Climate Chaos

This week we did a google doc about an experiment we had done in science last week. In science we are talking about water cycle and how it works and what it does. Last week we got in groups of no more then three ,in my group was Briannna and Talia. In my google doc it explains the materials, how we did it, the steps, our goal and what I think the out come would be etc. Here it is :

Title	How to make a water cycle bag
Purpose	To show the water cycle To show the water cycle with baking soda dioxide
Materials	First bag 1 plastic zip lock bag 1 vivid 1 cup of warm water 2 drops of Blue food coloring 2 small pieces of double sided tape Second bag  1 plastic zip lock bag 1 vivid 1 cup of warm water 2 drops of Blue food coloring 2 small pieces of double sided tape 1 tsp Baking soda Small piece of litmus paper
Steps	First bag .First you get your plastic zip lock bag and a vivid .Secondly you draw the water cycle on the front of your plastic zip lock bag .You then put the two small pieces of tape on the top and bottom center of the bag .Next you go  to the teacher and get about 1 cup of water and 2 drops of food coloring .Now you zip the bag up and hang it somewhere it can get light ( window, glass door etc. ) Second bag .First you get your plastic zip lock bag and a vivid .Secondly you draw the water cycle on the front of your plastic zip lock bag .You put the two small pieces of tape on the top and bottom center of the bag .Next you go over to the teacher and get about 1 cup of water, 2 drops of food coloring and 1 tsp of baking soda. .You will give the bag a little swirl around to mix the baking soda with the water .Now you zip the bag up and hang it somewhere it can get light ( window, glass door etc. )
Conclusion	I think the outcome of this experiment will be ….. First experiment : I think that nothing will happen because I think there is nothing that would cause this to have a reaction , but if it were going to do something I think the most it would collect more water off the windows. Second experiment : I think maybe the water will rise up the bag and turn into carbon dioxide and disappear or turn to air . What really happened :

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Small - Bag 1 cycles and you can see that it does.	Small - Bag 2 cycles and you can also see it and the effect it had which wasn't much.
Amount of Water	Small - There is still a decent amount of water in the bag.	Small - There was still a lot of water left in the bag.
Acidity	None	Small - There is a little bit of change and the litmus paper had changed color to blue.

Conclusion : In conclusion Bag 1 didn't change much but still had a little bit of an effect and Bag 2 had changed the color of the litmus paper and it had a little change. I think bag 2 had a bigger effect because there was backing soda in it that let out gas.
