Mass and Weight - Free Printable

Here's the completed worksheet with explanations for each answer:

---

1. On Earth, the astronaut’s weight is _greater than_ her weight on the Moon.

✔ Explanation:
The text says: *“Earth’s gravity pulls on the astronaut”* and *“The moon’s gravity pulls less strongly on the astronaut.”*
Since weight is the force of gravity acting on mass, and Earth’s gravity is stronger than the Moon’s, the astronaut weighs more on Earth.

---

2. On the Moon, the astronaut’s mass is _the same as_ her mass on Earth.

✔ Explanation:
The text clearly states: *“Mass does not change unless you add matter or take away matter.”*
The astronaut hasn’t gained or lost any matter by going to the Moon — only the gravitational force (weight) changes. So her mass stays the same.

*(Note: The question says “her weight on Earth” — this appears to be a typo. It should say “her mass on Earth.” Based on context and science, we assume it meant to compare mass to mass.)*

3. The astronaut’s volume on Earth is _the same as_ her volume on the Moon.

✔ Explanation:
Volume is the amount of space an object takes up. Unless the astronaut is squished or expanded (which doesn’t happen in space travel), her physical size — and therefore volume — remains unchanged whether she’s on Earth or the Moon.

---

4. The astronaut has _the same_ amount of matter on the Earth and on the Moon.

✔ Explanation:
Mass measures the amount of matter in an object. Since mass doesn’t change with location (as explained in the text), the amount of matter in the astronaut is identical on both Earth and the Moon.

---

5. The astronaut _is_ made of matter.

✔ Explanation:
The very first sentence of the text says: *“Everything is made of matter.”*
Since the astronaut is a physical being, she is made of matter.

---

✔ Final Answers:

1. greater than
2. the same as *(assuming typo — comparing mass to mass)*
3. the same as
4. the same
5. is
