Motion Picture
Source Institutions
During this hands-on activity, learners are briefly exposed to moviemaking and animation, when they create their own thaumatropes.

Shadow Puppets
Source Institutions
In this activity, learners will create their own simple shadow puppets, and experiment with light and shadow while playing with them.

Boomerang
Source Institutions
Learners trace, cut out and fly a boomerang, outdoors or in a large indoor space.

Build a Bell Bracelet
Source Institutions
Learners make bell bracelets, place them on their wrists or ankles, and then dance to the rhythms and sounds the bells make. Many cultures use ankle or wrist bells to make music during dancing.

Hang Time
Source Institutions
Learn how to make and fly a paper helicopter! This simple activity includes a template (for the copter "blades") and instructions for folding, flying, and testing designs.

Set It Straight
Source Institutions
In this activity, learners build a simple tabletop seesaw to test how different variables (the position of the fulcrum, distance, weight) affect its balance under increasing weight loads.

Action Figure
Source Institutions
In this project, students explore how levers work, by making a puppet with moving limbs.

Phenakistascope
Source Institutions
In this optics activity, learners build an animation tool to make mini movies. When you spin a phenakistascope, the pictures move so quickly that your eyes and brain can't separate the images.

Bearings for Your Whirligig
Source Institutions
Experiment with friction and make bearings for a whirligig! This activity is a nice introduction to friction and bearings and demonstrates why bearings are useful for spinning.

Screaming String Thing
Source Institutions
In this simple and fun activity, learners discover the relationship between vibration and sound by making a squeaky toy instrument out of simple household materials.

Helicopters
Source Institutions
In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

Spinning Tops
Source Institutions
Create your own spinning top, and explore color, shapes and spinning. This activity contains instructions for making your spinning top, and tips on how to design and decorate it.

Straw Kazoo
Source Institutions
In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

Straw Pipes
Source Institutions
Learners build pan pipes out of drinking straws by cutting them to different lengths. Then, learners make music by blowing across the straws and playing some well-known songs.

Sidewalk Chalk
Source Institutions
In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

Waterbottle Membranophone
Source Institutions
In this activity, you'll use a straw, a water bottle and a paper tube to make an instrument that's very much like a saxophone.

Make a Garbage Bag Kite
Source Institutions
Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!

All Wound Up
Source Institutions
In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.

Marble Game
Source Institutions
In this activity, learners construct a simple game to test their hand-eye coordination and steadiness of hand.

Origami Flying Disk
Source Institutions
In this three-part activity, learners use paper to explore Bernoulli's Principle — fast-moving air has lower pressure than non-moving air.
