Lesson Content/Board Summary

Materials and Their Common Uses

Wood

Wood is a natural material obtained from trees. It has been used for centuries in building, making furniture, and as a source of fuel. Wood is valued because it is strong, durable, and easy to work with.

The following are common uses of wood:

1. Wood is used for making furniture such as chairs, tables, and beds.
2. It is used in building houses, doors, and roofing.
3. It serves as firewood for cooking and heating.
4. It is used for making tools, farm implements, and simple machines.
5. It is used in making paper and pulp products.
6. It is useful in making decorative items and carvings.

Metal

Metal is a solid material usually hard, shiny, and strong. It is obtained from ores and is widely used in industries and daily life because of its strength, durability, and ability to conduct heat and electricity.

The following are common uses of metal:

1. Metal is used in the construction of buildings, bridges, and machines.
2. It is used for making cooking utensils such as pots, spoons, and kettles.
3. It is used in making vehicles like cars, trains, and airplanes.
4. It is important in electrical works because it conducts electricity.
5. It is used in making tools, weapons, and industrial machines.
6. It is useful in making jewelry, coins, and ornaments.

Teaching Methods/Instructional Techniques:

Discussion, Lecture, Explanation, Demonstration, Group Work, Question and Answer, Use of Visual Aids

Lesson Keywords

• Wood – natural material from trees used for building and making furniture
• Metal – hard, shiny material obtained from ores used in industries and daily life
• Furniture – movable items like chairs, tables, and beds made from materials
• Construction – process of building structures like houses and bridges
• Durability – ability of a material to last long without damage

Differentiation

Teacher will use real-life examples and visual aids to support all learners. Advanced learners can be tasked to explain industrial uses of wood and metal, while slower learners classify simple objects.

Note for teachers using this lesson plan

Encourage pupils to bring samples of wood and metal objects from their homes in subsequent lessons. Ensure safety when handling metallic objects. Relate lesson to technology and environment.
