Experiment 1:

Step 1:

Grab your Zip lock bag.

Step 2:

Grab a vivid pen.

Step 3:

Draw the water cycle on the zip lock bag with the vivid.

Step 4:

Step 7:

Close the zip lock bag and give it to the teacher to stick on the glass
window where there is sun shining on. 

Experiment 2:

Step 1:

Findings:

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

For bag 1 it did a small amount of the water cycle and it also had a small amount of water.

For bag 2 the water cycle was no change at all and the water didn't change. 

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Conclusion:

The normal water cycle did have a little movement through the cycle and the water stayed the same.

The water cycle with acid didn't do anything to the litmus paper and the water stayed the same as well.
