If Hot Air Rises, Why Is it Cold in the Mountains?
Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.
Science 4 Inquiry
States and Phases of Matter
Plasma is the most common phase of matter in our universe. Scholars explore the change of energy as molecules change phases of matter. They rotate through stations, graphing the changes in energy level.
