Hello, students! Welcome back to Primary 5 Basic Science And Technology. In our previous lesson, we learned about No previous lesson found.. Today, we’re going to learn about Materials & Maintenance.
Objectives
By the end of this lesson, you should be able to:
- Define metal.
- List out 5 types of metal, their uses, and examples.
Materials & Maintenance
What is Metal?
Metal is a substance known for its high electrical conductivity, luster, malleability (can be molded or bent), and ductility (can be stretched into wires).
Types of Metal
Some of the major types of metal include:
- Iron – Use: nails, Example: nails
- Copper – Use: wires, Example: electrical wires
- Aluminum – Use: beverage cans, Example: soda can
- Gold – Use: jewelry, Example: necklace
- Silver – Use: coins, Example: dime
- Lead – Use: batteries, Example: car battery
- Zinc – Use: galvanizing, Example: galvanized iron
- Tin – Use: food containers, Example: canned soup
Evaluation Questions
Now that you’ve learned about Materials & Maintenance, let’s see if you can answer these questions:
- What is the definition of metal?
- Can you name two types of metal and their uses?
- List an example of an object made from metal.
- What are some of the properties of metal? 5. Why is it important to understand different types of metals?
Conclusion
In this lesson, we learned about the definition of metal and explored some of the common types of metal, their uses, and examples. Remember, metals are essential materials in our daily lives, and understanding their properties is crucial for various applications.
