The best of intentions can have negative results. Learners explore the history of the use of chlorofluorocarbons and their effects on the ozone layer. They discover how widely the compound was used because of its unique chemical...

Part three in the series of seven has pupils discussing the different greenhouses gases, learning about the carbon cycle, and then watching a short video about the carbon cycle. Based on their knowledge, individuals complete a greenhouse...

If you need a comprehensive review of the development of Earth's atmosphere through the ages, then this is for you! The presentation starts with a introduction to theories of planet formation and initial distribution of isotopes in the...

Introduce your class to one of chemistry's functional groups, haloalkanes. A list of several functional groups is shown, but then viewers are taught to identify and name haloalkanes. Examples of these compounds are given and the problems...

In this organic compounds activity, learners read about the development of chlorofluorocarbons and the breakdown of this compound in the atmosphere. Students complete 2 short answer questions.

Young scholars engage in the study of household cleaning products, how to read the labels and how to use them safely and also how to properly dispose of the containers when they are empty. They read the labels and determine if the...

Learners use an interactive online mass balance model to observe levels of chlorofluorocarbons over the past few years. Students evaluate the influence protocol emissions will have on the future levels of CFCs.

Pupils explore the causes and effects of the Earth's ozone holes through discussion and an interactive simulation. Using gumdrops and toothpicks, they conduct a large-group, interactive ozone depletion model.

Students identify that the atmosphere traps heat and makes the surface of the Earth warm enough for life and recognize that air pollution can cause a rise in temperature and ecological decline. They name human activities that can cause...
