Hot Stuff!: Testing Ice
In this demonstration, learners compare and contrast regular water ice to dry ice (frozen carbon dioxide). Both samples are placed in a solution of acid-base indicator.

Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.

A Degrading Experience
Source Institutions
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.

Building A Storm Drain
Source Institutions
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.

Low-Tech Water Filter for High-Impact Clean
Source Institutions
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.

Battling for Oxygen
Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Let's Bag It
Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.

Hot Stuff!: Investigation #3
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.

What's Hiding in the Air?: Rubber Band Air Test
Learners build devices from rubber bands to test for invisible air pollutants.

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

The Search for Secret Agents
Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

The Effects of Acid Rain
Source Institutions
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.

There’s Oil in My Eggs
Source Institutions
In this activity, learners investigate the impact of oil pollution on the environment and wildlife. Learners use hard-boiled eggs and feathers to understand the damage that oil spills can cause.

Oil Spill Solutions
Source Institutions
In this activity, learners explore how environmental engineers might approach solving the problem of an oil spill.

For Your Eyes Only
Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

The Dead Zone: A Marine Horror Story
Source Institutions
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

Pollution Diffusion
Source Institutions
Learners design their own experiment to investigate how pollution diffuses through ground material.

What Trickles Down?
Source Institutions
Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

The Carbon Cycle and its Role in Climate Change: Activity 3
Source Institutions
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
