Water Cycle - Hurumanu

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

Definition: Water cycle is a process that the sun is absorbing the water and it going to evaporate and going to the clouds, it's called evaporation. The continues process by which water is circulated throughout the earth and the atmosphere through evaporation, condensation, precipitation and the transpiration of the plants and animals. 

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 of water
4.  2 drops of food coloring

Steps:

1. Grab a plastic bag and vivid pen and wait for the next instruction.
2.  After you get your materials you can draw to your plastic bag
3. Put the 1 cup of water inside of  your plastic bag
4.  Put 2 drops of coloring to your water.
5.  Stick the plastic bag at the window and observe it for a week to see what will going to happen.

Findings:

  I think the water is going to moist on the top of the plastic bag and the water is going repeat evaporation day by day. But if someone poke it maybe the process gone wrong because maybe the water didn't evaporate and just stay like what it is.

Conclusion: 

Today for our science hurumanu we did a new experiment, this experiment is about water cycle, at first i don't know how we are doing a water cycle using a plastic bag and a marker but when we already did the experiment i really enjoy it because i have something the i learn a because of the experiment i get more ideas about water cycle and how it is working. We did that experiment to explain how the water cycle is working and what is it and what are the process that we don't know about water cycle.
