What is Water Cycle?
What is the Water Cycle? Water on Earth is constantly moving, changing state (from liquid, to gas, to solid) and being recycled. The water cycle describes this journey. There are 4 main stages in the water cycle: evaporation, condensation, precipitation and collection.
Evaporation:
When the sun heats the surface of seas, lakes, rivers and streams, some of the water changes state and becomes water vapour, mixing with the air. Warm air rises so the water vapour rises too.
Condensation:
When the air cools down, the water vapour condenses back into water droplets. These water droplets collect together and form clouds.
Precipitation:
The water droplets in clouds attract other water droplets to them and they grow bigger. When they get too big and heavy they fall to ground as rain. If the air is cold enough the droplets remain frozen and fall as snow or hail.
Collection:
When the water falls to Earth it collects as streams, rivers or lakes. When it falls on land in can filter in to the Earth and become groundwater or it can flow over the land as run off to meet existing bodies of water.

Know more on Water Cycle
Students Area
. List your personal understanding, ideas.
Now that you are familiar with the Water Cycle you will write everything you know about Water Cycle Describe your thoughts or ideas about how to solve the problem. There are not incorrect answers in this step, just feel free to brainstorm your ideas.
2. List what is known. With your team use all the information available in the scenario to list everything that you know about the Water Cycle. You do not have to conduct any research yet. Just use the information given and write the facts that you already know about the Water Cycle.
3. List what is unknown.With your team, make a list about what you do not know and would like to learn. List all the questions you will need to answer to solve the problem. Your team must have at least 5 questions to research or find the answers to.
5. List what needs to be done.
"What should we do?" List actions to be taken, e.g., question an expert, get List possible actions. Work together as a team.
6. Develop a problem statement.
You will be responsible for thinking and choosing one of the questions to solve the problem. A problem statement should come from your analysis of what you know. In one or two sentences, you should be able to describe what it is that your group is trying to solve, produce, respond to, or find out. The problem statement may have to be revised as new information is discovered and brought to bear on the situation.
7. Gather informationUse all the resources available (Internet, library, etc) to research about the problem/topic and find a solution. Use the Google Search Engine that is provided for you, under the Student Resources in this page.
8. Present Findings
Project 1: The learners will present a dramatization or play of the Water Cycle including the main components: 1. The Sun 2. Evaporation 3. Condensation 4. Precipitation 5. Collection or Accumulation.
