All content is curated for ages 4 and up. Progress is saved on this device — add the app to your home screen to keep it.

Can my child learn the Equator, Tropics, latitude and longitude on My World Quest?

Yes — the World Lines page at https://myworld.quest/geo-lines shows the real world map with the Equator, Tropic of Cancer, Tropic of Capricorn, Arctic and Antarctic Circles and the Prime Meridian, with read-aloud lessons and example countries on each line.

Does My World Quest work offline?

Mostly, yes. It is an installable Progressive Web App: games, puzzles, the globe, country cards and any lessons you have already opened keep working without internet on Android, iOS, Windows, macOS and ChromeOS. Features that need a connection: Ask the Globe and other AI helpers, Live Today sessions, new lessons or practice questions not yet opened, and search.

Does My World Quest collect data on my child?

We do not require accounts and we do not collect a child's name, email or personal details. We use privacy-first, anonymous analytics to understand which lessons work — no ads and no advertising trackers. Progress is stored locally on the device.

Sort It Your Way: How We Group Living Things — Science

Sort It Your Way: How We Group Living Things

1 of 4

For grown-ups

Companion summary

Imagine walking into a forest — how many different ways could you sort every creature you spot? Scientists, doctors, and conservationists all rely on grouping living things to track diseases, protect species, and discover new medicines. Surprisingly, sharks are more closely related to humans than they are to salmon, depending on which features you compare. When you finish, try sorting ten animals by an unexpected feature — like whether they sleep during the day — and see what groups appear.

The Sorting Challenge

Imagine you tip a bag of mixed objects onto a table — coins, buttons, and marbles. Your friend sorts them by colour. You sort them by size. Your teacher sorts them by material. All three of you are right. Nobody made a mistake. Now ask yourself: could the same thing happen with living creatures? Before you read on, think of three animals. Jot down one feature each animal has. Could you sort your three animals in more than one way using those features?

💭 Think about this

Think of a robin, a salmon, and a frog. Write down two features you could use to sort them. Would different features give you different groups?

Why Grouping Depends on the Feature You Choose

Scientists sort living things into groups to make them easier to study and compare. This process is called . The features or traits used to sort organisms are called s — things like body covering, number of legs, method of reproduction, or whether the makes its own food. Here is the key idea: the groups you end up with depend entirely on which characteristic you choose. There is no single 'correct' way to sort living things. Every valid classification is based on real, observable evidence — it just highlights a different aspect of life. Consider these six organisms: oak tree, mushroom, shark, eagle, earthworm, rose bush. Sort by 'can photosynthesise' (makes food using sunlight): Group A — oak tree, rose bush. Group B — mushroom, shark, eagle, earthworm. Sort by 'has a backbone': Group A — shark, eagle. Group B — oak tree, mushroom, earthworm, rose bush. Sort by 'reproduces using spores': Group A — mushroom. Group B — oak tree, shark, eagle, earthworm, rose bush. Notice that the mushroom ended up in different groups each time. The mushroom did not change — the characteristic we looked at changed. This shows that classification is a tool, not a fixed label. Scientists who study how organisms are related — called s — choose characteristics that reflect shared ancestry. But in everyday science, and in this lesson, any well-reasoned feature produces a legitimate grouping. What matters is that you state clearly which feature you used and apply it consistently to every organism.

Worked example

Worked example — sorting four organisms two different ways: Organisms: ladybird, dolphin, sunflower, pine tree. Round 1 — Sort by 'has legs': Legs → ladybird (six legs). No legs → dolphin, sunflower, pine tree. Round 2 — Sort by 'produces seeds': Produces seeds → sunflower, pine tree. Does not produce seeds → ladybird, dolphin. Result: The sunflower and pine tree were in different groups in Round 1 but the same group in Round 2. The ladybird and dolphin were in the same group in Round 1 but different groups in Round 2. Same four organisms, two completely different sorting outcomes — because the characteristic changed.

Test Your Thinking

Try it yourself

Answer each question on your own. Think carefully about which characteristic is being used before choosing your answer.

1. A student sorts a cat, a goldfish, and an oak tree into two groups using the characteristic 'can move from place to place independently'. Which pair ends up in the same group?

2. The same cat, goldfish, and oak tree are now sorted by 'has a backbone'. How does the grouping change?

3. A scientist argues that a mushroom should be classified with plants because both are stationary and found in soil. Another scientist disagrees and sorts them separately because mushrooms cannot photosynthesise. Which statement best describes this situation?

4. You are given five organisms: butterfly, bat, bee, sparrow, and trout. If you sort by 'has wings', which organism is in the group WITHOUT wings?

5. Why is it important to state clearly which characteristic you used when presenting a classification to someone else?

Bring It Together

The groups you create depend entirely on the characteristic you choose — change the characteristic and the groups change.
Every classification based on real, observable evidence is valid; there is no single 'correct' way to sort living things.
Always state which characteristic you used so your reasoning is clear and others can follow your thinking.

1. A class sorted twelve garden organisms into two groups. Group 1 contained snails, beetles, and worms. Group 2 contained daisies, nettles, and grass. Then they re-sorted and the snail moved into a new group alongside the daisies. Which characteristic most likely caused the re-sorting?

🌱 Reflect

Think about the organisms you see on your way to school — birds, insects, trees, or weeds pushing through pavement cracks. Choose two of them and describe two different ways you could sort them. Does either way feel more 'natural' to you, and why might that be?
