Classification

Enjoyable Quiz for Children Aged 7 to 11

This KS2 Science quiz takes a look at classification. This is the grouping together of similar species of plant, animal and other organisms.

Classification means to group similar species together. There are millions of different species living on our planet - different types of plants, animals, fungi, and bacteria.. In order to learn more about them, it is necessary for scientists to sort them into groups. Related species can be compared by their similarities and differences. You have most likely been asked to classify a group of organisms during one of your science lessons.

How good are you at grouping animal and plant species? Do you know the difference between a fish and a whale or an invertebrate and a vertebrate? See how much you know about classification by trying this science quiz on the topic.

The plant kingdom is divided into two important groups. What are they?

Grasses and trees

Green plants and non-green plants

Flowering and non-flowering plants

Coniferous and deciduous plants

Non-flowering plants include algae, lichens, ferns and mosses. These plants produce spores rather than seeds

What is an invertebrate?

An animal with wings

An animal with six legs

An animal without a spine

An animal which lays eggs

An animal with a spine is a vertebrate

Vertebrates are divided into five classes (groups). Which one of the following is not a class of vertebrates?

Mammals

Marsupials

Reptiles

Amphibians

Marsupials, such as kangaroos, are mammals

If you were creating a classification key for sea animals, which question would separate dolphins from sharks?

Does the animal have eyes?

Is the animal a vertebrate?

Does the animal breathe through gills?

Is the animal a carnivore?

Dolphins must come to the surface of the water in order to breathe air, while sharks use their gills to breathe underwater. This is because dolphins are mammals, while sharks are fish

Which class of animals is warm-blooded?

Birds

Amphibians

Reptiles

Fish

Mammals are also warm-blooded, of course!

What uses a series of questions in order to identify unknown plants or animals?

Classification index

Bar chart

Comparison table

Classification key

A classification key can also be called an identification key. The questions use the similarities and differences between organisms to identify them

If you were creating a classification key for invertebrates, which question would distinguish between a spider and an ant?

Does the animal have an exoskeleton?

Does the animal have wings?

Does the animal have six legs?

Does the animal bear live young?

Although a small number of ants do have wings, most do not. The number of legs is the best difference between a spider and an ant

What does classification mean?

Grouping similar organisms together

Observing living organisms under a microscope

Randomly grouping living organisms in order to investigate their characteristics

Creating a classroom display of the results of an investigation

For example, all animals with feathers or all plants with flowers

Which of the following is not an invertebrate?

A spider

A millipede

An octopus

A snake

Snakes are vertebrates because they have a spine. Invertebrates are divided into many groups. The largest group is the arthropods, which includes insects, arachnids and crustaceans. Molluscs, such as the octopus, are also invertebrates

10.

If you were creating a classification key for a group of animals found on an island, which question would not separate turtles and birds?

Does the animal have feathers?

Does the animal lay eggs?

Does the animal have a shell?

Is the animal warm-blooded?

Turtles (which are reptiles) and birds both lay eggs
