The document assigns students to groups to research and present on different biomes. It divides the class into two sections, A and B, with five groups in each section. Each group is assigned a biome to study such as hot zones, temperate zones, cold zones, biomes in Spain, and humans and the environment. The groups must prepare presentations on their assigned biome to present on scheduled dates using information from their textbooks. They are instructed to look up unknown words, make good use of preparation time, and be creative in their presentations by including images or videos. At the end of all the presentations, there will be an exam on the unit.
