There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Protons and neutrons and electrons, oh my! Physical science scholars get hands-on with interactive atomic modeling. Starting with a simple helium atom, participants create and name ions, then build isotopes. Questions throughout the...

Learners participate in a series of demonstrations about Bernoulli's principle. They explain how air pressure varies with air speed. They write a detailed lab report about the activity. This is a great way to explore this concept.

This is actually a 10-day mini unit on thermal energy for your high school chemists. Every avenue is taken to get learners absorbed in heat: a pretest, a PowerPoint presentation, Internet exploration, demonstrations, lab activities, and...
