What Makes a Gas, a Greenhouse Gas?—The Carbon Dioxide Dance
Investigate a heated topic in environmental science. Scholars team up to play the parts of gas molecules in the atmosphere. As the teacher moves about, acting as the electromagnetic wave, learners react as their molecules would to the...
Exploratorium
Hot Spot
Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.

Good Vibrations
Students demonstrate sound waves and make changes in the waves
resulting in changes in pitch. Students associate changes in pitch in various "musical instruments"with size and shape and the sound waves they produce.
Curated OER
Circuit Lab
Students explore the properties of electricity. This lab shows students the need for a circuit in order to have a flow of electricity. It demonstrates Ohm's law, which relates voltage, current, and resistance.
