Educational worksheet for labeling parts of the human eye.

To solve this "Cut and Stick" activity, we need to identify the parts of the human eye based on their location in the diagram. Let's look at the larger diagram on the right, as it shows the structure most clearly.

Step-by-Step Identification:

1. Front of the Eye (Right Side):
* The clear, curved outer layer at the very front is the Cornea. It lets light in.
* Behind the cornea is the colored part called the Iris. It controls how much light enters.
* The hole in the center of the iris is the Pupil.
* Behind the pupil is a clear lens that focuses light. This is the Lens.

2. Back of the Eye (Left Side):
* The large space inside the eye is filled with a jelly-like substance called the Vitreous Humour (or Vitreous Body). It helps keep the eye's shape.
* The layer lining the back of the eye is the Retina. This is where images are formed.
* The bundle of nerves at the very back that sends signals to the brain is the Optic Nerve.

3. Middle Layer:
* There is a layer between the white outer part and the inner retina. In many diagrams, this middle vascular layer is labeled as the Choroid. Looking at the lines on the left side of the diagram:
* The top line points to the outer white layer -> Sclera.
* The bottom line points to the layer just inside the sclera -> Choroid.
* *(Note: Depending on the specific word bank provided in your worksheet, the labels might vary slightly, but these are the standard anatomical terms. Common labels for school worksheets usually include: Cornea, Iris, Pupil, Lens, Retina, Optic Nerve, Sclera, and Vitreous Humour/Body.)*

Let's match the boxes to the likely labels found in the word bank at the bottom of the first page (which appears to list: *lens, iris, pupil, sclera, cornea, optic nerve, retina, vitreous humour*).

Matching the Boxes (Right Diagram):

* Top Right Box: Points to the clear front surface. -> Cornea
* Middle Right Box (top): Points to the colored ring. -> Iris
* Middle Right Box (bottom): Points to the gap in the center. -> Pupil
* Bottom Right Box: Points to the oval structure behind the pupil. -> Lens
* Bottom Left Box: Points to the nerve exiting the back. -> Optic Nerve
* Top Left Box: Points to the tough outer white coat. -> Sclera
* Middle Left Box (lower one pointing to the back wall): Points to the light-sensitive layer at the back. -> Retina
* Middle Left Box (upper one pointing to the middle jelly): Points to the jelly filling the eye. -> Vitreous Humour

*(Self-Correction/Refinement: Let's double-check the lines on the left side of the right-hand diagram.
- The top-left line points to the outermost layer at the back/side. That is the Sclera.
- The bottom-left line points to the nerve stalk. That is the Optic Nerve.
- Wait, looking closely at the right diagram again:
- Top Right: Cornea
- Middle Right (upper): Iris
- Middle Right (lower): Pupil
- Bottom Right: Lens
- Bottom Left: Optic Nerve
- Top Left: Sclera (outer layer)
- There are two boxes on the left side pointing into the eye cavity/back wall.
- One points to the inner lining at the back: Retina.
- One points to the large central space: Vitreous Humour.
- There is one box on the far left pointing to the outer layer? No, let's trace carefully.

Let's re-trace the 8 boxes on the main diagram:
1. Top Right: Points to the front curve. Cornea.
2. Right Side (upper): Points to the iris structure. Iris.
3. Right Side (lower): Points to the pupil opening. Pupil.
4. Bottom Right: Points to the lens. Lens.
5. Bottom Left: Points to the nerve. Optic Nerve.
6. Left Side (lower/middle): Points to the back inner wall. Retina.
7. Left Side (upper/middle): Points to the jelly inside. Vitreous Humour.
8. Top Left: Points to the outer white layer. Sclera.

This covers all 8 standard parts usually taught at this level.

Final Answer:
Here are the correct labels for the parts of the eye, matching the positions in the diagram:

Right Side (Front of the Eye):
* Top box: Cornea
* Upper middle box: Iris
* Lower middle box: Pupil
* Bottom box: Lens

Left Side (Back of the Eye):
* Top box: Sclera
* Upper middle box: Vitreous Humour (or Vitreous Body)
* Lower middle box: Retina
* Bottom box: Optic Nerve
