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

Purpose
The purpose is to duplicate the process of the water cycle under controlled conditions 

Materials


  • A4 plastic ziplock bags x2
  • 50ml of water 
  • Blue food colouring 
  • Permanent marker 
  • 50ml of Soda water
  • 1 t Baking soda 
  • Litmus paper 
  • Double sided tape. 
Procedures
  1. Get your materials.
  2. Draw a picture of the water cycle on the plastic bag.
  3. Label the parts of the water cycle.
  4. Add 50ml of water into the plastic bag.
  5. Add a few drops of blue food colouring into the water.
  6. Zip up the bag tightly.
  7. Tape the bag to a window.
  8. Get your other bag.
  9. Repeat the drawing steps on your second bag.
  10. Add 50ml of soda water.
  11. Add one teaspoon of baking soda.
  12. Zip up the bag but leaving a small gap.
  13. Put a strip of litmus paper in, leaving it half in the bag and half out.
  14. Make sure the zip lock is closed and securing the paper.
  15. Tape the bag to the window next to the other bag.
  16. Wait for a few days (maybe weeks)
  17. Watch as the condensation builds up.

Findings:




The Water Cycle
Acid Water Cycle
Does it cycle?
YesYes
Amount of Water
12
Acidity
01

Key: Water and acidity amount: 0 = none 
1 = small 
2 = large

 Comments: 
  • The water cycle did cycle, there was a small amount of water and no acidity.
  • The acid water cycle did cycle and there was a large amount of water and a small amount of acidity. 


Conclusion 
If you follow these steps correctly  you will be able to do the experiment successfully and replicate the water cycle process in controlled conditions
