In this activity, learners investigate passive solar building design with a focus solely on heating.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this engineering activity, learners will get acquainted with the basics of wind energy and power production by fabricating and testing various blade designs for table-top windmills constructed from

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

Agriculturalists have long considered mushroom growing a challenge, largely because you need a piece of benchtop equipment known as a laminar flow hood.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

In this puzzle, learners investigate the decisions involved in linking a network between houses in a muddy city.

Visitors mix water and sodium bicarbonate (baking soda) in a large flask. They then add citric acid to the mixture and stopper the flask. The resulting reaction creates carbon dioxide gas.

Visitors separate a mixture of pebbles, salt crystals, and wood shavings by adding water and pouring the mixture through a strainer.

In this activity, learners experience some of the challenges of "tele-operating" a robotic vehicle on another planet when they design and execute a series of commands to guide a human "rover" through

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

In this data analysis and environmental science activity, learners evaluate the feasibility of wave energy as a practical alternative energy source using ocean observing system (OOS) buoys.

In this activity, learners create a star show and discover how they can prevent light pollution. Using simple materials, learners first design constellation boxes.

Things that are different sizes and stiffness vibrate differently, and in this Exploratorium Science Snack, you'll see how rings of various diameters react to vibration and external forces.

This is a demonstration about how nature inspires nanotechnology. It is easily adapted into a hands-on activity for an individual or groups.

Visitors use heat to shrink samples of polystyrene. They compare samples from containers that were shaped in different ways during manufacturing.

Visitors incrementally increase the amount of iodate in three different test tubes containing the same amount of a starch solution.

In this activity, learners use molecular model kits to construct familiar molecules like lactose, caffeine, and Aspirin.

In this activity, learners explore the engineering and principles behind working elevators.

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.
