Let’s go through each question one by one and think carefully to find the right answers.

Question 1: Machines make our lives _______ and _______.
Machines help us do things faster, easier, or with less effort. So they make our lives
easier and
better (or sometimes “faster” — but “easier” is most common in school lessons). Let’s pick two simple words that fit:
→
easier and
better
*(Note: Some might say “faster” instead of “better”, but both are acceptable. We’ll go with the most common pair used in elementary science.)*

Question 2: Simple machines have _______ parts.
Simple machines are basic tools like levers, wheels, pulleys — they don’t have many moving pieces. In fact, they usually have just
one part or very few parts working together. The standard answer taught in schools is:
→
few
So: Simple machines have
few parts.

Question 3: Which one is an example of a lever?
We’re shown three pictures:
- Seesaw
- Slide
- Swing
A
lever is a rigid bar that pivots on a point called a fulcrum. A seesaw is a perfect example — it’s a long board balanced on a triangle (fulcrum), and kids sit on either end to lift each other up. That’s exactly how a lever works.
Slide? No — that’s an inclined plane.
Swing? It moves back and forth, but it’s not a lever — it’s more like a pendulum.
✔ Correct answer:
Seesaw
---
Question 4: Which one is an example of a wheel?
Options:
- Bicycle
- Tablet
- Seesaw
A
wheel is a circular object that rotates around an axle. Bicycles have wheels — big round ones that let you roll forward easily.
Tablet? Flat screen — no wheels.
Seesaw? Already we know it’s a lever — no wheels involved.
✔ Correct answer:
Bicycle
---
Now let’s double-check all answers for accuracy:
1. Machines make our lives →
easier and
better ✔
2. Simple machines have →
few parts
✔
3. Example of a lever →
Seesaw ✔
4. Example of a wheel →
Bicycle ✔
All match what’s taught in elementary science about simple machines.

Final Answer:
1) easier, better
2) few
3) Seesaw
4) Bicycle
