A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

High school physical scientists collide with motion. They work in pairs to design a paper car that will protect a raw egg during a head-on collision. Measurements of distance traveled, time of run, vehicle specs, and photo gate flags are...

The amount of energy Americans use doubles every 20 years. The first lesson plan in a 10-part series teaches scholars about different forms of energy. They rotate through five stations with hands-on activities or experiments at each in...

Life science learners construct lung-o-meters from gallon-sized milk jugs and then measure their lung capacities. For older students, have them graph the vital lung capacities of each person in the class. Cross-curricular pieces are...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...
