Water Cycle- Science

Hurumanu: The Water Cycle

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

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.

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 bag
2.  Vivid Marker
3.  1 cup water
4.   2 drops of food colouring
5. Litmus paper ( only for the soda water )

Steps:

1. First thing you have to do was to get a plastic bag and get a vivid pen.  
2.  The second thing you do was you have to draw on the plastic bag.
3.  The third thing you have to do was put water on the plastic but not too much.
4.  After you have put the water in your plastic bag you need to put food colouring  on it but only 2 drops
5. The last thing you have to do was to stick the bag on the window.

Two Images:

         

Findings: 

In my opinion the water will moist in the bag and it will be a bit foggy in the top, and I also think the water will became less - Evaporation.

For the second there would be more air forming in the plastic bag because when you blow a balloon it will fill up with air, if we did this right the yellow paper will became red.

Conclusion: 

In science my group told me that they we're looking at the water cycle, and they learn 4 new words that was about evaporation.They did some research and the have to find out the definition of the water cycle and they have to include the new 4 words that they had learn. In their experiment they include a lot of stuff like the zip lock bag, in the zip lock bag they have to draw the water cycle in the drawing there a piece of a land, in that land there a tree, it has ocean,clouds, the sun, and the rain. It look's really fun doing this experiment and I want to learn more about it.

In the second one it was also the same but there's  a special paper called Litmus paper and when we check it the paper will become red.
