In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners explore how salt water freezes in comparison to fresh water.

How does a green roof, or roof covered by plants, affect the temperature of the inside and outside of a building? Learners design and build houses to find out the answer.

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

This activity uses LEGO® bricks to represent atoms bonding into molecules and crystals. The lesson plan is for a 2.5 hour workshop (or four 45-minute classes).

In this activity related to climate change, learners examine albedo and the ice albedo feedback effect as it relates to snow, ice, and the likely results of reduced snow and ice cover on global temper

In this design-based activity, learners explore environments, ecosystems, energy flow and organism interactions by creating a model biodome. Learners become engineers who create model ecosystems.

In this weather-related activity, learners make a portable cloud in a bottle.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

This is part 2 of the three-part "Crayon Rock Cycle" activity and must be done after part 1: Sedimentary Rocks. In this activity, learners explore how metamorphic rocks form.

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.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

This is part 3 of the three-part "Crayon Rock Cycle" activity. Before starting this section, learners must have completed part 1: sedimentary rock and part 2: metamorphic rocks.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

Learners observe two model atmospheres -- one with normal atmospheric composition and another with an elevated concentration of carbon dioxide.

This is part 1 of the three-part "Crayon Rock Cycle" activity. In this activity, learners explore how sedimentary rocks form.

In this activity, learners work in teams to investigate the composition of unseen materials using a variety of tools.

In this activity, learners make a miniature greenhouse or "terrarium" to explore the greenhouse effect.

In this activity, learners create a biosphere in a baggie.

This activity (on page 3 of the PDF under GPS: Cactus Activity) is a full inquiry investigation into how some desert birds keep their cool.
