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.
Go to the LessonLearning Objectives
- Understand that plants need food, water, and air to survive.
- Identify how plants use roots to absorb water and nutrients from the soil.
- Explain how plants use leaves to take in carbon dioxide from the air.
- Describe the process of photosynthesis and its importance to plant survival.
- Recognize the importance of sunlight in the process of photosynthesis.
Introduction and Hook
Direct Instruction
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.
Guided Exploration
Watch the video 'How Plants Grow' to understand the fundamental process of plant growth, including the development of roots, stems, and leaves.
Hands-On Activity
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.
Independent Practice
Have students draw and label the parts of a plant, including roots, stems, and leaves, to reinforce their understanding of plant anatomy and function.
Check for Understanding
Review and Reflection
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.
Assessment and Extension
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.
