Learners construct an electricity-generating wind turbine out of a plastic bottle.

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 explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.

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 build a solar oven from a cardboard pizza box, aluminum foil and plastic. Learners can use their oven to cook S'mores or other food in the sun.

In this activity, learners explore the engineering behind seismographs and how technology has improved accurate recording of earthquakes.

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

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this cooperative learning activity, learners visit ten stations and are challenged to think critically about various conservation questions and issues.

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

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

This fun and simple hands-on astronomy activity lets learners explore what happens when a star explodes.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

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

In this activity, learners discover how solar energy can be used to heat water.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

In this activity, learners explore rocketry and the principals of space flight.

Learners follow directions to construct a solar oven that really cooks! The solar oven uses aluminum foil to reflect sunlight into a cooking chamber, which is painted black.
