In this activity, students participate in a series of timed relay races using their skeletal muscles. The compare the movement of skeletal muscle and relate how engineers help astronauts exercise skeletal muscles in space.

That heat flows from hot to cold is an unavoidable truth of life. People have put a lot of effort into stopping this natural physical behavior, however all they have been able to do is slow the process. Student teams investigate the properties of insulators in their attempts to keep cups of water from freezing, and once frozen, to keep them from melting.

Students will learn the difference between global, prevailing and local winds. In this activity, students will make a wind vane out of paper, a straw and a soda bottle and use it to measure wind direction over time. Finally, they will analyze their data to draw conclusions about the prevailing winds in their area.

Students build their own simple conductivity tester and explore whether given solid materials and solutions of liquids are good conductors of electricity.
