Which Came First? The Chicken or the Egg


6 and up


Students will explain which came first, the chicken or the egg, and justify their response.


  • paper
  • resource materials, e.g. encyclopedia.


  1. Read the paragraph at the bottom of the game page. What would happen if all the eggs hatched?
  2. Have students identify the things that can keep eggs from hatching.

Have students play the game individually or in small groups. Each student starts with 24 eggs. The students flip a coin to move one or two spaces. (See game board.) The student keeps track of the 24 eggs throughout the game. Lost eggs are placed in an envelope. The one with the most eggs at the end of the game is the winner. At the end of the game, ask students which of the hazards in the game are caused by people? (too high or too low of temperature, too little or too much humidity) What can you do to protect the eggs?
