We did the science fair this year for the first time. It was seriously a lot of work! Jaxton picked a topic about freezing liquids. He knew that things expand in the freezer, so he wanted to find out which kinds of liquids expand more. He chose to use milk, water, 7up, orange juice, sugar water and salt water. He out each liquid in a glass jar at 8 ounces. 24 hours later he checked on his liquids. He did some before and after observations. He found that the soda expanded the most-2 more ounces. We did some research together on what happens as liquids freeze and what happens to the atoms and molecules. We took it to basic chemistry and talked about how water is made of H2O and carbonation in soda is made of CO2. Seeing the oxygen in both of these, he made some conclusions based on the idea that oxygen maybe makes things expand...? It was a fun project for him. And I really enjoyed the one-on-one time I got to spend with him. I love to teach my kids new things. I got to teach him how to create a graph and how to plot his results. Once he grasped the idea, he took it did the entire thing. He actually enjoyed it so much that he didn't want to stop working on his project for 2 days straight. He wouldn't quit! He really was motivated to learn and study and create his board. I was very impressed with his responsibility of the project. And oh my was he proud. He was so confident in his work. At the science fair he had to stand by his board and tell people all about it and answer their questions. Great work Jaxton!
