In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

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

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

Learners create a small explosion by collecting hydrogen and oxygen gas together and squeezing them into a flame.

Demonstrate the Bernoulli Principle using simple materials on a small or large scale.

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.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

This demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and temperature inside

In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity, learners use chocolate to explore how the Sun transfers heat to the Earth through radiation.

In this quick activity, learners observe how wind creates ocean currents.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

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

In this quick activity (page 1 of PDF under SciGirls Activity: Kites), learners will witness firsthand the effects of Bernoulli’s Principle by capturing a ping pong ball in the stream of air created b

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

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.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).
