This half-term in Science, Year 4 are biologists and will be learning all about living things and their habitats.
Biology is the study of living things.
We’ve been grouping and classifying animals and have used classification keys to help us do so.
All animals can be classified as either vertebrates (animals with a spine) or invertebrates (animals without a spine).
There are five types of vertebrates that we’ve explored:
- mammals
- birds
- fish
- reptiles
- amphibians
A classification key helps scientists identify things using closed questions (‘yes’ or ‘no’). We’ve been using classification keys to classify a variety of vertebrates and invertebrates.
We’ve discussed what makes a good classification key question. For example, ‘Is it scary?’ isn’t useful because people find different things scary which could lead to misclassified animals. Instead, our questions should be simple, observable and objective. Your children had a chance to write their own…
