Science: Animals

Last week you will have learnt that animals have to eat food to live; unlike plants, they cannot create their own food. Animals can have a huge variety of diets, but can be broadly labelled as either carnivores (meat eaters); herbivores (plant eaters); or omnivores (plants and animals). Humans are omnivores. Animals have a much more narrow diet than humans. We can see this every time we go into a supermarket and you see the huge variety of foods you can buy for humans, but for cats and dogs there isn't anything like the same variety. The basic food groups are: Fruit and vegetables; meat; grains (wheat, maize etc); sugars; carbohydrates; fats; dairy (milk, cheese, yoghurts); drinks. You probably found most, if not all of these in your house. What we are starting to understand more and more is that while it is a huge advantage being omnivores, for humans if we don't eat in moderation we can get ill. In particular, obesity, caused by eating too much, and too much of foods that our bodies cannot deal with (fats, sugars etc), is a major health problem for humans.

This week we would like you to think about muscles and skeletons. Below are a series of videos about animals that have bones and muscle structures. We would like you to answer the following questions:

Why do some animals have bones?
How do muscles help animals?

How do muscles and bones work together in the human body?

What would happen if you didn't have muscles and bones? How could you move? Remember, some animals don't have muscles and bones!
