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.
Topological Puzzles
Source Institutions
In this activity, learners construct three math puzzles out of simple materials like wood, string, and Styrofoam.
Invent on the Spot
Source Institutions
In this activity, learners design a device to solve a problem: how to get a ball out of a drain pipe.
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.
Levers at Play
Source Institutions
In this activity, learners consider how a simple machine, a lever, turns a small push or pull (a small force) into a larger--or stronger--push or pull (a larger force).
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.
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.
Rubber Band Boat
Source Institutions
In this activity, learners build styrofoam boats powered by twisted rubber bands.
Minibot
Source Institutions
In this activity, learners build a mini dancing robot. This engineering activity introduces learners to electricity, circuits, switches, conductivity, and motors.
Thumb Piano
Source Institutions
In this activity, learners explore sound by constructing a simple piano out of wood and craft sticks.
