Do you have what it takes to survive as a fit predator or will elusive prey lead to your extinction? Find out in a creative natural selection activity. Using different colors and shapes of grains to represent different species and generations of organisms, your little hunters will try to collect as many as possible using forceps as beaks. To add some diversity to your predator populations, you could adapt the activity by having kids use tweezers, chopsticks, spoons, or other tools in addition to the forceps.
