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.

In this up-cycling activity, learners recycle plastic bags and repurpose them into useful wallets.

Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

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

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

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.

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).

In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

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

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.

Use the Zoo Calendar (page 1 of PDF) to involve learners in interdisciplinary, whole language, and writing activities about ecological concepts.

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

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.

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