The egg-drop activity is designed to help students develop a deeper understanding of the force created by wind resistance and how it interacts with the force due to Gravity. Students will note how surface area affects the resistance of a falling object as Gravity works on it. Students will record and share observations and questions regarding the experiment.

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 formation of images by plane and spherical mirrors will be studied by examining paintings done by several masters which include images formed in mirrors.

This activity is an extension where students freeze a liquid, making ice cream.

Spreadsheets Across the Curriculum module. Students examine the number of large earthquakes (magnitude 7 and above) per year for 1970-1999 and 1940-1999. QL: descriptors of a frequency distribution.

This activity is a classroom and field activity in which students record observations of birds in their natural habitat and make connections between the structure and function of the bird feet.

Knowing the fund structure for state and local governments is a key concept students must master early in their study of governmental accounting. In addition, students must be able to identify which fund would be used to account for various activities in which a government engages. This PowerPoint game is a drill and practice/review activity fashioned after the popular TV game show, Hollywood Squares. The celebrities in the Fund Identification Challenge are past Presidents of the United States. The Presidents have responded to a question, and the game participants either agree or disagree with the response to earn the square. The 27 real-world examples found in the game were derived by examining the Comprehensive Annual Financial Reports (CAFR) of various cities.

Students will write and present a paper which consists of a review of literature and an empirical/statistical test of the relation between specific variables in the field of social stratification.

This consists of a short essay to be written by students after watching the West Wing episode "Hartsfield's Landing." In it, students are asked to help a friend to understand the content of the show using the basic components of non-cooperative game theory and the prisoner's dilemma.

This is a field activity where students explore different types of gardens comparing how they are the same and different.

This problem challenges students to design experiments using techniques measuring gene expression (reverse transcriptase PCR, microarrays, in situ hybridization).

Teaching general equilibrium analysis to students is challenging. General equilibrium models are typically accessible to only a small handful of mathematically well prepared students. Yet the growing significance of general equilibrium models in economics challenges instructors to find ways to make these models accessible to undergraduate students. The simulation gives microeconomics instructors an alternative to the traditional Edgeworth box graphical presentation. The simulation, with sample parameter files, is implemented with a Java applet available at General Equilibrium Simulations. The developers of the simulation are Walter Nicholson and Frank Westhoff at Amherst College.

In this lab activity students isolate genomic DNA from their cheek cells on the inside of their mouths. Students then remove the DNA from those cheek cells. It shows the DNA is in every cell in the body and can be extracted easily. Students use their DNA necklace which they proudly wear around school the rest of the day.

This activity is a field investigation where students gather geological information of a designated area and identify the geological features they documented.

This geologic investigation will have students observing and investigating coastal features of Western Lake Superior using inquiry-based investigable questions, and inferring possibilities of the coastal features' origins.

This activity is an inquiry-based field investigation of the geologic history of the Minnehaha Falls and St. Anthony Falls areas of Minneapolis. Students will be introduced to rocks and the stories rocks tell in a genuine geologic context, rather than as samples in the classroom.

This activity is a field investigation where students gather data on fossiliferous limestone, develop an experimental question, and develop a mental model of local geologic history.

This activity is a field investigation of the geological features of Minnehaha Falls, how they have changed and why, how they are changing and what could be done to preserve the falls.

Short Description: This is an inquiry based field investigation where students gather data on the Credit River from the rocks in the river bed, water speed, and maps. Students interpret their findings and develop new questions.
