Students discuss caves. In this science lesson, students experiment with how dissolution, a chemical weathering process, leads to the formation of caves. Once the cave is finsihed students draw a picture or describe in writing what it...

Students examine the evidence that scientists have used to support the existence of global warming and the greenhouse effect. How the concepts have been developed and evaluated form the focus of this lesson.

Seventh graders identify how much carbon is held by the world's forests. For this forestry lesson, 7th graders study the carbon cycle and discuss what role humans have had on climate change. Students write a one page paper on how...

Seventh graders learn how trees help nature recycle.  In this carbon cycle lesson, 7th graders view a picture of a giant redwood tree, complete a Think, Pair, Share activity, view and discuss a poster about how nature recycles,...

Ninth graders investigate biological systems. They summarize relationships between systems. Students determine how systems relate within the biosphere. They analyze the carbon cycle.

Climate models mathematically represent the interactions of the atmosphere, oceans, land, sun, surface, and ice. Part two in the series of four lessons looks at the role greenhouse gases play in keeping Earth warm and has participants...

Using a colorful infographic handout and a guide sheet, hold a class discussion about how a bathtub can serve as a model for the greenhouse effect created by Earth's atmosphere. Participants will understand that as energy or matter is...

In this English worksheet, students read "New Machine Sucks CO2 from the Air," and then respond to 1 essay, 47 fill in the blank, 7 short answer, 20 matching, and 8 true or false questions about the selection.

Finally, a photosynthesis activity that outshines the rest! Young biologists perform an experiment that allows them to observe photosynthesis through the production of oxygen. The lesson, part of the K20 series, also includes a study of...

Eighth graders research the Greenhouse Effect on the Internet. They use a variety of sources and take notes on the topic. They use ClarisWorks to type a report, use spellcheck, proof and edit. They can create a class bulletin board.

A somewhat amusing assignment, this instructional activity lists statements that an ancient organism may have made and asks learners to determine what geologic era that each may have lived in. It uses witty word puzzles and...

Young scholars, using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, observe and record the role of light in photosynthesis. They consider plant production of carbon dioxide and the use of live materials in biological...

High schoolers investigate the quality of water using a variety of methods. They use a pH probe to measure the pH and study the effect of dissolved CO2 in the water. Students also observe the effect of the pH upon the dissolving of H2SO4...

Students explore geologic sequestration as a technique used to reduce carbon dioxide in the atmosphere. They use chemistry to stimulate oil mining. Students conduct an experiment to learn about geo carbon sequestration.

Young scholars examine carbon dioxide and determine the impact of greenhouse gases on the earths spheres.  In this pollution lesson students complete a lab activity to see the impact of gases on the environment, 

Students determine some practical implications of the discovery of liquid carbon dioxide in deep-ocean ecosystems. They interpret phase diagrams and explain the meaning of "critical point" and "triple point."

Students work in groups to research biomass using the International Energy Agency's website. Students use evidence from the web search to assess biomass energy potential in Pennsylvania as part of a classroom "Alternative Energy...

Seventh graders explore how exercise affects carbon dioxide levels in exhaled air.

Students use Internet research to become familiar with the environmental and health effects of the six criteria pollutants identified by the U.S. EPA, along with the greenhouse effect and carbon dioxide.

Alone, or as part of the intended unit on chemical reactions, this activity allows learners to experience an exothermic reaction. Here, learners add calcium chloride to a baking soda solution and watch the temperature rise! They will...

Here's a five-star lesson plan in which inquisitors conduct sophisticated experimentation with cellular respiration in plant seeds. Placing seeds in a closed system they measure the amount carbon dioxide produced and relate it to...

Real world chemical reactions are used as examples for teaching stoichiometry. Viewers work through air bag inflation, fat conversion to water in a camel, rocket fuel combustion, and carbon dioxide removal in spacecraft. Make...

One friend explains to another that plants combine water and carbon dioxide with the energy of the sun to produce sugar and oxygen. She mentions the roles of the roots, chloroplasts, and stomata in an engaging video that reviews how...

During a three-part lesson, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which is...
