Learning Objectives

• Identify solids, liquids, and gases.
• Describe matter using observable properties such as color, shape, size, texture, and state.
• Sort and classify objects based on their properties.
• Explain simple changes in matter, such as heating and cooling, in age-appropriate terms.
• Demonstrate understanding through review tasks and an independent assessment.

Materials Needed

• Pictures or samples of common objects (rock, water, balloon, pencil, ice cube, sponge, paper, air in a balloon)
• State of matter sorting cards
• Property word cards
• Chart paper or whiteboard
• Markers
• Student review sheet or assessment
• Pencils
• Optional: small cups, ice, water, zip-top bags, thermometers

Support

• Provide word banks with pictures for key vocabulary.
• Use sentence stems such as 'I know this is a ___ because ___.'.
• Pair students strategically for partner sorting.
• Allow students to point, match, or verbally explain instead of writing full sentences when needed.
• Chunk directions and model one example before independent work.

Challenge

• Ask students to compare two objects and explain more than one property.
• Have students describe how heating or cooling can change matter.
• Encourage students to justify why some objects may be difficult to classify.
• Invite fast finishers to create their own matter example and write a clue for classmates to solve.

Checks for Understanding

• Cold-call or volunteer quick oral responses during warm-up.
• Listen for correct use of vocabulary during partner sorting.
• Review student explanations during station work.
• Use thumbs up/down to check understanding of solids, liquids, and gases.
• Collect the independent assessment to measure mastery.

Closure

End with a brief class recap: matter has mass and takes up space, and it can be described by its properties and state. Ask students to name one solid, one liquid, and one gas before dismissing.
