Science club – Skeletal system

I got a book for my birthday this is it, which provided photocopiable resources to make a paper anatomy model, so I thought it would be fun to spend some time working through that with our science group.

The first week was all about bones.

Week One – Skeletal System

Arrival Craft: Paper skeleton from Scholastic model book

 

Introduction: We’re going to be looking at human bodies for the next six weeks. We’re starting this week with the skeletal system. Does anyone know why our skeletons are important?

They give structure to our bodies.

Hopefully, you’ve all made a good start on making your paper skeletons. But, in real life our skeletons aren’t made of paper.

A joint is the point where two or more bones meet. There are three main types of joints; Fibrous (immoveable), Cartilaginous (partially moveable) and the Synovial (freely moveable) joint.

If our bones were all joined with sellotape, we would have flappy joints. Actually, our bodies have several types of joints. We’re going to make some models of them now.

 

Individual task:Make ball and socket, pivot and hinge joints, using materials from the Scholastic book.

Experiment to find where these different types of joints are on our bodies.

Break for drink and snack

 

Re-gather: Lay out the big skeleton picture.

Ask the children if they know the names of any of the bones. Lay the bone labels on the skeleton together.

Our bones can’t move by themselves. Does anyone know what we use to move our bones?

Skeletal Muscles move bones (smooth muscles are found in involuntary movements such as your stomach and your bladder; cardiac muscles are in your heart).

These fibrous tissue masses contract to pull bones in one direction, so they are found in pairs – so that you can move back again!

 

Individual task: Experiment to measure arm width when muscle is relaxed and contracted. MuscleExperiment
