Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

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

In this activity on page 24, learners perform experiments to examine whether or not trash can float, blow around, or wash away.

To convey the concept of how animals adapt to survive, this game asks learners to imagine what adaptations a given animal would need to live in a certain environment—including environments where such

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

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.

In this activity, learners explore the web of connections among living and non-living things.

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

This is an activity about turbidity, or the amount of sediment suspended in water.

Learners test two jars of ice water, one covered and one open, for changes in temperature. After placing the jars in the sun, learners discover that the covered jar cools down more slowly.

Learners see convection currents in action in this highly visual demonstration. Sealed bags of colored hot or cold water are immersed in tanks of water.

Learners develop an understanding of air pressure in two different activities.

Learners build devices from rubber bands to test for invisible air pollutants.

In this outdoor activity, learners cut through and investigate rotten logs and then make log-profile puzzles for each other.

In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

In this outdoor fall activity, learners find out what living in or under a layer of leaves is like.

In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this activity, learners take an indoor nature walk and discover various objects that have been brought in from the outdoor environment.
