Paddle Power
Source Institutions
In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.
Getting Your Bearings
Source Institutions
In this activity, learners explore the concept of friction and how ball bearings reduce friction.
Pulleys and Force
Source Institutions
In this activity, learners explore the concept of force and how pulleys are used in everyday life to make work easier.
Stranded
Source Institutions
What's a more compelling problem to solve than being stranded on a deserted island?
Marble Ride
Source Institutions
In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.
Telescoping Periscope
Source Institutions
In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.
Dowels and Rubber Bands I
Source Institutions
If you have 3-foot dowels and rubber bands, you can can started on this fun and open design challenge. You can make structures big and small: make it so you can fit your parent into it!
Cranking Bird
Source Institutions
In this activity, learners build a mini crank machine to make a bird "fly." This engineering activity introduces learners to automata, rotational motion, cranks and cams.
Mitten Challenge
Source Institutions
In this activity, learners try to put together toy bricks—wearing oven mitts on their hands! This activity shows learners how difficult it is to build small things when your tools are too big.
Design a Safer Bicycle Helmet
Source Institutions
In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.
Space Origami: Make Your Own Starshade
Source Institutions
In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
Building A Storm Drain
Source Institutions
In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.
Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.
Family Flyers
Source Institutions
In this activity, learners work in teams to build and test paper airplanes. Learners try to fly their airplanes directly on the runway and earn points for accuracy.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
Lifting with Levers!
Source Institutions
In this fun hands-on activity learners explore a simple machine: the lever. What happens to a load when you multiply the length of a lever? Find out here!
Liquid Body Armor
Source Institutions
In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.
Crash Landing!
Source Institutions
In this activity, groups cut out and sort cards showing items recovered from a crash landing on the Moon. The 12 items range from food and water to rope and matches to a self-inflating life raft.
What Gives?
Source Institutions
In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.
Electric Switches
Source Institutions
In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.
