Try a twist on the old finch beak and chopsticks activity by using M&Ms on a Twister mat. Spoons, knives, forks, and chopsticks represent beaks and are randomly assigned to your little birds, who must collect as much food as possible in 30 seconds to survive. In order to add more variety, add other textures and sizes of candies to simulate different food types. Note: If you are allowing your kids to eat their spoils after the natural selection game, make sure the Twister mat is clean.
