### Lesson Plan: Life Cycles
**Grade:** Year 5
**Subject:** Science
**Duration:** 60 minutes
**Topic:** Life Cycles
---
#### Objectives:
- Understand the concept of a life cycle.
- Identify and describe the stages of a life cycle for different organisms.
- Recognize the similarities and differences in life cycles of various plants and animals.
- Develop observational and critical thinking skills.
#### Materials:
- Whiteboard and markers
- Projector and computer
- Images or models of life cycles (butterfly, frog, plant, etc.)
- Worksheets with life cycle diagrams
- Art supplies (paper, crayons, markers, scissors, glue)
- Living organisms (if possible, e.g., butterfly larvae, frog eggs) or videos showing the life cycles
#### Standards Alignment:
- NGSS 3-LS1-1: Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death.

### Lesson Outline:
**1. Introduction (10 minutes):**
- Begin with a brief discussion about what a life cycle is.
- Ask: “What do you think a life cycle is?”
- Brainstorm answers and write key terms and ideas on the whiteboard.
- Show a time-lapse video of a butterfly life cycle to engage students visually.
**2. Direct Instruction (15 minutes):**
- Explain the stages of a life cycle: birth, growth, reproduction, and death.
- Use visual aids (slides or posters) to show the life cycles of different organisms: butterflies, frogs, and plants.
- Highlight the common stages but also note the differences (e.g., metamorphosis in butterflies vs. direct growth in humans).
**3. Guided Practice (15 minutes):**
- Divide students into small groups and provide each group with a set of life cycle pictures or models.
- Have each group match the images to the correct stage of the life cycle for their assigned organism.
- Walk around and assist as needed, then review answers with the whole class.
**4. Independent Practice (10 minutes):**
- Hand out worksheets with various life cycle diagrams (e.g., frog, chicken, sunflower).
- Ask students to label the stages and describe what happens in each stage.
- Encourage them to use their textbooks or notes for reference.
**5. Creative Activity (10 minutes):**
- Provide art supplies and ask students to create their own life cycle diagram for an organism of their choice.
- They can illustrate each stage and label them.
- Optionally, they can present their diagrams to the class if time permits.
**6. Conclusion (5 minutes):**
- Recap the key points about life cycles.
- Ask some students to share interesting facts they learned.
- Provide a few questions for them to take home and think about:
- How does the life cycle of a butterfly differ from that of a frog?
- Why is it important for organisms to complete their life cycle?
---
**Assessment:**
- Observe students’ participation in group activities and discussions.
- Review the accuracy and completeness of the worksheets.
- Evaluate the creativity and correctness of the life cycle diagrams.
---
**Extensions:**
- Optional homework: Research and write a short report on an unusual life cycle (e.g., the life cycle of a jellyfish or an insect like a dragonfly).
- Organize a visit to a local botanical garden or a zoo to observe life cycles in nature.
---
**Adaptations:**
- For students with special needs, provide additional visual aids and hands-on models.
- For advanced students, encourage them to compare and contrast life cycles of different species in more detail.

By the end of this lesson, students should have a practical and comprehensive understanding of life cycles and their importance in the natural world.
