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.
Tumble Wing Walkalong Glider
Source Institutions
In this physics activity (page 2 of the PDF), learners will construct their own walkalong glider. They will explore how air, though invisible, surrounds and affects other objects.
Hot Air Balloon
Source Institutions
In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.
Diving Submarine
Source Institutions
Learners use a commercially available toy to experiment with density. They fill a chamber in the toy submarine with baking powder and release it into a tank of water.
Go Fly a Kite
Source Institutions
In this hands-on activity, children create their own kites that can fly indoors. Learners are exposed to basic concepts of gravity and air resistance.
Puff Mobile
Source Institutions
In this engineering activity, challenge learners to design a car using only 3 straws, 4 Lifesavers™, 1 piece of paper, 2 paper clips, tape, and scissors.
Film Canister Rocket
Source Institutions
In this activity, learners construct and launch rockets using simple materials and their understanding of chemical reactions.
Fly a Hot-Air Balloon
Source Institutions
Learners assemble a hot-air balloon from tissue paper. The heated air (from a heat gun) inside the balloon is less dense than the surrounding air and causes the balloon to float.
Balloon Car
Source Institutions
In this activity, learners explore force and motion by constructing cardboard cars that are propelled by balloons.
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.
Flubber
Source Institutions
Learners experiment with a piece of Silly Putty® by stretching, bouncing, and snapping it. They then create flubber, a similar substance, by mixing diluted glue and a solution of sodium borate.
