Science worksheet to label parts of the human ear.

Let’s solve this step by step.

We are given a diagram of the human ear with 8 numbered parts, and we need to match each number to the correct part from the word bank:

Word Bank:
Malleus, Incus, Stapes, Pinna, Auditory canal, Cochlea, Eardrum, Semi-circular canals

Step 1: Look at part #1 — it’s pointing to the outermost visible part of the ear (the flap you can see on the side of your head). That’s called the Pinna.

Step 2: Part #2 — this is the tube that leads from the outside into the middle ear. It’s the passage sound travels through. That’s the Auditory canal.

Step 3: Part #3 — this is one of the tiny bones in the middle ear. The first bone after the eardrum is the Malleus (also called the hammer).

Step 4: Part #4 — this is the second tiny bone, connected to the malleus. That’s the Incus (anvil).

Step 5: Part #5 — this is the third tiny bone, smallest one, connected to the incus and leading to the inner ear. That’s the Stapes (stirrup).

Wait — actually, looking again: part #5 is pointing to the spiral-shaped structure inside the inner ear. That’s not the stapes — that’s the Cochlea. So let’s correct:

Actually, let’s reassign carefully based on standard ear anatomy diagrams:

Standard labeling:
- Outer ear: Pinna → Auditory canal → Eardrum
- Middle ear: Malleus → Incus → Stapes
- Inner ear: Cochlea + Semi-circular canals

Looking at the diagram:

#1 → outer flap → Pinna

#2 → tube going inward → Auditory canal

#7 → thin membrane at end of auditory canal → Eardrum

#6 → small bone attached to eardrum → Malleus

#3 → next bone → Incus

#4 → last tiny bone → Stapes

#5 → spiral shape → Cochlea

#8 → looped structures above cochlea → Semi-circular canals

Yes, that matches standard anatomy.

So final matching:

1. Pinna
2. Auditory canal
3. Incus
4. Stapes
5. Cochlea
6. Malleus
7. Eardrum
8. Semi-circular canals

Double-checking:

- Pinna = outer ear flap ✔️
- Auditory canal = tube ✔️
- Eardrum = membrane at end of canal ✔️
- Malleus = first bone ✔️
- Incus = second bone ✔️
- Stapes = third bone ✔️
- Cochlea = spiral for hearing ✔️
- Semi-circular canals = balance loops ✔️

All match!

Final Answer:
1. Pinna
2. Auditory canal
3. Incus
4. Stapes
5. Cochlea
6. Malleus
7. Eardrum
8. Semi-circular canals
