphs virtually are included.

In this activity, students will experience echolocation themselves. They actually try echolocation by wearing blindfolds while another student makes snapping noises in front of, behind, or to the side of them.

The activity is designed to be an interative lecture segment during a larger interactive lecture class period. The technique demonstrated through this example is a double entry journal.

The course discusses the economic aspects of current issues in education, using both economic theory and econometric and institutional readings.

Working in groups of three, students analyze economies of scale. Each student constructs an individual short-run ATC curve, then the three students collaborate to determine if there are economies or diseconomies of scale and to create the long run ATC.

Students will explore and create a healthy ecosystem, once established they will then introduce additional variables which may harm the ecosystem and determine which hazards should be avoided.
