Living things & their habitats

Group organisms

Now we know what's alive — how do scientists sort living things into groups by their features?

Whiteboard task as you come in — a look back at last lesson: conditions for life.

Recap: is it alive?

🌱 Seedling
Working towards

Circle the living things:

rock · dog · car · tree · flame

MRS GREN: what does the M stand for?

🌿 Sapling
Expected
  1. Give two of the seven life processes.
  2. Why is a car not alive?
  3. How does a plant “move”?
🌳 Oak
Greater depth

Prove a mushroom is alive. Give three pieces of evidence using MRS GREN.

Bridge into todayWe can spot a living thing. But there are millions of them! Today we start sorting them into groups — the job scientists call classifying.
Starter 5 min

Show the animals. Pupils find ways to group them at their tier.

How would you group them?

🐕 dog   🦈 shark   🦅 eagle   🐸 frog   🐍 snake   🐝 bee   🕷️ spider   🐌 snail

🌱 Seedling
Working towards

Put them into two groups: has legs / no legs.

🌿 Sapling
Expected

Find at least two different ways to group them (legs, wings, where they live…). Name your rule each time.

🌳 Oak
Greater depth

Find one rule that would split every animal into two groups — even ones not shown here. What's your rule?

The big block question🧭 How can animals, plants and microorganisms be identified, grouped and classified? That's what this whole block is about.

Teacher models. Watch, then unpack the animal groups.

Backbone or not? Vertebrates & invertebrates

▶ Can't see it? Watch “Vertebrates & Invertebrates” on YouTube

Swap the clip: change the ID after /embed/ (now mRidGna-V4E).

Say thisThe first big split for animals: does it have a backbone? Vertebrate = has a backbone. Invertebrate = no backbone. Vertebrates split into five groups.
🦊
Mammalsfur; feed young milk
🐦
Birdsfeathers; beak; eggs
🐟
Fishscales; gills; water
🐸
Amphibiansmoist skin; land & water
🦎
Reptilesdry scaly skin; eggs
We do · 1 6 min

Together — first backbone or not, then which vertebrate group.

Sort the animals with me

🦈 shark   🐈 cat   🐦 robin   🐸 frog   🐍 snake   🐝 bee

Two questions each time
1) Does it have a backbone?   2) If yes — which of the five groups, and what's the clue?
Example: “The robin is a vertebrate because it has a backbone. It's a bird because it has feathers and a beak.”

Bust the myths, then group the plants.

Plants split too — and a whale is no fish

Whales come up to breathe air — that makes them mammals, not fish!

Model the mythsNot every sea animal is a fish — a whale is a mammal (it breathes air). And not every plant has flowers.

🌸 Flowering plants

Make flowers, fruit and seeds. E.g. rose, daisy, apple tree.

🌿 Non-flowering

No flowers — make spores instead. E.g. fern, moss.

Invertebrate groups to know: insects (6 legs), arachnids (8 legs), molluscs (soft body).

We do · 2 5 min

Group the plants together, then a quick invertebrate check.

Flowering or non-flowering?

🌹 rose   🌿 fern   🌼 daisy   🍏 apple blossom   🌱 moss   🌻 sunflower

Say it like a scientist
“A fern is a non-flowering plant because it makes spores, not flowers.”
Then group these invertebrates: 🐝 bee (insect) · 🕷️ spider (arachnid) · 🐌 snail (mollusc).
Independent 10 min

On your own. Sort every organism, then write your evidence at your tier.

The Grouping Sorter

🦴 Vertebrate

🐛 Invertebrate

🌿 Plant

Tap an organism to sort it…

🌱 Seedling
Working towards

Sort the animals into vertebrate / invertebrate. Then finish:

“A ____ is a vertebrate because it has a ____.”  
Word bank: backbone (spine)
🌿 Sapling
Expected

Sort all three bins. Write for one animal its group and a feature:

“A robin is a bird because it has feathers and a beak.”
🌳 Oak

Sort all, then pick two vertebrates from different groups and explain the feature that tells them apart. And: why is a whale not a fish?

Answer at your tier, then hand it in on the way out.

Show what you know

🌱 Seedling
Working towards
  • Tick the vertebrates: dog · spider · fish · snail · bird
  • Fill the gap: “An animal with a backbone is a ____.”
  • Circle the flowering plant: fern · rose · moss
🌿 Sapling
Expected
  1. Name the five vertebrate groups.
  2. Give one feature of mammals.
  3. Is a whale a fish? Explain.
🌳 Oak

A friend says “a spider is an insect.” Are they right? Use features (legs, body parts) to explain.

🧭 Coming nextWe can group organisms by their features. Next lesson we turn that into a proper tool — a classification key.
TA Focus · Group organisms
Traps to watch

“All sea animals are fish” (whale = mammal, breathes air). “All plants have flowers” (ferns, moss don't). Soft body ≠ invertebrate automatically — it's the backbone that decides.

Tier steer
Always

Backbone is the deciding feature — not size, shape or where it lives.
