The Water Cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Yes	Yes	Yes
Amount of Water	2	2	2
Acidity	1	3	1

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Materials

1. Water/Soda Water

2. Bag

3. Food colouring

4. Litmus Paper

5. Vivid

6. Sand

Steps

1. Get the materials you need from the Teacher

2.  Draw the diagram of the Water Cycle on the bag

3. Label the Water Cycle diagram

4. Get one cup of soda water or water and put it into the bag

5. 2 drops of food colouring into your bag]

6. Hang the bag up on a window (Bag 2 I added Litmus Paper)

 1. Bag 1 cycled water

2. Bag 1 had a small amount of water 

3. The acidity in bag 1 was low

4. Bag 2  cycled the soda water

5. Bag 2 had a small amount of soda water

6. The acidity in bag 2 was high

7. Bag 3 cycled water

8. Bag 3 had a small amount of water

9. The acidity in bag 3 was low

Conclusion

Bag 1 is the water-based bag. Since it was just plain water in there I expected it to condensate. 

Bag 2 was the soda-based bag. Since it was soda I thought the bag would puff up. I didn't expect it to condensate.

Bag 3 was the sand-based bag with little drops of water in it. I didn't actually know Mr Palmer (Science teacher) was going to do this experiment. But if I knew I wouldn't expect it to work since it would be so dry.

The experiment was fun to make as we got to do a lot of it by ourselves. After 2 weeks it was interesting to see all the condensation in the plastic bags and how the Litmus strips had changed colour. Next time when we do this experiment I would want it to be Summer as it would be hot.
