Puffer Paths
• Key Question: How many puff does it take to move your sheep from the pasture to the sheep pen? (See game board.)
• Materials per student to make a cotton ball “sheep” : drinking straw, cotton ball, chenille stick (pipe cleaner)• Materials per group: game board and tally sheet• Game Objective: Count and record the number of puffs it takes to blow a cotton ball “sheep” along a path on the game board. Compare your group’s data to the data for the whole class.
