Hurumanu - Science: Water Cycle

Science

The past few weeks we have been doing Science, we have done 3 experiments so far. 

Our first one was where we had to draw the water cycle onto a plastic bag and then add all these things into the bag and also did another one for 2 big added more things. 

Climate Chaos

Title	The water cycle
Purpose	To see how the water cycle works
Materials	Ex1. Vivid  Plastic bag Cold water Blue food die A person to draw the water cycle  Ex2. Vivid  Plastic bag Cold water Blue food die A person to draw the water cycle  Baking soda  Litmus paper
Steps	Get one Plastic bag  Get one vivid  Draw the Water cycle one time on the plastic Go to the teacher Put 3 cm of water cold water Put 2 drops of blue food die  Close the bag  Get two pieces of double-sided tape Give the bag to the teacher  hang it up on a window that has sunlight Exp2.  Get one Plastic bag  Get one vivid  Draw the Water cycle one time on the plastic Go to the teacher Put 3 cm of water cold water Put 2 drops of blue food die  Put one teaspoon of baking soda Get one piece of litmus paper  Close the bag  Get two pieces of double-sided tape Give the bag to the teacher  hang it up on a window that has sunlight
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.

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Small - Bag 1 did cycle. I give this a 2 = small because it did show the cycle but not a big amount of it.	Small - Bag 2 doesn't cycle, I choose a 2 for this one because it didn't really cycle  but still had a fair enough amount  of water left over.
Amount of Water	Small - There is still a small decent about of water left in the bag.	Small - There was still heaps of water left over in the bag.
Acidity	None - because it had no Acid in it.	Small- There was a little bit of acid in there it works sort of and changed the colour of the paper we put into the bag.

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Conclusion: In bag 1 after waiting couple weeks to see if anything changes, bag 1 did show the water cycle but I gave it a 2 ( Small ) because didn't have a big amount of it showing, but for water cycle 2 it didn't show the water cycle as much as bag 1 did but did still have a fair enough of water left over so I give it a 2, I really enjoyed this as was fun to do and learn about our water cycle.
