Flashcard facts and information about bones

Biology Bits stories are a great way for you to learn about biology a little bit at a time. We’ve broken down information into pieces that are very tiny—bite-sized biology cards. Cutting out the cards will let you organize them however you want, or use them as flashcards while you read.

This set of bits will teach you about the main organ system that gives your body its shape: bones. To learn more about the science behind bones, visit Busy Bones.
