Ecosystem: Food Web

Toss around a ball of yarn and see how all creatures are connected in an ecosystem! Each child catches the ball of yarn, calls out one component of the food chain in an ecosystem, following their previous classmate's response. Continue to circulate the ball until everyone is holding on to a piece of yarn. Tell students to pull tight! Then, say a tree got cut down or some aspect interfered with the ecosystem. Cut the string and see how "creatures" get affected by one change.
