AIM: TO LEARN ABOUT WATER ON EARTH.

Definition:

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 SONG

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.  Vivid
2.  2x Bags
3. 1/2 Water 
4.  1 tbsp of baking soda

Steps:

1.  Draw your water cycle
2.  Carefully add the water
3.  If your doing the acid one, add 1 tbsp of baking soda and litmus paper at the top
4.  Add some food colouring
5. Wait at least 2 - 3 wks

Two Images:

Findings:

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

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large 

Conclusion:

The normal water cycle had less condensation than the other. The normal bag didn't have any Baking soda involved

The water cycle with the acid, had changed the colour of the litmus paper to red after it started out blue.
