We like science around here. Aside from the normal outside science discovery play in Kindergarten, we had a few scheduled activities that we did. The major part of our science time was spent with Real Science 4 Kids.
The Real Science 4 Kids: Pre-Level Chemistry has been a great fit with my kids. I purchased this curriculum back in 2007 and have used it with all three of my kids. I find it to be packed with real science that is understandable for a younger child. The textbook pages have fun and colorful pictures or drawings that help explain the concepts. The set comes with a textbook, a teacher’s manual, and a child’s lab manual. It is quite expensive for a science curriculum for a young child. Since I have used this one multiple times, it was money well spent.
I highly recommend the Real Science 4 Kids curriculum. I didn’t end up purchasing any of the other ones because of the price, but if you are looking for a quality science curriculum for your young child I don’t think you can go wrong with Real Science 4 Kids. I’ve heard that is it difficult to find used, but if you do find it I would jump on it.
