Begin the lesson by discussing the importance of plant stems. Explain how they support the plant and transport water and nutrients.

Engage students with a question: 'Have you ever noticed different shapes of stems in plants around you?'

Explain the role of stems in supporting plants and holding them upright. Discuss how stems carry water and nutrients from the roots to the leaves.

Introduce the concept of different stem shapes and their functions in plant growth.

Watch the video 'Parts of a Plants – Roots, Stems and Leaves' to visually illustrate the functions of plant stems.

Discuss the video content and ask students to identify the different parts of a plant and their roles.

Conduct a 'Schoolyard Plant Hunt' where students observe and draw different plants, focusing on their stems.

Set up an experiment using a celery stalk and colored water to demonstrate how stems transport water.

Have students draw and label a plant, focusing on the stem and its functions.

Encourage students to observe plants at home and note the different shapes and sizes of stems.

Ask students to explain how stems support leaves, fruits, and flowers for optimal exposure and growth.

Conduct a quick quiz to assess students' understanding of the role of stems in plants.

Review the key points about stems and their functions in plant growth.

Encourage students to reflect on what they learned and how they can apply this knowledge in real life.

Use the 'Observing Roots' activity to extend learning by comparing stem functions with root functions.

Encourage students to explore how different stem shapes help plants adapt to their environment.
