About Teaching Climate Literacy
2d 
2dThe abundance of greenhouse gases in the atmosphere is controlled by biogeochemical cycles that continually move these components between their ocean, land, life, and atmosphere reservoirs. The abundance of carbon in the atmosphere is reduced through seafloor accumulation of marine sediments and accumulation of plant biomass and is increased through deforestation and the burning of fossil fuels as well as through other processes.

Energy Literacy
Environmental quality is impacted by energy choices.
7.3 Environmental quality.
The quality of life of individuals and societies is affected by energy choices.
Energy affects quality of life .
Humans transfer and transform energy from the environment into forms useful for human endeavors.
4.1 Humans transfer and transform energy.
Different sources of energy and the different ways energy can be transformed, transported and stored each have different benefits and drawbacks.
4.7 Different sources of energy have different benefits and drawbacks.
Greenhouse gases affect energy flow through the Earth system.
2.6 Greenhouse gases affect energy flow.
Physical processes on Earth are the result of energy flow through the Earth system.

Benchmarks for Science Literacy

If a system in equilibrium is disturbed, it may return to a very similar state of equilibrium, or it may undergo a radical change until the system achieves a new state of equilibrium with very different conditions, or it may fail to achieve any type of equilibrium.

Technical Details
Teaching Tips
- Educator should explore the entire 'New to the Site' and 'For Teachers' sections of the activity and do a run-through of the tool before students use it.
- Younger students may require a more guided-inquiry approach (step-by-step worksheet).
- This could be a self-guided investigation for students or utilized as a class investigation. Educators could use the interactive then jump into further investigations based on those scenarios by using the other activities in the teacher section.
About the Science
- An interactive model on carbon-temperature relationships from NASA's Challenger Center. The model sets up an interface in which users select a scenario (such as deforestation, volcanoes, hurricanes) and change the inputs to and outputs of the system. As users change variables, the results are graphically represented, demonstrating how selections affect the whole system.
- Comments from expert scientist: This activity is quite interesting to be applied in the classroom. Students can get a clear idea about the possible sensitivities of sitema climate. The physics involved behind the calculations is not shown, or at least some references or supplementary materials could be indicated.
About the Pedagogy
- A very clear and concise set of teacher materials. Well-organized and well-thought-out resource with supporting materials and well-written directions to use the interactive.
- This model is a great way to have students research the shifting balance of Earth's system. Scenarios allow students to select and investigate the changes first hand while visually seeing the changes represented on a graph.
- Option to have students print out their results and add their own observations, after they've made their selections.
- Website http://earth4u.challenger.org/ offers educators support for implementing additional lessons based on carbon and climate change.
- Students need to be encouraged to read through instructions carefully before starting.
- This resource engages students in using scientific data.
