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.

In this activity, learners make cool boxes out of old (or new) greeting cards or postcards.

In this activity on page 12 of the PDF (Rethinking the 3 R’s: It’s Easy to be Green), learners examine how recyclable materials are separated by various properties at recycling centers.

In this activity (page 4), learners work in groups to plan and build large structures using recyclable materials they have brought from home.

Learners will follow a specific process to make their own paper using scrap paper, newspaper, or junk mail.

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.

In this crafty chemistry activity (on page 2 of the PDF), learners make their own paper from used paper they may have otherwise thrown away.

In this outdoor activity, learners go "can fishing" and discover the kinds of aquatic organisms that live in and on submerged cans.

Learners shred used paper, add water, and blend it into pulp. They then strain and roll the pulp out to make new paper.
