Introduction
In the unit 'Moving and growing' # learnt about how the skeleton is related to movement and support in humans and what happens to the skeleton and muscles as they move. ^ has also compared human bones and skeletons with those of other animals. ~ experimental and investigative work focused on * turning questions into a form that could be investigated and collecting sufficient evidence. ^ make ~ own observations, measurements and comparisons and then interpreted ~ evidence. The work in this unit offered * opportunities to relate ~ understanding of science to ~ personal health.

Skeletons
Section 2: Bones and skeletons

^ was able to identify similar parts of the skeleton in different animal species.
^ has made a list of the similarities between different animal skeletons e.g. they all have spines (or backbones) and skulls. ^ has also obsevered and recorded the differences e.g. the cat's bones are much smaller than the human bones.

Skeletons 2
Section 3: Comparing skeletons

^ was able to describe the characteristics of bones as materials e.g. the bones are hard, strong and ^ was successful in identifying differences between the bones of different animals e.g. the fishbones were much smaller and easier to break.
^ is able to locate and name some bones e.g. ribs, spine, skull.
"
Testing
Section 4: Growing & Section 5: Testing ideas about body size

^ has stated that ~ skeleton grows from birth to adulthood. 
^ could decide how to investigate how ~ body changes over time.
^ was able to make measurements of bone lengths to the nearest centimetre and describe what ^ had done.
^ was able to construct ~ own bar charts or pictograms and make comparisons between the different results. ^ could describe what ~ results showed and ^ was able to explain whether ~ prediction was supported by ~ evidence.
"
Muscles
Sections 6-8: Supporting the body

^ has explained that all bodies need support, but that not all animals have an internal skeleton to do this.
^ is able to explain that in order to move, e.g. ~ arms and legs, a muscle, attached to a bone, has to contract.
^ can relate muscle movements to other parts of ~ bodies such as ~ face and ~ back.
^ knows that as one muscle relaxes another contracts and this results in movement.
^ has given descriptions which show that ^ understands that ~ muscles work harder during exercise than when ^ is sitting still.
