Educational worksheet for labeling parts of the human skeleton.

Let’s go step by step to label the skeleton correctly using the words given:

Words to use:
- thigh bone
- rib
- backbone
- collarbone
- skull
- kneecap
- pelvis

Now, let’s match each word to the correct part of the skeleton based on where the lines point.

1. The line pointing to the head → that’s the skull.
2. The line pointing to the shoulder area (top of chest, near neck) → that’s the collarbone.
3. The line pointing to the long bones in the upper legs → those are the thigh bones.
4. The line pointing to the curved bones around the chest → those are the ribs.
5. The line pointing down the center of the back → that’s the backbone (also called spine).
6. The line pointing to the hip area → that’s the pelvis.
7. The line pointing to the front of the knee → that’s the kneecap.

Now, let’s assign them to the blank boxes based on their positions in the diagram (from top to bottom, left to right as shown):

Top-right box (pointing to head) → skull

Top-left box (pointing to shoulder) → collarbone

Middle-right box (pointing to ribs) → rib

Middle-left box (pointing to backbone) → backbone

Lower-middle right box (pointing to hip/pelvis area) → pelvis

Bottom-left box (pointing to thigh) → thigh bone

Bottom-right box (pointing to knee) → kneecap

Wait — let me double-check the layout from the image description (since I can’t see it but know standard skeleton labeling):

Typical labeling for this kind of worksheet:

- Top right: skull ✔
- Top left: collarbone ✔
- Middle right: rib ✔
- Middle left: backbone ✔
- Lower middle right: pelvis ✔
- Bottom left: thigh bone ✔
- Bottom right: kneecap ✔

Yes, that matches all 7 labels and 7 blanks.

Final Answer:
Starting from top and going clockwise or by position:

- Skull (head)
- Collarbone (shoulder)
- Rib (chest)
- Backbone (spine)
- Pelvis (hips)
- Thigh bone (upper leg)
- Kneecap (knee)

But since the question asks to “label the skeleton using the words below” and there are 7 blanks with arrows, we must list which word goes in which box.

Assuming the boxes are arranged as follows (based on common CGP worksheets):

Box 1 (top right, arrow to head) → skull
Box 2 (top left, arrow to shoulder) → collarbone
Box 3 (middle right, arrow to ribs) → rib
Box 4 (middle left, arrow to spine) → backbone
Box 5 (lower right, arrow to hip) → pelvis
Box 6 (bottom left, arrow to thigh) → thigh bone
Box 7 (bottom right, arrow to knee) → kneecap

All words used exactly once.

Final Answer:
skull, collarbone, rib, backbone, pelvis, thigh bone, kneecap
