What have we been learning about in science?

Moving and Growing : Week 1: What did we learn?

1. That many animals have a bony skeleton but some do not have a skeleton.
2. That many animals have an internal skeleton (e.g. cow, frog, fish, cat).
3. That some animals have an external skeleton (e.g. crab, beetle.).
4. That a few animals have a hydrostatic (watery) skeleton (e.g. jellyfish, slug, squid).
5. Why do we have a skeleton?
1. Our skeleton gives us our shape.
2. Our skeleton gives us support.
3. Our skeleton helps us to move.
4. Our skeleton protects the soft bits inside (e.g. the skull protects the brain; the ribs protect the heart and the lungs).

Moving and growing : Week 2  :  What did we learn?

1.     We looked at real bones and thought about suitable adjectives to describe their properties – hard, strong, smooth,

2.     We examined some x-rays and decided that although bones are strong they can break.

3.     That skeletons are frameworks made up of bones and softer material called cartilage

4.     We learned the names of some important bones that protect our organs – ribs, spine, skull

Moving and growing : Week 3  :  What did we learn?

1.    That bones in children and adults are different sizes – the bones change as we grow – we measured a femur bone in a

3yr old child, ourselves and an adult.

2.    That the circumference of a child’s skull and an adult’s skull is almost similar throughout their lifespan – we measured a 3yr old, ourselves and a fully grown adult.

3.    That we can represent data collected as a graph or a chart

4.    That we can draw a conclusion from our results table after collecting data in a fair test.

5.    That our bones grow longer and bigger as we grow older

6.    That our skull does not grow in size much but that the bones in our skull fuse together as we grow older.
