Unit OverviewThe following unit is based around Inquiry Learning. Students explore where our water comes from and how much we have on the earth. Students build a greater understanding of the water cycle, the different places we find water, how much water is available for humans to readily use and the three different states of water.
BackgroundThe water cycle is the continuous movement of water between the land, bodies of water and the atmosphere, and it is a very important element of life on earth.
When rain falls from the sky, the water can do one of several things. It can be used by trees and plants and subsequently be transpired to the atmosphere as water vapour; it can flow over the land as run-off and enter streams, lakes or the ocean; it can soak into the ground, join the ground water table and eventually make its way to streams, lakes or the ocean; or it can evaporate from the ground upon which it falls.
In any case, the end result is always evaporation, with the rising vapour condensing in the sky to form clouds, and the clouds providing more rain.
Did you know?
All the water on earth is all the water we’ll ever have and it’s been this way since the earth was formed. There are three states of water, which are recycled over and over again through a continuos process known as the Water Cycle. This means that the water we use now could be used by our great, great, great, great, great grandchildren!

Keywords & Definitions
The following keywords & definitions will be explored throughout this unit. In order for students to become familiar with the terminology the keywords and their definitions can be used as ‘words of the week’. Have students write out the keywords and definitions and put them up in the classroom or write them on the board for easy reference.
Atmosphere: The layer of gases that make up the air around the earth
Condensation: Water vapour rises into the air and cools, it turns into water droplets, forming clouds, mist and fog.
Dissolved: When a solid has mixed with a liquid and a new liquid is formed.
Evaporation: Is the process that describes water changing from a liquid to a gas.
Ground Water: All subsurface water, generally occupying the pores and crevices of rock and soil.
Precipitation: Water dropping from the sky as rain, snow, hail or sleet.
Runoff: Water that travels over the surface of the earth.
Seepage: Water that soaks or seeps into the soil and the earth.
Surface Water: Includes rivers, lakes, oceans, sea - water that you can see.
Transpiration: The plant takes water from the ground, through the plant and out the leaves.
Water Cycle: The cycle of water on planet earth.
Water Vapour: The process that describes water changing from a gas to a liquid.

Activity One: Introducing the water cycle
Overview:Students learn the terms and processes of the water cycle by researching the definitions and processes.
Duration:1 hour
Equipment: Various resources to research the terms of the water cycle including books and the internet

Blackboard or whiteboard
Activity: The water cycle1. Ask students a set of questions to stimulate students thinking of the water cycle. To find out where
they think the water in the rivers, creeks and taps comes from.
2. Questions to ask students could include:
a) Where does the rain in our rivers, creeks, dams and lakes come from?
b) When we turn on our taps, where does this water come from?
c) What happens to water on a very hot day? Where does the water go? Think about a puddle or when you water a plant.
d) When it rains where does the water go?
3. Draw a K.W.L table, like the one shown below on big pieces of butcher’s paper.
4. Explain to students that as a class they are now going to make a plan to investigate where their water that they use everyday comes from.
5. Ask students to write in their workbooks the sentence “Where does the water in our rivers, creeks, dams and taps come from?” Under this sentence ask the students to list facts about the topic that they already know. Explain that they will not be tested on these answers and it is just to get them to start thinking about the topic and how much they already know.
6. Once the students have completed the first step, ask them to select one point that they have recorded to share with the class, without repeating what has previously been said. Write the points up on the butcher’s paper under ‘What I Know’. Add any additional points from students not already listed.
7. Next again ask the students to write in their workbooks the sentence “Where does the water in our rivers, creeks, dams and taps come from?” Under this sentence students write down some questions that they want to find out about the topic. There is no such thing as stupid questions. Students should be encouraged to look for broad ideas, rather than having a narrow focus.
8. Again ask the students to select one point that they have recorded that they want to share with the class, without repeating what has previously been said. Write the points up on the butcher’s paper under ‘What I Want to know’. Add any additional points from students not already listed.
9. Explain that the final column will be completed once they have completed their unit on the water cycle. When you return to complete this section, advise students that this section is a chance to think about what they have learnt while studying the water cycle.
10. Discuss some of the points students have listed up on the board about what they know and what they want to know.

11. Introduce students to the concept of the water cycle by drawing a diagram of the water cycle (online examples include: http://cd7.e2bn.net/e2bn/leas/c99/schools/cd7/website/images/bp-watercycle2.jpg or http://community.seas.columbia.edu/weatherstation/glo/images/diag_water_cycle.gif) on the board and listing the terms of the various aspects of the water cycle.

Activity Two: Have we seen this drip before?
Overview:Students build their understanding of the water cycle and that it is a continuous process that has been happening for millions of years. They do this through researching the water terms and labelling the water cycle diagram.
Duration:Part 1: 45 minutes
Equipment: Various resources to research the terms of the water cycle including books and the internet

The Silent Card Shuffle Picture Cards (page 6)
Activity: Part 1: The never ending cycle of water1. Students are to use the internet, books or other resources to find out what the terms of the water
cycle mean. Ask the students to design a recording sheet to record information that helps answer their question and the websites where the information was located. Some great websites include:
a) The Water lili website
b) http://www.olliesworld.com/planet/aus/index.htm
c) http://www.water-ed.org/kids.asp
d) http://www.watercare.net/wll/wc-watercycle.html
2. Bring the group back together and dicuss the various aspects of the water cycle, and how it gets recycled over and over again, as it has been doing for millions of years.
3. Print out a copy of the Black Line Master on page 61 of the Water Live It Learn It resource (Each School should have a copy of this resource, or contact North East Water [email protected]) for students to fill in and label the components of the water cycle diagram, or conduct the Silent card shuffle activity.
Part 2: The silent card shuffle water cycle1. Break students into small groups of 3 or 4 and each group a set of cards. Explain to students that
without talking they need to sort the cards to represent the process of the water cycle (this could be done in a line from top to bottom or in a flow chart). They can use actions to communicate but they are not allowed to talk and all members of the team should contribute. Explain that there are no wrong answers they just have to agree on the order.
2. After groups have finished placing the cards in order allow the groups to discuss amongst themselves about their decisions, explaining that they will need to explain their reasons to the other groups.
3. Regroup students and discuss in turn where students thought the water cycle process started and finished. Discuss how the process is ongoing with no real start or end, and that there are no wrong answers, as it’s a never ending process.

Activity: Part 1: Water makes a statement
1. Ask students what the three states of water are and write them up on the board in a table
2. Prompt students with examples of the three states and include examples under each of the three headings.
3. Discuss with students how each state of water is turned into another state i.e. boil liquid to make steam turning liquid to a gas, freeze liquid water to make a solid ice cube, leave a solid ice cube in the sun until it melts to a liquid etc.
4. Have students conduct some experiments to explore the three different states of water that are apart of the water cycle.
Example of the states of water table
Topic: The three states of water
Liquid Gas Solid
Rain Running water Lakes, rivers & dams Dew
Vapour Steam Cloud Mist & fog
Ice & icebergs Snow Hail Frozen liquids (iceblock)
Activity:Part 2: The water cycle experiments
a. Set up the room with separate stations for each of the experiments students will be undertaking. Each station should include a heading of which aspect they are conducting, instructions and the necessary equipment (see below).
b. Explain to students how to undertake each experiment, asking students which experiments they think correspond to which aspect of the water cycle
c. Give each student a worksheet that they can work through whilst undertaking each experiment or complete at the end.
d. Break students into groups – one group for each of the stations except for one. This will allow groups who finish experiments quicker to go on and complete another experiment.
e. Students are to rotate through the experiment stations, setup and undertake each experiment.
f. Students will need to observe some experiments throughout the day and later record their results.
