  1. Are your bones alive? Absolutely. Bones are made of a mix of hard stuff that gives them strength and tons of living cells, which help them grow and repair themselves. Like other cells in your body, the bone cells rely on blood to keep them alive. Blood brings them food and oxygen and takes away waste. If bones weren't made of living cells, things like broken toes or arms would never mend. But don't worry, they do. That's because your bone cells are busy growing and multiplying to repair the break! How? When you break your toe, blood clots form to close up the space between the broken segments. Then your body mobilizes bone cells to deposit more of the hard stuff to bridge the break.

  2. A good way to become familiar with the size and shape of bones within the human body is to draw them. Half a skeleton has been provided for you. Use it to draw the other half of this skeleton.

  4. Determine the fracture Use the information given in your notes to determine which x-ray belongs to whom.

  5. What is bone marrow? Many bones are hollow. Their hollowness makes bones strong and light. It's in the centre of many bones that bone marrow makes new red and white blood cells. Red blood cells ensure that oxygen is distributed to all parts of your body and white blood cells ensure you are able to fight germs and disease. Who would have thought that bones make blood!?!

  6. How are red blood cells made?

  7. Do all critters have a backbone? No. In fact, some 97% of animals on earth don't have a backbone or spine. Remarkably enough, of those that do have a backbone, there are lots of similarities: a skull surrounding a brain, a rib cage surrounding a heart, and a jawbone or mouth opening. Animals without backbones are called? Invertebrates
