Animals have different ways to keep cool in hot weather and during activities. Jackrabbits lose heat through their big ears, dogs pant, and humans sweat. The rate at which animals cool down is effected by their body size. Shaquille “Shaq” O’Neal is the 315-pound, seven-foot, one-inch, former center for the Los Angeles Lakers basketball team. Suzie is the 100-pound, five-foot, one-inch point guard for the Springfield Middle School Hawks. Who cools faster—Shaq or Suzie? In this experiment, you will predict who cools faster and then do an experiment to test your prediction.


  • Predict which cools faster, a large body or a small one.
  • Test your prediction.
