**Topic:** The Senses - Touch + Features of CPU + Athletics
---
### **Lesson Objectives:**
By the end of the lesson, students should be able to:
1. Understand and identify the sense of touch and its importance.
2. Describe the basic features and function of the CPU in a computer.
3. Understand the basic concepts of athletics and participate in simple athletic activities.
### **Materials Needed:**
- Various textured objects (e.g., cotton balls, sandpaper, fabric)
- Pictures or a simple model of a computer showing the CPU
- Visual aids or posters on athletic activities
- Cones, stopwatch, and a whistle for athletic activities
- Chalkboard/Dry-erase board and markers

### **Lesson Breakdown:**
**Part 1: The Sense of Touch (20 minutes)**
1. **Introduction (5 minutes):**
- Start by asking students to name the five senses.
- Focus on the sense of touch. Ask students to explain how they know something is rough, smooth, hot, or cold.
2. **Activity 1: Touch and Tell (10 minutes):**
- Provide each student with different textured objects.
- Let them describe how each object feels.
- Write their descriptions on the board under categories like “rough,” “smooth,” “soft,” etc.
3. **Discussion and Conclusion (5 minutes):**
- Explain that our skin, especially on our fingers, has thousands of nerve endings that help us sense things.
- Highlight the importance of the sense of touch in daily life.
**Part 2: Features of CPU (20 minutes)**
1. **Introduction (5 minutes):**
- Show a picture or model of a computer.
- Ask students if they know what a CPU is and what it does.
2. **Explanation (10 minutes):**
- Explain that the CPU (Central Processing Unit) is like the brain of the computer.
- Describe basic features such as processing speed and memory.
- Use simple terms to explain how the CPU helps the computer run different programs.
3. **Activity 2: Label the Parts (5 minutes):**
- Hand out worksheets with a picture of a computer.
- Let students label the CPU and other basic parts like the monitor, keyboard, and mouse.
**Part 3: Athletics (20 minutes)**
1. **Warm-Up and Introduction (5 minutes):**
- Explain that athletics includes running, jumping, and throwing.
- Do a quick warm-up session with simple stretches.
2. **Activity 3: Relay Races (10 minutes):**
- Set up a simple relay race using cones.
- Divide the students into teams and have them participate in the relay race.
3. **Cool Down and Review (5 minutes):**
- Conduct a cool-down session with light stretching.
- Ask students to share which part of athletics they enjoyed the most and why it’s important to stay active.
### **Assessment:**
- Observe students during activities to ensure participation and understanding.
- Quick oral questions at the end of each part to assess comprehension.
- Review worksheet answers for accuracy.
### **Conclusion:**
- Recap the key points of each topic.
- Encourage students to think about how they use their sense of touch every day, the importance of the CPU in technology, and why physical activity through athletics is beneficial.
### **Homework:**
- Draw and label five objects you can identify by touch.
- Write two sentences about what you learned about the CPU.
- Draw a picture of you doing your favorite athletic activity.
