Our grade 4/5 class has been studying biomes and we used this 3-D diorama idea to create mini biomes. 
The students used a variety of materials, including beads, Plasticine and lots of paper to create their biomes. Before we started this project, we did a lot of research on the features and inhabitants of each biome. Some of the biomes included:
Marine,
Rainforest, 
and Arctic.
The students were thrilled with their work and enjoyed the project.
