**Lesson Plan: Basic Science and Technology**
**Grade:** Primary 3
**Topic:** Wind
**Duration:** 1 hour
**Learning Objectives:**
1. Understand what wind is and how it is created.
2. Identify different sources of wind.
3. Discuss the uses of wind in everyday life.
4. Conduct a simple experiment to observe the effects of wind.
**Materials Needed:**
- Chart paper
- Markers
- Picture cards of various windy weather scenarios
- Pinwheels (or materials to make pinwheels)
- Paper, scissors, straws
- Small lightweight objects (e.g., feathers, paper clips)
- Fan (optional)
**Lesson Outline:**
1. **Introduction (10 minutes):**
- Begin with a quick discussion about the weather. Ask students if they've ever felt the wind. Let them share their experiences.
- Introduce the topic by explaining what wind is: "Wind is moving air. We can't see it, but we can feel it."
- Show picture cards of different scenarios where wind is apparent (e.g., leaves blowing, flags waving, kite flying).
2. **Explanation of Wind (10 minutes):**
- Explain that wind is created when the sun heats parts of the Earth unevenly, causing air to move from high-pressure areas to low-pressure areas.
- Use chart paper and markers to draw a simple diagram showing how the sun heats the Earth, leading to wind.
3. **Sources of Wind (10 minutes):**
- Discuss natural sources of wind (e.g., sea breeze, mountain breeze).
- Explain how human activities can also create wind, such as with fans or blowing air from our mouths.
- Show a fan and let children feel the "wind" to understand man-made wind.
4. **Uses of Wind (10 minutes):**
- Discuss various uses of wind in daily life:
- Flying kites
- Generating electricity with wind turbines
- Sailing boats
- Show pictures or videos of a windmill and a sailboat.
5. **Hands-On Experiment (15 minutes):**
- Distribute materials to make pinwheels. Guide students through the steps to create their own pinwheels.
- Once the pinwheels are ready, have students blow on them to see how they spin.
- If possible, use a fan to demonstrate a stronger wind and observe how the pinwheels spin faster.
**Steps to Make a Pinwheel:**
1. Cut a square piece of paper.
2. Draw diagonal lines from each corner to the center, but stop a little before reaching the center.
3. Cut along the lines you drew.
4. Fold every other corner to the center and secure with a pin through a straw.
6. **Observation and Discussion (5 minutes):**
- Ask questions to stimulate thinking: “What did you notice about the pinwheel when you blew on it? How did it change when the fan was used?”
- Discuss differences in wind strength and direction.
**Conclusion (5 minutes):**
- Recap the main points covered in the lesson:
- What wind is and how it is created.
- Different sources of wind.
- Uses of wind in daily life.
- Encourage students to observe wind in their environment and think about how it affects their daily activities.
**Assessment:**
- Observe student participation and engagement during discussions and activities.
- Review students’ pinwheels to ensure they understand how wind affects objects.
- Pose questions to individual students to check comprehension and recall of lesson content.
**Extension (Optional):**
- Assign a simple homework task where students draw a picture of a windy day and label the objects being moved by the wind.
**Tools for Inclusion:**
- Make sure all students, including those with physical or learning disabilities, are able to participate in the activities through proper adaptations where necessary (e.g., larger materials, peer assistance).
