Hovercraft
Source Institutions
In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.
Water Wire: Electricity Flowing Through Water
Source Institutions
In this activity on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.
Salts & Solubility
Source Institutions
In this online interactive simulation, learners will add different salts to water and then watch the salts dissolve and achieve a dynamic equilibrium with solid precipitate.
Deep Sea Diver
Source Institutions
In this ocean engineering activity, learners explore buoyancy and water displacement. Then, learners design models of deep sea divers that are neutrally buoyant.
Get-Moving Game
Source Institutions
In this invention challenge activity, learners create an indoor game for one or two people that gets you moving.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
Pedal Power
Source Institutions
In this engineering activity, learners examine bicycle mechanics and gear ratios. Learners determine which gears will help them bike a set course in the shortest amount of time.
ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Bubble Trouble
Source Institutions
In this activity on page 15 of the PDF, learners measure the amount of bubbles that they make using a detergent.
Does Size Make a Difference?
Source Institutions
In this activity on page 15 of the PDF, discover how materials and physical forces behave differently at the nanoscale.
Paddle Power
Source Institutions
In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.
Paper Bridge
Source Institutions
In this engineering activity, challenge learners to construct a paper bridge that can support 100 pennies.
Electric Gamebox Challenge
Source Institutions
In this design challenge activity, learners invent a pinball-like game where a kick stick hits a ping pong ball into a target that buzzes.
Kinetic Sculpture
Source Institutions
In this design challenge activity, learners build a tower that’s at least 12 inches high with two or more parts that move (spin, sway, or flap) in the wind.
Dance Pad Mania
Source Institutions
Make your own "Dance Dance Revolution" dance pad! In this design challenge activity, learners work in teams to build a dance pad that lets you use your feet to sound a buzzer or flash a light.
Zip Line
Source Institutions
In this design challenge activity, learners build a device to carry a Ping-Pong ball from the top of a zip line to the bottom in four seconds (or less!).
Marble Ride
Source Institutions
In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.
Build a Band
Source Institutions
In this design challenge activity, learners build a four-stringed instrument that can play a tune.
Watercraft
Source Institutions
In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.
High Rise
Source Institutions
In this design challenge activity, learners build a tower that can support a tennis ball at least 18 inches off the ground while withstanding the wind from a fan.
