In this activity, learners make a small batch of biodiesel that will work in any diesel engine. Learners use an old juice bottle as a "reactor" vessel to chemically process vegetable oil into fuel.

In this activity, learners explore how the process of folding has impacts on engineering and is evident in nature.

Make a model city happier with LEDs, circuits, motors, and batteries! Groups can think, discuss, design, and build what would make a community happy. Kids can work as part of a team or on their own.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

In this activity, learners investigate passive solar building design with a focus solely on heating.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity, learners explore electronic communication, the Morse Code system, and advances all the way through text messaging. Learners build a simple circuit, send messages to one another.

In this activity, learners explore the concept of friction and how ball bearings reduce friction.

In this activity, learners explore the many uses of periscopes and how this simple device was designed and is used in many applications.

In this activity, learners incorporate a simple switch into a battery/bulb circuit. Learners will use their knowledge of circuits to design and make their own switches using common materials.

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

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners explore computer programming and the impact of computers on society. Learners build and test a program to turn a light on and off using an Arduino board.

Build and test a scale model of a rainforest canopy walkway.

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners simulate the process of DNA fingerprinting by using electricity to separate colored dyes.
