Hurumanu: The Water Cycle

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

Definition: the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in9 streams and rivers, 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 vapor cools, molecules join together and form clouds.
• Precipitation. When clouds get heavy the water 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 (blue)

Steps:

1.  Get the bag
2.  Get a vivid marker
3.  Draw on the bag
4. Get  1cup of water  
5. Get food coloring 

Two Images:

Findings:

Conclusion: for our science we did a science solo thing We had  10 hexagons and order them on a big paper. So we started with evaparation, freash water, carbon Dioxside,oceans,water vapor, condensation,precipitation,stormsand flooding 

(Bag 2)

       

1. Litmus paper
2. Soda water
3. 2 drops of food colouring 
4. Vivid marker
