A high speed video clip of a roller coaster is used as an example of conservation of mechanical energy. Students use the video to determine whether mechanical energy is conserved while the roller coaster rolls up, and then back down a hil.

Students develop and conduct an experiment using the law of conservation of mass to determine whether or not gum should be considered food. Students will compare the mass swallowed for sugar and sugar-free gum. This could be used to discuss solubility.

This active demonstration investigates the law of conservation of momentum using a person on rollerblades and a thrown medicine ball.

An interactive lecture in which students use data on feeding habits and habitat, skeletons, and DNA sequences to draw phylogenetic trees.

Successful completion of this cooperative learning activity requires the active involvement of the individual, the small group and the entire classroom (collaboration). The goal is to make a simple task as complicated as possible by constructing a single complex machine.

This online quiz on sustainable development can be used in French language classes to prepare intermediate-level students for discussions on environmental topics. The resource is excellent for immersion and content-based instruction.

Using paper towels this activity introduces using the scientific method to set up and test and experiment.

Context Rich Problem on demand shifters and the implications of such a shift.

In this context rich problem, students are asked to analyze the effects of a price ceiling.

Context-rich problem for electrostatics in an introductory physics class. The instructional setting uses cooperative group problem solving.

Students use gesture to describe the bulk deformation and local deformation apparent in images of a contractional analog experiment. Students then calculate bulk shortening and bulk thickening for the experiment and describe the structures accommodating that strain.

This activity describes the construction and use of a pneumatic cannon and free falling target used to teach the concepts of projectile motion in introductory physics.

This is a cooperative learning exerise that allows students to learn about comparative advantage and the gains from trade.

In this example students examine and critique an argument which implies that it is not cost effective to pay for an automobile with increased fuel efficiency. Using a few reasonable assumptions shows that some of the writer's quantitative claims are not very accurate.

Working in small groups, students determine how 18 items are included in GDP (or if they are excluded.) Cards turned over one at a time encourage participation by all group members.

This assignment engages students in an environmental history class in the use of quantitative data, and raises questions about the nature and meaning of that data, and how it might be utilized.

This activity is a field investigation where students observe plants, animals, and insects that are common to Minnesota.

This activity gives a visual representation of how we are able to see the different layers of metamorphic rocks.

This activity gives a visual representation of how we are able to observe many colors in a sunrise or sunset.
