# Graphing ClaimsEvidence

Document Sample

```					GRAPHING & CLAIMS/EVIDENCE
An experiment is done to test how exercise impacts heart rate. The
subject had a resting heart rate of 65bpm. They did jumping jacks for 1
minute and took their pulse. Then, they exercised again for a minute and
took their pulse. They did this for five minutes. The results are below.

Make a claim and provide evidence to as to the impact of
exercise on heart rate.

Claim                   Evidence
Exercise increases a    Resting heart rate was 65 beats per
person’s heart rate.    minutes (bpm). After one minute of
exercise, the heart rate was 90 bpm.
The maximum heart rate was 130 bpm
after exercising for 5 minutes.
Conclusion

Exercising increases heart rate. Resting heart
rate is approximately 65 bpm. After
exercising for only one minute, heart rate
increases. The heart rate never decreases
back to the resting heart rate. The extra
work/effort done during exercise causes the
heart to beat faster.
