Yes, we had a science center all year but with different themes for the year. We had things for physical, environmental, and chemical. We had different types of insects(dead) in magnifying jars. I remeber bringing in this huge wasp nest I found at my church. We had bones(fossils) we would put in the sand table for exploration. We also had food coloring to mix with water. Then there were live plants. The children loved our science center. Also, keep lots and lots of books, paper and pads for them to record their notes.
