Most people will break a bone in their body at some point in their life, but how much force does it take to break one? In this activity, learners will experiment with weight and discover how much force is needed to break a chicken bone. Step-by-step instructions are included with photos along with safety recommendations. Activity guide includes a “What’s going on?” explanation and connections to relevant science concepts such the physical nature of bones, the function of calcium and collagen in bones, and exercise and bones.
