Learners test two jars containing soil, 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 test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.

In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.

As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

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.

Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

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

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien
