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:

• 2 ziplock bags,(A4 sized)
• 200ml of water
• Soda water - 50ml
• Litmus paper 
• Vivid Marker
• Baking Soda 
• Blue Food colouring 
•   tape
• 
  

Findings:

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

Key: Water and acidity amount: 0 = none 

1 = small 

2 = large 

Other comments:

The water cycle did cycle, it has a large amount of water and there is no acidity in the water cycle.
Conclusion:

Decomposing

Hurumanu - Decomposing and Recycling

Aim: To learn about the rate that different materials decompose. 

Hypothesis: I think that......

Materials:

1.   Bananas
2.   White styrofoam
3.   Paper/Cardboard
4.   Bread
5.   Test tube (x4)
6.   Test tube stand
7.     Laboratory Rubber stopper
8. water

Steps:

1. Gather materials.
2.   Cut stylophone,bread and banana into pieces.
3.    Then put 4 test tubes into the test tube stand.
4.   Put them in test tube.
5. Add water to the bread.
6. Put the lid of the test tube. 
7.   Wait for the change.

3 weeks	Colour	Change	Observations
Banana	Blue and brown	The colour change before the colour was yellow and green	It has a lot of moulds
Paper	Brown	It´s the same colour
Styrophone cup	white	it´s the same colour
Bread	Blue with spots	The colour used to brownish now it turn in to blue	The bread used to have no blackspot but now there is black spots.
