what you discovered during your observations, from your data table(s) and graph(s).

• Begin by explaining what happened in the experiment. Outline the process you used and the data that you collected. After you have described what happened in each experiment, you can begin discussing what can be learned from the data.

• An analysis includes only facts, no opinions!

1 to 2 sentences with an overview of what you did in the experiment.

In our experiment, we chose one volunteer to try all four activities: running, weight lifting, walking, and yoga. After doing each activity for the same amount of time, we measured their heart rate three times for a total of three trials.

3 to 4 sentences that share the data that you collected.

For running, the volunteer had an average heart rate of 130.3 beats per minute. For weight lifting, the volunteer had an average heart rate of 105 beats per minute. For walking, the volunteer had an average heart rate of 86.3 beats per minute. For yoga, the volunteer had an average heart rate of 72 beats per minute.

2 to 3 sentences explaining what the data that you collected means.The data we collected shows that a person’s heart rate is highest when he is running, but a person’s heart rate is lowest when he is doing yoga. The order of activities and the heart rate they produce from highest to lowest is running, weight lifting, walking, and yoga.
