This worksheet helps students review key concepts like mass, volume, and density through a simple matching activity.

Let's solve this worksheet step by step. The goal is to match each question on the left with the correct answer on the right.

🔹 Step 1: Understand the Questions and Possible Answers

Here are the questions (left side) and the answer choices (right side):

Questions:
1. What is Matter?
2. How are mass and volume alike?
3. Name a unit used to measure mass
4. Which property of matter changes depending on the gravitational pull?
5. What determines an object's ability to float?
6. What is density?

Answer Choices:
- weight
- the measure of how light or heavy something is for its size
- density
- the mass and volume of an object never change
- grams, ounces, pounds, tons
- anything that has both mass and volume

---

🔹 Step 2: Match Each Question to the Correct Answer

#### 1. What is Matter?
> ✔ Answer: *anything that has both mass and volume*
This is the definition of matter.

➡️ Match: "What is Matter?" → "anything that has both mass and volume"

---

#### 2. How are mass and volume alike?
> ✔ Answer: *the mass and volume of an object never change*
Mass and volume are both intrinsic properties — they do not change with location or gravity (unlike weight). They remain constant unless the object is altered.

➡️ Match: "How are mass and volume alike?" → "the mass and volume of an object never change"

---

#### 3. Name a unit used to measure mass
> ✔ Answer: *grams, ounces, pounds, tons*
These are all units of mass (though pounds and ounces are also sometimes associated with weight, they are commonly used as mass units in everyday contexts).

➡️ Match: "Name a unit used to measure mass" → "grams, ounces, pounds, tons"

---

#### 4. Which property of matter changes depending on the gravitational pull?
> ✔ Answer: *weight*
Weight is the force of gravity acting on mass. It changes with location (e.g., on Earth vs. Moon), while mass stays the same.

➡️ Match: "Which property... changes with gravity?" → "weight"

---

#### 5. What determines an object's ability to float?
> ✔ Answer: *the measure of how light or heavy something is for its size*
This describes density. An object floats if its density is less than the fluid it's in (e.g., water).

➡️ Match: "What determines floating?" → "the measure of how light or heavy something is for its size"

> Note: This phrase is a description of density, so it matches with the concept of density.

---

#### 6. What is density?
> ✔ Answer: *the measure of how light or heavy something is for its size*
This is a simple definition of density: mass per unit volume.

➡️ Wait! We already used this answer for #5.

But look closely — "the measure of how light or heavy something is for its size" appears twice in the list? No, actually:

Wait — let's recheck the answer options:

The right column has:
1. weight
2. the measure of how light or heavy something is for its size
3. density
4. the mass and volume of an object never change
5. grams, ounces, pounds, tons
6. anything that has both mass and volume

So "the measure of how light or heavy..." is one unique option.

And "density" is another.

So for #5: What determines floating? → Density → but the definition is given as "the measure of how light or heavy..."

So we need to match:
- "What determines floating?" → "density"
- "What is density?" → "the measure of how light or heavy something is for its size"

Ah! That’s the key.

Let’s fix the matching:

✔ Final Correct Matches:

| Question | Answer |
|--------|--------|
| What is Matter? | anything that has both mass and volume |
| How are mass and volume alike? | the mass and volume of an object never change |
| Name a unit used to measure mass | grams, ounces, pounds, tons |
| Which property of matter changes depending on the gravitational pull? | weight |
| What determines an object's ability to float? | density |
| What is density? | the measure of how light or heavy something is for its size |

📝 Bonus: Describe the properties of matter of an object in your classroom.

Example Answer:
A book in my classroom has mass and takes up space, so it is matter. Its mass is about 500 grams, and its volume is around 300 cubic centimeters. It has a density of about 1.67 g/cm³. The book does not float in water because its density is greater than water’s. Its weight would be different on the Moon, but its mass stays the same.

✔ Summary of Matching:

- What is Matter? → anything that has both mass and volume
- How are mass and volume alike? → the mass and volume of an object never change
- Name a unit used to measure mass → grams, ounces, pounds, tons
- Which property changes with gravity? → weight
- What determines floating? → density
- What is density? → the measure of how light or heavy something is for its size
