water cycle

AIM: TO LOOK AT THE WATER CYCLE AND HOW CLIMATE CHANGE IS AFFECTING IT.

Definition:

The water cycle is continuous water going from the sea to sky to the land and back to the sea

Scientific words:

Evaporation. When water is heated by radiant energy it turns into water vapour.

• Transpiration. Evaporation from plants.
• Condensation. When water vapour 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.

We will be conducting an experiment that looks at the different ways that climate change is affecting the water cycle.

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. Ziploc bag  
2. Vivid market 
3. 1 cup of water 
4. 2 drop of food colouring  

Steps:

1. get into a group of 3
2. get materials 
3.  the water cycle on Ziploc bag
4.  get 2 drops of blue food colouring
5.  add 1 cup of water
6. tape the Ziploc bag on a window with lots of sun sring on it

Two Images:

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

Key: Water and acidity amount: 1 = none 

2 = small drips

3 = large drips

Other comments:

Bag 1 :

1: the water cycle in bag 1 had no acidity

2: the water  cycle  does cycle

3: the water cycle in bag 1 has little drops of water  

Bag 2 : 

1: the water cycle in  bag 2 has acidity

2: the water  cycle in bag 2   does cycle

3: the water cycle in bag 2 has little drops of water

Bag 3 :

1: the water cycle in  bag 3 has  no acidity

2: the water  cycle in bag 3   does cycle

3: the water cycle in bag 3 has little drops of water

in all three bags, there are little drops of water and the water cycle is going. 

Icecap melt.

 the ice there is getting thinner and melting smaller, and cracking, which is destroying the habit of all the animals and people that live there. Also, the increased amount of melted ice is causing the ocean levels to rise about 23 feet! 

Climate change:

The mass of the ice sheet has begun to decline
