In this outdoor activity, learners investigate the relationship between the slope of a trail and soil erosion.

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

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.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

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 make a solar oven. Learners witness the awesome power of the sun to make a yummy treat--a chocolate chip cookie!

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

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

This is an activity (located on page 3 of the PDF under Nanosilver Activity) about diffusion of small molecules across cell membranes.

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 activity, learners build one or more edible coral polyps and place them together to form a colony.

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.

In this activity, learners receive a labeled plastic film canister containing a material representing a pollutant (i.e. pencil shavings = a beaver's wood chips).

Learners will build and experiment with their own windmills made from simple household materials.

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 outdoor activity, learners simulate an oil spill using popcorn (both oil and popcorn float on water), and estimate the spill's impact on the environment.
