Skeleton Explorer

About this simulation

Skeleton Explorer shows a simplified human skeleton in 3D. Students hover over a part to highlight it and click to read its name, a short description and how many bones it represents, while a counter tracks how many parts they have explored. A Pull apart slider separates the groups, Fade bones makes the skeleton see-through, and Quiz mode asks them to find parts, with a Next question button. It teaches that an adult has 206 bones and what the skeleton does, and works well for a lesson on body systems or as a revision game.

What students can explore

  • Hover over different parts of the skeleton and click the skull, ribcage and pelvis to read about each.
  • Drag the Pull apart slider to separate the bone groups and see how they fit together.
  • Switch on Fade bones to see overlapping parts more clearly.
  • Turn on Quiz mode, answer a question by clicking the right part, then press Next question.
  • Check Parts explored and try to visit every group of bones.

Learning objectives

  1. 1Name the main groups of bones in the human skeleton.
  2. 2State that an adult skeleton has 206 bones.
  3. 3Describe functions such as support, protection, movement and making blood cells.
  4. 4Locate bones such as the femur, skull and ribs on a model.

Questions teachers ask

Is it free?

Yes. It is free, needs no sign-up and runs in any modern browser, including classroom whiteboards, tablets and phones.

How many bones does an adult have?

An adult has 206 bones. Babies are born with about 270, and some of them fuse together as the child grows.

Are all the bones shown exactly?

No. The bones are simplified shapes and not to scale for fine detail. Hands and feet are drawn as groups that stand for 27 and 26 bones.

How does Quiz mode work?

Switch on Quiz mode, read the question in the Quiz readout, and click the part of the skeleton that answers it. Press Next question when you want a new one.
