Fourth grade's final rotation in the lab for the school year begins with research into the Earth's biomes. Students started with some note taking on BrainPop and identified the different biomes and the variations in climate and elevation that define them. Next, students formed teams, or elected to work alone, and were randomly assigned one of the biomes. They continued their research using BrainPop along with National Geographic resources and online encyclopedias to learn about the plants and animals that inhabit the biome they were assigned. In particular they were to find the adaptations that organisms in that biome use to survive. The information collected was organized into a table showing the name of the organism, the adaptation, and the role that adaptation plays in keeping the organism alive.
Up until this point, I did not tell students what they would actually be making in this unit because I did not want the product to influence their research. However, with the note taking portion of the project complete, it is time to outline their task. The challenge is to imagine an organism that lives in the biome they were assigned with a focus on giving it the adaptations it needs to survive there. Students planned their organism in their journals complete with labeled sketches highlighting the adaptations. With their plans complete, students used the STEM Lab standard materials of cardboard and paper scraps to build a model of their imagined organism.
Students spent several days working on this part. One of the things I have been focusing on getting the children to understand when they are making things is that just because we are building with trash, it doesn't have to look trashy. It is sort of like a neatness counts idea, but really it is more about getting them to slow down and take their time. Their project being done well is more important than it being done fast.The final step was for the teams to make a small model of their biome to to display their model in. They also filled out a display card to accompany their work. I invited one of the first grade classes to the lab to visit the imaginary menagerie and the fourth graders had to discuss their projects for a younger audience.
This was a new project for the lab and I am generally pleased with how it has gone so far. However, for future iterations, I am planning on direction students to include at least one adaptation from different categories into their imagined organism. That is, an adaptation for dealing with the climate, an adaptation for getting food, and adaptation for defending itself, and so on. As it was, many of the projects so far have focused on adaptations for doing just one of those things and I want them to think about adaptations helping organisms do all of things they need to survive.
