Begin the lesson by introducing the concept of plant stems as the 'bridge' of the plant, connecting roots to leaves. Highlight their roles in support, transport, and storage.

Discuss the differences between herbaceous and woody stems, using examples like tomato plants and trees to illustrate their characteristics.

Explain the role of vascular tissues in stems, focusing on xylem and phloem, and their importance in transporting water, minerals, and food.

Watch the video 'Parts of a Plants – Roots, Stems and Leaves' to visually explore the functions of plant stems and their importance in plant biology.

Conduct an investigation to observe vascular tissue in stems by using colored water and flowers. This activity helps students see how water is transported through xylem vessels.

Have students complete the 'Stems – Comprehension' worksheet to reinforce their understanding of stem structure and function.

Engage students in a discussion about the importance of stems in photosynthesis, especially in herbaceous plants, and their role in supporting plant life.

Review the key functions of plant stems and their importance in the plant's overall structure and survival. Encourage students to reflect on what they have learned.

Test students' comprehension with the 'Classifying Plants in the Schoolyard' assessment, which encourages observation and classification skills.

Encourage further exploration by trying the quiz to assess understanding of plant structures and functions.
