Circuit Game
Source Institutions
In this activity, learners build a game that tests their steadiness. Learners construct the game board by setting up an electrical circuit and a wand.

Rocket Launchers
Source Institutions
In this activity, learners work with an adult to build a rocket and launcher out of a plastic 2-liter bottle, flexible plastic hose, plastic tubing, toilet paper tube, and duct tape.

Cupcake Delivery
Source Institutions
In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

Draft Detectives
Source Institutions
In this two part activity, learners become draft detectives by constructing their own draft catchers to detect drafts around windows or doors.
Currently Working: Testing Conductivity
Source Institutions
Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

Smelly Balloons
Source Institutions
In this activity, learners sniff out scents hidden in balloons! After investigating, learners discover we sometimes can use another sense (smell) to detect things too small to see.

Cookie Mining
Source Institutions
In this activity, learners explore the economics of coal mining as you they use fake money to purchase mining tools, attempt to carefully mine their cookies, sell their chocolate chip ore, and try to

Creepy Crawlers
Source Institutions
Trick your family and friends with this creepy crawler that moves up and down. In this activity, learners construct a circuit and motor device that will move a homemade spider in a spooky way.

Gravity Fail
Source Institutions
In this activity, learners try pouring water out of a regular cup and a miniature cup. It’s harder than it sounds! Learners discover that different forces dominate at different size scales.

Nano Ice Cream
Source Institutions
In this activity/demo, learners discover how liquid nitrogen cools a creamy mixture at such a rapid rate that it precipitates super fine grained (nano) ice cream.

Making a Battery from a Potato
Source Institutions
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
Egg Osmosis
Source Institutions
Visitors observe three beakers. One beaker contains an egg immersed in vinegar. Visitors observe carbon dioxide gas escaping from the shell as the calcium carbonate reacts with the vinegar.
Magnets are Marvelous
Source Institutions
In this activity, young learners investigate magnets. Learners discover that some magnets are stronger than others and that magnets have north and south poles.

Solar Cell Simulation
Source Institutions
In this activity, learners model the flow of energy from the sun as it enters a photovoltaic cell, moves along a wire and powers a load.

Radar Mapping: What's in the Box?
Source Institutions
In this activity, learners mimic remote sensing. Learners use a stick to measure the distance to a "planet surface" they cannot see, and create their own map of the landscape.

Bird Feeder Challenge
Source Institutions
In this activity, learners are challenged to build a bird feeder using recycled materials from home and are encouraged to problem solve during the extensions.

3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.

Echo Base Bobsleds
Source Institutions
The goal of this activity is to build a miniature bobsled that is either the fastest or the slowest. Learners use recycled materials to design, build, and test their bobsled on a bobsled track.

Invisible Sunblock
Source Institutions
In this activity, learners find out why some mineral sunblock rubs in clear. Learners compare nano and non-nano sunblocks and discover how particle size affects visibility.

Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.
