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.
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.
Plugged in to CO2
Source Institutions
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.
Hot Stuff!: Testing for Carbon Dioxide from Our Own Breath
Learners blow into balloons and collect their breath--carbon dioxide gas (CO2). They then blow the CO2 from the balloon into a solution of acid-base indicator.
A Merry-Go-Round for Dirty Air
Learners build a model of a pollution control device--a cyclone. A cyclone works by whirling the polluted air in a circle and accumulating particles on the edges of the container.
Hazardous Chemicals in Your Neighborhood
Source Institutions
In this environmental science lesson, learners will examine hazardous chemicals and their effects on human health and the environment.
Hot Stuff!: Carbon Dioxide Extinguishes a Flame
In this demonstration, learners observe vinegar and baking soda creating carbon dioxide (CO2) in a bottle. The gas is poured out of a bottle onto a candle flame, putting out the candle.
Hot Stuff!: Investigation #2
Learners test two jars containing hot water, one covered with plastic and one open, for changes in temperature.
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.
Cleaning Air with Balloons
Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.
The Search for Secret Agents
Learners tour their school or home looking for sources of indoor air pollutants (IAPs).
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.
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.
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.
