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.
Pencil Balance
Source Institutions
In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.
Magnetic Marble Run
Source Institutions
Learners explore magnetism and motion as they build a simple marble run. Learners test different arrangements of plastic and cardboard tubes, bottles, and cups on a magnetic board.
If You Lived in a Forest
Source Institutions
This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.
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.

Giant Museum: Create a Scale Model
Source Institutions
In this activity, learners will predict the size of a giant scale model of a comb or other rectangular object, then make one. If you tripled the size of a dollar bill, could you sit on it?
Soaring Towers: Building with Recycled Materials
Source Institutions
In this activity, learners will build the highest tower they can out of recycled materials.
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
Watch and Create! Creativity For Sustainability
Source Institutions
In this activity, children and adults work together to explore their relationship with technology and examine ways to make sustainable media consumption choices.
Mini Zoetrope
Source Institutions
In this activity (posted on March 27, 2011), learners follow the steps to construct a mini zoetrope, a device that produces an illusion of action from a rapid succession of static pictures.
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
Yeast Balloons
Source Institutions
Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.
Silly Putty Investigation
Source Institutions
In this activity (located on page 7 of PDF), learners explore how Silly Putty was first invented and then attempt to make a batch of their own.
Bark Beetle Infestation Investigation: Estimation and Pheromones
Source Institutions
This activity investigates how bark beetles can threaten forests by having learners estimate the number of infected trees from a photo.
Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.
Rockets Away!
Source Institutions
In this activity, learners work in teams to construct and test fly drinking straw rockets. Learners explore how changing the rockets' fins affect flight distance.
Wet Art
Source Institutions
In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.
Paper Bridges
Source Institutions
In this activity, learners build bridges using paper and explore how much weight each bridge design can support.
