THE WATER CYCLE

Activity 1

CAN YOU GUESS HOW OLD IS IT? MAKE A GUESS!

“The water in this glass may have fallen from the rain last week, but the water has been here, around us, for billions of years.  The mass of water on Earth remains fairly constant over time, but water moves from one reservoir to another. This continuous movement described by the water is known as “Water Cycle” and involves different physical processes obtaining different states of water”.

Let's think all together about how the water cycle works! We're going to brainstorm together on terms we need to describe the trip of the water contained inside that glass of water around the Earth.

Activity 2

We've watched at one molecule of water completing the hydrologic cycle. Heat from the sun causes the molecule to evaporate from the ocean's surface. Once it evaporates, it is transported high in the atmosphere and condenses to form clouds. Clouds can move great distances and eventually the water molecule will fall as rain or snow. Ultimately, the water molecule arrives back where it started...at the ocean.

-Review the meaning of evaporation, condensation, precipitation, and accumulation.

-Teach the students the song and incorporate hand motions.

-Sing the song with students and do the hand motions.

-After watching these videos, pupils will have to complete the filling-gap exercise with regard  to “Water Cycle Song” Lyrics

Activity 3

After watching this video, students will be asked to work in groups and they will have to answer the questionnaire,

talking to each other using the new vocabulary and getting the grammar reasonably right.

Activity 4

Write a short piece on the new concepts of this lesson.

Students will need to write using the new vocabulary, using some of the phrases for classifying and some connectors which show clarity in their writing.

The text lenght will be around 130 words.
