Identify the three common states of matter: solid, liquid, and gas.
Explain that matter has mass and takes up space.
Classify everyday objects as matter or not matter.

Materials Needed

Whiteboard and markers
Pictures or real examples of everyday objects
Small items such as a book, pencil, cup of water, and balloon
Student notebook or paper
Exit ticket slips

Lesson Sequence

Warm-Up5 minutes

Teacher Actions

Show several familiar objects and ask, 'What do these have in common?' Introduce the word matter.

Student Actions

Observe the objects and share ideas with a partner and then the class.

Direct Instruction10 minutes

Teacher Actions

Define matter as anything that has mass and takes up space. Explain solids, liquids, and gases with simple examples.

Student Actions

Listen, take brief notes, and repeat key vocabulary when prompted.

Guided Practice10 minutes

Teacher Actions

Hold up or show pictures of items and ask students to identify each as a solid, liquid, or gas, and explain why.

Student Actions

Respond orally or by raising hands, using the vocabulary words.

Activity10 minutes

Teacher Actions

Have students complete a quick sorting task in pairs: sort example items into matter categories or 'not matter' if applicable.

Student Actions

Work with a partner to sort items and explain choices.

Independent Practice5 minutes

Teacher Actions

Ask students to write two examples of matter and one sentence explaining why they are matter.

Student Actions

Independently write responses in notebooks.

Review and Exit Ticket5 minutes

Teacher Actions

Review the definition of matter and collect a short exit ticket with one question about matter.

Student Actions

Complete the exit ticket before leaving.

Support

Provide sentence starters such as 'Matter is...' and 'This is matter because...'
Use pictures and real objects for visual support.
Pair students strategically for peer support.
Allow oral responses instead of written responses when needed.

Challenge

Ask advanced students to explain the difference between mass and volume.
Have students give an example of matter in each state and describe its properties.
Challenge students to identify examples of matter in the classroom and justify their choices.

Checks for Understanding

Ask: 'Does it have mass and take up space?'
Thumbs up/down for solid, liquid, or gas examples.
Listen for correct use of vocabulary during partner talk.
Use the exit ticket to check understanding.

Closure

End by restating the big idea: matter is anything that has mass and takes up space. Ask students to name one thing they learned and one example of matter from the classroom.

Assessment

Formative assessment will include teacher observation during discussion and sorting, plus the exit ticket to check whether students can define matter and identify its states.

Homework

Find three examples of matter at home and write one sentence for each explaining why it is matter.
