My daughter takes classes for homeschoolers at our zoo, and each time she gets an award certificate from the education department. We do occasional behind the scenes tours with the keepers, but this is a different program specifically designed for area homeschoolers. It’s way better than reading about the topic in a text, because the zoo has animals on hand (and skeletons of them-ew) to observe and touch/pet. After one of her other classes she totally creeped me out because she said they let the kids handle those GIANT cockroaches. I have the heebie-jeebies just typing that. The St. Louis Zoo is one of the top-rated zoos in the world, but others zoos probably have similar programs. If you homeschool, it’s worth investigating.
