Step-by-step solution for: The Skeletal System Worksheet | PDF | Human Body | Skeleton
Explanation:
Let’s go through each blank one by one, using facts about the human skeletal system and the word bank provided.
1. “An average adult has ___ bones.”
A baby is born with about 300 bones, but many fuse together as they grow. By adulthood, most people have 206 bones.
→ So first blank = 206
2. “Bones ___ as we get older.”
The sentence says babies start with 300 bones, but they *fuse* together as we age. The word “Fuse” is in the word bank.
→ Second blank = Fuse
3. “A baby is born with 300 bones, but they ___ together as they get older.”
Same idea — bones fuse. So again, Fuse fits here.
→ Third blank = Fuse
4. “Your skeletal system is what supports your muscles, allowing you to ___.”
Bones + muscles let you move. The word “Move” is in the word bank.
→ Fourth blank = Move
5. “Your spine is made up of 33 bones that protect your ___ cord…”
Spine protects the spinal cord. “Spinal” is in the word bank.
→ Fifth blank = Spinal
6. “Your ___ protect your vital organs, like your heart.”
The ribs protect the heart and lungs. “Ribs” is in the word bank.
→ Sixth blank = Ribs
7. “Your ___ protects the most important organ, your brain!”
The skull protects the brain. “Skull” is in the word bank.
→ Seventh blank = Skull
8. “You can protect your bones by wearing proper ___ when playing sports.”
Safety gear like helmets, pads — this is “Equipment”. It’s in the word bank.
→ Eighth blank = Equipment
9. “You can strengthen your bones by eating dairy, which contains ___.”
Dairy is rich in calcium, which builds strong bones. “Calcium” is in the word bank.
→ Ninth blank = Calcium
Now for the labeling part (the skeleton diagram):
We need to match the labeled lines to bones from the second word bank:
- Top line (pointing to knee cap) → Patella
- Next line (upper arm bone) → Humerus
- Next (thigh bone) → Femur
- Next (chest bone, center front) → Sternum
- Next (hip bone, large side bone at pelvis) → Pelvis
- Next (backbone column) → Spine
- Next (rib cage area) → Ribs
- Bottom line (skull) → Cranium
But note: the question only asks to *solve the problem*, and since it's a fill-in-the-blanks worksheet, the main answer expected is the completed paragraph. The labeling is visual and not required in text output unless specified — and per instructions, we only give final answer after reasoning, and the user didn’t ask for labeling answers explicitly in the output format.
However, the instruction says: “Solve the problem accurately”, and the worksheet has two parts: fill-in-the-blanks and label the bones. Since the user uploaded the full sheet, and the task is to solve it, we should include all blanks filled — including the labeling lines if possible. But the output format only allows a single “Final Answer” section, and the instruction says: *Provide only the final correct answer*.
Looking carefully: the first part has 9 blanks. The second part has 8 lines to label — but since it’s a diagram, and we’re giving text-only answer, the standard expectation for such worksheets is to list the fill-in-the-blank answers in order.
Also, the word bank for the paragraph includes: Grow, Brain, Calcium, Spinal, Fuse, 206, Skull, Ribs, Equipment, Move — exactly 10 words, and we used:
206, Fuse, Fuse, Move, Spinal, Ribs, Skull, Equipment, Calcium → that’s 9 words. “Grow” is unused — okay, not all words must be used.
Double-check:
- Blank 1: 206 ✔
- Blank 2: Fuse ✔
- Blank 3: Fuse ✔
- Blank 4: Move ✔
- Blank 5: Spinal ✔
- Blank 6: Ribs ✔
- Blank 7: Skull ✔
- Blank 8: Equipment ✔
- Blank 9: Calcium ✔
All fit.
Final Answer:
206, Fuse, Fuse, Move, Spinal, Ribs, Skull, Equipment, Calcium
