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.
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.
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
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.
3-2-1 POP!
Source Institutions
In this physics activity, learners build their own rockets out of film canisters and construction paper.
Full of Hot Air: Hot Air Balloon Building
Source Institutions
In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.
Cook Up a Comet
Source Institutions
In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
Block Neighborhood
Source Institutions
In this activity learners will build a neighborhood out of blocks and cardboard.
Puppet Play
Source Institutions
In this activity, learners will make a marionette puppet and put on a show. Learners will explore color, design, fabrication and storytelling through this activity.
Roller Coasters
Source Institutions
In this activity learners will build roller coasters and test them using small balls or marbles.
Wind Tunnel
Source Institutions
Scientists use enormous wind tunnels to test the design of planes, helicopters, even the Space Shuttle.
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.
Make a Mobile!
Source Institutions
In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.
Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.
Ramps 2: Ramp Builder
Source Institutions
In this inquiry-based learning activity, learners design, build, and test their own ramps. They are introduced to a variety of materials and explore putting them together.
Safe in the Sun
Source Institutions
In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.
Invent on the Spot
Source Institutions
