Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.

Learners construct an electricity-generating wind turbine out of a plastic bottle.

In this activity, learners will explore the ways natural materials can produce sounds. Appropriate for any age, learners can make individual music or create a symphony with others.

Learners build a wind turbine and test it to see how much energy is created.

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

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

In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).

The objective of this inquiry-based lesson is for learners to gain an understanding of how increasing ocean acidity can affect the calcification of marine organisms.

This board game teaches learners about energy decision making. Players select cards that determine the transportation and home design that will influence their expenses as they play.

In this group activity, learners consider environmental conditions—temperature, presence of water, atmosphere, sunlight, and chemical composition—on planets and moons in our solar system to determine

In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.
