Great activity! I love the combination of videos, game play and time for discussion. It does a great job of teaching about the food chain, and also helping kids to be more aware of their surroundings by making observations of the environment. It also promotes critical thinking. The game is fun, but you need at least one other person to play it with. But it is possible to play a modified version by yourself, where you draw a card, and then try to make extra long food chains.
