The Great Escape

I would weigh less on the moon? Send me there, then! On the top of the first page, a cartoon image demonstrates the difference between Earth and the moon. It then goes on to describe weight and mass and provides five practice problems...

What a great idea for scientific inquiry. This lab was intended for use as children explored a college campus, but it could be used anywhere. They go to three different places on campus and conduct a simple experiment that shows an...

Don't fall for these common misconceptions about falling objects! Using two sports balls with different masses, the interviewer demonstrates in a brief video the forces at work. Participants marvel as a much-heavier medicine ball lands...

May the force be with you! Learn how to present the content of PS2A, Forces and Motion, using the strategies in the video. With fun scenarios that include Angry Birds and toilet paper, demonstrating the relationship between force, mass,...

Does size or mass impact gravitational pull? Scholars experiment with force pairs to answer that question. They can change the size, mass, and distance between the objects using an engaging simulatoin. This allows pupils to visualize the...

What a wonderful way to explore motion and forces! Learners design a catapult, after watching a video and discussing types of catapults. This is a comprehensive and complete lesson with links to supplementary resources.

Looking for a quick way to supercharge your electricity and magnetism unit? Assign a very responsive interactive designed to illustrate the relationship between charge, electric field, and the resulting forces. Learners experiment with...

Cover standards for middle school force, mass, and the motion of an object with this site. Find work samples, phenomena, assessment templates, and videos that directly address standard.

Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

Have you ever wanted to turn off gravity? This simulation allows learners to do just that in addition to altering other variables. Scholars can move the sun, Earth, moon, and space station to see how distance affects gravitational pull....
