Divide the class up into the number of biomes that you would like them to research. Have the students find information about each biome through the Internet and books in the school library. They must discover at least one plant that is unique to the biome to which they have been assigned. Ask the students to draw a diagram of that plant to present to the class, along with an explanation of why that plant grows in that particular biome.
Assign students a series of questions about the biomes and allow them to use The World's Biomes website to find the answers. Ask very specific questions such as "During which period did the first flowering plants appear" and "Which element is the largest part of the biosphere"? Require them to indicate the place on the website where they found the answer. Award a small prize, such as a no-homework pass, to the first student to complete the hunt.
Assign each student a particular biome, or divide the class up into groups for a cooperative project. The students must research the food web in that particular biome, both on the Internet and/or in books from the school library. They must include decomposers, primary feeders and so forth. Ask them to create a visual representation of the food web for their biome, and then present the information to the rest of the class.
Ask students to create travel brochures for different biomes. However, they should pick a specific example of a particular biome, and not write a travel brochure for tundras or taigas in general, for example. They must include information about how to get to the biome, how travelers should dress in the area, photographs of the location and most importantly, tourist attractions, restaurants and hotels in the region.
