100 Days of Science #17-- We Made an Iceberg!
When we were reading the book The Titanic Mission I saw an experiment about icebergs in our book and just knew we had to try it.
First we found a balloon and filled it up with water and stuck it in the freezer overnight.
The next morning we removed the balloon and were left with an oval chunk of ice.
We then measured the ice and made note of how big our ice chunk was-- horizontally and vertically.
We put the ice in our bowl and measured how much of the ice we could see from the top of the water to the top of the ice.
There was hardly anything showing! 90% of most icebergs are underwater!!
The boys then hypothesized that ocean water would be a bit different since it was salt water and therefore more dense than normal tap water.
We took out our iceberg and added a lot of salt to our bowl. We really had no idea if we had as much salt as the ocean but we could see flecks of salt so we figured we might be pretty close.
We added the ice back into our bowl.
There was hardly any change at all! While salt water is a bit denser it is not dense enough to make a difference in how icebergs float.
Most of the icebergs remain submerged in the ocean which was one of the reasons why the Titanic still hit the iceberg even though it turned. It had only avoided the portion of the iceberg it could see and hit the larger part that had still been submerged under water.

I am always looking out for new, fun activities to do with the children, so will be giving this a try #familyfun@_karendennis
ReplyDeleteI hope you like it; we thought it was a lot of fun.
DeleteThis is soooo COOL!!!
ReplyDeleteThank you!
DeleteWhat a fun experiment! Thanks so much for sharing at the #happynowlinkup!
ReplyDeleteThanks! I was so pleased it fit right into what we were already learning about; I love when happy accidents like that happen.
DeleteWell that’s very interesting. For any children who know of or have watched titanic I can imagine it is really fascinating for them. Thanks for joining us at #familyfun
ReplyDeleteIt was really neat!
DeleteOh this looks fun! We're due some polar weather this week here in Ireland and my boys love everything Titanic-related, so we'll defo have to try that!
ReplyDeleteComenting belatedly from #FamilyFun
I hope they like it! My boys thought it was very cool.
