📌 Key Concepts

✦ Objects are made of materials (wood, metal, plastic, glass, etc.)

✦ Lustrous = shiny surface (metals); Non-lustrous = dull surface

✦ Hard (diamond, iron) vs Soft (cotton, sponge)

✦ Transparent (glass), Translucent (oiled paper), Opaque (wood, metal)

✦ Soluble = dissolves in water (salt, sugar); Insoluble = doesn't dissolve (sand, oil)

✦ Conductors allow heat/electricity to pass; Insulators do not

✦ Same material can make different objects; same object can be made from different materials

Q4 What are transparent, translucent, and opaque materials?
ANSWER

Transparent: Materials that allow all light to pass through. Objects can be seen clearly. Example: Glass, water, air.

Translucent: Materials that allow some light to pass. Objects appear blurry. Example: Oiled paper, frosted glass.

Opaque: Materials that allow no light to pass. Objects cannot be seen through them. Example: Wood, metal, brick.

Q5 How can the same material be used to make different objects?
ANSWER

A single material can be shaped or processed into many different objects.

Example: Wood can make a table, chair, door, bat, pencil. Metal (steel) can make spoon, knife, utensils, car parts, bridge.

Q6 Can the same object be made from different materials? Give examples.
ANSWER

Yes! The same object can be made from different materials depending on the purpose.

Example: A plate can be made from steel, glass, plastic, paper, or banana leaf. A chair can be made from wood, metal, or plastic.

Q7 What is the difference between hard and soft materials?
ANSWER
Hard MaterialsSoft Materials
Difficult to scratch or compressEasy to scratch, compress, or bend
Diamond, Iron, Stone, GlassCotton, Sponge, Rubber, Wool
Q8 What are conductors and insulators?
ANSWER

Conductors: Materials that allow heat and electricity to pass through. Examples: Iron, Copper, Aluminium, Silver.

Insulators: Materials that do not allow heat and electricity to pass. Examples: Wood, Rubber, Plastic, Glass.

Why it matters

Electrical wires use copper (conductor) inside and plastic (insulator) outside for safety.
