  1. Structure of the Human Bone

  2. What does a human bone look like?

  3. What does a Human bone look like if we cut it in Half?

  4. DO you know what the structures are called with in a Bone?

  5. Let’s do an experiment to find out what the inside of a bone look likes

  6. Write your prediction of what will happen if we cut this bone open. What do you think you will see and do you think you will see this PREDICT

  7. Let’s have a look inside of a cow bone What do you see , let’s write this down on your investigation planner OBSERVE

  8. What the inside of a bone looks like

  9. Inside a Bone • A fully developed bone is made up of mineral salts, water and tissue. There are two types of bone - compact and cancellate. A compact bone is smooth and solid, while a cancellate bone is a much lighter structure. The structure of the cancellate bone is similar to a honeycomb. All bones are a combination of cancellate and compact bone. • Inside each bone is a jelly like substance. This is called bone marrow and is at the centre of the bone. This marrow produces blood cells for the body. Blood vessels run through the centre of the bone so that the bone receives food, oxygen and minerals.

  10. Inside a Bone • Your bones are alive and have living cells growing inside of them.  Bone cells are called Osteocytes.  They take in food and give out waste.  There constantly need repair.  Bones are made 45% minerals/Calcium Phosphate.  Which gives bones there hardness.  Also bones are filled with red and yellow jelly stuff in them... this stuff is called marrow.  The yellow marrow stores fat and releases it when it is needed else where.  But the red marrow is tissue that make red and white blood and white blood cells in big amounts.   Your body produces at least 5,000 white and red blood cells every day. Your bone is like a microscopic honey comb with tons of spaces for blood cells and nerves to get.

  11. What do you think of the differences between your prediction and the what you actually saw inside of the bone Let’s amend or add onto your prediction from the new information that you have learnt today EXPLAIN
