This document provides instructions for a presentation on the greenhouse effect. Students are asked to answer questions about fossil fuels, greenhouse gases, and the impacts of global warming before watching an animation. They then watch the animation and complete an activity worksheet. Finally, students discuss pictures related to the animation's content. The instructions are for a classroom activity where students will view an animation about the greenhouse effect and complete accompanying exercises to demonstrate their understanding.
