Hypothesis: I think that my muscles will take a while to fatigue
Equipment: A spring-loaded clothes peg
Method:
- Hold the clothes peg as shown in the diagram below
- 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 experience muscle fatigue
Results: The more that I moved the peg, the more my muscles started to feel pain. My muscles were exercised more the longer I did it. In relation to my hypothesis, I was wrong.
Conclusion: I saw that peg was slowing down because my muscles got tired
Evaluation: I would try to go for longer and see how much more it hurts
Hi Logan, Good first sciblog was good to see the aspects of scientific method- Aim, Hypothesis, Method, Results, Conclusion, Evaluation. It would be good to have a discussion with your conclusion so that it covers the following points: Conclusion- do your results match your hypothesis. eg. My results did not match my hypothesis as my fingers got tired quickly.
ReplyDeleteDiscussion- why did it happen? My fingers got sore as all of the energy had been used up, and there was not enough oxygen left to respire aerobically, so only a little bit of energy was made to use.
Hope that helps.
