In this online game, learners must purchase power plants for their city.

In this activity, learners explore how civil engineers solved the challenge of moving water via irrigation.

In this activity, learners explore the concept of how brakes can stop or slow mechanical motion.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners explore the parts of a circuit by modeling, as a group, a “human” circuit.

In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.

In this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates.

Build a pinwheel that works without wind! This activity contains steps on how to build a parachuting pinwheel out of paper, a film canister, and some brads.

In this design challenge activity, learners invent a way to send a Ping-Pong ball flying high enough to catch it - like football with a twist!

In this design challenge activity, learners build a machine that kicks a Ping-Pong ball into a cup lying on its side 12 inches away.

In this physics activity (page nine of the pdf), learners use balloons to explore how a rocket works. It is suggested they also work to see how they can alter the velocity of the rocket.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

In this fun physics activity (page 9 of the pdf), learners take part in a paper airplane design challenge.

Learners build a wind turbine and test it to see how much energy is created.

In this design challenge activity, learners build a car that can travel at least four feet using rubber band power and use the design process to debug problems.

This activity is on page 3 (continued on page 2) of the pdf, part of the Simple Machines Discovery Box. In this fun activity, learners "create" a complex machine by simulating the parts in action.

Learners compare the properties of two balls that appear identical. One ball bounces, while the other ball "thuds." The “bounce” ball is made of the polymer polybutadiene (-C4H4-).

In this activity, learners discover if carbon dioxide has an effect on temperature.

Construct a simple battery that's able to power a small light or motor out of foil, salt water, and charcoal. A helpful video, produced by the Exploratorium, guides you along on this activity.
