This activity is a laboratory activity where students gather data relating quantities of salt to the freezing point of water/ice.

This activity is a classroom and lab investigation of magnetism. Students gather results of experiments involving the forces of magnets. They use this data to develop their own experiments to test properties of magnets.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

Using the scientific method this simple hands on experiment is designed to verify Newton's Second Law.

This activity is a field investigation where students gather information before and after learning about plants, which will allow you to compare the knowledge the previously know and have acquired through your teaching.

This activity is a class lab activity in which students will observe unknown rocks and learn about how they fit into the rock cycle.

In this introductory physics lab activity, students explore the sounds made by the free-end of a ruler vibrating off the end of a desk.

A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.

This activity is a field investigation where students make observations of the pebble beach, lava flows, and wetland restoration at Sugarloaf Cove to generate questions to be addressed throughout the earth science curriculum.

This is a two-part activity that implements an extension of the "think-pair-share" cooperative learning technique to study the determinants of supply and demand through hypothetical and real world examples.

This is a teacher demonstration used to show an example of kinetic molecular energy using food coloring and water. The students are also given opportunity to develop their own questions and tests.

This activity provides for small group investigation of the properties of different liquids leading to the discovery that liquids are different in many ways, including density.Students would be led to a very beginning understanding of density.

This activity uses a think-pair-share approach to helping students connect observations about disparate changes in the market for skilled/unskilled labor to long-run trends in wage inequality.

In this interactive lecture, students watch a video clip from The Colbert Report that addresses pollution externalities. Students graph the market and use the write-pair-share technique, then brainstorm ways to move the market to the socially efficient equilibrium.

Students read an article titled "The Sixth Extinction" by Niles Eldredge on past mass extinctions and the current rate of loss of species. The instructor can choose from a suite of activities which include having students respond to discussion and extension questions about the article, write an essay on the article defending Eldredge's view, create an extinction chart, and debate the actions of stakeholders faced with an endangered species vs. human water needs scenario. Students will need to research additional references to complete the activities and be prepared to defend their positions.

This lab activity is designed to have students use their knowledge of balancing and identifying chemcial reactions and apply it in a fun and interesting way!

This activity is an extension of the FOSS Variables Lifeboat investigation. Students choose a lifeboats variable to investigate, write up an experiment based on the variable to be tested, test the variable, and create a lifeboats investigation poster to share their results.

The Fair model web site includes a freely available United States macroeconomic econometric model and a multicounty econometric model. The models run on the Windows OS. Instructors can use the models to teach forecasting, run policy experiments, and evaluate historical episodes of macroeconomic behavior. The web site includes extensive documentation for both models. The simulation is for upper-division economics courses in macroeconomics or econometrics. The principle developer is Ray Fair at Yale University.

This activity teaches students how to formulate research questions and perform empirical analysis. Students analyse family budgets from late 19th-century industrial workers.
