Properties of Metals Worksheet - Grade 5 - South Africa - Free Printable

Problem Description:

The task involves matching the properties of metals listed in the worksheet to their correct definitions. The properties are: soft, hard, malleable, ductile, high melting point. The definitions provided are:

1. Can be drawn into thin wires.
2. Goes from a solid to a liquid under high temperatures.
3. Able to be hammered and shaped.
4. Firm and resistant to pressure.
5. Reflects light.

Solution Explanation:

#### Step 1: Understand Each Property
- Soft: Metals that are soft can be easily deformed or cut with minimal force.
- Hard: Metals that are hard are firm and resistant to deformation or pressure.
- Malleable: Metals that are malleable can be hammered or pressed into different shapes without breaking.
- Ductile: Metals that are ductile can be stretched or drawn into thin wires without breaking.
- High Melting Point: Metals with a high melting point require a lot of heat to change from a solid to a liquid state.

#### Step 2: Match Definitions to Properties
Now, let's match each definition to the appropriate property:

1. Can be drawn into thin wires.
- This describes the property of being able to stretch or draw into thin wires without breaking. The correct property is ductile.

2. Goes from a solid to a liquid under high temperatures.
- This describes the temperature at which a metal changes from a solid to a liquid state. The correct property is high melting point (since metals with a high melting point resist this change until very high temperatures).

3. Able to be hammered and shaped.
- This describes the ability to deform under pressure without breaking. The correct property is malleable.

4. Firm and resistant to pressure.
- This describes the property of being hard and not easily deformed. The correct property is hard.

5. Reflects light.
- While this is a property of metals, it is not explicitly listed in the given options. However, if we were to include it, it would relate to the metallic luster of metals. Since it is not one of the listed properties, we will focus on the others.

#### Final Matching:
- a. Can be drawn into thin wires → ductile
- b. Goes from a solid to a liquid under high temperatures → high melting point
- c. Able to be hammered and shaped → malleable
- d. Firm and resistant to pressure → hard

Final Answer:

\[
\boxed{
\text{a. ductile, b. high melting point, c. malleable, d. hard}
}
\]
