Hi, young learners! Welcome back to Primary 2 Basic Science And Technology. In our previous lesson, we learned about Drying Moulded Objects – Drying With Fire. Today, we’re going to learn about Exhibiting Moulded Objects.
Objectives
By the end of this lesson, you should be able to:
- Mention two ways of preserving moulded objects.
- Explain the importance of preserving moulded objects.
Exhibiting Moulded Objects
Moulded objects are three-dimensional creations made from various materials like clay, wax, or plaster. They can be beautiful works of art, functional tools, or even historical artifacts.
What is Preservation?
Preservation refers to the process of protecting and maintaining moulded objects to ensure their longevity and prevent deterioration. There are several methods of preserving moulded objects, and understanding these methods is crucial for ensuring their quality and beauty for years to come.
Preserving Moulded Objects
Some of the most common methods for preserving moulded objects include:
- Varnishing: Applying a coat of varnish helps protect moulded objects from dust, moisture, and wear, enhancing their durability and appearance. Varnish creates a protective layer that seals the surface and prevents scratches or damage.
- Painting: Adding a layer of paint not only adds color but also acts as a protective barrier, preventing the moulded object from deteriorating due to environmental factors. Paint can also help to enhance the object’s aesthetic appeal.
- Keeping in a Dry Place: Storing moulded objects in a dry environment helps prevent mold and mildew growth. Moisture can be detrimental to the integrity of certain materials, causing them to warp, crack, or even disintegrate.
- Wrapping in Plastic: Placing moulded objects in plastic wrap or bags helps shield them from dust and environmental elements, maintaining their original condition. Plastic wrap acts as a barrier against dust, moisture, and air pollutants.
- Displaying in a Cabinet: Placing moulded objects in a cabinet with glass doors protects them from physical damage while still allowing them to be visible. It also reduces exposure to dust and air pollutants.
Evaluation Questions
Now that you’ve learned about preserving moulded objects, let’s see if you can answer these questions:
- What are two ways to preserve moulded objects?
- Why is it important to preserve moulded objects?
- What are some of the potential dangers that can harm moulded objects?
- How can we display moulded objects in a way that protects them?
- What are some examples of moulded objects that you have seen?
Conclusion
Preserving moulded objects is essential for maintaining their quality and longevity. It allows us to appreciate the craftsmanship and artistry involved in their creation and ensures that these objects can be enjoyed for generations to come. Remember to always handle moulded objects with care and use appropriate preservation methods to protect them.
