Question/ hypothesis/materials Question – how does a different type of coin affect how many drops of water it can hold Hypothesis-I think that a smaller coin will hold more then a bigger coin because even those its smaller I think it will hold more water Materials- a penny , a quarter , an eye drop, a paper towel , one person

Procedure Step one – set up materials see diagram Step two – once you set up your materials make a guess on how many drops each coin will hold Step 3- for trial one do penny first how many drops does it hold then repeat step 3 but with quarter Step 4- record you data how many drops penny hold and how much quarter hold Step 5- repeat steps 3-4 two more times Step 6 – clean up with paper towel wipe up the water then see if you hypothesis

DATA TABLE Trial ONE Penny –42 Quarter –71 Trial 3 Trial 2 Penny-38 Average- Pennnies-34.7 Quarter-44.7

CONCLUSION In conclusion my hypothesis was wrong because I said that the penny will hold more but the truth was the quarter hold more the first trial was 71 ,2 20, and 3 43 the average was 44.7 the with penny it was trial 1 42, 2 24 , 38 the average 34.7 the difference was 10 so a quarter proved that it can hold as many drops of water then a penny can .

ABSTRACT The purpose of this project was I thought just because the penny is smaller it can still hold more drops of water then a quarter , and I believed that the penny would hold more but I was wrong there were no errors in my experiment and what I learned from this project that size matter to any thing the bigger it the more strong it can hold stuff
