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

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

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.
