Science Water Cycle

AIM: TO LEARN ABOUT WATER ON EARTH.

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.

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

Material:

1.  Plastic bag
2.  vivid
3.  water
4.   food colouring
5. baking soda
6. litmus paper

Steps:

1. get your plastic bag and your vivid 
2.  then draw the water cycle on it (Like in my photos)
3.  put 1 cup of water in your bag
4. add 2 drops of food colouring
5.  add one tsp of baking soda
6. then put litmus paper at the top and see if it changes colour.

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	2	2
Amount of Water	2	2
Acidity	1	1

Key: Water and acidity amount: 

1 = none 

2 = small 

3 = large 

Conclusion: Normal water cycle: It was a small cycle and small amount of water.

Water cycle with acid: The bag with baking soda is the same, small amount of water and small cycle.
