Hurumanu 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 SONG

Title: The Water Cycle Experiments

Purpose: To help you learn about the water cycle so you know what the teacher is talking about in science class.

Materials:

• 2 x A4 sized zip lock bags.
• Vivid marker
• Litmus paper
• 50mls soda water
• 50mls water
• Baking soda
• Blue food colouring
• 20cm double-sided tape (10cm per bag)
• teaspoon

Procedures:

1. Draw the earth with a mountain and land with plants on the land (leave a place for the sea/ocean) (Lable what they are)
2. Draw clouds and water vapor going into the sky also add it coming down (Lable what they are)
3. Repeat the previous two-steps on the other bag.
4. Open one of the bags and put 50mls of water into the bag.
5. Add two drops of blue food coloring into the bag with water in it.
6. Zip the bag up and tape it to a window.
7. Open the second bag and add 50mls of soda water into the bag.
8. Add one teaspoon of baking soda to the soda water
9. Add two drops of blue food coloring to the soda water bag.
10. Put Litmus paper at the top of the bag and zip it up.
11. Tape it to a window.

Findings:

	The Water Cycle	Acid Water Cycle
Does it cycle?	2	2
Amount of Water	2	1
Acidity	0	1.5

The normal water cycle did cycle well and there was heaps of water but had zero acidity in it.

The acid water cycle did cycle and there was a bit of water but not too much and had some acidity that wasn't that much to be a two but was still heaps

Key: Water and acidity amount: 0 = none 

1 = small 

2 = large 

Other comments: 

our water cycle experiment worked and I really enjoyed it.

Conclusion: 

The normal water cycle did cycle well and there was heaps of water but had zero acidity in it.

The acid water cycle did cycle and there was a bit of water but not too much and had some acidity that wasn't that much to be a two but was still heaps.

My water cycle experiment worked and now I know how to do the experiment now.
