Leaf Stomata as Bioindicators of Environmental Change

When life hands you lemons ... experiment on them! Green chemistry gurus compare extraction methods for essential oils through a lab activity. Lab groups use traditional distillation and liquid carbon dioxide extraction...

Earth or environmental science pupils are assigned to be carbon sources or sinks. They ask yes-or-no questions to try to figure out which one they are. Then they discuss ways people can have positive effects on the changing climate by...

An interesting lesson takes pupils on a trip through the carbon cycle. A reading passage allows scholars to take notes and make choices about what happens to the carbon on its journey. This third lesson in a series of 21 discusses...

Meteorologists view an animated video by the Environmental Protection Agency to learn how the carbon cycle works, and then move into groups to analyze and graph actual data of the atmospheric carbon dioxide concentration from Hawaii's...

Young scientists show how carbon dioxide in the air affects plant growth. This math and science activity provides a good platform for learners to combine scientific knowledge with mathematical representation of data. A simple, yet...

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

In this colorful animation, our current problem with climate change is likened to a block-stacking game of Tetris. Greenhouse gases are increasing in the atmosphere at an increasing rate. Can we place them properly before it's too late?...

Watt is going on here? Middle schoolers are learning about energy use and carbon dioxide emissions! In the first part of this lesson, learners measure how much energy different appliances consume and calculate the amount per day. In...

After a lecture about how the first industrial revolution triggered the path to climate change, your environmental studies class discusses what the impacts are. In a culminating activity, they get into groups and identify countries on a...

Expectant earth scientists examine the bottom side of a leaf and learn the role of the stomata. They consider the gas exchange that occurs through these structures and relate how the climate is changing to its impact on food crops. This...
