Not finding what you're looking for? A few suggestions:
• Fewer words might give better results. Look up cats instead of funny cats.
• No need to search with the words videos or for kids included.
• Use related words: If searching for iceberg isn't working, try ice or glacier.
• Is everything spelled correctly?
• Browsing topics might help, too!

Observing the angle of repose with DIY physics devices
The angle of repose or critical angle of repose is how steep various types of materials can be piled without slumping. The steepness of the side of a pile is determined by the amount of friction between the particles ...
The Coupled Pendulum, a physics demonstration
See the simple laws of physics at work: Two pendulums swing on a string, transferring energy from one to the other and back again. This demonstration by MarkHacks, made with cardboard, screw hooks, tape, string, and t...
Homemade marble track demonstrations by science teacher Bruce Yeany
Science teacher Bruce Yeany uses this collection of physics marble tracks to introduce and reinforce his students' ideas about perpetual and kinetic energy, motion, acceleration, inertia, and more. The tracks—stringle...
Make Lissajous patterns with DIY sand pendulums or light
Sand pendulums are an easy and beautiful method for students of all ages to learn a bit about the harmonic motion. These devices are easy to build and can be adjusted to give a variety of patterns. A pendulum that beg...

A home made string shooter & slow moving waves in rope
This string shooter uses two wheels on motors to push a string forward while a tube guides the string back through the wheels, creating a constant loop that appears to defy gravity and demonstrates wave phenomena. ...
Rock Swing Cup & more DIY playground physics
Next time you're on the swings, think about what it might be like if you were swinging on the moon, free from air resistance. AP Physics teacher Jared Keester had that in mind during this experiment: Swing jumping wit...
Fourth graders create a solar powered classroom
When Aaron Sebens started talking about renewable energy with his fourth grade class, they kept coming back to their excitement about solar power and making it a more hands-on learning experience. How might they move ...
Build your own space-time warping demo for the classroom
Physics Teacher SOS workshop leader Dan Burns demonstrates how he uses stretched spandex lycra, weights, marbles, and gravity in his high school classes to make this impressive space-time wa...
Pardon My Dust – Dynamic Sketching with Peter Han
Start with large basic shapes, add details after, have fun with the process, and then let go of it and try again. In Pardon My Dust, by director Adriel de la Torre, watch Dynamic Sketching teacher Peter Han illustrat...
2,000 ping pong balls and 30 middle-school teachers in Zero G
Because 2,000 ping pong balls and 30 middle-school teachers floating in “zero gravity” isn’t something you see everyday, the kids should watch (or rewatch!) this 2010 ScienceBob video. From northrop...
Liquid Nitrogen and 1500 Ping Pong Balls
Dr. Roy Lowry of Plymouth University in the UK made science explosively exciting for his class by demonstrating how powerful (and loud) it can be when the pressure of cold, trapped Liquid Nitro...
