We’re not quite there yet, but oldest ds will be in 6th in the fall. This year with ds 10 and 8 together, we enjoyed Answers in Genesis science books 2x/wk with experiments (try to do the hands on before reading aloud), nature study (sometimes using Handbook of Nature Study, books from library), and notebooking 1 day, and online video presentations from Aurora Lipper’s Supercharged Science, some we purchased on Aviation, many others are free 1 hr webinars, they are very exciting and good for whetting appetites for further reading and experimenting. Thanks for the links and encouragement to continue with the living science books, I hope to assign him some( or spread strategically around the house, 😉 ,as he loves to read and likes science.
