- Which activities increased your heart rate the most?
- Which activities increased your heart rate the least?
- Was the order in which you ranked the activities accurate? (It's good to be wrong!) Explain.
- What changes did you notice about your heart rate as you became more active?
- Why do you think your heart rate changed when you were more active? What inference can you make? (Use pages 65–66 of your reference book to help you answer this question.)
1. Jumping jacks increased my heart rate the most. I predicted that because I know that when you do jumping jacks you are jumping and moving your arms at the same time, so that's double the exercise then the other ones.
2. Sitting increased my heart rate the least. I predicted that right too, and i predicted it because when you are sitting you are using the least amount of muscles compared to the others.
3. I ranked sitting to least increase my heart rate, then walking, then jogging in place, then acting like a fool, and to most increase my heart rate is jumping jacks. I ranked them in order from what uses the most muscles, because I think that the more muscles the harder you work. And the harder you work, the faster your heart rate is.
4. As I became more active, my heart rate went up. At the start my heart rate was at around 84 beats per minute. then at the end it was at 128 beats per minute.
5. My heart rate changed when I was more active because I was working hard. I'm not exactly sure, but I think this happened because my body needed more energy, so my heart beat faster to give it to me.
