Meda and I worked on her science fair project today. We decided that she could do a project about Sand Dollars since I have about a billion of them from my scuba diving days. Her question is "How many teeth do sand dollars have?" and her hypothesis (after much deliberation and thought) is "Sand dollars have about 10 teeth because that's how much will fit with how big they are". We labeled our test subjects and Meda got bored. We will work on it again later in the week. Here are the sand dollars.
