Introduction

Animals have different ways to keep cool in hot weather. Jackrabbits lose heat through their big ears, dogs pant, and you sweat. Body size affects cooling rate. Shaquille “Shaq” O’Neal is the 315-pound, seven-foot, one-inch center for the Los Angeles Lakers basketball team. Susie Chang is the 78-pound, four-foot, eight-inch point guard for the Milan (Indiana) Middle School Indians. Who do you think cools faster—Shaq or Susie? In this experiment, you will first predict who cools faster. Then you will do an experiment to test your prediction.

Objectives

In this experiment, you will

  • Predict which cools faster, a large body or a small one.
  • Use Temperature Probes to test your prediction.
