Household Chemicals & the Environment

Working in groups of two, learners examine their own carbon footprints and energy consumption, then determine a plan to reduce their impacts on the environment. Although designed to be a final project for a chemistry class, the...

Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for confirmation....

To wrap up your year of general chemistry, have lab groups compete in a tot wire chemical vapor deposition (HWCVD) competition. With their foundation in chemical nomenclature, stoichiometry, and gas laws, each group completes several...

What effects do temperature and carbon dioxide levels have on the zooplankton of Antarctica? This concluding lesson in a short unit on climate change and the ocean helps environmental scientists answer these questions. After learning...

Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

Four lessons can be found in this chemistry resource. A pretest is provided, and then young chemists explore the law of conservation of mass in chemical reactions. Then they learn about the laws of definite and multiple proportions. In...

Clean up the environment with a lesson that focuses on replacing hazardous cleaning supplies with green, environmentally-friendly products. Using a dirty patch of surface as a control area, kids clean other parts of various surfaces...

This is a classic chemical reaction to use in your science class. Starch and iodine mix to cause a color change. Discuss with aspiring chemists the chemical and physical changes that occur as you demonstrate.

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

Students examine the effect of hazardous chemicals on humans. They discover how the chemicals are cleaned up and the facilities in their neighborhood. They identify federal and local agencies that oversee environmental hazards
