In this activity, learners cut out a fish and then "paint" it using universal indicator and acids and bases.

In this activity (on pages 18-29) learners explore the impact of the March 24, 1989 oil spill in Alaska caused by the Exxon Valdez tanker.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this group activity, learners act out key stages of the "ocean carbon cycle" (also known as the "carbonate buffer system") through motions, rearranging blocks and team tasks.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

In this activity on page 7 of the PDF, learners investigate the solubility of gas in water at different temperatures. This experiment will help learners determine if temperature affects solubility.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

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

In this group activity, learners will explore the characteristics, functions and uniqueness of the mangrove tree.

In the wild, small crustaceans known as brine shrimp live in marine habitats such as saltwater lakes.

In this activity, learners will discover how the thin layers of amphibians' skin allow water and other chemicals to pass through it.

In this activity, learners explore the factors that tend to resist changes in pH of the ocean and why the ocean is becoming more acidic.

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
