Skeletons & Teeth

Humans and certain species of animals are able to move around everyday because we are supported by an internal skeleton (a skeleton on the inside) all vertebrates (animals with a spine) such as fish, reptiles, amphibians, mammals and birds all look very different to each other at first glance but surprisingly share some basic characteristics. But over time will have developed certain adaptations to allow them to survive in their chosen habitats.

Animals such as invertebrates (animals with no backbone/spine) are built quite differently, some having an exoskeleton (skeleton on the outside) to protect them. Having no backbone makes the animals very soft and flexible, making them easy prey for predators, resulting in the exoskeleton protecting it like a suit of armor.

Our skeletons are anchors for our muscles, which then pull our bones in different directions. It also provides you with support and protection. Without a skull protecting he most vital organ in our body it would be very badly damaged.

Teeth

All animals including humans are adapted to eating certain types of food. Animals such as herbivores are plant eaters and have flat teeth for grinding. Carnivores, meat eaters have sharp teeth for tearing and omnivores will eat both plants and meat, have both flat and sharp teeth.

Most insects, arachnids and invertebrates have slightly different teeth than that of other animals most having teeth called mandibles or fangs.

Core Focus

  • What is a vertebrate / invertebrate?
  • How do we move, how are we similar?
  • Do all invertebrates have an exoskeleton?
  • What are the differences between the different types of teeth?
  • What are animals able to eat?
  • How do we move?

Animals to use

Insect – exoskeleton, three body parts, 6 legs
Arachnid – exoskeleton, 2 body parts, 8 legs
Millipede – multiple body parts, exoskeleton, 250-400 legs
Snake – long spine, ribs and skull
Frog – same bones as humans only smaller with different adaptations
Mammal – same bones as humans only smaller with different adaptations
