### Lesson Plan: Dry the Objects Moulded
#### Subject: Basic Science and Technology
#### Grade Level: Primary 2
#### Duration: 60 minutes
#### Topic: Dry the Objects Moulded
#### Learning Objectives:
By the end of the lesson, students should be able to:
1. Understand the process of drying objects made from wet substances (e.g., clay).
2. Describe why drying is important for objects that are moulded.
3. Identify different methods for drying moulded objects.
4. Practically dry an object they have moulded.
#### Materials Needed:
- Clay or Playdough
- Water
- Trays for drying
- Small fans (optional)
- Towels
- Pictures illustrating the drying process
- Chart paper and markers
#### Introduction (10 minutes):
1. **Greeting and Settling Down**:
- Greet the students and ask them about their previous lesson.
- Briefly review what they learned about moulding objects.
2. **Introduction to Drying**:
- Ask the students if they have ever left something out to dry, like clothes, and what happens when they do.
- Explain that after we mould objects, we need to dry them so they can get hard and keep their shape.
- Show a picture of a wet clay object and a totally dried one, and discuss the differences.
#### Development (30 minutes):
1. **Explanation and Discussion (10 minutes)**:
- Talk about the importance of drying moulded objects: It makes them hard and durable.
- Discuss different methods to dry objects: natural air drying, using fans, and drying with towels.
- Show pictures of the drying methods and ask students to describe what they see.
2. **Demonstration (10 minutes)**:
- Demonstrate how to dry a wet moulded object.
- Mould a small object with clay in front of the class.
- Use a towel to blot excess water, place it on a tray, and then set it near a fan (if available) or leave it out in the air.
3. **Activity (10 minutes)**:
- Give each student a small piece of clay to mould into their chosen shape.
- After moulding, instruct them to follow one of the drying methods discussed (like air drying).
- Walk around the classroom and assist where necessary.
#### Conclusion (10 minutes):
1. **Review and Recap**:
- Briefly recap the key points from the lesson: why we dry moulded objects and different methods to do so.
- Ask a few students to explain in their own words why drying is important.
2. **Q&A and Feedback**:
- Encourage students to ask questions about the drying process.
- Provide positive feedback and correct any misconceptions.
#### Assessment:
- Observe students during the activity to ensure they are following the drying methods properly.
- Ask oral questions throughout the lesson to measure understanding.
- Review each student’s dried object in the next class and discuss the results.
#### Homework:
- Ask students to draw a picture of an object that can be dried and write one sentence about why drying is important.
#### Extension Activities (Optional):
- Experiment with drying times by placing identical objects in different environments (sunlight, shade, fan) and comparing the results.
- Create a simple chart or timeline that records how long it takes for objects to dry using different methods.
