In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

This activity has three story puzzles learners can solve to learn about life in the Arctic.

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.

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 explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

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

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

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

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

In this activity, learners gain a better understanding of how household/school waste breaks down in a landfill. Learners collect trash and then create miniature landfills in 2-liter bottles.
