Question 1

What is a water molecule?

Accepted Answer

A water molecule is the smallest piece of water you can have. It's made of two hydrogen atoms and one oxygen atom stuck together like a tiny LEGO set.

Question 2

Where does a water molecule start its journey?

Accepted Answer

A water molecule can start its journey almost anywhere there's water, like in the ocean, a river, a cloud, or even in the ground.

Question 3

How does a water molecule travel through the water cycle?

Accepted Answer

A water molecule travels through the water cycle by changing forms. It might evaporate into a cloud, fall as rain, and flow into a river or ocean.

Question 4

What is evaporation?

Accepted Answer

Evaporation is when a water molecule gets hot and turns into a gas, floating up into the sky to become part of a cloud.

Question 5

What happens when a water molecule condenses?

Accepted Answer

When a water molecule cools down, it can turn back into liquid, which is called condensation. This is how clouds make raindrops.

Question 6

How does a water molecule return to the ground from the sky?

Accepted Answer

A water molecule comes back to the ground when it rains, snows, or hails, after it condenses in the sky.

Question 7

Can water molecules move underground?

Accepted Answer

Yes! Water molecules can seep into the ground and join underground rivers or become part of the water supply plants drink.

Question 8

How does a water molecule get into our bodies?

Accepted Answer

We drink water or eat foods with water, and the water molecules enter our bodies, helping us stay healthy.

Question 9

Can a water molecule go into the ocean?

Accepted Answer

Yes, water molecules can end up in the ocean by flowing in rivers or as part of the rain that falls directly into the ocean.

Question 10

Why does a water molecule become rain?

Accepted Answer

A water molecule becomes rain when lots of water droplets in a cloud get too heavy and fall to the ground.

Question 11

How do plants use water molecules?

Accepted Answer

Plants suck up water molecules from the ground with their roots to help them grow and make food.

Question 12

Can water molecules freeze?

Accepted Answer

Yes, when water molecules get really cold, they slow down and stick together tightly to become ice or snow.

Question 13

What is the role of the sun in the water cycle?

Accepted Answer

The sun heats up water, causing it to evaporate into the sky and power the whole water cycle like a giant engine.

Question 14

How does a water molecule travel through rivers?

Accepted Answer

A water molecule moves along in rivers, carried by the flow of the water until it reaches a lake or ocean.

Question 15

What is a cloud made of?

Accepted Answer

Clouds are made of tiny water droplets or ice crystals that gather together in the sky.

Question 16

Can water molecules be inside animals?

Accepted Answer

Yes, animals drink and absorb water, and the water molecules travel around to help their bodies work properly.

Question 17

How long does it take for a water molecule to complete the water cycle?

Accepted Answer

The journey can be really quick or take thousands of years, depending on where the molecule goes, like into the ocean or deep underground.

Question 18

Can a water molecule ever leave Earth?

Accepted Answer

Most water molecules stay on Earth, but a very tiny number might get picked up by space when they are in the air.

Question 19

Are the water molecules we drink today the same ones from the past?

Accepted Answer

Yes! Some of the water molecules we drink are the same ones that dinosaurs drank long ago because of the recycling nature of the water cycle.

Question 20

What's fun about the journey of a water molecule?

Accepted Answer

The exciting part is that water molecules can travel everywhere, from deep oceans to high in the sky, experiencing many cool adventures along the way!
