The program has enough structure that I do not have to pull together material for science which often leads to delays a loss of student interest. The support books remind me of Usborne Internet Linked Encyclopedia. The e-books are wonderful full color guides to interesting and up to date websites. The only drawback is The World of Plants textbook which was just not a good fit with the rest of the program. We supplemented with a standard 3rd Science text.
We have had a lot of fun understanding the nature of plants and growing our own balcony fall/winter garden. We have explored several local community gardens understanding the pollination and seed travel. There have been tons of cool experiments, so much so our kitchen table looks like a botany lab.
Our first experiment was the growing of a bean from seed to plant. Ironhide was beside himself because he was actually growing food. He got so into it we added kale and more beans to the lineup.
