Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

In this activity (page 1 of the PDF under SciGirls Activity: Rabbits), learners will visit a zoo, aquarium, or pet store to view a variety of fish.

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

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

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

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.

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 outdoor activity, learners use a "litter-critter" wheel to help them identify different animals they find living in a natural litter habitat.

In this activity, learners identify different plastics in a mystery bag. Learners discover that plastics are classified #1 through #7.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

In this activity, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

Have you noticed the plastic rings that are used to hold six-packs of soda? Those rings are great for carrying cans, but they're real trouble when they become trash that animals can get tangled in.

In this outdoor activity, learners explore how a surprising number of animals use human-made litter, such as cans and crumpled paper, to find food and shelter in their environment.

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

This activity encourages learners to focus on the natural environment of the Eastern Woodlands before the arrival of European settlers.
