Earth Walk
Source Institutions
In this hands-on and feet-on excursion, learners take a science walk to visualize the planet's immense size and numerous structures, without the usual scale and ratio dimensions found in most textbook

Color Contrast
Source Institutions
Do you have a hard time matching paint swatches with your furniture? When you consider human perception, color is context dependent.

Magnetic Shielding: Magnetic lines stop here
Source Institutions
Testing magnets is always a fun pastime, but here, we're going beyond "will it attract the magnet?" In this activity, learners will investigate which materials allow magnetic fields to pass through or

Egg Bungee
Source Institutions
Learners attach an egg to a rubber-band bungee cord and drop the egg.

Mighty Molecules
Source Institutions
In this activity, learners use marshmallows and gum drops to construct seven models of molecules. Learners classify (solid, liquid or gas) and draw diagrams of the molecules.

Getting There!: Navigation and Trajectory
Source Institutions
In this two-part activity, learners map a navigation plan to get from Earth to Mars and back. In activity one, learners represent the orbital paths of Earth through dance and dramatic movement.

Modeling the Night Sky
Source Institutions
In this two-part activity, learners explore the Earth and Sun's positions in relation to the constellations of the ecliptic with a small model.
Ships Ahoy!
Source Institutions
Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.
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.

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.

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.

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.

You Can Say That Again!: Text Compression
Source Institutions
This activity helps students learn how computers "compress" text by identifying repeating patterns of letters, words, and phrases.

Rock Bottoms
Source Institutions
Learners add acid rain (nitric acid) to two cups that represent lakes. One cup contains limestone gravel and the other contains granite gravel.

Get In The Game
Source Institutions
In this design challenge, learners will use computational thinking to design their own board game.
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.

Foam Peanuts
Source Institutions
Learners compare the properties and solubilities of Styrofoam (TM), ecofoam packing peanuts, and popcorn. First, the solubility of each substance is tested in water.

Melting Ice
Source Institutions
In this activity, learners explore density, convection, stratification, and, by inference, the melting of icebergs. Learners make hypotheses, test their hypotheses, and explain their observations.

Rock Candy
Source Institutions
In this yummy chemistry activity which requires adult supervision, learners use sugar and water to explore how crystals form.
