Gravity: It's GREEEAAATTT!

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,...

Falling objects can be brutal if you don't protect your noodle! Scholars explore the motion of falling objects through measuring short intervals to determine if the distance traveled varies with time. Building off of this, scholars...

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...

Where is gravity when you need it? Explore Earth's hold on the astronauts at the International Space Station. The narrator of a short video asks museum visitors why they think the astronauts float when they are still very close to Earth....

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...

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...

Amaze your class with this demonstration of gravity and friction. A ring on a string is able to catch a spool of tape as it falls. This is a perfect introduction for a class discussion on these topics, or you could have kids them try it...

Although gravity is something everyone experiences, many have misconceptions tied to the concept. A PD lesson from the Good Thinking series explores misconceptions and how to correct them. The lesson also offers ideas for demonstrations...

Through a series of experiments and demonstrations, fifth graders will learn about gravity. They will make predictions, drop various objects, write down their observations, and try to understand gravity through balance. This...

Whether or not Galileo actually dropped balls from the Leaning Tower of Pisa, this demonstration will solidly demonstrate that objects are accelerated at the same rate, regardless of mass. You will, however, need a vacuum pump and a few...
