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.

In this activity, learners discover that sand is the major ingredient in glass.

In this activity, learners explore how engineering has impacted the development of bridges over time, including innovative designs and the challenge of creating bridges that become landmarks for a cit

In this activity about electricity, learners suspend pieces of tape from a straw to construct an electroscope, a device that detects an electrical charge.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

In this activity on page 13 of the PDF, use a special plastic card that has been painted with a chemical that changes color when it is in UV light.

In this activity on page 2 of the PDF, learners test different materials to find out which is the best insulator.

In this activity on page 7 of the PDF, learners experiment with the interesting designs that can be made by painting on plaster.

In this chemistry activity, learners use common chemicals to examine reactions that occur between two aqueous solutions.

Learners explore how the attractive forces between water molecules create surface tension and allow certain objects to float on the surface of water.

In this activity, learners build a special rolling can that returns back to you when you push it forward. Use this activity to demonstrate the transfer of energy between kinetic and potential energy.

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity, learners experiment with hydrogen peroxide, vinegar, yeast, and baking soda to produce hot and cold reactions. Use this activity to demonstrate exothermic and endothermic reactions.

Over the course of several days, learners explore the property of water that helps plants move water from roots to leaves or gives paper towels the capacity to soak up water.

In this chemistry activity, learners use common chemicals to produce carbon dioxide and observe its properties. This resource includes brief questions for learners to answer after the experiment.

In this activity, learners investigate the properties of plastic bags. Learners find out what happens when they slowly push a pencil through a plastic bag filled with water.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

In this activity, learners discover a trick to release the air out of a balloon without popping it.

In this activity, learners use a toaster to generate wind and compare the appliance's heat source to Jupiter's own hot interior. Learners discover that convection drives wind on Jupiter and on Earth.
