On Friday, I gave the kindergarten scientists a piece of basswood, safety goggles and a paper plate and posed the question...How can you change wood? We had a good discussion and thought about lots of ways (many unsafe for kindergartners) we could change wood. Next we handed out sand paper and talked about it...what it looked like, how it felt, etc. We decided to see if we used the sandpaper on the wood, would it actually change the wood? We got to work!
We predicted that we would collect lots of sawdust on the paper plates. We all sanded for a long time and got pretty tired doing it. We did not collect as much sawdust as we anticipated, but we were able to change the wood by sanding it! We also noticed how smooth the wood samples were where we were sanding them. We are excited for more science investigations on wood!
