Title

How to make a water cycle...

Purpose

To learn about the water cycle and how the CO2 affects the water cycle.

Materials

2 zip lock Bags Pen Water Food colouring Fizzy Tape. Baking soda Table spoon Teaspoon A cup of water

Steps

Steps: 1st bag: Get  a zip lock bag Get a pen/ draw the water cycle on your bag Pour hot water into the bag Put 2 or 3 drops of food colouring Put 2 teaspoons of baking Soda Pour some fizzy into the bag for the water to create the water cycle. To experience the water cycle, tape the bag to a window so the sun can shine on it and the experience will happen. 2nd bag: Get another zip lock bag Draw the same picture on your zip lock bag Put a Tablespoon of baking soda into the bag. Pour water into the Zip bag Put 2 or 3 drops of food colouring Pour some fizzy into the bag. Get some tape. Tape the zip lock bag on the window, facing the sunlight.

Findings:

bag 1 hod a small amount of water and the cycle had the same amount of of water but small

and the acidity had no bubbles or acids what so ever.

bag 2 had a small amount of cycle  and the water was small almost nothing and the acidity was huge it was everywhere.  

Key: Water and acidity amount: 1 = none 

2 = small 

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

Conclusion:

The normal water cycle
hod a small amount of water and the cycle had the same amount of of water. The . acidity had no bubbles or acids what so ever. and the acidity was huge it was everywhere.
