The science fair is tonight at school and that means a lot of kids have spent the past few days scrambling to finish. Laura was no exception. Here are a couple of pictures of her doing experiments to test the electrical conductivity of sports drinks. She is finding out if sodium content of the drinks is related to its conductivity and whether those that claim to have more "electrolytes" (which sodium is) have better conductivity. Sue is running the fair again this year. She is such a good teacher. :)
