What impact do humans have on greenhouse gas emissions? What are the natural causes of these gasses? Thanks to the carbon cycle, carbon dioxide eats away at the earth's atmosphere with the intensified help of humans. Young scientists...

What better way to make predictions about future weather and climate patterns than with actual climate data from the past? Young climatologists analyze data from 400,000 to 10,000 years ago to determine if climate has changed over...

Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

When is the last time pupils did a happy dance in class? Scholars act out photosynthesis and dance excitedly in front of the class. The resource also comes with a worksheet for those waiting or who have already completed the...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Video talks about the carbon cycle and uses a computer as a metaphor to show how the cycle can be disrupted by climate change. [3:55] Includes a short quiz and a list of additional resources to explore.

Instructional module focusing on the carbon cycle. Discussion includes the biological and geological components of how carbon moves through the atmosphere, lithosphere, and hydrosphere. Site also includes an interactive practice quiz and...

Students will learn about how the Earth's carbon cycle works, as they examine the relationship between levels of carbon dioxide and water vapor in the atmosphere and the temperature of the ocean's surface. Includes online student...

By the end of this section, you will be able to state the expressions of the second law of thermodynamics; calculate the efficiency and carbon dioxide emission of a coal-fired electricity plant, using second law characteristics; and...

The simulation shows the relationship between the inputs and outputs in the chloroplasts of plant, that can help explain how they convert water and carbon dioxide to glucose and water with the help of energy absorbed from light.

An interactive lab simulation demonstrates the effects of increased carbon in the atmosphere and how that increase contributes to climate change. A data table for student records is available for download.
