Gravity

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...

Here is a fabulous set of teacher's notes that will make your next hands-on gravity and force lab fun and interesting. These notes provide you with three activities that allow children to make and test hypothesis regarding force,...

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...

How do you describe gravity? Physics scholars watch as the narrator asks passers-by to try their hand at summing up a common force. The amusing answers focus on attraction and mass.

Does space have its own gravity? And, if so, why do astronauts just float around in the space station? Science sleuths examine the forces acting upon astronauts in the International Space Station with help from the narrator. He...

Explore the effects of gravity using this demonstration on surface tension. Learners fill a glass with water, put a handkerchief over the top creating a seal, and then turn the glass over without losing a drop. This is a terrific way to...

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...

Learners read a short description about gravity and what it does and then explore the two ideas about how gravity works. After gaining a better understanding of the concept, individuals participate in a thorough experiment on what would...
