remembering how to do science labs

Today was a lot of fun remembering how to do some of the science labs. It has been so long since I have done some of them that it was almost a new experience. I loved the other probes that we got to learn how to use them. I think it will be fun for my kids to use. As for questions on regard to content I wounder if I will feel confident with teaching messy math. I know that I will not have a lot of access to graphing calculators but I do want them to see the connections. I was wondering if there is a way to have the data already on the calculators without them doing the lab so that they can apply the math. I do hope that I will be more open to messy data this coming school year.  That way the kids will have richer discussions and more ownership of the lessons.
