Cleaning with Dirt
Learners build a filter from old soda bottles and dirt. They create polluted water, and pour it through their filter to clean it.
In this activity related to indoor air pollution, learners build take-home dust catchers with wax paper and petroleum jelly.
Hot Stuff!: Investigation #4
Learners test two jars containing soil, 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.
Acid (and Base) Rainbows
Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.
Hot Stuff!: Investigation #1
Learners test two jars, one containing plain air and one containing carbon dioxide gas, to see their reactions to temperature changes.
Chemical Footprint—Family ActivityAdd to list Details
In this multi-part activity learners examine non-point water pollution.
Mercury in the Environment
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.
Straining Out the Dirt
Learners take on the role of environmental engineers as they design water filters.
Plugged in to CO2
In this activity, learners investigate various appliances and electronics, discovering how much energy each uses and how much carbon dioxide (CO2) is released to produce that energy.
Acid Rain Effects
Learners conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
What's Hiding in the Air?: Acid Rain Activity
As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.
Positive Planning Adds UpAdd to list Details
In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.
The Carbon Cycle and its Role in Climate Change: Activity 3Add to list Details
In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.
Pollution and Lung Health
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.
What Trickles Down?
Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.
Do Cities Affect the Weather?
In this activity, learners explore clouds and how they form.
In this activity, learners explore the concept of permeability to better understand why amphibians are extremely sensitive to pollution.
A Scientific CleanupAdd to list Details
This is a comprehensive lesson plan on page 85 for a group cleanup trip to a local beach, lake or stream. Learners keep track of the types and amounts of trash picked up and analyze this information.
All Tangled UpAdd to list Details
In this activity on page 60, learners examine and simulate wildlife entanglement by experiencing what it might be like to be a marine animal trapped in debris.
Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.
