Waterless Snow Globe
Source Institutions
In this activity, learners will investigate static electricity as they create waterless snow globes.

Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.

Tumble Wing Walkalong Glider
Source Institutions
In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.

How to Learn Basic Shapes by Making a Shape Mobile
Source Institutions
In this activity, caregivers and young learners work together to craft and talk about shapes and relative positions of such shapes by creating a mobile.

Polymers are Chains (K-2)
Source Institutions
In this activity, learners make a paper model of a polymer, then make Silly Putty, an actual polymer.

Pop Bottle Whirligig
Source Institutions
Learn about friction and kinetic energy with this cool spinning toy.

Spool Racer
Source Institutions
In this physics activity, challenge learners to make a rubber band-powered spool racer. Demonstrate principles of motion as well as potential and kinetic energy.

Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.

Flubber: Make a polymer!
Source Institutions
This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.

Can Car
Source Institutions
In this physics activity, challenge learners to make a race-car out of a coffee can and rubber band. Demonstrate motion, forces, kinetic and potential energy and friction.

Slime
Source Institutions
Learners make slime from white school glue and Borax detergent. The long chain molecules of the white glue become cross-linked by the Borax into a big network.

Make a Comeback Can
Source Institutions
Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.

Brick Drop Challenge
Source Institutions
In this design challenge, leaners attempt to build a strong structure out of LEGO® bricks that can withstand a 4-foot drop.

Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.

Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.

Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

Ramp Racers
Source Institutions
In this activity about friction and gravity (page seven of the pdf), learners use toy racing cars to explore how the two forces affect the motion of objects.

Zipline
Source Institutions
In this design activity, learners create a vehicle that can transport a load, like a favorite toy or as a recycled object, from the top of a zipline to the bottom using only gravity.

Thaumatrope
Source Institutions
In this activity, learners make an optical illusion toy from the 1800s to explore persistence of vision.
