Good News: We're on the Rise!
Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

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.

Moving Without Wheels
In a class demonstration, learners observe a simple water cycle model to better understand its role in pollutant transport.

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.

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

Build a Lung
Source Institutions
Most of the time, we don't have to think about breathing. In fact, you're probably breathing right now without thinking about it!

Hot Stuff!: Creating and Testing for Carbon Dioxide
In this demonstration, learners observe vinegar and baking soda reacting to form carbon dioxide (CO2) gas.

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 #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.

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

Engineer an Octopus Suction Pad
Source Institutions
In this engineering design challenge, learners build an octopus-inspired suction pad that can grab an object and hold it tightly in the air.

Photosynthesis and Transpiration
Source Institutions
In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

Seed Dispersal
Source Institutions
In this outdoor activity and bingo-like game, learners explore why and how seeds spread far from the plants that produce them.

Lichen Looking
Source Institutions
In this outdoor activity, learners search for lichen, a combination of a fungus and an alga living together. Lichen grow where most other plants cannot, on rocks, the trunks of trees, logs and sand.
Pollution and Lung Health
Source Institutions
Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

Fungus Among Us
Source Institutions
In this environmental health activity, learners grow and observe bread mold and other kinds of common fungi over the course of 3-7 days.
Fossil Fuels: Facing the Issues
Source Institutions
Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

Decomposition Column
Source Institutions
In this activity, learners turn empty 2-liter bottles into a see-through compost container.
