This document is a Docoumented Problem Solving exercise that utilizes the Keynesian model of the macroeconomy.

Gross domestic product (GDP) was introduced in class as a way to determine the value of a country's output. Consumption, investment, government spending, and net exports were discussed as the components of GDP. Items that are excluded from GDP were also discussed.

Following a lecture about unemployment, students are asked to calculate the unemployment rate. They will need to apply their knowledge about unemployment and the labor force in order to make the calculation.

Determining a Tax Structure - The different tax structures are reinforced through the calculation of the tax rate at two different income levels.

In this assignment, students think about four events that would affect a country's exchange rate. Without actually drawing a supply and demand diagram, students say what direction, if at all, each curve would shift��and whether the currency would appreciate or depreciate as a result.

The topic of gross domestic product (GDP) was introduced in class. The components of GDP - consumption, investment, government spending, and net exports - were discussed. The items that are excluded from GDP and the difference between GDP and gross national product (GNP) were also explained.

Students in an economics course are asked to write a doumented problem solution to explain how a change in a determinant of demand will impact the equilibrium price.

The concept of comparative advantage is used to make a decision about specialization and trade. The microeconomic impact is also included.

The concept of price elasticity of demand was introduced in class. Elastic and inelastic goods were discussed. The impact that a change in price will have on total revenue was also presented.

During the lecture, labor demand and labor supply were discussed and were used to determine the equilibrium wage rate. Then, the concept of a minimum wage rate was introduced and the impact of the wage rate on the labor market was demonstrated graphically.

During the lecture, the competitive market was introduced. A graph was used to demonstrate a competitive market in which there was an economic profit. The profit motive causes an increase in supply. As additional producers enter the market, the price of the product or service decreases. In the end, price will decrease until the long-run equilibrium situation is reached which means that the economic profit decreases to zero.

This lab introduces basic chemistry concepts in molecular interactions, measurements, prediction, and critical thinking.

This is an inquiry-based activity in which students will need to work together as a class to solve the following problem: they must construct a "boat" entirely out of modeling clay that is capable of supporting 150 grams of cargo without sinking.

Spreadsheets Across the Curriculum module. Students build a spreadsheet to explore the trade-offs between "bargain-priced" gas vs. the extra mileage needed to get it. A modeling problem.

This activity is a bioassay lab where students tested the effect of an environmental toxin (fertilizer) on the growth rate of Duckweed.

Spreadsheets Across the Curriculum module/Geology of National Parks course. Students estimate the volume of sand in Hoosier Slide, a large dome-shaped dune quarried away in the 1920s from what is now Indiana Dunes National Lakeshore. They also estimate the number of boxcars to carry the sand, and the number of Ball jars produced from it.

The Dynamic Integrated Climate Change (DICE) model assumes a single world producer must chose levels for three simultaneously determined variables: current consumption, investment, and greenhouse gases reduction. The model is freely available in both a GAMS and Excel version. DICE allows both science and economics instructors to integrate a sophisticated economic model of climate change into their courses. The simulation is for upper-division courses where students have some background in microeconomics. The principle developer is William Nordhaus at Yale University.

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.
