**Grade:** Primary 5
**Subject:** Basic Science and Technology
---
**Lesson Duration:** 90 minutes
**Objectives:**
1. Understand the concept of changes in the environment and classify them as reversible or irreversible changes.
2. Explore creativity through rhythmic patterns in music.
3. Introduce and practice basic keyboard shortcuts to enhance computer skills.

**Materials:**
- Whiteboard and markers
- Projector and computer
- Internet access
- Sets of different objects for demonstration (ice cubes, paper, clay, candles, etc.)
- Musical instruments (percussion instruments, drums, etc.)
- Sheet music or rhythm patterns
- Computers or laptops for each student or group

### Part One: Changes Around Us (30 minutes)
**Introduction (5 minutes):**
- Begin with a brief discussion about the term "change.” Ask students for examples of changes they notice in their everyday environment (e.g., melting ice, ripening fruit, rusting iron).
**Activity 1: Demonstration and Classification (15 minutes):**
1. **Demonstration:**
- Use the set of objects to demonstrate changes: melting ice cubes, tearing paper, kneading clay, and lighting a candle.
2. **Discussion:**
- Discuss the nature of each change and classify them:
- **Reversible Changes:** Changes that can be reversed (e.g., melting ice – can refreeze).
- **Irreversible Changes:** Changes that cannot be reversed (e.g., burning paper – cannot turn back into paper).
**Activity 2: Group Activity (10 minutes):**
- Divide the students into small groups and give each group a set of objects.
- Ask each group to discuss and classify each change as reversible or irreversible.
- Have each group present their findings to the class.

### Part Two: Creativity in Rhythm (30 minutes)
**Introduction (5 minutes):**
- Briefly talk about rhythm in music and how it is an important element in creating different types of music.
**Activity 1: Rhythm Patterns (10 minutes):**
1. **Demonstration:**
- Show basic rhythmic patterns using clapping or percussion instruments.
- Use the sheet music or rhythmic patterns to display visual cues.
2. **Practice:**
- Ask students to replicate the rhythmic patterns using claps or available percussion instruments.
**Activity 2: Creative Rhythm Session (15 minutes):**
- Divide students into small groups.
- Provide each group with percussion instruments.
- Instruct each group to create a unique rhythmic pattern and practice it.
- Allow each group to present their rhythmic pattern to the class.

### Part Three: Keyboard Shortcuts (30 minutes)
**Introduction (5 minutes):**
- Discuss the importance of keyboard shortcuts in improving efficiency while using computers.
**Activity 1: Introduction to Basic Shortcuts (10 minutes):**
1. **Demonstration:**
- Using a projector, demonstrate common keyboard shortcuts:
- **Copy (Ctrl+C)**
- **Paste (Ctrl+V)**
- **Cut (Ctrl+X)**
- **Undo (Ctrl+Z)**
- **Save (Ctrl+S)**
- **Print (Ctrl+P)**
2. **Practice:**
- Provide each student with a list of shortcuts and a practice document.
- Ask them to perform each shortcut on the document.
**Activity 2: Keyboard Shortcut Challenge (15 minutes):**
- Organize a fun challenge where students have to complete a task or a series of tasks (e.g., copy and paste sentences, undo actions, save files) using only keyboard shortcuts.
- Monitor their progress and provide assistance as needed.
---
**Closure and Assessment:**
1. **Recap of the Lesson (5 minutes):**
- Recap key points from each part of the lesson.
- Ask a few questions to ensure understanding.
2. **Assessment:**
- Check students’ understanding through their participation in the group activities and the keyboard shortcut challenge.
- Provide feedback and additional help if necessary.
---
**Homework:**
1. **Changes Around Us:**
- Ask students to observe and list at least five changes they see at home, classify them as reversible or irreversible, and explain why.
2. **Rhythm Practice:**
- Encourage students to practice creating new rhythms using household items as instruments.
3. **Keyboard Shortcuts:**
- Give a short worksheet with actions that need keyboard shortcuts and ask students to fill in the correct shortcuts.
