### Lesson Plan for Basic Science and Technology
**Topic**: Weather + Tennis + Launching of Paint
**Grade**: Primary 4
**Duration**: 1 hour
---
**Objectives**:
1. Understand the basic concepts of weather and its elements.
2. Introduce the fundamentals of tennis.
3. Conduct a simple science experiment involving the launching of paint.
**Materials**:
- Whiteboard and markers
- Pictures or charts depicting different weather conditions
- Tennis rackets and balls
- Protective clothing (old shirts, aprons)
- Paints (various colors)
- Balloons
- Large sheets of paper or old fabric
- Empty plastic bottles (to serve as launchers)
**Essential Questions**:
1. What are the different types of weather?
2. How is tennis played?
3. How can we use science to launch paint creatively?

### Introduction (10 minutes):
1. **Greeting and Warm-Up**: Welcome the students and briefly introduce the lesson plan.
2. **Weather Discussion**:
- Ask the students: "What is weather and why is it important?"
- Discuss different types of weather (sunny, rainy, snowy, windy, cloudy).
- Use pictures or charts to visualize these weather conditions.
### Main Activities (40 minutes):
#### Activity 1: Exploring Weather (10 minutes)
- **Discussion**: Talk about how weather affects daily activities, including sports.
- **Interactive Prompt**: "Imagine playing tennis on a windy day—how do you think the weather would affect the game?"
#### Activity 2: Introduction to Tennis (15 minutes)
- **Basic Rules and Techniques**:
- Show basic tennis strokes (forehand, backhand, serve).
- Demonstrate using tennis rackets and balls.
- **Mini Drills**:
- Students pair up and practice simple rallies.
- Encourage them to think about how weather (wind, sun) might affect their play.
#### Activity 3: Launching of Paint (15 minutes)
- **Safety Precautions**:
- Ensure students wear protective clothing.
- **Experiment**:
- Fill balloons with paint.
- Use plastic bottles to create simple launchers.
- Students work in groups to launch paint onto large sheets of paper or fabric.
- **Creative Observation**:
- Discuss how different forces (angle, pressure) affected the paint's trajectory.
- Connect the experiment with real-life applications, such as weather influencing tennis.
### Conclusion (10 minutes):
1. **Recap**:
- Reiterate the key points about weather, the basics of tennis, and the science experiment.
- Ask questions and encourage students to share their observations and thoughts.
2. **Q&A**:
- Address any remaining questions.
3. **Reflection**:
- Ask students to reflect on what they learned and how different subjects (weather, sports, and science) can creatively intersect.
### Assessment:
- **Participation**: Observe students' involvement in discussions and activities.
- **Q&A Responses**: Evaluate understanding through their responses.
- **Experiment Observation**: Assess their ability to make connections between the experiment and real-life weather conditions affecting tennis.
### Extension Activities:
- **Weather Journal**: Have students keep a daily journal where they note the weather conditions and how it might affect outdoor activities.
- **Creative Art**: Allow students to use the launched paint sheets to create an art project related to weather or sports.
