**Lesson Plan for Primary 6 - Basic Science and Technology**
**Date:** [Insert Date]
**Title:** Frictional Force + Swimming Strokes + Scratch Project
**Duration:** 60 minutes
**Objectives:**
1. Understand the concept of frictional force.
2. Recognize and describe different swimming strokes.
3. Create a simple animation or interactive scene related to frictional force and swimming strokes using Scratch.
**Materials Needed:**
- Whiteboard and markers
- Video clips of different swimming strokes
- Small objects for friction experiments (e.g., toy cars, sandpaper, smooth surfaces)
- Computers/Tablets with Scratch software installed
- Projector and screen
- Handouts on frictional force and swimming strokes
**Lesson Structure:**
### Introduction (10 minutes)
1. **Welcome and Warm-Up:**
- Greet the students and briefly review the previous lesson.
- Introduce the topic of the day with a quick question: "What do you know about what makes things stop or go?"
### Section 1: Frictional Force (15 minutes)
1. **Explanation and Demonstration:**
- Define frictional force: "Friction is the force that resists the movement of one surface across another."
- Use small objects like toy cars on different surfaces (e.g., sandpaper vs. smooth table) to demonstrate friction.
- Discuss examples where friction is helpful (e.g., walking, car tires on the road) and where it is a problem (e.g., machine parts wearing down).
2. **Interactive Activity:**
- Divide the students into groups and give each group small objects and surfaces to experiment with.
- Have students observe and discuss which surfaces create more friction and why.
### Section 2: Swimming Strokes (15 minutes)
1. **Introduction to Swimming Strokes:**
- Show short video clips of different swimming strokes (freestyle, backstroke, breaststroke, butterfly).
- Explain each stroke with its different movements and advantages.
2. **Discussion and Q&A:**
- Engage the students by asking questions like "Which stroke looks the easiest/hardest? Why?" or "Have you ever tried swimming? What stroke did you use?"
- Hand out information sheets summarizing each stroke for further reading.
### Section 3: Scratch Project (20 minutes)
1. **Introduction to Scratch:**
- Briefly explain what Scratch is: "Scratch is a coding platform that lets you create stories, games, and animations."
- Show a simple example project related to friction and swimming strokes.
2. **Getting Started:**
- Guide the students through opening Scratch and creating a new project.
- Demonstrate basic commands to create simple animations of friction or a swimmer moving using different strokes.
3. **Hands-On Activity:**
- Allow students to work on their initiatives, creating an animation or interactive scene.
- Offer assistance and tips as they work.
### Conclusion (5 minutes)
1. **Review and Reflection:**
- Recap the key points learned about frictional force and swimming strokes.
- Invite a few students to share their Scratch projects with the class.
2. **Homework/Extension Activity:**
- Ask students to observe examples of friction at home or in their daily life and note them down.
- Encourage them to continue working on their Scratch projects at home, adding more details and interactivity.

Ensure to adapt the lesson as needed based on the students' progress and engagement. Provide additional support for students who may find coding challenging and allow advanced students to explore more complex Scratch features.
