Begin the lesson with an engaging question: 'What happens inside a seed when it starts to grow?' This question will spark curiosity and set the stage for learning about seed germination.
Go to the LessonLearning Objectives
- Understand the basic structure of a seed, including the seed coat, embryo, and cotyledons.
- Explain the process of seed germination and the conditions required for it to occur.
- Describe the role of the root and shoot during the early stages of plant growth.
- Identify the transition from a seed to a seedling and the beginning of photosynthesis.
Introduction and Hook
Direct Instruction
Explain the basic structure of a seed, including the seed coat, embryo, and cotyledons, using diagrams and models to illustrate these components.
Discuss the conditions necessary for seed germination: air, water, and warmth, and how each contributes to the process.
Guided Exploration
Watch the video 'Seed Dispersal' to understand how seeds travel and find suitable places to grow, enhancing comprehension of the natural processes that aid plant propagation.
Facilitate a discussion on the role of the root and shoot during early plant growth, emphasizing their functions and importance.
Hands-On Activity
Conduct an experiment using bean seeds to observe seed germination. Plant seeds in clear plastic cups and monitor their growth over two weeks.
Independent Practice
Assign students to draw and label the parts of a seed and a seedling, reinforcing their understanding of seed anatomy and early plant development.
Check for Understanding
Review and Reflection
Facilitate a class discussion to reflect on the process of seed germination and the transition from seed to seedling, encouraging students to share observations from their experiments.
Assessment and Extension
Administer the 'What Do Plants Need to Survive?' assessment to test students' understanding of the essential conditions for plant growth.
