After reading Rachel Tonkin's wonderful book "Leaf Litter", we began to think about the connections each animal and plant had to one another in this habitat.
After drawing a huge tree on the floor with chalk onto the carpet (.....sorry....to our cleaner), I gave the kids a a card with an animal or plant on it from our story. Starting with one student, other students joined in one by one, explaining the connection as they joined the habitat of the tree.
We then took this concept a bit further. Each creature (student) took the end of a stretchy ribbon and made a connection with another creature. More and more connections were made until it was truly an interconnected web.
We had a lot of fun while the kids learnt how the food chain is linked.
Students also thought about possible interruptions to the food chain and the implications to the creatures and their habitat.
