The water Cycle

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

Definition:

The Cycle processes by which water circulates between the Earths ocean's, atmosphere and land involving precipitation as it rains and snow. It will eventually evaporate then it will condense and return to the atmosphere by evaporation and transpiration. 

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapor.
• 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.  Plastic zip lock bag
2.  Marker
3.  1 cup of water
4.  2 drops of food colouring
5. litmus paper
6. soda water

Steps:

1.  Find your group of 3
2.  Get materials  
3.  Draw the water cycle on the bag
4.  Put 1 cup of water in the bag
5.  Put 2 drops of food colouring in the bag of water

Findings:

Conclusion: The water cycle is basically the earths cycle. Its goes round and round with Evaporation, Condensation, precipitation and transpiration. The water cycle is water from the sea because then it will evaporate and it will go into the clouds then it will come back when it rains. I will have more of an conclusion and findings when we next have science.

For the second bag we used soda water. We used soda water because it has carbon dioxide in it so it will create moisture in the bag. We put a piece of litmus paper in the bag so over a few days it will turn into a orange ish red colour. The litmus paper changes colour because of the carbon dioxide. It starts of yellow and it will change into red when the carbon dioxide comes out of the soda water and it will create moisture, then it will go into the litmus paper and turn it into red.
