Gravity

Between the pull of gravity and the push of air pressure, it's a wonder animals can balance or move at all. With a hands-on lesson about the center of gravity, learners discuss their own experiences with the topic, then work with...

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

Check out a lesson plan that starts with force of gravity and moves through the concepts of mass, weight, volume, and density. Learners calculate density, test the buoyancy of objects, and then demonstrate understanding by altering the...

Test the limits of gravity while encouraging full class participation with this thrilling lesson. Pupils investigate the meaning of work and how it is equivalent to energy. They explore the joule and apply it as a unit of work. They...

Students apply their knowledge of friction, drag, mass and gravity as they design, build, and test mini-bobsleds.

When you lecture on the center of mass and center of gravity, show this presentation as a note-taking guide for your physical science class. Pause at the fifth slide to let them find the center of mass for their pencils. Also ask them...

Gravity impacts the way you throw a ball and the way the Haumea travels around the sun. The video introduces gravity as a force. It describes the various types of orbits, escape velocity, and weightless mass. 

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...

Scientists state that the higher something is above the earth, the greater the gravitational potential energy. Does this mean there is more gravity acting on the moon than on an apple falling from a tree? Scholars adjust the distance...

Groups simulate an orbit using a piece of string and a water balloon. Individuals spin in a circular path and calculate the balloon's velocity when the clothes pin can no longer hold onto the balloon.
