Animals without bones
I can compare and group invertebrate animals, based on the structure of their bodies.
Lesson details
Key learning points
- Some animals do not have any bones.
- Animals that do not have bones, including a spine, inside their bodies are called invertebrates.
- Some invertebrate animals have a hard layer or shell for protection on the outside of their bodies called an exoskeleton
- Some invertebrate animals' bodies are filled with fluid, such as worms and jellyfish.
Common misconception
Pupils may believe if an animal has a head, extremities and an external skeleton it is a vertebrate.
Share images of lots of animals with exoskeletons and compare them to a knight that puts on armour to protect themselves from injury.
