If your child hasn’t witnessed a caterpillar in nature, then this is the best chance to introduce the concept of butterfly metamorphosis.
To begin with, I have used beans. If bean isn’t available at home, then pea can also be used instead.
Take a white sheet of paper and ask your child to place the beans randomly on the paper.
Fix the beans either using a glue or cellotape.
Define the beans using black pen to create caterpillars.
Ta-da! Your caterpillars are ready.
