The next posts will be covering our experiments based on the FOSS Unit Wood and Paper. The first experiment had the kids exploring 5 types of wood blocks. It included pine, basswood, red cedar, plywood, and particleboard. After some observation, they learned that some of the wood came directly from trees, while particleboard and plywood were fabricated.
The kids decided to figure out which piece of wood was the heaviest, softest, prettiest, darkest, etc. I had pictures of the linden, pine, and cedar trees. I also had illustrations of the processes to make plywood, and particleboard.
