Blast Off!
Source Institutions
Students design and create their own air-powered rockets, in this hands-on activity.
Pinball Wizard
Source Institutions
In this hands-on engineering project, kids use two simple machines, levers and inclined planes, to construct their own pinball machines.
Hovercraft
Source Institutions
In this activity, learners make plates levitate! Learners build "hovercrafts" using simple materials to explore friction and motion.
What Gives?
Source Institutions
In this activity, learners design, build and test a model suspension bridge for sturdiness and strength.
Water Filter
Source Institutions
In this engineering activity, challenge learners to invent a water filter that cleans dirty water.
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.
Toy Chemistry
Source Institutions
In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.
Race for Survival
Source Institutions
During this interactive "survival" game, students learn about the importance of camouflage and how it helps animals to blend into their surroundings, as either predator or prey.
ZOOM Glue
Source Institutions
In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.
Eye Spy
Source Institutions
This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.
As Straight as a Pole
Source Institutions
In this engineering activity (page 3 of PDF), young learners investigate how a pole can be made stable by “planting” its base in the ground or adding supports to the base.
Designing a Wall
Source Institutions
In this engineering activity (page 5 of PDF), young learners investigate how materials and design contribute to the strength of a structure, particularly walls.
Egg Bungee Jump
Source Institutions
In this activity, learners design a bungee jump for an egg using nylon stockings.
Rescue Mission
Source Institutions
In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.
Marble Ride
Source Institutions
In this activity, challenge learners to design a roller coaster ride for a marble using cardboard and other simple materials.
Sky Diver
Source Institutions
Students design and build their own parachutes in this hands-on engineering project.
Balloon Flinker
Source Institutions
In this activity, learners make a helium balloon "flink"--neither float away nor sink to the ground. Use this activity to introduce physics concepts related to gravity, density, and weight.
Ice Cream Shake
Source Institutions
In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.
Electric Gelatin
Source Institutions
In this activity, learners explore static electricity and electrical charges while experimenting with an inflated balloon, unflavored gelatin powder, and a wool sweater.
