States of Matter Worksheet Worksheet for 5th - 8th Grade | Lesson ... - Free Printable

Let’s go through the worksheet step by step to fill in all the blanks correctly.

---

Part 1: Vocabulary Definitions

We’re given a table with columns:
- Symbolism (this seems like a mislabel — probably meant “Term”)
- Definition
- How would you describe this in your own words?
- Real world example

But since the student is expected to fill these out, and we’re solving the numbered questions below, let’s focus on those first.

---

Question 1:
> The amount of matter that makes up something.
→ This is Mass.
✔ Answer: Mass

---

Question 2:
> Anything that has mass and volume is called ________.
→ That’s the definition of Matter.
✔ Answer: Matter

---

Question 3:
> When you add energy to matter, the particles move ________ and the matter ________.
→ Adding energy makes particles move faster → matter expands or changes state (like solid to liquid).
Common answer: faster, expands (or “changes”)
✔ Answer: faster, expands

---

Question 4:
> Particles in a solid are packed so close together they can only ________.
→ In solids, particles vibrate in place.
✔ Answer: vibrate

---

Question 5:
> Particles in a liquid can ________.
→ Liquids flow — particles slide past each other.
✔ Answer: slide past each other (or “flow”)

---

Question 6:
> Particles in a gas are so far apart that they can ________.
→ Gases expand to fill container — particles move freely and spread out.
✔ Answer: move freely (or “spread out”)

---

Question 7:
> When the energy coming from particles they move ________, explains how particles are able to move faster and overcome forces.
→ This is describing heat energy or thermal energy.
✔ Answer: faster (but the blank is likely for the *type* of energy — so heat or thermal energy)
Looking at context: “When the energy coming from particles they move...” — probably meant:
> When heat energy comes from particles, they move faster...
✔ Final Answer: heat

Question 8:
> Match each Term to the left with the best Description on the right. Each Description can be used only once.

Terms:
- Mass
- Solid
- Liquid
- Gas
- Volume
- Matter

Descriptions:
A. Anything that has mass and volume
B. Amount of space that an object takes up
C. Amount of matter in an object
D. Particles are tightly packed and vibrate in place
E. Particles are close but can slide past each other
F. Particles are far apart and move freely

Matching:

- Mass → C (Amount of matter in an object)
- Solid → D (Particles tightly packed, vibrate in place)
- Liquid → E (Close but can slide)
- Gas → F (Far apart, move freely)
- Volume → B (Amount of space)
- Matter → A (Anything with mass and volume)

✔ Correct matches:
- Mass → C
- Solid → D
- Liquid → E
- Gas → F
- Volume → B
- Matter → A

---

Now, compiling all answers:

1. Mass
2. Matter
3. faster, expands
4. vibrate
5. slide past each other (or flow)
6. move freely (or spread out)
7. heat
8. Matching:
- Mass → C
- Solid → D
- Liquid → E
- Gas → F
- Volume → B
- Matter → A

Final Answer:
1. Mass
2. Matter
3. faster, expands
4. vibrate
5. slide past each other
6. move freely
7. heat
8. Mass-C, Solid-D, Liquid-E, Gas-F, Volume-B, Matter-A
