Magnetic Spinner & Compass
Source Institutions
Learners use shop tools and various materials to construct a magnetic spinner and a compass.
Tops
Source Institutions
In this activity, learners discover that some things only stand up while they are spinning.
Two Washers
Source Institutions
In this activity, learners create a mind and math puzzle that requires a three-dimensional solution.
Matraca
Source Institutions
In this activity, learners create a traditional Mexican noisemaker (a matraca) using cardboard, craft sticks, and a wooden dowel.
Zig Zag Bopper
Source Institutions
In this activity, learners build a machine made of craft sticks to multiply the levering motion of their hands and create a device that bends and extends.
Stereoscope
Source Institutions
In this activity, learners construct a device that allows them to view 2-D images in 3-D.
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.
Lever Cowboy
Source Institutions
In this activity, learners build a figure that moves and "comes to life" when they pull its string.
Newton's Cradle
Source Institutions
Build your own version of the classic physics toy using simple materials.
Marble Drop Game
Source Institutions
Build your own version of a favorite carnival game, in which a marble races down a maze consisting of rows of nails.
Handheld Water Bottle Rocket & Launcher
Source Institutions
In this activity, learners build handheld rockets and launchers out of PVC pipes and plastic bottles. Use this activity to demonstrate acceleration, air pressure, and Newton's Laws of Motion.
Wind Tube
Source Institutions
In this activity, learners explore moving air and the physics of lift and drag by constructing homemade wind tunnels.
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.
Gymnast
Source Institutions
In this physics activity, learners build a toy with a figure that spins around like a gymnast on the high bar.
Geometry Construction: Polyhedral Playthings
Source Institutions
In this activity, learners create 3D geometric shapes using straws and pipe cleaners.
Games of Chance and Brains
Source Institutions
In this activity, learners build and play three math games. In the first game, called "Switcheroo," learners place marbles in holes 1 through 4 and 7 through 10.
Electromagnetic Dancer: Connect Her Up and Watch Her Dance!
Source Institutions
In this activity, learners use a nail and magnet wire to build an electromagnet, which controls the movements of a paper dancer.
Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Topological Puzzles
Source Institutions
In this activity, learners construct three math puzzles out of simple materials like wood, string, and Styrofoam.
Hydraulic Car
Source Institutions
In this activity, learners build cars using syringes and water-powered hydraulics. Learners construct the car frame out of cardboard and set up a hydraulic system to raise and lower the car.
