Science: Variation and Classification

Is it alive?

Then its either a plant or an animal!

Scientists divide different plants and animals into smaller groups to identify the. They look for differences and similarities to the help decide on which groups to put them in.

ANIMAL groups = Vertebrates (backbone) vs. Invertebrates (no backbone)

Vertebrates = Fish, amphibians, reptiles, birds, mammals
Invertarates = insects, arachnids, molluscs

PLANT groups = Flowering vs non-flowering

Flowering = frasses, cereals, garden shrubs, deciduous trees
Non-flowering = algae, fungi, ferns, coniferous trees

Have a look at http://www.crickweb.co.uk/ks1science.html#groupinganimals for some interactive practice.
