Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

In this activity, learners explore how nanotechnology is being used to create new types of protective fabrics.

In this activity, learners make pykrete by freezing a mixture of water and a material like cotton wool, grass, hair, shredded paper, wood chips, or sawdust.

Learners make a simple battery out of "sandwiches" of aluminum foil, pennies, and a salt water-soaked paper towel.

In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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

Learners make their own paper. They start by shredding old newspaper, clean toilet paper, and clean paper towels.

In this activity, learners separate materials based on their special properties to mimic the way recyclables are sorted at recycling centers.

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

In this design challenge activity, learners design and build a solar hot water heater. Their goal is to create a heater that yields the highest temperature change.

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

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

This is written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

In this activity, kids make and play with Ooze before testing the material in an egg drop!

In this activity, learners build an electric two-paddle boat using paint paddles, plastic knives, and empty water bottles.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.
