Science - Water Cycle

Aim : TO LEARN ABOUT WTHE 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. Vivid
2. Plastic bag
3. Cold water
4. Blue food colouring
5. A person to draw the water cycle
6. Baking soda
7. Litmus paper

Steps

Exp1

1.  Get one Plastic bag 
2. Get one vivid 
3. Draw the Water cycle one time on the plastic
4. Go to the teacher
5. Put 3 cm of water cold water
6. Put 2 drops of blue food die 
7. Close the bag 
8. Get two pieces of double-sided tape
9. Give the bag to the teacher 
10. Hang it up on a window that has sunlight

Exp2:

1. Get one Plastic bag 
2. Get one vivid 
3. Draw the Water cycle one time on the plastic
4. Go to the teacher
5. Put 3 cm of water cold water
6. Put 2 drops of blue food die 
7. Put one teaspoon of baking soda
8. Get one piece of litmus paper
9.  Close the bag 
10. Get two pieces of double-sided tape
11. Give the bag to the teacher 
12. hang it up on a window that has sunlight

Two Images:

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

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Conclusion:

Exp1.

I think the outcome of this experiment will be, I think the bag will turn out a different colour to show that it is working. Or the blue food colouring will disappear out of the bag because of the water cycle.

Exp2.

I think the same for this experiment it will either the colour will disappear. The food colouring will change colour. There is baking soda in the second experiment I think that the water will disappear out of the bag.

First we draw the water cycle on the bag and then we filled up with water and then we put food diet and we close the bag and we got double-sided tape we put it on there for a while and then we took it off and then we gave it to me she harder to hang it up on the window that has somewhat so the water cycle would start to work.
