Begin the lesson by introducing the concept that plants, like humans, need food, water, and air to survive. Highlight the unique ways plants obtain these necessities.

Explain how plants use roots to absorb water and nutrients from the soil, and how leaves take in carbon dioxide from the air.

Introduce photosynthesis as the process by which plants use sunlight, water, and carbon dioxide to make their own food, emphasizing the importance of sunlight.

Watch the video 'How Plants Grow' to understand the fundamental process of plant growth, including the development of roots, stems, and leaves.

Engage with the 'Do You Know How Plants Grow? (Quiz Edition)' video to reinforce understanding through interactive quizzes.

Conduct an experiment to observe how plants absorb water using celery stalks and colored water. This visual demonstration helps students understand the function of roots.

Have students draw and label the parts of a plant, including roots, stems, and leaves, to reinforce their understanding of plant anatomy and function.

Use the 'Do Plants Need Sunlight?' assessment to evaluate students' understanding of photosynthesis and the role of sunlight in plant growth.

Discuss with students what they learned about the needs of plants and the process of photosynthesis. Encourage them to reflect on how plants contribute to the environment.

Administer the 'Needs of Living Things' assessment to test students' comprehension of the basic needs of plants and other living organisms.

Encourage students to explore further by observing plants in their environment and noting how they meet their needs for survival.
