FREE Differentiated Worksheet for the Bill Nye - The Science Guy ... - Free Printable

Let’s go step by step through each question on the worksheet. I’ll think carefully and check my answers before writing them down.

---

1. The force of gravity pulls ______ toward ______.

Gravity pulls objects with mass toward each other. On Earth, we usually say it pulls things “down” — meaning toward the center of the Earth. But in space, gravity pulls planets toward stars, moons toward planets, etc.

So:
→ Gravity pulls objects (or “things”) toward each other (or specifically, “the center of massive bodies like Earth”).

But since this is a basic video guide, they probably want:
“objects” toward “Earth” or “things” toward “the ground”.

Looking at common phrasing in middle school science:
✔ Final choice: objects → Earth

*(Note: Technically correct answer is “masses toward each other,” but for this level, “objects toward Earth” is acceptable.)*

Wait — let’s look ahead. Question 4 says: “The pull of gravity toward the center of ___ is called weight.” So they’re using “center of [planet]”.

Also, question 5: “The greater an object’s ___, the stronger its gravitational pull.” → That’s mass.

Question 6: “Our weight comes from the pull of ___ on us.” → Earth.

So for #1, safest simple answer:
“objects” toward “Earth”

But actually, even better: In many curricula, they say:
“Gravity pulls everything toward the center of the Earth.”

So maybe:
“everything” toward “the center of the Earth”

But the blank is short. Let’s see how many words fit.

Looking at the image layout (even though I can’t describe it), the blanks are likely one or two words.

Common textbook phrase:
“The force of gravity pulls objects toward each other.”

That’s Newton’s law — universal gravitation.

Yes! That’s more accurate and matches later questions about planets and stars.

Check question 7: “All the planets ___ because of the sun’s ___.” → orbit / gravity

So yes — gravity acts between all objects.

✔ Best answer for #1: objects → each other

2. The pull of gravity toward the center of ___ is called weight.

Weight = force of gravity pulling you toward the center of a planet (usually Earth).

So: Earth

(If on Moon, it would be Moon — but default is Earth.)

✔ Answer: Earth

---

3. ___ is a measure of the amount of ___ an object has.

First blank: What measures amount of stuff? → Mass

Second blank: Amount of what? → Matter

Standard definition:
Mass is a measure of the amount of matter in an object.

✔ Answers: Mass → matter

---

4. Weight depends on both ___ and ___ difference in the pull of gravity.

Weight = mass × gravity

So weight depends on:
- Your mass
- The strength of gravity where you are (which depends on location — e.g., Earth vs. Moon)

The phrase says: “difference in the pull of gravity” — so probably comparing places.

So: Weight depends on mass and location (because gravity changes by location).

Some might say “gravity” instead of “location”, but the sentence says “difference in the pull of gravity”, implying location causes that difference.

✔ Answers: mass → location

*(Alternative: “mass” and “gravitational field strength” — too advanced. Stick with “location”.)*

---

5. The greater an object’s ___, the stronger its gravitational pull.

Gravitational pull depends on mass. More mass = stronger gravity.

✔ Answer: mass

---

6. Our weight comes from the pull of ___ on us.

On Earth, our weight is due to Earth’s gravity pulling us.

✔ Answer: Earth

---

7. All the planets ___ because of the sun’s ___.

Planets orbit the Sun because of the Sun’s gravity.

✔ Answers: orbit → gravity

---

8. Without gravity, the planets would ___ off into ___ where as a child plays on a swing.

Without gravity, planets wouldn’t stay in orbit — they’d fly off in straight lines (inertia).

“Fly off into space”

And the swing part: when you let go of a swing, you fly off — same idea.

So:
Planets would fly off into space

✔ Answers: fly → space

---

9. If you jumped up on Jupiter, you would fall back faster than on Earth because of a bigger ___ than the force of ___ on Earth.

Jupiter has stronger gravity than Earth → so you fall faster.

Force of gravity is stronger → so “bigger force of gravity”

Sentence structure:
“because of a bigger ___ than the force of ___ on Earth.”

Probably:
“bigger force of gravity” than the force of gravity on Earth.

But that repeats “force of gravity”.

Maybe:
“bigger pull” than the force of gravity

Or:
“bigger gravitational pull” than the force of gravity

Actually, looking at wording:
“a bigger ___ than the force of ___”

Best fit:
“a bigger force than the force of gravity”

Wait — that doesn’t make sense. Force of what?

Perhaps:
“a bigger gravitational force than the force of gravity” — still awkward.

Another way: Maybe they mean “stronger gravity” — so:

“because of a bigger gravity than the force of gravity” — no.

Let’s read again:
“If you jumped up on Jupiter, you would fall back faster than on Earth because of a bigger ___ than the force of ___ on Earth.”

Ah — perhaps:
“because of a bigger pull than the force of gravity”

Still not great.

Wait — maybe:
“because of a bigger acceleration due to gravity” — too complex.

Think simply:
Jupiter’s gravity is stronger → so the *force* pulling you down is bigger.

So:
“because of a bigger force than the force of gravity” — redundant.

Perhaps the second blank is “Earth’s gravity”?

No — the sentence says “force of ___ on Earth”

Maybe:
“because of a bigger gravitational pull than the force of gravity”

I think the intended answer is:

force → gravity

Meaning: Jupiter exerts a bigger force (of gravity) than the force of gravity on Earth.

Even if slightly redundant, it fits.

✔ Answers: force → gravity

*(Alternative interpretation: “strength” → “gravity” — also possible. But “force” is used in physics context.)*

Let’s go with force and gravity.

10. I press into my chair because ___ is pushing me down.

What pushes you down? Gravity.

✔ Answer: gravity

---

11. I press into my chair because ___ is fighting gravity.

When you sit, your chair pushes up against gravity — that’s the normal force.

But the question says: “___ is fighting gravity”

So what opposes gravity? The chair’s upward push.

In simple terms: the chair

Or my seat

But scientifically: normal force — too advanced.

For kids: the chair

✔ Answer: the chair

---

12. Once I leave the ___ , I am pulled down by gravity.

Leave what? Leave the chair? Leave the ground?

Context: sitting in chair, then standing up or jumping.

Probably: chair

Because previous questions talk about pressing into chair.

✔ Answer: chair

---

13. No matter where on earth you go, gravity remains ___.

Gravity is approximately constant on Earth’s surface — about 9.8 m/s².

It varies slightly (poles vs equator, mountains vs sea level), but for school purposes, we say it’s constant.

So: constant or the same

✔ Answer: constant

*(“unchanging” also works, but “constant” is standard term.)*

---

14. Everything is pulled ___ by gravity.

Downward? Toward center of Earth?

In everyday language: down

Scientifically: toward the center of the Earth

But blank is short — likely down

✔ Answer: down

---

Now, let’s compile all answers clearly.

Final Answer:

1. objects, each other
2. Earth
3. Mass, matter
4. mass, location
5. mass
6. Earth
7. orbit, gravity
8. fly, space
9. force, gravity

12. chair
13. constant
