Linkages
Source Institutions
This design challenge is an open-ended exploration of linkages, a group of parts connected by hinges, and the types of motion they can create.
Parachutes
Source Institutions
In this activity, learners will investigate air and gravity through the use of various fabrics by through them in the air. Activity includes step-by-step instructions and extension ideas.
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.
Pendulum Fun
Source Institutions
In this activity, learners will explore pendulum motion through scientific trials by using household items with different length strings.
Crank It Up
Source Institutions
In this engineering activity, learners explore simple machines and then build cardboard automata using cams.
Rocket Reactions
Source Institutions
The "Rocket Reactions" activity is an exciting way to learn about how materials interact, behave, and change.
Four Corners
Source Institutions
In this design challenge activity, learners build a machine out of cardboard that runs smoothly and dependably. Learners must be precise to make sure their component works properly.
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.
Helping Hand
Source Institutions
In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.
My Solar System
Source Institutions
In this online activity, learners build their own system of heavenly bodies and watch the gravitational ballet.
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.
What Counts in Bounce
Source Institutions
In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.
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.
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.
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!).
Molecules in Motion
Source Institutions
"Molecules in Motion" explores how materials behave and change in a vacuum.
Sky Glider Challenge
Source Institutions
In this design challenge activity, learners use two helium-filled balloons to build a blimp that can travel in a straight path across the room.
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.
Masses & Springs
Source Institutions
In this online activity, learners use a realistic mass and spring laboratory. They hang masses from springs and adjust the spring stiffness and damping.
Confetti Launcher
Source Institutions
Hooray! In this design challenge activity, learners invent a device that launches a spoonful of confetti into the air. Learners are encouraged to create the biggest cloud of confetti possible.
