Which of the following materials is classified as strong?

Which of the following materials is typically not sensible for a knife made of?

What type of material is typically used to make a window?

Which of the following options would be considered silly for a common item made of?

Which sorting method is common for classifying materials?

Materials and Their Properties

Properties describe the characteristics of materials, e.g., strength, rigidity, absorbency.
Metals are generally strong materials, while rubber is known for being waterproof or absorbent.
Rigid materials, like bricks, maintain shape and resist bending, unlike flexible materials.
Common types of materials:
- Fabric: usually absorbent, not typically waterproof.
- Ice: can be considered dull in texture and easily breakable.
- Wood: has a dull appearance and is also flexible.

Magnets and Magnetic Properties

Magnetic materials are attracted to magnets (e.g., iron), while non-magnetic materials are not.
Glass is classified as non-magnetic, while iron is a magnetic material.

Material Sorting

Materials can be sorted based on their characteristics:
- Strength: strong (e.g., steel) vs. weak (e.g., paper)
- Flexibility: flexible (e.g., rubber) vs. rigid (e.g., a table)
- Absorbency: absorbent (e.g., fabric) vs. waterproof (e.g., plastic).

Sensibility of Material Usage

Some material combinations are deemed sensible, and others silly:
- Rubber bikes or fabric tables are considered silly since those materials do not suit their functions.
- A window made of glass is sensible while a knife made of ice is silly.

Summary of Sorting Methods

Sorting can be based on appearance, texture, and functional characteristics of materials.
Examples of sorting criteria include whether a material is transparent, shiny, strong, or absorbs liquids.

Reminder

Understand various materials and their common properties to aid in recognizing their appropriate use and sorting characteristics effectively.

This quiz focuses on the key concepts covered in Unit 5 of the Grade 3 Science curriculum. Students will circle the correct answers to test their understanding of materials and their properties. It's an excellent way to prepare for upcoming assessments in the first term.
