Water x Water x Water

Description

Water is all around us! It is in our ocean, lakes, rivers, and streams. It is also inside our bodies and in the air we breathe.

Water comes in three states:

LIQUID

GAS

SOLID  


By changing its state, water moves all around the earth in the Water Cycle

Starting as a liquid, water Evaporates into a gas which forms the clouds in the sky. As a gas in the clouds, water goes through Condensation to turn back into a liquid. When there is enough liquid in the gassy clouds, it falls to the earth as Precipitation (rain). Sometimes when the air around it is cold the water forms a solid rather than a liquid and falls to the earth as SNOW!

If you look at water under a very strong microscope, you would see that it is made up of molecules. Each molecule in water is made up of 3 little pieces: 2 hydrogen atoms and 1 oxygen atoms. This is why it is called H2O = 2 hydrogen atoms and 1 oxygen atom. These molecules are the puzzle pieces that together make up the large bodies of water we know.

These molecules are always moving. When the molecules move really fast, water turns into a gas. When the molecules slow down, water becomes a solid. Because of this, water can change from a gas to a solid to a liquid and back again. It is never stuck in one state. Where do the molecules get the energy? From HEAT!

You can try it at home! With adult supervision, put some liquid water into an ice cube tray and pop it into the freezer. In the freezer it is very cold because there is not very much heat. This means there is not very much energy. The cold causes the molecules to move very slowly which freezes the liquid water into solid ice!

Now take some liquid water and put it into a pot over the stove. Have an adult turn on the stove and carefully watch happens to the water. You will see the water begin to boil and steam will rise into the air. The steam is water in its gas state. The heat from the stove caused the molecules to move really fast, evaporating the liquid into a gas.

Now you know everything there is to know about water!


Task

Using the comic strip template attached to the assignment, draw a story about a water droplet as it journeys through the water cycle!

Does your water molecule start in the clouds or in the ocean? Does it land on mountains or on the dessert? Does it fall as snow or as rain? Remember all water will always return back to the ocean, usually through rain or by being carried by rivers or streams.

Upload an image of your epic water cycle comic to the Video Gallery

ALTERNATIVES; For younger grades, draw a singular picture 

  • Students could draw what water looks like in their place 
  • Students could collectively make a story - record with pictures if it meets their abilities 

Once you have made a submission for the assignment, your badge will appear the next time you log-in

Learning Objectives

To understand the different states of water and how their changes drive the water cycle that connects all the earth to the ocean.

This activity may be used to support the following learning objectives and competencies 

GRADE: Primary,  Intermediate 

BIG IDEAS

K: the motion of objects depends on their properties 

K: Daily and seasonal changes affect all living things 

1: Observable patterns and cycles occur in the local sky and landscape

1: Matter is useful because of its properties 

2: Water is essential to all living things, and it cycles through the environment

3: Wind, water, and ice change the shape of the land

3: all matter is made of particles 

4; Matter has mass, takes up space and can change phase

4: Energy can be transformed 

5: Earth materials change as they move through the rock cycles and can be used as natural resources (interaction between geosphere and hydrosphere)
