The Nervous System Natural Science worksheet - Free Printable

Let's solve the problem step by step.

1. Label the image about the brain

We are given three parts of the brain to label:
- Cerebrum
- Cerebellum
- Brain Stem

And we have a diagram with three colored regions:

- Blue (top) – This is the largest part of the brain, responsible for thinking, memory, and voluntary actions.
→ Cerebrum

- Yellow (back, below the cerebrum) – This is the smaller, folded structure at the back of the brain that helps with coordination and balance.
→ Cerebellum

- Red (bottom, stem-like) – This connects the brain to the spinal cord and controls basic life functions like breathing and heart rate.
→ Brain Stem

So, the labels should be:

- Blue box (top) → Cerebrum
- Yellow box (middle-right) → Cerebellum
- Red box (bottom-left) → Brain Stem

✔ Correct labeling:

- Blue region: Cerebrum
- Yellow region: Cerebellum
- Red region: Brain Stem

2. Match the parts of the brain with their correct action

We are given statements on the left and brain parts on the right. We need to match them correctly.

#### Given:
a. This part controls voluntary actions
b. This part controls involuntary actions
c. This part controls our coordination and balance
d. The brain controls our nervous system

#### Options:
- Brain stem
- Cerebellum
- Cerebrum
- Nervous system

Now let’s match each:

---

a. This part controls voluntary actions → Cerebrum
✔️ The cerebrum is responsible for conscious thought, decision-making, and voluntary movements.

b. This part controls involuntary actions → Brain stem
✔️ The brain stem regulates automatic functions like breathing, heartbeat, and blood pressure.

c. This part controls our coordination and balance → Cerebellum
✔️ The cerebellum fine-tunes motor movements, maintains balance, and coordinates muscle activity.

d. The brain controls our → Nervous system
✔️ The brain is the central control center of the nervous system, so it controls it.

Wait — this one is tricky. Let's read carefully:

> d. The brain controls our _______

The blank should be filled with "nervous system", because the brain is part of the nervous system and acts as its control center.

But in the matching, it says:

> d. The brain controls our
> → Nervous system

So yes, this is correct: The brain controls our nervous system.

But note: the "nervous system" is not a part of the brain — it's the whole system including the brain and spinal cord. But in this context, it's likely meant as a general statement.

So final matches:

| Statement | Correct Match |
|---------|---------------|
| a. Controls voluntary actions | Cerebrum |
| b. Controls involuntary actions | Brain stem |
| c. Controls coordination and balance | Cerebellum |
| d. The brain controls our | Nervous system |

✔ Final Answers:

#### 1. Labeling the brain:
- Blue area (top) → Cerebrum
- Yellow area (back) → Cerebellum
- Red area (bottom) → Brain Stem

#### 2. Matching:
a. Voluntary actions → Cerebrum
b. Involuntary actions → Brain stem
c. Coordination and balance → Cerebellum
d. The brain controls our → Nervous system
