In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity, learners take apart a used zinc-carbon dry cell battery.

Based of the The Tech Challenge 2015, learners will engage in two mini-design challenges related to seismic engineering.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

In this activity, learners discover the principles of edible glass by making a supersaturated sugar solution.

In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.

Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

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

In this activity, learners will explore how and why weight distribution works.

In this activity, learners explore the principles of magnetism by observing how various materials interact with magnets and superconductors.

Build a phonograph record player using a cactus needle, a record, LEGOs gear box, and a piece of paper! This activity uses a Pico Cricket to turn the motor.

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

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

Make a cuíca (“kwee-ka”), a traditional Brazilian musical instrument that originated in Africa. Played primarily in Brazil, now you can play it at home, too, with this Exploratorium produced activity.

In this activity, learners demonstrate the effects of cold-working (strain-hardening) and annealing. Learners discover that these processes change the load that a wire can support.

In this activity learners will build roller coasters and test them using small balls or marbles.

In this activity, learners investigate the basic crystal structures that metal atoms form.

This game uses a modified Uno deck to review concepts related to stem cell research and diabetes.

In this activity, learners discover that some plastics will shrink when you get them hot. Learners bake polystyrene in a regular oven and discover what happens.
