Lesson Plan
Matter: It's Everywhere!
Students will be able to define matter, identify its different states (solid, liquid, gas, plasma), and distinguish between physical and chemical properties of matter.
Understanding matter is the bedrock of all chemistry. Everything around us is made of matter, and by learning its fundamental characteristics, students will gain a deeper appreciation for the world and how it works at a molecular level.

Prep
Teacher Preparation
15 minutes
- Review the Matter: It's Everywhere! Slide Deck and ensure all visuals and content are clear.
- Print copies of the Matter: What's the 'Matter'? Worksheet & Guided Notes for each student.
- Prepare and cut out the cards for the Matter: Property Hunt Activity Cards. Ensure you have enough sets for small groups.
- Gather any additional materials needed for demonstrations if desired (e.g., ice, water, steam to show states of matter).
Step 1
Warm-Up: What Do You Think?
5 minutes
- Begin by asking students: 'When you hear the word 'matter', what comes to mind?'
- Facilitate a brief class discussion, writing down key terms on the board.
- Introduce the lesson title: 'Matter: It's Everywhere!' (Refer to Matter: It's Everywhere! Slide Deck - Slide 1).
Step 2
Introduction to Matter
10 minutes
- Present the definition of matter: anything that has mass and takes up space (volume). (Refer to Matter: It's Everywhere! Slide Deck - Slides 2-3).
- Discuss examples and non-examples of matter.
- Introduce the concept of states of matter: solid, liquid, gas, and plasma. (Refer to Matter: It's Everywhere! Slide Deck - Slides 4-7).
- Explain the characteristics of each state, focusing on particle arrangement and energy.
- Students should fill in the guided notes section of their Matter: What's the 'Matter'? Worksheet & Guided Notes during this time.
Step 3
Properties of Matter
15 minutes
- Define physical properties (can be observed or measured without changing the substance's identity) and chemical properties (describe how a substance reacts to form new substances). (Refer to Matter: It's Everywhere! Slide Deck - Slides 8-9).
- Provide clear examples for each, such as color, density, melting point (physical), and flammability, reactivity (chemical).
- Students continue filling in their guided notes on the Matter: What's the 'Matter'? Worksheet & Guided Notes.
Step 4
Matter Property Hunt Activity
15 minutes
- Divide students into small groups (3-4 students).
- Distribute the Matter: Property Hunt Activity Cards to each group.
- Instructions: Each card describes a property. Groups must identify if it's a physical or chemical property and provide a brief explanation.
- Circulate and assist groups, fostering discussion and clarifying misconceptions.
Step 5
Class Discussion and Review
8 minutes
- Bring the class back together.
- Review answers from the Matter: Property Hunt Activity Cards, addressing any common challenges.

- Address any remaining student questions.
Step 6
Cool-Down: One Question
5 minutes
- Ask students to answer the following question on their Matter: What's the 'Matter'? Worksheet & Guided Notes as an exit ticket: 'Explain in your own words the difference between a physical property and a chemical property, providing one example for each.'
- Collect worksheets.

Slide Deck
Matter: It's Everywhere!
What comes to mind when you hear the word 'matter'?
Welcome students and ask them what comes to mind when they hear the word 'matter'. Encourage a quick brainstorm before revealing the lesson title.
What is Matter?
Matter is anything that has mass and takes up space (volume).
- Mass: A measure of the amount of 'stuff' in an object.
- Volume: The amount of space an object occupies.
Introduce the formal definition of matter. Emphasize the two key components: mass and volume.
Matter: Examples & Non-Examples
Examples of Matter:
- A rock
- Water
- Air
- You!
Non-Examples of Matter:
- Light
- Heat
- Sound
- Ideas
Why are these non-examples? Discuss how they don't have mass or take up space.
Provide examples and non-examples to solidify understanding. Ask students for more examples.
States of Matter: Solids
Solids:
- Have a definite shape and a definite volume.
- Particles are tightly packed and vibrate in fixed positions.
- Strong attractive forces between particles.
Introduce the concept of states of matter. Start with solids.
States of Matter: Liquids
Liquids:
- Have an indefinite shape (takes the shape of its container) but a definite volume.
- Particles are close together but can slide past one another.
- Moderate attractive forces between particles.
Move to liquids. Highlight the difference in particle movement.
States of Matter: Gases
Gases:
- Have an indefinite shape and an indefinite volume (fills its container).
- Particles are far apart and move randomly and rapidly.
- Very weak attractive forces between particles.
Discuss gases. Emphasize the lack of definite shape or volume.
States of Matter: Plasma
Plasma:
- An ionized gas (atoms have lost or gained electrons).
- Extremely high energy.
- Found in stars, lightning, and fluorescent lights.
Briefly introduce plasma as the fourth state, often found in stars and lightning.
Properties of Matter: Physical
Physical Properties:
- Can be observed or measured without changing the substance's identity.
- Examples:
- Color
- Density
- Melting point
- Boiling point
- Hardness
- Conductivity
Define physical properties. Ask students to think of examples.
Properties of Matter: Chemical
Chemical Properties:
- Describe how a substance reacts to form new substances.
- Observed during a chemical change (a chemical reaction).
- Examples:
- Flammability (ability to burn)
- Reactivity with acids
- Oxidation (rusting)
- Toxicity
Define chemical properties. Stress that these describe how a substance reacts.
Recap: What is Matter?
We've learned:
- Matter has mass and volume.
- The four states of matter are solid, liquid, gas, and plasma.
- Physical properties can be observed without changing identity.
- Chemical properties describe how a substance reacts.
Summarize the key takeaways and open for any final questions.

A physical property is something you can observe about an object without changing what it is. For example, its color, like a blue car. A chemical property describes how a substance changes into a new substance. For example, wood burning and turning into ash and smoke.


Answer Key

Instructions: For each card, determine if the description refers to a Physical Property or a Chemical Property. Write your answer and a brief explanation in the space provided.
Card 1
Description: A piece of wood can be cut into smaller pieces.
Property Type: Physical Property
Explanation: Cutting the wood changes its size and shape, but it is still wood. Its chemical identity remains the same.
Card 2
Description: Iron will rust when exposed to oxygen and moisture.

Explanation: When sugar dissolves, it disperses in the water, but it doesn't change into a new substance. You can still evaporate the water and get the sugar back.
Card 7
Description: A newspaper left in the sun turns yellow over time.
Property Type: Chemical Property
Explanation: The change in color indicates a chemical reaction, usually oxidation, where the paper's chemical composition is altered.
Card 8
Description: The density of aluminum is 2.7 g/cm³.
Property Type: Physical Property
Explanation: Density is a measure of how much mass is in a given volume; it can be determined without changing the aluminum into a new substance.
