In this multi-part activity learners examine non-point water pollution.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

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 how environmental engineers might approach solving the problem of an oil spill.

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

In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

In this environmental science activity (page 4 of the PDF), learners use vinegar and chalk to observe the effect of acid rain on various building materials and plant life.

In this design challenge, learners design a storm drain cover that catches litter to protect waterways to learn about how local actions can have system-level effects.
