### Lesson Plan: Basic Science and Technology for Primary 4
**Topic: Forms of Energy + Swimming + Sources of Information**
---
#### **Lesson Objectives**
By the end of this lesson, students should be able to:
1. Identify and describe different forms of energy (e.g., light, heat, sound, electrical).
2. Understand the basic principles of swimming and its benefits.
3. Recognize various sources of information and their relevance.
#### **Materials Needed**
- Flashcards with different forms of energy illustrated
- Swimming safety posters
- Access to a computer or projector for showing informational videos
- Book samples, pictures of computers, and newspapers for sources of information
#### **Lesson Structure**
1. **Introduction (5 minutes)**
- Engage students with a quick warm-up activity: Ask students to think about and list different ways they use energy in their daily lives.
2. **Forms of Energy (15 minutes)**
- **Discussion**: Briefly introduce what energy is and why it is important.
- **Activity**: Show flashcards with different forms of energy (light, heat, sound, electrical). Ask students to identify and describe each form.
- **Hands-on Demonstration**: Set up a simple experiment to show how energy can change forms (e.g., using a flashlight to demonstrate electrical energy converting to light energy).
- **Interactive Questions**: Ask students how they think each type of energy is used in daily life.
3. **Swimming Basics (15 minutes)**
- **Introduction**: Discuss why swimming is an important skill and a good form of exercise.
- **Safety Rules**: Display swimming safety posters and talk about key safety rules (e.g., never swim alone, do not run near the pool).
- **Basic Techniques**: Explain basic swimming techniques and demonstrate basic arm and leg movements (this can be done through a video or a simple demonstration in class).
- **Interactive Questions**: Share benefits of swimming, ask students if they swim, and what they enjoy about it.
4. **Sources of Information (15 minutes)**
- **Discussion**: Explain what sources of information are and why it's important to know about them.
- **Activity**: Show students a variety of sources of information (books, computers, newspapers, and images of digital sources).
- **Role-Play**: Divide students into small groups and assign each group a source of information. Have them role-play how they would use that source to find information on a specific topic (e.g., finding information about animals).
- **Interactive Questions**: Ask students how they usually find information for their homework or projects.
5. **Review and Conclusion (5 minutes)**
- Recap the main points of the lesson by asking students questions about each section.
- Give students a quick quiz or game to reinforce the day's learning.
- Assign a homework task: Find an example of a form of energy used at home, learn a new fact about swimming, and look up something interesting using a different source of information.

#### **Assessment**
- Observe students' participation during the discussion and activities.
- Evaluate students' understanding through their responses during the interactive questions and the role-play activity.
- Assess the homework for comprehension and ability to apply the day’s learning.
#### **Homework**
1. Find and describe one example of a form of energy used at home.
2. Learn and write down one new fact about swimming.
3. Use a different source of information (like a book, internet, or newspaper) to look up something interesting and come ready to share it in the next class.

**Note**: Adjust time allocation as needed based on class size and student engagement. Ensure to incorporate interactive and hands-on activities to maintain student interest and understanding.
