Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

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

Visitors add drops of copper sulfate solution onto a steel nail. They observe the nail change color from silver to brown as the copper plates onto the nail.

Visitors test solutions of water, sugar, salt, and hydrochloric acid and the solids salt and sugar. They clip leads from the hand generator to wires immersed in each substance.

Visitors prepare six solutions combining vinegar and ammonia that range incrementally from acid (all vinegar) to base (all ammonia).

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 observe what happens when they give a light source like a neon glow lamp a "Bronx Cheer." The lights appear to wiggle back and forth and flicker when learners blow air throu

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

In this activity, learners explore the invisible infrared radiation from an electric heater.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

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.

In this invention challenge activity, learners see how many objects they can grab with a homemade "bionic" arm.

In this activity, learners build a figure that moves and "comes to life" when they pull its string.

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

In this environmental activity (page 16 of the PDF), learners will calculate the amount of energy they save by recycling paper, plastic, glass, and aluminum materials over the span of a week.

This activity models the necessary balance of creating power and cleaning up its associated waste. Learners participate in a game where they attempt to move forward toward a goal.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

Visitors observe a bottle with a balloon attached around the mouth. The bottle contains a solution of yeast, sugar, and water.

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