Next, we had a discussion on climate change. We went over some background information, some causes and effects, future predictions and why there are some who deny climate change is occurring.
Then, we performed an experiment that simulated the effects of greenhouse gases. We filled plastic bottles each with air, carbon dioxide, and moist air. We placed the bottles under lamps and tested how the different gases contributed to the change in temperature in the bottles!
Lastly, we had a "Big Picture" discussion about the experiment. We discussed positive and negative feedback loops and why they are important when talking about greenhouse gases.
