Science Fair 2011

Well, it's that time of year again, science fair time! As you know we love these and even though this year it wasn't required for Sarah, she still participated - with my encouragement. (O: We looked online for several ideas and she liked the idea of doing ocean science. We found this idea on sciencebuddies.com It's called, "Can Water Float on Water?" And we both were fascinated with what we learned. Basically we inverted different water substances on top of each other in the water bottles. We made different solutions - fresh water, salt water (various amounts of salt), warm water and cold water. We tried salty on top of fresh, warm on top of cold, etc. It was very cool. The ones like below that didn't mix colors seemed to be happy right where they were.




The one above, was an example of different solutions that wanted to switch places. The cold water on top was more dense and wanted to be on the bottom. The warm air wanted to rise up. The colors mixed to green in these cases.

Sarah worked so hard on this. I helped her lay it out, but she did almost the whole thing. This year was also particularly hard because the science fair is more demanding than the ones we participated in in Oregon. Here, you have to not only make a poster, but put together a binder with all kinds of information. It took hours to put just the folder together.

When Sarah came home from school the next day, she was sooo excited. Her project was chosen to go to district! This will be her third year in a row doing a district science fair. Way to go Sarah!
