Motion and Inertia
Physics learners make magic with inertia! By pulling paper out from under a stack of blocks or batting a rubber ball into motion, physics scholars' eyes will be opened! Don't think that this lesson is only fun and games; plenty of...
Curated OER
Newton's Second Law
Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

Atmospheric Pressure
Push the envelope with this instructional activity on atmospheric pressure! Your physics or geology juniors will be amazed at your super-human ability as you demonstrate the breaking of a stick using a newspaper! They also work with...
Curated OER
Matter and Energy
Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Gas Laws
A series of attention-grabbing demonstrations and lab activities is outlined in this document. Through them, chemistry kids appreciate the behavior of gases. Inflate balloons, marshmallows, and toothpaste tubes without adding air! Use...
Curated OER
Denial on Trial
What is the "Faurisson Affair”? What is “Holocaust Revisionism”? What does freedom of speech entail? Do revisionists have a right to voice their ideas? Such questions are at the heart of a richly detailed, thought provoking lesson...
Curated OER
Proof of the Pythagorean Theorem Using Transformations
Middle and high schoolers construct a triangle using Cabri Jr. They construct squares on each of the legs and hypotenuse of the triangle. Pupils show that the area of the squares on the leg equal the area of the square on the hypotenuse.
