Our Float Your Boat Lab (what?!)

I wrote that at the top because the title is kind of ironic. Plus, it gets your attention. And I really need people to visit my blog. 


So we had this preliminary experiment. We got several 12cm x 12cm squares and were told to make a boat that'd hold as many pennies as possible. Some results were pretty weird, and Mr G told us to make a lab up that was kind of like our first. 


So my team had this unique idea. See, my classmate had this flair for making unusual boats, and he made one that looked like a catamaran. That boat held a LOT of pennies. Naturally, we decided to change the shape of the bottom of the boat. 


So we had one with a flat bottom, one catamaran, one shaped like a bowl, and one in which the bottom curved inward. Guess which ones held more!


Well, the catamaran and the one curved inward held very few on average. The one with the highest average? THE ONE LIKE A BOWL! And the flat one was only one lower. It was very confusing. 


So does anybody have a scientific reason  WHY this happened? We have a wild guess, which I won't write down because in reflection, it makes no sense.

hey andrea! i'm aliza from mr. ullrich's earth science class. nice post. for ur lab, i think the bowl-shaped boat held the most pennies because it had the most space. the flat one only held a little less because you probably made that one with a large depth inwards but not curved at the bottom. i hoped this sort of helped calm ur confusion... (because it was just another wild guess!!)

kk, happy labwork!

I don't really have an idea. But that is wierd. It sounded like a fun project though! I wish we could do something like that in our class. What was you idea? I couldn't really think of anything that would have made a lot of sense.
