The twos, threes and fours become food, shelter, and space. When a habitat component is being food, it clamps its hands over its stomach. When a component is being shelter, it holds its hands above its head. When it's being space, it holds its arms slightly out from its body. Components of Habitat Everyone individually chooses which habitat component they are looking for or representing at the beginning of each round of the activity.
Teacher asks students to make their signs.
Once everyone is making their sign, count to three and each line of students turns to the other. This represents the salmon successfully meeting its needs and reproducing as a result. Any salmon failing to meet its needs dies, and the player becomes part of the habitat. Teacher records the number of salmon at the beginning of the game and at the end of each round. Play about 15 rounds at a brisk pace, each round representing one year.
