Hurumanu: The Water Cycle

Hurumanu: The Water Cycle

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. plastic bag
2.  water
3. litmus paper 
4. baking soda

Steps

Bag 1

1. Get a ziplock bag and a vivid pen
2. Draw the water cycle (label the parts of the water cycle)
3. Carefully pour 1 cup of cold water
4. Carefully drop 2 drops of blue food colouring
5. Stick the ziplock bag in a window where it receives sunlight.

Bag 2

1. Get a ziplock bag and a vivid pen
2. Draw the water cycle
3. Carefully pour 1 cup of cold water
4. Carefully drop 2 drops of blue food colouring
5. Carefully put 1 teaspoon of baking soda
6. Stick the ziplock bag in a window where it receives sunlight

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid
Does it cycle?	2	1
Amount of Water	3	2
Acidity	0	2

Key: Water and acidity amount: 1 = none 

2 = small 

3 = large

Conclusion:

what I learned is new words evaporation condensation and transpiration
