Question 1

What is a water molecule?

Accepted Answer

A water molecule is the smallest part of water. It's made up of two hydrogen atoms and one oxygen atom.

Question 2

How does a water molecule become rain?

Accepted Answer

A water molecule becomes rain when water in rivers, lakes, or the ocean gets warm, turns into vapor, and goes up into the clouds. When the clouds get too heavy, they release the water as rain.

Question 3

What happens to a water molecule after it falls as rain?

Accepted Answer

After rain falls, a water molecule can sink into the ground or flow over the land. It often joins streams or rivers, traveling further.

Question 4

How does the water molecule get to a river?

Accepted Answer

A water molecule travels downhill in streams and brooks to larger rivers. Gravity helps pull the water downhill.

Question 5

Can a water molecule stay in one place?

Accepted Answer

Not usually. Water molecules are always moving. They can stay in one place like a puddle for a while, but they usually keep traveling because of rain, gravity, and the sun.

Question 6

What makes water molecules move from one place to another?

Accepted Answer

Water molecules move because of the sun and gravity. The sun heats the water, making it rise, and gravity pulls it downhill when it rains.

Question 7

Can water molecules be part of something else besides rain and rivers?

Accepted Answer

Yes, water molecules can be in the air, in oceans, in plants, and even in our bodies. They're everywhere water is found.

Question 8

Why do water molecules go up to the clouds?

Accepted Answer

When water is heated by the sun, it changes into vapor and rises into the sky. This is because warm air is lighter than cold air.

Question 9

What do water molecules do in the clouds?

Accepted Answer

In the clouds, water molecules group together to form bigger drops. When these drops get big enough, they fall as rain.

Question 10

Can a water molecule become a snowflake?

Accepted Answer

Yes, if it's cold enough, a water molecule can turn into ice and become part of a snowflake.

Question 11

What happens to water molecules in rivers?

Accepted Answer

In rivers, water molecules flow along the river's path. They can travel long distances, sometimes even reaching the ocean.

Question 12

Can a water molecule return to the ocean?

Accepted Answer

Yes, many water molecules in rivers eventually reach the ocean, where they can start their journey all over again.

Question 13

Do all water molecules travel the same path?

Accepted Answer

No, water molecules can take many different paths. Some might stay in soil, get absorbed by plants, or evaporate into the air again.

Question 14

Can water molecules be cleaned as they travel?

Accepted Answer

Yes, as water molecules move through soil and rocks, they can get filtered and become cleaner.

Question 15

Why is it important for water to move around the Earth?

Accepted Answer

Water moving around the Earth brings fresh water to places that need it. This helps plants grow and provides drinking water for animals and people.

Question 16

How can a water molecule be in the plants?

Accepted Answer

Plants take water molecules from the ground through their roots. The water travels up the plant and helps it grow.

Question 17

Can water molecules help animals?

Accepted Answer

Yes, drinking water keeps animals healthy by helping them stay hydrated. Water also helps in food digestion and temperature control.

Question 18

What is the water cycle?

Accepted Answer

The water cycle is the journey of water molecules from the ocean to clouds, then raining back to rivers and into the ocean again. It's like a big circle that keeps repeating.

Question 19

How does temperature affect water molecules?

Accepted Answer

Temperature can make water molecules move faster or slower. When it is warm, they move more and can become vapor; when it is cold, they can freeze into ice.

Question 20

Can water molecules change into something else?

Accepted Answer

Water molecules always stay water, but they can be liquid, vapor, or ice. These changes happen because of temperature differences.
