Scientific Process Project

Authors Note: This is my Scientific Process Project. You might have been apart of it, this is the project we tried to scare people. Enjoy our results.

Problem: Does screaming effect your heart rate more than jumping when scared?

Hypothesis: Screaming takes a lot of energy and if all you do is jump backward when you get scared most of the energy created by your heart is stored and increases your heart rate dramatically, but when you scream you release most of that stored energy so that would still increase your heart rate but less than if you jumped.

Experiment

Materials

-       Scary noise of some sort

-       3 or more masks

-       Blindfold

-       Different room

-       Rolling chair

-       Clean-up materials

Procedure

1.    Put blindfold on

2.    Roll chair to different room

3.    Test heart rate

4.    Scare the test subject

5.    Test heart rate

6.    Repeat with different test subject at least two times

7.    Clean up

Variables

CV – The scare, the scream, the jumps, heart rate tests

IV – how test subjects react, how test subjects heart rate is

DV – scream or jump

Control – the average persons heart rate

Conclusion

The people who screamed had a slower heart rate than the people who jumped instead, this is because screaming gives of a lot of energy so your heart rate will fall because all the energy you gave your heart by being scared cased it to speed up and when you screamed you released most, all, or even more than all the energy you gained, this causes you to lose the speed of your heart rate. If you didn’t scream you kept all the energy in side and your heart never slowed down but it speed up instead.
