Mint Your Own Coin
Source Institutions
Coins are everyday objects which tell a lot about the people who use them.
Magnus Glider
Source Institutions
A design challenge that takes paper airplanes into an entirely different direction: a magnus glider uses cups and and rubber bands to create a glider that uses the same forces that a curveball (from b
Sand Activity
Source Institutions
In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.
Exploring the Solar System: Pocket Solar System
Source Institutions
“Exploring the Solar System: Pocket Solar System” is a hands-on activity in which visitors make a scale model of the distances between objects in our solar system.
Tricky Tangrams
Source Institutions
In this activity (on pages 49-54 of PDF), learners play with tangrams, a set of triangles, squares and a parallelogram that can combine into a larger square as well as all sorts of other shapes.
Pollution in Our Watershed
Source Institutions
By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from
Klutz-Proof Density Column
Source Institutions
Making liquids of different densities to perfectly lay on top of each other can be a frustrating exercise. The Exploratorium created this activity as a fool proof way of making a density column.
Strong Shapes
Source Institutions
Is a square stronger than a triangle? Use tongue depressors to build simple shapes. Then apply a little weight to them and see what happens!
Anti-Sound Spring
Source Institutions
What happens when two wave pulses meet in the middle? Send waves down a spring to watch them travel and interact.
Take Out the Trash
Source Institutions
Learners explore how recyclers take advantage of the different properties of materials, such as magnetism and density, to separate them from a mixture.
Fair Shares: Predict Equal Shares
Source Institutions
Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

Shadow Puppets
Source Institutions
If you have lights, cardboard, scissors, and some brass fasteners, you can make shadow puppets! Create a story-telling and design challenge for your learners with this simple and creative activity.
Nosedive
Source Institutions
This is a great activity for investigating the basics of lift and drag as they pertain to flight. Learners will discover how to avoid "taking a nosedive" by building their own paper airplane.
Exploring the Universe: Objects in Motion
Source Institutions
"Exploring the Universe: Objects in Motion" encourages participants to explore the complex but predictable ways objects in the universe interact with each other.
