Introduction to Matter

States of matter illustration showing solid, liquid and gas

🔬 Part 1: Understanding Matter

1. What is matter? Circle the best definition:

Anything that is important

Anything that takes up space and has mass

Only things we can see

Only solid objects

2. Fill in the blanks about matter:

Matter is anything that takes up __________ and has __________. Everything around us, including the air we breathe, is made of matter.

3. Check all the examples of matter below:

A pencil

Water in a bottle

Air in a balloon

Your thoughts

Ice cubes

Steam from hot water

🧊💧💨 Part 2: States of Matter

4. Match each state of matter with its properties:
1. Solid
2. Liquid
3. Gas
A. Flows and takes the shape of its container
B. Keeps its shape and is rigid
C. Fills the entire container and is often invisible
5. Complete the sentences about states of matter:

A __________ keeps its shape because its particles are tightly packed together.

A __________ flows because its particles can move around each other.

A __________ expands to fill any container because its particles move freely.

6. Circle the state of matter for each example:

Water in a glass: Solid / Liquid / Gas

A wooden table: Solid / Liquid / Gas

The air you breathe: Solid / Liquid / Gas

Ice cream: Solid / Liquid / Gas

Steam from cooking: Solid / Liquid / Gas

📝 Part 3: Classification Activity

7. Look around your classroom. List three examples of each state of matter you can observe:

Solids:

Liquids:

Gases:

8. Choose one example from each category above and explain why it belongs in that state:

Solid example: _________________ because:

Liquid example: _________________ because:

Gas example: _________________ because:

🎨 Part 4: Visual Understanding

9. Draw particles (small circles) to show how they are arranged in each state of matter:

Solid (particles close together, organised):

Liquid (particles close but can move):

Gas (particles far apart, moving freely):

10. Think about matter in Papua New Guinea. Give examples of matter from your local environment:

Solid from nature: _________________________

Liquid from nature: _________________________

Gas in our atmosphere: _________________________

🤔 Part 5: Critical Thinking

11. Some materials can be tricky to classify. Circle what you think each one is and explain your reasoning:

Honey: Solid / Liquid / Gas

Explanation: _________________________________________________

Jelly: Solid / Liquid / Gas

Explanation: _________________________________________________

12. Reflection: Write one sentence defining matter and give an example of each state:

Matter is:

Solid example: _________________ Liquid example: _________________ Gas example: _________________
