Keys, kingdoms and scientific names
Lesson page: echoesof.science/school/classification/ages-10-11/ · Pupil worksheet: echoesof.science/school/classification/ages-10-11/print/
Learning aims
- Know that taxonomy classifies living things into a hierarchy from kingdom to species.
- Explain why fungi are a separate kingdom from plants.
- Distinguish vertebrates and invertebrates.
- Write a binomial name correctly and build and test a dichotomous key.
Lesson plan
| Time | Activity |
|---|---|
| 5 min | Starter: how would you sort 1.5 million species? |
| 10 min | Read the text; practise writing scientific names. |
| 20 min | Build a key; swap and test. |
| 5 min | Improve the key. |
| 5 min | Vertebrate or invertebrate? game or quiz. |
Materials for the experiment
- 8–10 pictures of different whole organisms (for example a spider, a beetle, a butterfly, a snail, an earthworm, a frog, a sparrow, a goldfish, a daisy, a mushroom)
- Large sheet of paper
- Pencil and sticky notes
Safety: Use pictures only; no live animals or picked plants are needed.
Common misconceptions
| Pupils may think… | Actually… |
|---|---|
| Fungi are plants because they grow in the ground. | Fungi cannot photosynthesise and are more closely related to animals than to plants. |
| A key can use questions like 'Is it big?' | Good keys use clear, observable features, such as the number of legs. |
| A species has only one name. | It can have several common names but only one scientific name. |
Worksheet answers
- Kingdom, phylum, class, order, family, genus, species.
- Canis lupus (genus with a capital C, species lower case; written in italics when typed). Canis is the genus.
- Any one: a species can have many common names but only one scientific name; scientific names are not confused with something else.
- Accept the group's answer; it should name a vague question and a clearer, observable replacement.
Quiz answers
- What is taxonomy? The science of classifying living things. Taxonomy means 'arrangement law'.[1]
- Which scientist gave his name to our classification system? Carl Linnaeus. It is called the Linnaean system.[1]
- In Canis lupus, what is 'Canis'? The genus. The first part is the genus.[3]
- Why are fungi not in the plant kingdom? They cannot photosynthesise. Fungi absorb food from their surroundings.[5][4]
- About what share of animals are invertebrates? 99%. Most animals have no backbone.[6]
- How many choices does each step of a dichotomous key have? Two. 'Dichotomous' means splitting in two.[7]
