Think like a scientist

Make a model skeleton

A model helps us understand how something works or see what

something looks like that we cannot see in real life. Work with a partner
to make a model of a skeleton.

You will need:

drinking straws and bottle tops, modelling clay or different shapes

of pasta, scissors, black construction paper or stiff card, paper

glue, white paper, a pen

• Look at the picture of the human skeleton. Notice the sizes and

shapes of the bones and how they are arranged.

• Plan how you will make a skeleton from drinking straws and
modelling clay or different pasta shapes. Your skeleton should show

these bones: skull, jaw, rib cage, spine, arm bones and leg bones.
