I learned that objects around us are made from different materials, and we can group them based on common properties like material, color, shape, hardness, or shine. Grouping helps us to understand things better and compare them easily.

Activity 6.3: Let us think (Page 104)
Let us think what materials we can use to make a tumbler. Fill in the names of the materials in the spaces provided in Fig. 6.2. (See Textbook, Page 104)

Answer: To make a tumbler, the material used should be able to hold liquids like water, milk, or juice without leaking. It should be non-porous, which means it should not allow liquid to pass through.

Some materials that can be used to make a tumbler are:

• Glass

• Plastic

• Stainless steel (metal)

• Aluminum

• Copper

We cannot use materials like cloth, paper, or sponge because they are porous and will leak or get soaked when filled with liquid.

Conclusion: A tumbler must be made of materials that can hold liquids without absorbing or leaking them. So, hard, non-porous, and waterproof materials are suitable for making tumblers.

Activity 6.4: Let us Explore (Page 105)
Fig. illustrates a variety of balls that are of the same size but made up of different materials.

Answer: 

Table: Bouncing Level of the Balls

Observation:
Balls made of different materials bounce to different heights. For example:

• The tennis ball bounces the highest.

• The cricket ball bounces the least.

• The hand exercise ball and rubber ball show medium bounce.

Activity 6.5: Let us Observe (Page 107)
Hold the objects given in Table 6.3 with your hands. Feel whether the objects are hard or soft. Find out the materials they are made up of. Enter your observations in Table 6.3.

Answer: 

Objective: To observe whether given objects are hard or soft and to identify the materials they are made from.

Materials that can be easily pressed or scratched are considered soft, while those that cannot be easily pressed or scratched are considered hard.

Table: Classification of Objects as Hard or Soft

Conclusion: Objects can be hard or soft depending on the type of material they are made of. Hard objects are strong and cannot be pressed easily, while soft objects can be pressed or squeezed with little effort.

Activity 6.6: Let us Classify (Page 109)

Classify the following objects as transparent, translucent or opaque in Table.

Answer:

Objective: To classify objects based on how much light they allow to pass through — as transparent, translucent, or opaque.

• Transparent materials let light pass through clearly.

• Translucent materials allow some light but not clear images.

• Opaque materials do not allow any light to pass through.

Table: Classification of Objects

Conclusion: Objects can be grouped based on their ability to allow light to pass through. This property helps in deciding how materials are used — for example, transparent materials for windows, opaque for doors, and translucent for lampshades.
