February was science fair month at our house.
Rachel did a project looking at the effect of soda on eggshells as a surrogate for teeth because eggshells consist of the same material as teeth. It was a great project and took first place at her regional science fair. She will go on to compete in the state competition.
Of course, all the kids wanted to participate in the elementary school science fair this year. I told Paul if they signed up, he would be in charge of helping them because I have my hands full with the babies. He agreed. It was quite a big job to help kids with three projects at the same time.
Spencer's project focused on propulsion. It was a complicated project and required lots of persistence in order to make it work. He demonstrated propulsion on a balloon-propelled airplane connected to a fishing line. They tried different types of airplanes and different things to connect it to the fishing line. After several failures, they were able to get the airplane to propel all the way across the yard. In addition, they built a raingutter in order to do the same thing with a balloon-propelled boat. Ultimately, they were successful. Paul and Spencer had a great time working together.
Caitlin learned about the solar system and made a model of our solar system.
Courtney observed ice cream melting in order to determine which ice cream melted faster. She discovered that orange sherbet melted the slowest while chocolate melted the fastest.
