DS will be in 4th grade next year and enjoys reading and works well independently. We still do a “morning basket” together and I plan to continue having a science read aloud as part of that, along with doing nature study as a family. However, as he will be in 4th next year I am looking to add something else for science for him to do independently. I am looking at either Storybook of Science or Beautiful Feet Books program called History of Science. I understand that experiments will not be independent, and I am looking to stretch either one out over several years with just one chapter/lesson per week. Any thoughts on which is better? He really enjoys history, but I am not sure if History of Science will be too much to add on? How long does one lesson take? Thoughts on the experiments?
