Start the lesson by introducing the concept of matter. Explain that everything around us, including the air we breathe, the water we drink, and the toys we play with, is made up of matter.

Engage students with a question: 'What are some examples of matter in our classroom?' This will help them start thinking about the presence of matter in their everyday environment.

Introduce the video 'What is Matter?' to explain the concept of matter, its characteristics, and the three states of matter—solids, liquids, and gases.

Discuss how we can describe matter by its size, color, and shape. Use examples from the classroom to illustrate these characteristics.

Watch the video 'Describing Matter' to explore how to identify properties such as shape, size, color, and texture using our senses.

Encourage students to describe the matter in their bedroom by discussing the size, color, and shape of objects they can see.

Engage students in a tactile exploration activity using the 'What's the Secret Object?' assessment. Have them use their sense of touch to identify hidden objects and describe their texture and shape.

Have students complete the 'Describing Objects' assessment where they describe objects by checking boxes labeled hard, soft, rough, or smooth.

Conduct a class discussion to review what students have learned about matter. Ask them to share examples of matter and describe their properties.

Use the 'Review – Matter' assessment to reinforce students' understanding of matter, its states, and properties through activities such as true or false questions and descriptive writing.

Encourage students to try the quiz to test their comprehension of the topic.

For further exploration, students can engage in the 'Sorting and Grouping Objects' assessment to deepen their understanding of classification based on observable characteristics.
