In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

In this activity, learners explore how wind energy can be generated on both a large and small scale.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

This lab activity is about toxic substances like pesticides and their effects on biological systems. The activity starts with an introduction of how birds sequester calcium to make an egg.

In this activity, learners explore the function and engineering of dams and how dams have many uses and solve many problems in the world.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.

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

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

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.

In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.

In this outdoor, night-time activity, learners discover how to spot eye-shine (reflection of light from an animal's eyes) by using a flashlight to play a simulation game.

In this activity, learners explore how engineers design devices that can detect the presence of pollutants in the air.

In this activity, learners take on the role of a carbon atom and record which reservoirs in the carbon cycle they visit.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners explore how watermills have helped harness energy from water through the ages.

Using simple, inexpensive items, learners build and test submarine models.

In this outdoor activity, learners search for the warmest and coolest, windiest and calmest, wettest and driest, and brightest and darkest spots in an area.

In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.
