Coming soon: A full-length video about bones. Don't disregard this in the meantime, however. It's a valuable introduction that you could insert into your lesson about the skeletal system. With a silly Texas accent, the narrator covers how many bones we have, what the role of the skeletal system is, the largest and smallest bones, different types of bones, and even names the more significant bones. What makes this resource most useful is that it comes complete with links to a related article, a multiple-choice quiz, and printable activities including a cut-and-paste skeleton. Make no bones about it, this resource will add structure to your human body systems unit!
