This is an activity (on page 2 of the PDF) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility and strength. Learners will submerge 3 chicken bones in water, bleach, and vinegar, wait 24 hours, then observe and test each bone. This resource includes information about how nanoscientists are trying to produce artificial analogs to these components and relates to linked video, DragonflyTV Nano: Bone Regrowth.
