1. Why are handspans not used as a standard unit of measurement?
Standard units like the metre are needed so that results remain the same for everyone.
Click to view answer
Handspans differ in size from person to person, so they do not provide a consistent measurement.Standard units like the metre are needed so that results remain the same for everyone.
2. Define a reference point in the context of motion.
It helps determine if an object has changed its position over time.
Click to view answer
A reference point is a fixed object or point with respect to which the distance or position of an object is stated.It helps determine if an object has changed its position over time.
3. Differentiate between hard and soft materials.
Soft materials can be easily compressed or scratched, like an eraser or sponge.
Click to view answer
Hard materials are difficult to compress or scratch, such as stone or iron.Soft materials can be easily compressed or scratched, like an eraser or sponge.
4. What is condensation? Give one natural example.
The formation of dew drops on leaves in the morning is a common natural example.
Click to view answer
Condensation is the process of conversion of water vapour back into its liquid state upon cooling.The formation of dew drops on leaves in the morning is a common natural example.
5. How is common salt obtained from seawater?
The water turns into vapour, leaving behind solid salt which is then purified.
Click to view answer
Seawater is collected in shallow pits and left in the sunlight for the water to evaporate.The water turns into vapour, leaving behind solid salt which is then purified.
SECTION D: Long Answer Questions (2 x 4 = 8 Marks)
1. Explain the three main types of motion with one example each.
Circular motion: Object moves along a circular path, like a stone whirled at the end of a thread.
Oscillatory motion: Object moves to and fro about a fixed position, like a child on a swing.
All these motions are classified based on the path the moving object follows.
Click to view answer
Linear motion: Object moves along a straight line, like a student marching in a parade.Circular motion: Object moves along a circular path, like a stone whirled at the end of a thread.
Oscillatory motion: Object moves to and fro about a fixed position, like a child on a swing.
All these motions are classified based on the path the moving object follows.
2. Describe the process of the Water Cycle.
Water evaporates from oceans and land, rises into the air, and cools to form clouds via condensation.
The tiny droplets in clouds combine and fall back to Earth as rain, snow, or hail.
Finally, the water flows through rivers back into the oceans, and the entire process repeats.

The water cycle is the continuous circulation of water between the Earth's surface and the atmosphere.Water evaporates from oceans and land, rises into the air, and cools to form clouds via condensation.
The tiny droplets in clouds combine and fall back to Earth as rain, snow, or hail.
Finally, the water flows through rivers back into the oceans, and the entire process repeats.
SECTION E: Case Based Questions (2 x 4 = 8 Marks)
Case 1: Ghulan came home tired and thirsty. His mother mixed sugar, salt, and lemon juice in a tumbler of water to make lemonade. Ghulan noticed the sugar and salt disappeared after stirring. Later, he saw water droplets on the outside of the cold glass.
Q1. What term is used for materials that disappear when mixed in water? (1M)
Q2. Name the process responsible for droplets on the outside of the glass. (1M)
Q3. Why did the salt disappear? Explain in two lines. (2M)
A3: Salt is soluble in water, meaning its particles spread out and mix completely with water molecules.

Case 2: Padma was visiting her grandparents in Delhi. She saw kilometre stones reading 'Delhi 70 km' and later 'Delhi 60 km'. This helped her understand her position relative to her destination.
Q1. In this scenario, what serves as the reference point? (1M)
Q2. Which SI unit is used for measuring long distances between cities? (1M)
Q3. How did Padma know she was moving? Explain in two lines. (2M)
A3: Her position relative to the reference point (Delhi) was changing with time as shown by the stone readings.
