On Friday we had science and we had to draw the water cycle on a zip lock bag and then we had to put tape on it and go get water and food colouring to put inside of it. when we got the water and food colouring we had to go to Mrs Shehata and get her to tape the bag to the window with the sun on it so it would stay in the sun and evaporate.

Steps
|
Exp 1
Grab the zip lock bag
Grab a pen
Draw a water cycle on the bag
Go see Mr palmer to get the double-sided tape
Put the tape on the bag
Go see Mr palmer for water and food colouring
Get the cold water put it in the bag
Put in the food colouring
Mix in the food colouring with a teaspoon
Take the bag with water and food colouring in it to go and see Mrs Shehata
Get Mrs Shehata to tape the bag to the window very carefully
Then sit on the mat waiting for the next instruction
Exp 2
Grab a zip lock bag
Grab a pen
Draw a water cycle on the bag
Grab some litmus paper
Go see Mr palmer to get the double-sided tape
Put the tape on the bag
Go see Mr palmer for water, food colouring and baking soda
Put water and food colouring in the bag
Pour baking soda in the bag
Give the bag to Mrs Shehata
She will put it on the window to sit there
Wait quietly on the mat.

Conclusion
|
Exp 1
I think the outcome of this experiment will be… I think it is going to take out all of the
food colourings that is put into the bag but it might not because the food colouring might
dissolve over a while but also I do not know.
Exp 2
I think the water in the 2nd bag is gonna fiz up and make the litmus paper change colour.
It will be really fascinating watching it change colour because when the litmus
paper changes it will change very slowly.

Findings:
|
The Water Cycle: Bag 1
|
CO2 Water Cycle: Bag 2
Acid
|
Desert Water Cycle
Bag 3
|
Does it cycle?
| 2 | 3 | no |
Amount of Water
| 3 | 2 | no |
Acidity
| 2 | 1 | no |
Key: Water and acidity amount: 1 = none
2 = small
3 = large
- For bag 1 there was a small amount of cycle
- For bag 1 there was a small amount of changed watercolour
- For bag 2 there was a large amount of cycle
- For bag 2 there a small amount of water.
Conclusion: Today for science we have finished the water cycle experiment because last time we did not do the chart because some people were falling behind. the findings from last time is exactly the same as now I love to science it is my favourite subject.
