Label the Human Skeleton: Free KS2 Science Worksheet

What is on the worksheet

The worksheet shows a single, front-facing human skeleton drawn in simple line art, with six numbered markers on the main bone groups: the skull, the ribcage, the backbone (spine), the arm bones, the hip bones and the leg bones. Children write the name of each numbered part on its line, using the word bank. Two short questions then ask what the ribcage protects and what the skeleton's three jobs are. Finally, children colour each bone group, which reinforces where one part of the skeleton ends and the next begins.

How to use it at home or in the classroom

Print the sheet on plain A4 paper. Before children start writing, ask them to point to each bone group on their own body and gently feel where it is, for example tapping the ribs or running a hand down the spine. This links the diagram to their own experience. Children then use the word bank to label each part, and colour the diagram afterwards. As an extension, ask why each bone group is useful, for example that the skull protects the brain and the ribcage protects the heart and lungs. The colouring stage also makes a calm, focused activity for the end of a lesson or a quiet moment at home.

What your child will learn

Children will be able to name the main bones of the human skeleton and locate them on a diagram and on themselves. They will understand that the skeleton has three big jobs: it supports the body and helps us stand upright, it protects soft organs such as the brain, heart and lungs, and it allows movement by giving muscles something firm to pull against. Many children picture bones as dry and lifeless, like a museum skeleton. It helps to explain that the bones inside us are alive: they grow as we grow and can mend after a break, which is why a broken arm is held still in a cast while it heals.

A note for teachers

This sheet supports the statutory Year 3 objective within Animals, including humans. The labelling uses everyday, age-appropriate terms (skull, ribcage, backbone or spine, arm bones, hip bones, leg bones) rather than full anatomical names such as cranium, vertebrae or femur, which keeps the cognitive load suitable for lower KS2. If you wish to stretch more confident pupils, you can introduce the correct scientific names alongside the simpler ones, or ask children to add the matching organ that each bone group protects. The word bank can be folded under or covered to turn the task into a recall activity for assessment.
