Question: Water and paper clip experiment?

This experiment was a test run with the goal of teachings us, the students, the format for the IB Biology lab format.

We had a plastic cup filled to the rim with water. We had to add jumbo paper clips to the water. Our goal was to find out how many paper clips it would take to over fill the cup. Now I know what the science behind that is but I cannot explain it so I need help with the lab write up.

Would this be a sufficient and logical write up about why the water over flowed?

The cup and water in the cup remain the same but when paper clips are added the water rises because of the increased volume.

Answer: it follows the concept of limited space… it’s like in your room… u can only fill 100 people… as u squeeze 101, 102, 103, 104… u begin to reach a point where you CANNOT fill anymore… due to the fact that VOLUME within the room are FILLED and completely saturated…. same applies with the water in the CUP… cup occupies with water with certain amount of volume… so does the paper clip… displacement in Volume occurs when you put more paper clip in it… which will push the volume of water up….and overflow…

Question: Is this a good science fair project?

every year in april my school has a maditory science fair… I got 1st place this year… on How does Human Interaction with a Pack of Demestic dogs affect the hierarchy of the pack?… I was thinking doing How much Science is involved in the production of a meal? for this next years and making a video like good eats… in our school it doesn’t have to be an experiment… does that sound like a good project?

Answer: That sounds interesting. It could be good. I’d suggest running it by your teacher and see what he/she thinks.

3 Magical Science Experiments You Can Do At Home! – Part 2

Question: Trying to identify 2 children’s/young adult books?

I remember reading these when I was young, but can’t remember the names.

1) a genius girl haunted by some sort of flashbacks to the Holocaust; it turns out she is one of a number of clones from a brilliant scientist who was in a concentration camp. The clones are all science-orientated until they’re teens at which point, more individual personalities begin to show up. The authorities consider this a failed experiment.

2) A disease wipes out the entire adult population (everyone over 13 or 15), and the children have to figure out how to survive. I recall stuff about holing up in an old school building, managing to drive to grocery stores and warehouses, and fighting off other children. Set in a Chicago suburb.

Thanks for the help!

Answer: I think that the second one is probably ‘The Girl Who Owned A City’ by O. T. Nelson

I’m sorry, I can’t help you with the first.
