Historical Climate Cycles
Ice core samples give scientists access to climates of old—those from more than 800,000 years ago. Through an analysis of various temperature graphs from ice cores, tree rings, and weather stations, scholars compare historical climates...

Acid Rain
Simulated acid rain, a dilute sulfuric acid solution, needs to be prepared for this demonstration. After a condensed lecture on acid rain, you will apply the solution to a sample of granite and a sample of limestone. Your young...

Urban Ecosystems 4: Metabolism of Urban Ecosystems
Students discover that material and energy uses by a city come from outside the city boundaries. They realize that the pathway of these material is linear instead of cyclical as they are in natural ecosystems.

Urban Ecosystems 2: Why Are There Cities? A Historical Perspective
Students investigate the importance of food surpluses to the historical development of urban ecosystems.

CO2 and You
Students study the scientific evidence about carbon dioxide emissions. They learn to calculate the amount of energy used by different appliances. They complete a worksheet which analyzes the amount of energy that their home uses.

Linkages Between Surface Temperature and Tropospheric Ozone
High schoolers use data microsets of mean near-surface air temperature and tropospheric ozone residual averages to infer patterns. Students analyze changes in tropospheric ozone and then hypothesize about the consequences of these changes.

Sources of Energy
Fifth graders take a close look at how energy changes from one form to another within their surroundings. They also study the ten different sources of energy and determine which are renewable and which are non-renewable. This seven-page...

Renewable vs. Non-Renewable Resources
Fifth graders are introduced to the important topic of renewable, and non-renewable, resources. They are expected to be able to correctly categorize different types of resources as renewable or non-renewable. Another emphasis of this...

Acid Rain Effects
Get out the goggles and 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. Young chemists observe and describe the harmful...

The Chemistry of Refining Crude Oil
Consider our energy sources: wood, coal, oil, uranium. Learners compare the pollution to energy produced for each. They practice fractional distillation of an alcohol/water mixture to simulate the process of refining crude oil....

What is pH and Why is It Important?
Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

The Greenhouse Effect
Why does it get so hot inside of our cars in the summertime? The greenhouse effect! Lab groups experiment to see what happens to an ice cube enclosed in a jar and placed in sunlight as compared to an ice cube outside of the jar. They...

The Influence of Human Activity on the Environment
The surge in human population in the last 2,000 years, due in large part to better health care, has brought a surge in the demand for resources and in pollution. The graphics, photographs, and real-life examples in a thought-provoking...

Green Chemistry
The principles of pollution control on a molecular level are summarised here. The reasoning and study behind the principles are described, and your class will undestand how some techniques are developed to be more efficient.
