Make a Comeback Can
Source Institutions
Learners build a can that automatically returns after being rolled away. The can has a rubber band inside that stores energy as the can rolls one direction.
Egg Drop
Source Institutions
Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.
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.
Measure the Pressure: The "Wet" Barometer
Source Institutions
In this activity, learners use simple items to construct a device for indicating air pressure changes.
Pop Bottle Whirligig
Source Institutions
Learn about friction and kinetic energy with this cool spinning toy.
Hoop Glider
Source Institutions
In this activity, learners engineer a flying glider using paper hoops and a drinking straw.
Balloon Car
Source Institutions
In this physics activity, challenge learners to make and race a balloon-powered car. Learners construct the body out of a paper cup, wheels out of wooden spools. and fuel tank out of a balloon.
Pencil Balance
Source Institutions
In this activity, challenge learners to make a pencil stand on its tip using only two pieces of wire and two clothespins. Use this activity to demonstrate the center of gravity.
Why do Hurricanes go Counterclockwise in the Northern Hemisphere?
Source Institutions
In this kinesthetic activity, learners will play a game with a ball to demonstrate the Coriolis force, which partly explains why hurricanes in the Northern Hemisphere rotate counterclockwise.
Shake it up with Seismographs!
Source Institutions
In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.
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.
Catapult
Source Institutions
Build a catapult that transforms the potential energy of a twisted rubber band into kinetic energy. Experiment with design variations so that you can hit a target with a projectile.
Build a Bubble Circuit
Source Institutions
In this engineering design challenge, learners make a bubble maze that allows bubbles to move through a series of “on” and “off” switches.
All Wound Up
Source Institutions
In this activity, learners build a racecar using only a rubber band, spool, straw, and paper clip! This racer is a classic toy that zips across a flat surface.
Get a Leg Up
Source Institutions
In this activity, learners experiment and collect data during a simulation of the fluid shifts experienced by astronauts' bodies in microgravity.
Build a Big Wheel
Source Institutions
In this activity, learners explore how engineers have developed big wheels or Ferris wheels.
Reusable Rockets
Source Institutions
This activity (located on page 3 of the PDF under GPS: Garbology Activity) is a full inquiry investigation into design optimization using recycled materials.
Two Ball Bounce
Source Institutions
This is a quick, yet dramatic activity/demonstration that introduces learners to the concept of energy transfer. A small ball is placed on top of a large ball and both are dropped together.
Micro Automata
Source Institutions
In this activity, learners build small animated toys that move.
