Animal skeletons

I can compare and group vertebrate animals based on their skeleton.

Lesson details

Key learning points

  1. Different animals have different skeletons, including its size, shape and number of bones
  2. A skeleton that is inside of the body is called an endoskeleton
  3. Animals that have a spine inside their bodies are classed as vertebrates

Common misconception

Children often believe 'bendy' animals do not have a spine so classify them as invertebrates.

Use images of X-rays/ skeletons of snakes and eels will illustrate that they have spines and are therefore vertebrates.

Keywords

  • Skeleton - A skeleton is the set of bones inside an animal's body that supports its shape, helps it move, and protects important parts.

  • Compare - We compare things by looking at what is the same and what is different.

  • Endoskeleton - Animals with an endoskeleton have an internal skeleton.

  • Vertebrate - A vertebrate is an animal with an internal skeleton, including a spine.

  • Spine - The backbone of an animal is also called its spine.

Whenever possible allow them to handle real snake skeletons to show the jointed vertebrae in the spine. Illustrating how humans can bend and curl up like a snake will help them understand that spines are flexible and can move in this way.
