There are countless other science programs available on the Internet.
Many people are asking: “What supplements (additional informational resources) are necessary to go along with BFSU?”
Let me say that BFSU is a curriculum that can stand on its own. It is certainly good to refer to other sources for expansion and reinforcement and have kids see that other sources tell the same “story”. However, please don’t feel that BFSU needs be supplemented with any particular resource or resources. Indeed, the best way to supplement BFSU lessons is to draw kid’s attention to what they can see and experience in their own lives, and to discover how their BFSU Lesson lends to their understanding of the real-world. See the “To Parents and Others Providing Support” section of each lesson.
