Heythere1:

Jason is on the track team. He runs almost every day, but his friend Caleb hardly ever exercises. Jason and Caleb decide to ride their bikes together to the store. After riding up a particularly steep hill, Caleb notices that his heart is beating extremely fast. However, Jason's heart is still beating at a relatively slow pace. Jason and Caleb wonder why their heart rates are so different after biking up the hill. Caleb thinks that Jason's heart is probably beating more slowly because Jason exercises more often and is in better physical shape. The two boys decide to test Caleb's idea. 1. How are Jason and Caleb thinking like scientists?

Jason and Caleb are thinking like scientists because they are making observations, forming a hypothesis, and planning to test it. Jason observes that his heart rate is slower compared to Caleb's after biking up the hill, and Caleb proposes a hypothesis that Jason's heart rate is lower because he is in better physical shape from regular exercise. They then decide to test the idea, which is the next step in the scientific method.
