Scientific Method - 0391

How does your resting heart rate change depending on your position?

At a fixed height, I will drop objects on a trampoline 3 times and count the number of bounces.

I will test my heart rate by counting the heart beats in 2 positions: lying down and sitting.

Lucy: Sitting-59 bpm, standing-65 bpm; Bob: Sitting-51 bpm, Standing-56 bpm

Step one in the scientific process - what you want to answer in the experiment.

Do heavier objects bounce higher on a trampoline?

The activity that is used to test if your prediction is true or false.

A person's position affects their heart rate. The heart rate is higher if the body is upright.

The final statement that describes what you learned from the activity.

If standing requires more effort than lying down, then one's pulse standing up will be faster.

Golf ball: 4 bounces, Medicine Ball: 7 bounces, Baseball: 5 bounces

The experiment & data show heavier objects bounce higher on trampolines.

If there's an equal & opposite reaction then heavier objects will bounce higher off a surface.

A statement that can be proven true or false. It is often written as an "if-then" statement.

Results of an experiment that are often displayed in a graph, chart, or table.
