In this activity, students will mix paints and create a formula to match a muted color. The formula will be tested. Students will discuss their observations and develop new questions about color mixing to pursue.

A case based upon the environmental devastation of the Aral Sea that illustrates economic concepts of opportunity cost and social marginal cost.

Through this independent research project, students experience the process of doing real economics research using appropriate econometric methods.

This activity requires students to research, design, construct, and test a solar oven. Students will collect data from their own individual oven to combine with research of "real-life" solar ovens in an activity ending scientific paper.

This is an Interactive Lecture Demonstration for resolving force vectors using the suspended block demonstration (1J30.10).

The PhET Activities Database is a collection of resources for using PhET sims. It includes hundreds of lesson plans, homework assignments, labs, clicker questions, and more. Some activities have been created by the PhET team and some have been created by teachers.

The purpose, components, and functions of the respiratory system are presented in this learning through disussion and visualizations. Participants learn about the nasal cavity, pharynx, larynx, trachea, bronchi, bronchioles, and alveoli.

In this exercise, students use gestures to re-create the motion of fault blocks adjacent to restraining bends and releasing bends. They then answer a few questions about a map view of the San Andreas Fault and two of its bends.

By examining the progress of a genetic eye disease, students learn about eyes, genetic disorders, and neurons in this case designed for clickers and large lecture sections.

Published in 1986, this Kennedy School case tells the story of Harley-Davidson's application to the ITC for temporary relief from high levels of imported Japanese motorcycles. The case lays out, in considerable detail, Harley's justification for protection and the Japanese manufacturers' counterarguments. The case is presented in two parts, the first focusing on the extent of the "injury" an the second on the nature of the relief Harley requested.

Ricardian Explorer, implemented on the internet, simulates a Ricardian trade model with linear production technology and a CES utility function. The typical simulation has two countries and two goods. While Ricardian explorer was developed to supplement a course in international trade, it can also be used in intermediate microeconomics and microeconomic principles courses. The authors of the simulation are Alberto Isgut and Tanya Rosenblat of Wesleyan University.

After covering the standard course material on area under a curve, Riemann sums and numerical integration, Calculus I students are given a write-pair-share activity that directs them to predict the best area approximation methods for each of several different functions. Afterwards, the instructor employs a Web-based applet that visually displays each method and provides the corresponding numerical approximations.

This activity is a field investigation where students gather data, draw detailed diagrams, and write descriptions about living organisms and non-living things seen in a small school ground area.

This activity takes students through the historical and geological events that shaped the areas near the Minnesota and Mississippi river confluence.

This activity is a field investigation where students observe and develop ideas about rock outcrops and rock characteristics.

The students will participate in listening and discussing the story, Under One Rock: Bugs, Slugs, and Other Ughs, by Anthony D. Fredericks and illustrated by Jennifer DiRubbio. On the following day, we will explore our nearby forest searching for some of the animals mentioned in the story. For the third day of this lesson, the students will share what they have written and drawn in their nature journals from the previous day's walk.

This lab helps students link concepts about how rocks form with observations about how rocks look. It is designed to help them learn rock classification in a more connected manner than is usual.
