In this activity (page 19 of the PDF) learners will create a soda bottle bioreactor by exploring the science of composting, comparing variables such as reactor design, moisture content, and nutrient r

In this engineering activity, learners investigate the differences between the strength of bridges made from flat and round building materials.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

In this environmental education demonstration (page 6 of the PDF), learners will see a tangible representation of the scarcity of soil resources on earth.

This is an activity about rockets. Learners will explore how rockets leave Earth's orbit and what it takes to make a launch successful.

In this physics activity, learners build their own rockets out of film canisters and construction paper.

This is a web activity about simple machines. Learners will explore a lawn mower and identify six different simple machines which work together to help make our lives easier.

In this activity, learners design a bicycle helmet. Participants will explore the design of bicycle helmets to gain an appreciation for the role that helmet layers play protecting the head.

In this geology and engineering activity (page 7 of the PDF), learners build an earthquake simulator, then use it to test various building designs, exploring different materials, shapes, and design op

In this engineering activity, learners test the stability of towers they build out of cups, discovering that structures with more mass in the base are more stable.

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.

In this physics activity, learners will build their own parachutes out of tissue paper. They will explore the effects of weight, height, and design on the parachutes' speed and stability.

In this activity (page 10 of the PDF) learners will explore the historical progression of siege weapons to gain an understanding of how the addition and modification of parts can change the efficiency

In this activity, learners explore why frost forms. They create their own frost using a solution of ice water and salt in a glass.

In this physics activity, learners will investigate the strength of egg shells.

In this activity, learners construct a rocket powered by the pressure generated from an effervescing antacid tablet reacting with water, and build a launch pad for their rocket.

In this ecology activity (page 8 of the PDF), learners explore how to filter contaminated water using a variety of materials.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

In this physics activity (page 8-9 of the PDF), learners will explore wind energy. They will build their own windmill and see how energy from wind can be converted into a useable form.
