Why does a bike slow down when you stop pedaling?

• Magic ✨ (It's not magic!)

• Friction (Think rubbing your hands together)

• Gravity (Pulling you down!)

• The pedals work like remote control

Answer explanation

A bike slows down when you stop pedaling because of friction. Friction is a force that opposes motion, and it comes from the ground, air, and bike parts rubbing against each other. Without pedaling to keep the bike moving, friction gradually slows it down.

Sound travels faster through...

• Air

• Water

• Vacuum

• Solid

Answer explanation

Sound travels faster through water than air because the molecules in water are closer together. This allows sound waves to pass through more quickly compared to air, where the molecules are farther apart.

Which planet in our solar system is known as the "Red Planet"?

• Jupiter

• Mars

• Earth

• Venus

What is the process by which water changes from a liquid to a gas called?

• Condensation

• Evaporation

• Freezing

• Sublimation

Answer explanation

Evaporation is the process where water changes from a liquid to a gas, usually when heat is applied, causing the water to turn into vapor and rise into the air.

What force keeps us on the ground and makes things fall?

• Magnetic force

• Gravitational force

• Frictional force

• Tension

Answer explanation

Gravity is an invisible force pulling everything towards Earth's center, that's why things fall down when you drop them.

Sometimes on a hot day, you see shimmering water on the road, but it's not actually there! What is this called?

• Magic puddle ✨

  (Not magic, but cool!)

• Mirage

• Hot air bubble

  (That's part of how it works!)

• Petrol leak

Answer explanation

When light from the sky travels through this wavy air, it gets bent and tricks your eyes. They see the reflection of the sky (which looks like water) on the road ahead, but it's not really there! It's like a cool illusion created by heat!

Some gases in the air trap heat from the sun, like a blanket. What are these gases called?

• Noble gases

• Air blankets

  (Kind of, but with a special name!)

• Hot air balloons

• Greenhouse gases

Answer explanation

Greenhouse gases trap heat from the sun, keeping our planet warm – like a real greenhouse for plants. But increase in greenhouse gases can trap too much heat, affecting our climate.
