The document provides information about global warming and the greenhouse effect through a series of online activities and questions. Learners are instructed to visit several websites to learn about the greenhouse effect, greenhouse gases, evidence of climate change, and impacts of global warming. They are asked to fill out a chart on greenhouse gases, summarize climate influences, predict future climate impacts, and list ways individuals can reduce global warming. The goal is for learners to understand the science behind global warming and climate change in order to create an informative poster.
