Hurumanu: The Water Cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Definition:

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• Transpiration. Evaporation from plants.
• Condensation. When water vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
• Acidification: the action or process of making or becoming acidic.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Bag 3: Water cycle with ice added: like Antarctica in climate change

Material:

1.  Water/Soda Water
2.  Bag
3.  Food Colouring
4.   Litmus Paper

Steps:

1.  Get the Marker and the Bag from the teacher
2. Draw the water cycle on the bag 
3.  Go up to get 1 cup  of water or soda water 
4.  Put 2 drops of food colouring
5. Hang the bag up on the window

Two Images:

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Yes	Yes	Yes
Amount of Water	2	2	2
Acidity	1	3	1

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Other comments:

1. Bag 1 Cycled water
2. Bag 1 had a small amount of water
3. Bag 1 had none Acidity
4. Bag 2 Cycled Water
5. Bag 2 Had a small amount of water
6. Bag 2 had a large amount of Acidity
7. Bag 3 Cycled
8. Bag 3 had a small amount of water
9. Bag 3 Had none Acidity

Conclusion:

Bag 1  Had Cycled water, Had a small amount of water and had no Acidity.

Bag 2 Cycled water, Had a small amount of water and Had a large Acidity.

Bag 3  Cycled the water, had a small amount of water and had no Acidity.

Draw a labelled diagram of the Water Cycle

Water cycle words:

10. Flooding

SOLO Hexagons Activity

TODAY YOU WILL BE INVESTIGATING THE EFFECTS THAT CLIMATE CHANGE HAS ON THE WATER CYCLE.

1. Using your SOLO hexagons poster write a paragraph about the different aspects of climate change.
2. Write about the following Climate Change concepts:

You can do these by powerpoint, embedding a movie , on your blog, on a doc or any other form of presentation. It is up to you.
