Hurumanu - Science: Water Cycle...

Aim: The aim of this blog post is to write about what we have been doing with our science this term...

We have been doing research about the water cycle...
So first we have been making water cycles on a big plastic bag/Ziplock bag so we basically have been drawing a water cycle on two Ziplock bags and what we did with the first one...

( Water Cycle Experiment 1: ) 

Purpose:
To learn about the water cycle and how CO2 can affect the water cycle...

Materials:
Big Plastic Bag…
A 2 ¾  cup of Water… (To Pour inside the Plastic bag…)
Double-sided tape… (To hang on the window)

Steps:
1 To Get A Big Plastic bag and a permanent Marker...
2 Draw the water cycle on the plastic bag and a sun...
3 A cup of water in a Big Plastic bag with a couple of drops of blue food coloring... ( Make Shore not to get it on your clothes… )
4 And stick it on the window where it gets the most sunlight...

Conclusion:
What happened was that it actually created the vapor and it went well...
Because it did create the vapor and it went down as planned but not as fast...
By fast, I mean that it went as planned.


( Water cycle experiment 2: )

Purpose:
To learn about the water cycle and how CO2 can affect the water cycle...

Materials:
Big Plastic Bag… ( Ziplock bag… )
A cup of Soda water… ( Pour inside the Ziplock Bag…)
1 teaspoon of Baking Soda…. ( Pour into Big Plastic Bag with the Soda Water…) to release the carbon dioxide from the Soda water...
A couple of drops from the Blue Food Coloring...
Double-sided tape… (To hang on the window)

Steps:
1 To Get A Big Plastic bag and a permanent Marker...
2 Draw the water cycle on the plastic bag and a sun...
3 A cup of Soda water in a Big Plastic bag with a couple of drops of blue food coloring... ( Make Shore not to get it on your clothes… )
4 Put the 1 teaspoon of baking soda into the Ziplock bag...
5 And stick it on the window where it gets the most sunlight...

Conclusion:
I think that this experiment will succeed with what its suppose to do…
It was supposed to be like an exact water cycle but inside a Ziplock bag…
I think that it will be somewhat close to succesful because I think that it will create some vapor and then pour down back to were it was….

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	1	2
Acidity	1	2

4 things that I noticed:

Bag one.

1. It started to evaporate

2. The color of the liquid started to shine 

Bag two.

1. The litmus paper turned white

2. Other than that it stayed the same

Conclusion:
I predicted that the normal water cycle would be good and that it would create vapor and show how it created slowly...
While the second water cycle with the baking powder and acid... I thought that it would create the most vapor and show how it would create the vapor, I thought it would be slow, but it would be more like a water cycle than the first bag because I thought it was different so., I thought it would change in a different way.
