The Water Cycle: Why Is It a Tricky Concept?

Updated: Jun 11


Understanding the water cycle can be challenging for children, as it involves grasping how water changes states between solid, liquid, and gas. To help your child effectively learn this concept, it's important to use engaging strategies that make these transitions clear and relatable. In this guide, we'll summarize the key stages of the water cycle and explain the changes of state that water undergoes, providing you with practical tips to support your child's learning journey.


Change in state of water


Water can change from one state to another when it gains or loses heat. These processes are the following: boiling, freezing, melting, evaporation and condensation


 

Boiling


Boiling is the change in the state of water from liquid (water) to gas (steam) due to heat gain. The temperature at which water boils is called the boiling point. The boiling point of water is 100 degree Celsius.



Freezing


Freezing is the change in the state of water from liquid (water) to solid (ice) due to heat loss. The temperature at which water freezes is called the freezing point. The freezing point of water is 0 degree Celsius.



Melting


Melting is the change in the state of water from solid (ice) to liquid (water) due to heat gain.The temperature at which ice melts is called the melting point. The melting point of Ice is 0 degree Celsius.



Evaporation


Evaporation is the change in the state of water from liquid (water) to gas (water vapour) due to heat gain. Water can evaporate at any temperature above room temperature. Room temperature is about 20 to 25 degree Celsius.



Condensation


Condensation  is the change in the state of water from gas (steam/water vapour) to liquid (water) due to heat loss. Steam is hot water vapour at 100 degree Celsius. Like water vapour at any other temperature, it condenses when it meets a cooler surface.



Test your kid’s familiarity with the concept


You can test your kid’s familiarity with the water cycle concept by using one of our exercises below.
