Welcome, class! Today, we’re going to learn about the Water Cycle. Can anyone tell me what they think the Water Cycle is?
Is it about how water moves around the Earth?
Exactly! The Water Cycle describes how water evaporates, condenses, precipitates, and collects. It’s a continuous process. Can anyone name one of the stages of the Water Cycle?
I think evaporation is one of them!
Great job! Evaporation is indeed the first step where the sun heats water to turn it into vapor. We can remember the stages using the acronym 'ECPCR', which stands for Evaporation, Condensation, Precipitation, Collection, and Runoff. Let's discuss each stage in detail.
The first stage is evaporation. How does it happen?
The sun heats the water!
Exactly! Water from oceans and lakes heats up and transforms into vapor. Now, what happens next?
It forms clouds when it cools down, right?
That's correct! This process is called condensation. Can anyone think of a way to remember evaporation leads to cloud formation?
Maybe 'Hot turns to Cloudy' could work?
I love that! Always remember, hot conditions lead to cloud formation. Let's summarize so far: we have evaporation leading to condensation.
Now let’s move on to precipitation. What do you think happens after condensation?
The water falls back to the ground?
Exactly! This falling water is called precipitation and can be in the form of rain, snow, or hail. After precipitation, what happens?
Water collects in rivers, lakes, or oceans?
Correct! This is what we call collection. It’s essential for maintaining water sources on Earth. Now, let's recap: evaporation → condensation → precipitation → collection.
We’re almost at the end of the Water Cycle! After water collects, what can happen next?
Water can either run over the surface or seep into the ground!
Exactly! This is called runoff and infiltration. Runoff is when water flows over land into rivers and lakes, while infiltration is when water seeps into the soil, replenishing groundwater supplies. Let’s review all five stages together.
ECPCR: Evaporation, Condensation, Precipitation, Collection, and Runoff!
Fantastic! You've mastered the Water Cycle. Remember, it's a continuous cycle that keeps our planet hydrated and balanced.
Process where liquid water turns into vapor.
Water vapor cools and forms clouds.
Water falls back to Earth as rain, snow, etc.
Water gathers in bodies such as lakes and rivers.
Movement of water on the surface and into the ground.
The water goes up, then down with a splash, like a fun game of flow, in a constant dash.
Once there was a happy drop of water named Wally. Wally loved to rise into the sky, dance in the clouds, fall back as rain and join rivers on a great adventure!
ECPCR - Evaporation, Condensation, Precipitation, Collection, Runoff - helps remember the Water Cycle steps.
WATER - Water Always Travels Even Round, highlights the ongoing nature of the Water Cycle.

The continuous movement of water within the Earth and atmosphere.
The process by which water changes from a liquid to a vapor.
The process where water vapor cools and transforms into liquid, forming clouds.
Water released from clouds in the form of rain, snow, sleet, or hail.
The gathering of water in rivers, lakes, oceans, or underground.
Water that flows over the ground back into bodies of water.
The process by which water seeps into the soil.
The Water Cycle describes the continuous movement of water through evaporation, condensation, precipitation, collection, and runoff.
The Water Cycle, also known as the Hydrological Cycle, outlines the stages of water circulation on Earth. It includes evaporation of water into vapor, condensation into clouds, precipitation back to Earth, collection in bodies of water, and runoff that returns to the atmosphere or the ground.
The Water Cycle, or Hydrological Cycle, is the process through which water circulates continuously between the Earth’s surface and the atmosphere. This cycle plays a crucial role in sustaining ecosystems and regulating climate. The main stages include:
This cycle not only illustrates the movement of water but also helps maintain life and ecological balance.
