Salt, Soil and Seeds
Source Institutions
Discover how the salt in soil affects plant growth with a few seeds, some cotton, and salt. In this hands-on activity, you will plant seeds in 2 different kinds of soil, containing more or less salt.

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.

How Might Elevated CO2 Affect Plants
Source Institutions
In this activity, learners conduct an experiment to investigate the effect of elevated levels on CO2 on plant growth.

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.

Super Soil
Source Institutions
In this outdoor activity, learners make their own organic-rich soil. Depending on where this activity is done, learners will probably discover that their local soil is low in organic matter.

Moisture Makers
Source Institutions
In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

Composting
Source Institutions
In this environmental science activity, learners research what is essential for plant life and the necessary components of soil to support plants.

The Carbon Cycle and its Role in Climate Change: Activity 2
Source Institutions
In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

Estuaries
Source Institutions
An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

Water Treatment
Source Institutions
Water treatment on a large scale enables the supply of clean drinking water to communities.
Mercury in the Environment
Source Institutions
In this environmental science lesson, learners will examine the dangers of mercury and how humans contribute to growing mercury emissions on Earth.

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.

Water "Digs" It!
Source Institutions
In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

Small Habitats
Source Institutions
In this activity, learners build a model of a self-sustaining habitat (growing grass and beans from seeds).

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.

Environmental Chemistry
Source Institutions
In this activity with several mini experiments, learners explore the chemistry that helps scientists learn about the environment and how they can help save it.

Fragile Waters
Source Institutions
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.

Water Quality and pH Levels in Aquatic Ecosystems
Source Institutions
In this fun and in depth hands-on experiment, learners test various liquid samples (distilled water, lemon juice, vinegar, and baking soda mixed with water) to determine their pH levels and identify e

The Carbon Cycle: Carbon Tracker
Source Institutions
In this activity, learners play NOAA's Carbon Tracker game and discover ways to keep track of carbon dioxide and other greenhouse gases in the world.
What Does Life Need to Live?
Source Institutions
In this astrobiology activity (on page 11 of the PDF), learners consider what organisms need in order to live (water, nutrients, and energy).
