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

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.

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.

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 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 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.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi

Learners take a field trip along a local body of water and conduct a visual survey to discover information about local land use and water quality.

In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.

In this outdoor activity, learners plan a simple foot path and create an environmental impact study of the natural area where the path would be.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.
