Action-Reaction Rocket!
Learners construct a rocket from a balloon propelled along a guide string.
Blow-and-Go Parachute
Learners make a skydiver and parachute contraption and launch it. They see that the drag created by air resistance slows the descent of skydivers as they travel back to Earth.
Uncanny Motion
Source Institutions
In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.
Under Pressure
Source Institutions
In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.
Building Bridges
Source Institutions
In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.
Shake Table
Source Institutions
This activity guide includes instructions on how to build a "Shake Table" by mounting an eccentric mass (off center) on the shaft of a small dc motor.
Newton Car
Source Institutions
In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.
Rubber Band Racer
Source Institutions
In this activity, learners construct speedy vehicles made out of paper plates and powered by twisted rubber bands.
Strong Bones, Weak Bones
Source Institutions
Most people will break a bone in their body at some point in their life, but how much force does it take to break one?
Speedboat
Source Institutions
In this activity, learners build a speedboat using paint paddles, a propeller, and film canister. Learners attach a simple circuit and motor to the boat to power the propellers.
Chain Reaction II
Source Institutions
In this hands-on activity, learners use an assortment of (mainly household) items to complete Rube Goldberg-type challenges.
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.
Anti-Gravity Chamber
Source Institutions
In this activity, learners will use magnets and household items to create a structure that allows paperclips to appear like they are floating.
Egg Bungee
Source Institutions
Learners attach an egg to a rubber-band bungee cord and drop the egg.
Trebuchet Toss
Source Institutions
In this activity, learners explore trebuchet design. Teams of learners construct trebuchets from everyday materials.
Water Rocket Launch
Source Institutions
In this activity, learners explore rocketry and the principals of space flight.
Catapult
Source Institutions
In this activity, learners build mini catapults using paint paddles and a spoon. Use this activity to introduce learners to forces and projectile motion.
The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.
