Begin the lesson by discussing the basic needs of plants, such as sunlight, air, water, nutrients, and a place to grow. Engage students with questions about how plants differ from animals in obtaining food.

The Needs of Plants
Learning Objectives
- Understand that plants need sunlight, air, water, nutrients, and a place to grow.
- Explain how plants use sunlight, air, and water to make food through photosynthesis.
- Identify the differences between how plants and animals obtain food.
Introduction and Hook
Introduce the concept of photosynthesis and its importance in plant life. Use a simple analogy to explain how plants 'make' their own food.
Direct Instruction
Use the video 'What is Photosynthesis?' to explain how plants use sunlight, carbon dioxide, and water to produce glucose and oxygen. This video provides a clear demonstration of the photosynthesis process.
Discuss the role of plant parts in growth and survival using the video 'Parts of a Plants – Roots, Stems and Leaves'. This video helps students understand the functions of different plant parts.
Guided Exploration
Facilitate a discussion on how plants meet their needs in different environments. Encourage students to think about how plant structures support their survival.
Watch 'What Do Plants Needs to Live and Grow' to explore the essential needs of plants for survival. This video highlights the roles of sunlight, water, and carbon dioxide.
Hands-On Activity
Conduct an experiment where students observe plant growth under different conditions. Have them predict, observe, and record how sunlight and water affect plant growth.
Use the 'Observing Plant Parts' assessment to have students explore plant parts by observing a small potted plant. This activity assesses understanding of plant structure and function.
Independent Practice
Assign students to draw and label the parts of a plant, explaining how each part contributes to the plant's survival and growth.
Have students complete the 'What Do Plants Need to Live and Grow?' assessment to reinforce their understanding of plant needs.
Check for Understanding
Conduct a class discussion to review the key concepts of the lesson. Ask students questions to assess their understanding of photosynthesis and plant needs.
Use the 'Review – Plants and Animals' assessment to evaluate students' comprehension of the lesson material.
Review and Reflection
Have students reflect on what they learned about plant needs and photosynthesis. Encourage them to share their thoughts and any questions they still have.
Watch 'How Plants Grow' to reinforce the concepts learned and provide a visual summary of plant growth and photosynthesis.
Assessment and Extension
Assign the 'Do You Know How Plants Grow? (Quiz Edition)' video quiz to test students' understanding of the plant life cycle and reinforce key concepts.
Try the Quiz
Encourage students to explore further by researching different plant adaptations and how they help plants meet their needs in various environments.
