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 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.

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.

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.

This field investigation allows students to collect and observe earthworms using liquid extraction to help develop background knowledge at the start of a new earthworm unit.

Ebay is a parody of I Want it That Way by the Backstreet Boys a #1 hit from 1999. This song contains animated lyrics and an economic explanation that are synchronized to the music. The song explores a wide range of economic issues including: markets, supply and demand, and gains from trade.

This short lesson was designed in collaboration with a 7th grade Life Science teacher (Paul Jeffery). The idea behind the lesson is to help students better understand ecological and geographical classifications by teaching them at the same time in their Life Science class and their Geography class. Teaching the two classifications together will help reinforce the idea of classification. While this lesson would best be taught outdoors it can also be adapted to the indoors.

This site contains 21 modular, easy to use economic models, that are appropriate for class assignments or in-class demonstrations. Students can simulate all the standard models taught in most economics courses. EconModel uses the Windows OS. The simulations were developed by William R. Parke of the University of North Carolina at Chapel Hill.

Through a close study of a rich set of demographic and economic statistics, students will see the development over 150 years of two similar yet divergent colonies (Virginia and Barbados). They will work through population, land use, and trade statistics with closely-guiding questions in order to find links between one set of numbers and another.

This activity helps a student recognize the consequences of Type I and Type II errors in hypothesis testing.

The department of economics at Elon changed its curriculum in 1995 to require an independent senior thesis for all majors. Since that time, this activity has evolved tremendously. In 2009, we changed the curriculum again to require a 2 semester hour Fall seminar component to go along with the 2 semester hours. of independent research each student completes in the Spring of their senior year.

In both macroeconomics and microeconomics principles courses, economists teach the virtue of markets as an allocative mechanism. But markets sometimes fail. This example allows students to simulate the market failure associated with a common property resource, a salmon fishery, and evaluate ways to control fishing. The simulation also shows the distributional results of different allocative mechanisms. The simulation was developed by Paul Romer at Stanford University and is available on the Aplia web site.

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.

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.

This activity is an open-ended inquiry investigation in which students analyze and predict how an environmental change will affect the visitation rates of insects. Students will ask a question, develop multiple hypotheses, run a scientific investigation, and report their findings to their "colleagues".

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.

This activity is a field trip investigation where students gather stream flow, volume, depth & height (area) data on Ramsey County dams (Keller and Round lake), interpret their findings and make in-depth observations in order to assess the effectiveness of dams through the season and estimate the life-span of the dams in years.

This activity is an in class lab where students will compare different acid solutions on seed germination and growth.

This classroom activity presents College Algebra students with a ConcepTest, a Question of the Day, and a Write-pair-share activity concerning the effect of the coefficient of x^0 (i.e., the constant, c) on the vertex of a parabola where a and b are arbitrarily fixed values in f(x)=ax^2+bx+c.
