Today we did a rocks and minerals project.
We had toothpicks and cookies and we dug up all the chocolate chips and it felt like I was operating the cookie.
My hypothesis was 5 chocolate chips on the top and 8 on the bottom. I dug up all I could on the top and on the bottom it was fun and a school activity so I really enjoyed it and I hope we do it again.
Continuing with the hypothesis, unfortunately, it was wrong there were 12 on the top and 7 on the bottom but it’s ok because it’s a prediction they’re not always right.
I have chosen to make a barn elevator.
What pulley system does your choice include: I used a Fixed Pulley system for my project.
Explain how that system works: You have to roll the dowel while the dowel rolls up the elevator.
Scientific Process- Hypothesis
What is your hypothesis (what will happen when you pulley your pulley machine): You will pull the dowel while the dowel rolls up the strings which is pulling up the elevator.
Scientific Process- Conclusion
My Hypothesis was correct.
I thought if I put 1 string on the left side same on the right side it would balance the elevator while I pull it up
