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
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:
- Ziploc bag
- Vivid market
- 1 cup of water
- 2 drop of food colouring
Steps:
- get into a group of 3
- get materials
- the water cycle on Ziploc bag
- get 2 drops of blue food colouring
- add 1 cup of water
- tape the Ziploc bag on a window with lots of sun sring on it

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
