Beating Gravity
The ExploratoriumAdd to list DetailsIn this demonstration, learners watch as a device drops a ball into a cup without touching the ball or cup, even though the ball and cup are virtually side-by-side. Specifically, this device...
Slinky in Hand: Make waves without getting wet
The ExploratoriumAdd to list DetailsPlay with a slinky and make transverse waves. In this simple Exploratorium Science Snack, learners will experience making waves and will learn the different parts of a wave.
Bernoulli Brain Teasers
Smithsonian Center for Education and Museum StudiesAdd to list DetailsIn this activity related to flight, learners conduct two simple tests to explore how lift works. In "Use Your Lips to Levitate," learners hold a piece of paper, blow over the paper, and...
On Target
WGBHAdd to list DetailsIn this design challenge activity, learners modify a cup so it can carry a marble down a zip line and also drop it onto a target. Learners are encouraged to brainstorm answers to design questions,...
Catapults!
Integrated Teaching and Learning Program, College of Engineering, University of Colorado at BoulderAdd to list DetailsLearners build simple catapults and use them to launch cotton balls. Learners can see Newton's second law of motion in effect; pulling the catapult arm back further creates more force and thus...
Magnetic Pendulum
COSIAdd to list DetailsIn this activity about magnetism (page 15 of the PDF), learners will explore how opposite and similar magnetic poles affect a swinging (pendulum) magnet. Learners will see firsthand how gravity and...
Cylindrical Wing
The ExploratoriumAdd to list DetailsIn this design and physics challenge, learners construct a cylindrical wing, fly it, make modifications, and determine how the changes affect flight patterns. This activity introduces learners to...
Squeeze the Stream
Smithsonian Center for Education and Museum StudiesAdd to list DetailsIn this activity related to flight, learners build a tiny stream channel to investigate how fluids (air and water) change speed as they flow between and around objects. It includes an explanation ...
Graph Dance
The ExploratoriumAdd to list DetailsIn this activity, learners "dance" (move back and forth at varying speeds) by reading a graph. This is a kinesthetic way to help learners interpret and understand how motion is graphed....
Bouncing Balls
The ExploratoriumAdd to list DetailsWhen baseball was in its infancy, the ball had plenty of bounce. Today's baseball may not seem to have bounce to it at all; if you drop a ball on the field it won't bounce back. This...
