**Lesson Plan: Classification of Plants According to Lifespan**
**Grade: Primary 5**
**Subject: Agricultural Science**
**Duration: 60 minutes**
**Topic: Classification of Plants According to Lifespan**
---
**Objectives:**
1. Students will understand the concept of plant lifespan.
2. Students will be able to classify plants based on their lifespan: annuals, biennials, and perennials.
3. Students will learn the characteristics and examples of each type of plant.
4. Students will engage in a hands-on activity to reinforce their understanding of plant classification.

**Materials Needed:**
- Whiteboard and markers
- Chart paper and markers
- Sample plants or pictures of plants (examples of annuals, biennials, and perennials)
- Worksheet/activity sheet
- Scissors, glue, crayons, and colored pencils
- Sample seeds (optional)

**Lesson Outline:**
**Introduction (10 minutes)**
1. **Greeting and Attendance:**
- Warmly greet the students and take attendance.
2. **Introduction to Topic:**
- Write the topic on the whiteboard: "Classification of Plants According to Lifespan."
- Explain that today they will learn how different plants grow and live for different periods.
**Instructional Input (20 minutes)**
1. **Define Lifespan:**
- Ask students if they know what 'lifespan' means. Explain that it is the length of time a plant lives.
2. **Classification According to Lifespan:**
- **Annuals:**
- Explain that annual plants complete their lifecycle in one growing season.
- Examples: corn, beans, marigolds.
- Show pictures or samples.
- **Biennials:**
- Explain that biennial plants take two years to complete their lifecycle.
- Examples: carrots, onions, foxgloves.
- Show pictures or samples.
- **Perennials:**
- Explain that perennial plants live for more than two years.
- Examples: roses, apple trees, lavender.
- Show pictures or samples.
3. **Characteristics of Each Type:**
- Discuss the general characteristics of annuals, biennials, and perennials (e.g., planting season, flowering, and harvesting).
**Activity (20 minutes)**
1. **Group Activity:**
- Divide the class into small groups.
- Provide each group with chart paper, markers, and pictures or samples of plants.
- Ask each group to create a poster with the three classifications (annuals, biennials, perennials) and place the pictures in the correct category.
- Allow students to use scissors, glue, crayons, and colored pencils to decorate their posters.
2. **Class Discussion:**
- Have each group present their poster to the class.
- Encourage other students to ask questions and provide feedback.
**Assessment (10 minutes)**
1. **Worksheet:**
- Hand out a worksheet with a mix of plant names and pictures.
- Ask students to classify each plant as an annual, biennial, or perennial.
2. **Review Answers:**
- Go over the answers as a class and provide feedback.
**Conclusion (5 minutes)**
1. **Summary:**
- Recap the key points about plant classification according to lifespan.
- Ask a few students to share something new they learned today.
2. **Announcement:**
- Inform the students about the next lesson topic and any homework or materials they need to bring.
3. **Closing:**
- Thank the students for their participation and hard work.
---
**Homework:**
- Ask students to draw and color one example of an annual, biennial, and perennial plant on a sheet of paper and write a sentence about each.
**Extension Activity (Optional):**
- Grow some seeds in the classroom and observe their growth over time, noting which are annuals, biennials, or perennials.
