Equipment:
- A Spring-loaded clothes peg
Method:
- Hold the clothes peg between your forefinger
- Relax your fingers so that the peg closes all the way
- Squeeze your thumb and forefinger so the peg is fully open
- Repeat steps 2 and 3 as quickly as you can until you experiences muscle fatigue.
My fingers started of going really quick and then they started to get sore and slow down until they got tired.
Conclusion:
I saw the peg open and close.
Evaluation:
I would do nothing different.
Good start Marshall- it was good to see the headings for a scientific method used (aim, method, results, conclusion, evaluation) however you were missing some of the ones I asked for- Hypothesis and discussion.
ReplyDeleteNext time there should be a hypothesis after your method, what do you think is going to happen in the experiment. This would mean that you would be able to write about your hypothesis in your conclusion- as a conclusion should say if your hypothesis was right or wrong based on your results. You should then have a discussion on why you think your results happened- eg. My fingers slowed down because I had used up the energy in the muscles and I could only anaerobically respire to make more energy.
Grade- 4/10 as missing the hypothesis!
