Students watch a demonstration that introduces them to the idea that friction is a force that impedes motion when two surfaces are in contact. They work in groups to experiment with frictional force using a coffee cup on which they alter...

Students work together to build their own spaghetti bridge. They test the bridge to see how much weight it can hold before breaking. They discover how engineers use this type of information to design bridges.

Students explain what inertia is in their own words. For this physics lesson, students investigate how Newton's first law applies to their robot. They discuss real world examples of the 1st law.

Middle schoolers discover the cuases of pollution. They investigate different pollutants that exist. Stsudents research technologies developed by engineers to reduce the amounts of air pollution. Upon completion of assigned...

Students will use components to make a balanced decision. They will be able to rationalize their own decisions while understanding the perspectives of others. They will then develop criteria to quantify their decisions.

Students examine the effects of bycatching on water environments. They discover how echolocation works. They participate in a simulation of the process to use it while walking blindfolded.
