π What is the Plant Life Cycle?
The plant life cycle describes how a plant grows, reproduces, and eventually dies. It's a repeating cycle, meaning new plants will grow from the seeds of older plants. Think of it like a circle of life, but for plants!
π± Objectives
- π― Students will be able to identify the four main stages of the plant life cycle.
- π§ Students will be able to describe what happens at each stage.
- βοΈ Students will be able to draw and label a diagram of the plant life cycle.
π Materials
- βοΈ Paper and pencils
- ποΈ Crayons or colored pencils
- π» Seeds (bean or sunflower seeds work well!)
- π± Small pots and soil
- π§ Water
βοΈ Warm-up (5 mins)
Ask students what they already know about plants. Where do they come from? What do they need to grow? Write their ideas on the board.
πΏ Main Instruction
Explain the four stages of the plant life cycle, using simple language and visuals.
1. π§ Seed
- π What it is: The very beginning! A seed contains everything a new plant needs to start growing.
- π± What happens: When a seed has the right conditions (water, warmth, and sometimes light), it starts to germinate.
- βοΈ Activity: Show different kinds of seeds and have students draw what they think the plant inside looks like.
2. πͺ΄ Germination
- π What it is: This is when the seed starts to sprout.
- π± What happens: The seed coat cracks open, and a tiny root emerges, followed by a small shoot.
- π§ͺ Experiment: Plant seeds in a clear cup so students can watch the roots grow over a few days. Make sure to water it!
3. π Growth
- π What it is: The plant gets bigger and stronger.
- π± What happens: The plant develops leaves, stems, and roots. It uses sunlight, water, and nutrients from the soil to grow.
- π‘ Tip: Discuss how plants make their own food through photosynthesis!
4. πΈ Reproduction
- π What it is: The plant makes new seeds to start the cycle again.
- π± What happens: Many plants grow flowers, which are pollinated to produce fruits containing seeds.
- π Activity: Discuss how bees help with pollination.

Assessment
Have students draw and label the four stages of the plant life cycle. Ask them to write a short sentence describing what happens at each stage.
π Example Assessment Questions:
- β What is the first stage of the plant life cycle?
- β What does a seed need to germinate?
- β What part of the plant helps it make its own food?
- β How do flowers help the plant reproduce?
π± Further Exploration
- π Research different types of plants and their unique life cycles.
- π Read books about plants and gardening.
- π» Start a classroom garden!
