Make a construction paper caterpillar which opens up to be a butterfly. Make caterpillar books. They could be in the shape of a caterpillar. Students use their knowledge to write a story of what happens to a caterpillar from the caterpillar's point of view. As the chrysalis starts to turn black and transparent, predict which of the chrysalis will become a butterfly first.
Students observe the chrysalis and butterflies.
They help feed the butterflies with sugar water. We also added real flowers in our flower garden box. When the unit was completed, reflect back to the very beginning and remember what the caterpillars looked like and what they developed into. Talk about the changes, and how this happens every year, year after year. After all discussions are complete, release the butterflies to their natural habitat.
