Lungometer
Source Institutions
In this environmental health activity, learners investigate their own vital lung capacities.

Hot Cans and Cold Cans
Source Institutions
Learners apply their knowledge of heat transfer to design two cans - one that will retain heat and one that will cool down quickly.

How Greenhouse Gases Absorb Heat
Source Institutions
Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

Balloon Staging
Source Institutions
In this activity, learners simulate a multistage rocket launch using party balloons, fishing line, straws, and a plastic cup.

Lotus Leaf Effect
Source Institutions
This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

How the Rubber Meets the Road
Source Institutions
In this activity, learners explore how engineers design tire treads to increase safety and reliability.

Homemade Rube Goldberg Machine
Source Institutions
In this fun and, at times, hilarious force and motion activity, learners will use household objects to build a crazy contraption and see how far they can get a tennis ball to move.

Push It Out
Source Institutions
In this physics related activity which requires adult supervision, learners make their own powerful water rocket and, with it, explore Newton's Third Law of Motion.

Make a Mobile!
Source Institutions
In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

Mechanical Madness
Source Institutions
In this online Flash game, learners test their engineering know-how, moving a collection of mechanical parts onto a board to make complete a system of parts that will move a ball from start to finish.

Bobbing Eyeballs
Source Institutions
In this activity, learners use simple materials and basic tools to construct a special toy to explore pendulums. As the head of the toy bobs one way, the eyeballs bob the other way.

Cable Car
Source Institutions
In this activity, learners string a line across the room and build cable cars that can move from on end to the other.

Size Wheel
Source Institutions
In this fun sticker activity, learners will create a size wheel with images of objects of different size, from macroscopic scale (like an ant) to nanoscale (like DNA).

Hovercraft
Source Institutions
In this activity, learners build a hovercraft using a paper plate, cup, and simple motor.

Causes and Effects of Melting Ice
Source Institutions
In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

Build An Aqueduct
Source Institutions
In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

Heart of the Matter
Source Institutions
In this activity, learners explore the concept of valve operation and how engineers have adapted valves for use in mechanical heart valve design.

The Carbon Cycle Game
Source Institutions
In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

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.

How Do We Convert Electrical Energy into Mechanical Energy?
Source Institutions
In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.
