Why Does Matter Matter? - Century Life Science - Free Printable

Actually, you did not upload an image — you pasted the *text content* of a worksheet titled “Why Does Matter Matter?” by Kelly Hashway.

Since there’s no actual image to analyze (like a diagram, chart, or picture-based question), I’ll solve and explain the educational content of this worksheet as if it were a reading comprehension and science concept exercise.

## ✔ Problem Solved: Understanding States of Matter

The “problem” here is to understand what matter is, and how solids and liquids differ based on their atomic structure and observable properties.

---

## 🧠 EXPLANATION OF THE SOLUTION

1. What is Matter?

> *“Everything found on Earth can be grouped into one of three states of matter: solid, liquid, or gas.”*

- Matter = anything that has mass and takes up space.
- Trees, air, water — all have mass and volume → they are matter.
- We classify matter into 3 main states: solid, liquid, gas (gas isn’t covered in detail here).

---

2. Key Properties Used to Identify States of Matter

To figure out which state an object is in, we look at:
- Shape → Does it keep its own shape?
- Mass → How much matter it contains (measured in grams, kg, etc.)
- Volume → How much space it takes up (measured in mL, L, cm³, etc.)

> 💡 Note: Mass and volume are shared by all states of matter. Shape is what helps us distinguish them.

3. Solids — Defined Shape & Structure

#### ✔ Characteristics:
- Definite shape → doesn’t change unless forced.
- Definite mass and volume.
- Atoms are packed tightly together and bonded → they vibrate but don’t move around.
- Examples: trees, TVs, beds, chairs, food.

#### 🔬 Atomic View (from the worksheet):
> *“The atoms in a solid are packed closely together. They bond together and do not change shape.”*

➡️ This explains why solids hold their form — atoms are locked in place.

---

4. Liquids — No Fixed Shape, Flows

#### ✔ Characteristics:
- No definite shape → takes the shape of its container.
- Has definite mass and volume.
- Atoms are close together but can slide past each other → allows flow.
- Examples: spilled milk, water in a glass, juice in a bottle.

#### 🔬 Atomic View (from the worksheet):
> *“The atoms in a liquid are close together. They slide around.”*

➡️ This explains why liquids pour and spread — atoms are mobile but still attracted to each other.

---

5. Real-Life Example from Worksheet

> *“If you’ve ever spilled a glass of milk, then you know it spreads out across the floor.”*

- Why? Because milk is a liquid → no fixed shape → flows to fill the space it’s in.
- Same amount of milk looks different in a tall glass vs. wide mug → because it adapts to the container.

---

## 🎯 Summary Answer (as if answering a test question):

> Matter matters because everything we see and touch is made of it — it has mass and takes up space. Solids and liquids are two states of matter that differ mainly in shape. Solids have a fixed shape because their atoms are tightly bonded and don’t move. Liquids take the shape of their container because their atoms can slide past each other. Both have mass and volume, but only solids keep their own shape.

## 📝 Optional Student Activity (if this were a classroom assignment)

You could be asked to:

✔ Draw and label a solid and a liquid with arrows showing atom movement.

✔ List 3 examples of solids and 3 examples of liquids from your home.

✔ Explain why ice (solid) melts into water (liquid) — hint: heat gives atoms energy to break bonds!

---

## 🏁 Final Thought

This worksheet teaches foundational science concepts using everyday examples. Understanding states of matter helps students later learn about gases, changes of state (melting, freezing), and even chemistry and physics.

Let me know if you want a printable version, quiz questions, or to add the gas state to this lesson! 🌬️💧🌲

✔ Problem solved! You now understand the science behind “Why Does Matter Matter?” — and how solids and liquids differ at the atomic level.
