Water cycle

Grade 4 · Science · Free lesson

Hi there! I am Studyfin, your science friend. Let us explore how water moves all around our world!

The water cycle is the way water moves from Earth up to the sky and back down. This cycle never stops, and it keeps our planet healthy.

investigation

First, the warm sun heats up water in lakes and oceans. The liquid water turns into an invisible gas called water vapor and rises up. This is called evaporation.

Evaporation

Next, the warm gas cools down high in the air. It turns back into tiny water drops that crowd together to form clouds. This is called condensation.

Condensation

When clouds get too heavy, the water falls back to the ground. This is precipitation, which we see as rain or snow. Now, let us compose a quick poem to help us remember these stages!

Precipitation
✏️ Worked example

Let us think like an author! We will write a short poem about a raindrop to show its journey. Then, we will explain the purpose of our poem.

  1. Step 1: Choose the topic and genre. We are writing a poem about the water cycle.
  2. Step 2: Compose the lines. Let's write: 'I start in the lake, so cool and blue. The sun warms me up, and I rise like new! I float in a cloud, then fall as rain. I slide to the lake to start over again.'
  3. Step 3: Check the genre elements. Our poem has rhyming words (blue/new, rain/again) and a steady beat.
  4. Step 4: Explain the author's purpose. The purpose of this poem is to teach readers about the water cycle in a fun, creative way.
