The Great Balloon Race
Source Institutions
In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.
Simple Machine Challenge
Source Institutions
In this activity, learners are challenged, using everyday objects, to create simple machines to complete specific tasks.
Finger Knitting
Source Institutions
In this activity, learners will learn how to knit using only their hands. Learners will explore patterns and fabrication as well as develop fine motor skills and patience through this activity.
Opti-Top
Source Institutions
In this activity, learners will create an optical illusion top. Learners will explore color mixing, physics and design through this activity.
Nanoparticle Stained Glass
Source Institutions
In this activity/demo, learners are introduced to the connection between medieval stained glass artisans and nanotechnology.
Hieroglyph Holiday
Source Institutions
In this activity about archaeology, learners will explore different Egyptian hieroglyphs and recognize their meanings and uses.
Marble Ride
Source Institutions
In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.
Clay Bridges
Source Institutions
In this activity, learners make bridges using an oil-based modeling clay (plasticene). The instructions include discussion questions for both before and after bridge building.
Clay Beams and Columns
Source Institutions
In this activity, learners make or use pre-made clay beams to scale and proportion. Specifically, they discover that when you scale up proportionally (i.e.
Electrolysis
Source Institutions
Using electrolysis, learners produce hydrogen gas and oxygen gas from water molecules in a solution.
Shrinkers: Cook up some plastic!
Source Institutions
In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.
Make Pooter
Source Institutions
In this activity, learners will explore engineering to construct an insect collecting tool (insect aspirator). The pooter uses suction to safely collect smaller insects that nets miss or may injure.
Catapult
Source Institutions
In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.
Hail Storm House
Source Institutions
In this activity, learners construct hail-proof houses using recycled materials to discuss storm readiness and safety.
Wind Tube
Source Institutions
In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.
Milli's Super Sorting Challenge
Source Institutions
In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.
Sky Diver
Source Institutions
Students design and build their own parachutes in this hands-on engineering project.
Ships Ahoy!
Source Institutions
Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.
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
