Gravity Video


Head to PBS Learning Media for a great QuickTime video and some background information on centripetal force, courtesy of the PBSKids program ZOOM.

If you are a bit fuzzy on Newton's and Einstein's theories of gravity, this short video from NOVA explains it clearly.

Gravity Lesson Plans!


HotChalk has a great lesson plan for understanding gravity, similar to the experiment that Galileo did from the Leaning Tower of Pisa. Watch Galileo's classic experiment re-enacted in this BBC video.

Bright Hub Education offers a lesson plan titled, "An Experiment on the Center of Gravity." Kids can compete against adults and win at these activities. Fun activity for your class.

Check out this lesson on the forces of gravity from Utah Educational Network.

Students can observe the effect of gravity on water in this hands-on lesson plan from Scholastic.

In this lesson from Wonderville, students explore the principles behind force and gravity as they experiment with projectiles and catapults.


Check out this terrific site from the Minnesota Science Teachers Education Project. A collection of hands-on activities and experiments for grades K-12.
