### Lesson Plan for Basic Science and Technology (Primary 2)
#### Topic: The Senses - Taste, Features of a CPU, and Athletics
---
#### Objective:
1. Understand the sense of taste and how it works.
2. Learn about the basic features of a CPU (Central Processing Unit).
3. Discuss basic athletics and the importance of exercise.
---
### 1. Introduction (5 minutes)
- **Greeting:** Welcome the students warmly.
- **Objectives Outline:** Briefly explain what they will learn about today: the sense of taste, features of a CPU in a computer, and some basic athletics activities.
---
### 2. The Senses - Taste (20 minutes)
#### Materials:
- Various food items (e.g., lemon, sugar, salt, chocolate, etc.)
- Paper and crayons
#### Activities:
1. **Discussion:**
- Ask students what they know about the five senses.
- Introduce the sense of taste. Explain that the tongue is the main organ involved in tasting.
2. **Experiment:**
- Have students close their eyes and taste different food items.
- Ask them to describe the taste (sweet, sour, salty, bitter) and guess what the food item is.
3. **Worksheet:**
- Provide a simple worksheet with pictures of the tongue and taste areas.
- Have students color the different areas where you might taste sweet, salty, sour, and bitter.
#### Wrap-up:
- Summarize by explaining how the tongue can detect different flavors and send these signals to the brain.

### 3. Features of a CPU (20 minutes)
#### Materials:
- Poster or picture of a computer (with visible CPU)
- Diagram of a CPU with labeled parts
#### Activities:
1. **Introduction:**
- Introduce the concept of a computer and what a CPU does (the brain of the computer).
2. **Explanation:**
- Use the poster/diagram to show the CPU.
- Describe the basic features of a CPU:
- **Processor:** The part that performs calculations and actions.
- **Memory:** Where data is temporarily stored.
- **Input/Output:** Interfaces to connect with other devices.
3. **Discussion:**
- Ask students if they use computers and what they use them for.
- Explain how a CPU helps them play games, learn, or watch videos.
#### Wrap-up:
- Recap the main features of a CPU and its importance in making computers work.

### 4. Athletics (20 minutes)
#### Materials:
- Open space (playground or school hall)
- Cones for marking positions
- Whistle (optional)
#### Activities:
1. **Discussion:**
- Explain what athletics is and list some activities (running, jumping, throwing, etc.)
- Discuss the importance of exercise and staying healthy.
2. **Warm-up:**
- Lead the students in a simple warm-up (stretching, light jogging).
3. **Activity:**
- Set up a simple obstacle course using cones.
- Divide students into small groups and have them complete the course (e.g., running to a cone, hopping to another, and sprinting back).
4. **Cool-down:**
- After the activity, lead students in a cool-down session (slow walking, deep breathing).
#### Wrap-up:
- Emphasize the fun and benefits of athletics, like staying healthy and working as a team.
---
### 5. Conclusion and Q&A (5 minutes)
- Recap the day’s lessons.
- Allow students to ask questions about any of the topics covered.
- Reward participation with stickers or small treats.
---
### Assessment:
- Observe student participation and understanding during activities.
- Collect and review worksheets for the taste lesson.
---
### Extension Activities:
- Create a “taste diary” for students to take home and record different tastes they experience.
- Have a drawing or coloring contest on the theme of “Computers and Their Parts.”
- Organize a small intra-class athletics competition in the future.
---
#### Additional Notes:
- Ensure that all food items used in the taste activity are checked for allergies.
- Keep the athletics activity safe and appropriate for the age group.
- Be inclusive and ensure all students are engaged and participating.
