Water Cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Definition:

The water cycle is a process that when water is being evaporated by the sun. It then gets into the clouds and then when the cloud gets to heavy the water insides fall down. This is a never ending cycle.

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• Transpiration. Evaporation from plants.
• Condensation. When water vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the waters falls as rain, sleet, hail, or snow.
• Acidification: the action or process of making or becoming acidic.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.

THE WATER CYCLE EXPERIMENT

Bag 1: Normal Water cycle

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Bag 3: Water cycle with ice added: like Antarctica in climate change

Bag 1: Normal Water cycle

Material:

1.  Plastic bag
2.  Vivid Marker
3.  1 cup of water
4.   2 drops of food colouring

Steps:

1.  On your plastic bag draw out the layout.
2. After that write write that represent the process of water.
3.  Then pour 1 cup of water.
4. After the water is poured put in 2 drops of blue food colouring.
5. Then display them in a place that the sun will shine on.

Bag 2: Water cycle with CO2 added: like Oceans in climate change

Material:

1.  Litmus paper
2. 1 cup Soda Water
3. Plastic Bag
4. Vivid marker
5. 2 drops of food colouring

Steps:

1.  Fold a little bit of litmus paper and fold it inside the plastic bag.
2. On your plastic bag draw out the layout.
3. After that write write that represent the process of water.
4.  Then pour 1 cup of soda water.
5. After the soda water is poured put in 2 drops of blue food colouring.
6. Then display them in a place that

Findings:

	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	2	1

Other Comments:

Bag 1

1. Bag 1 had cycled normally.
2. The water in bag 1 formed in small drops
3.Water cycle in Bag 1 had no acidity.
Bag 2
1. Bag 2 had a normal water cycle.
2. The water formed small drops like bag 1.
3. Bag 2 had more acidity than bag 1.
Bag 3
1. Cycled normally.
2. Had the same small drops of the other bags.
3. Had less acidity that bag 2 and the same as bag 1.

Conclusion:
Bag 1,2 and 3 all had the same amount of small drops formed. All of them also cycle normally. Bag 1 and 3 had less acidity that bag 2.
