Floating Head Cup
Source Institutions
In this activity, learners watch a figure "magically" float up through the air.
Tube Zither
Source Institutions
In this activity, learners explore sound by constructing tube zithers, stringed instruments from Southeast Asia and the South Pacific.
PVC Water Squirter
Source Institutions
In this activity, learners build a water squirter using a PVC pipe, dowel, and foam. This activity is great for the summer time and introduces learners to forces and water pressure.
Spinning Illusions
Source Institutions
In this activity, learners construct three optical illusion toys to examine how our brains play tricks on what we see.
Floating Butterfly
Source Institutions
In this activity, learners create a cool floating animal using the science of magnetism. Learners discover what happens when a piece of magnetic metal enters a magnet's field.
Motorized Balancing Toy
Source Institutions
In this activity, learners build a toy that flies in circles. This activity introduces learners to center of mass, torque, and rotational motion.
Digger
Source Institutions
In this activity, learners build their own construction cranes using tongue depressors and pushpins.
Balloon Car
Source Institutions
In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.
Slide Whistle
Source Institutions
In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.
Finger Basketball
Source Institutions
In this activity, learners build mini-basketball courts using cardboard and measuring spoons. Use this activity to introduce learners to catapults, forces, and levers.
Rolling Returns
Source Institutions
In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.
Weather Vane
Source Institutions
In this meteorology activity, learners build weather vanes using straws, paperclips, and cardstock.
Torsion Drum
Source Institutions
In this activity, learners build a musical drum using a cardboard tube, plastic wrap, and beads.
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.
Hovercraft
Source Institutions
In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.
Bag Pipe
Source Institutions
In this activity, learners explore sound by constructing their very own bagpipe instrument.
Magnet Tower
Source Institutions
In this activity, learners build magnetic towers to explore the forces and properties of magnets.
Chirping Bird
Source Institutions
In this activity, learners build a cuica or chirping bird using straw, string, and a bottle cap. Use this activity to explore the interplay of motion and sound.
Squidgy Slime
Source Institutions
In this chemistry activity, learners transform two ingredients (4% polyvinyl alcohol solution and 4% borax solution) into gooey slime.
Weather Vane and Anemometer
Source Institutions
In this meteorology activity, learners construct simple devices to measure the direction and speed of wind.
