Research the types of rabbits and the habitats in which they live. If possible, take a nature walk to collect leaves, petals, twigs, pebbles and dirt (or sand) to use in your rabbit diorama.
Make a background in the shoebox that will represent the ground and sky. Construction paper is excellent for covering dioramas, but tempera paint is also a good choice.
Add details to the diorama's background. Cotton balls make excellent fluffy clouds. Dirt or sand collected from your nature walk can be sprinkled on a thin layer of glue to add depth and interest.
Cut construction paper to create trees, grass or streams of water. Gluing in small twigs or pebbles collected on your nature walk will add another layer of detail to the diorama.
Draw or cut out pictures of rabbits to place inside the diorama or purchase miniature models from a craft or hobby store. When cutting out pictures of rabbits, cut an extra length of paper at the bottom of the rabbit. Bend the extra paper backwards, like a tab, so the rabbit stands when it's glued in place.
