The Water Cycle - Science

Hurumanu: The Water Cycle

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

Definition:

The water cycle is a never ending process by which water is circulated through the earth and atmosphere through evaporation, condensation, precipitation and Acidification. The suns energy causes water to evaporate from oceans and other bodies of water. 

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. 1 Cup Of Water
3. 2 Drops of Food Colouring 

Steps:

1.  Get a plastic zip lock bag.
2.  Draw the lay out on the bag.
3.  Write the scientific words onto the bag aswell. 
4.  Pour a cup of water into the bag.
5.  Put 2 drops of food colouring into the bag with the water.

Two Images: 

Findings: We haven't found anything out yet but here's what I think will happen. I think in a couple days it will fog up like condensation on the window then after another couple of days it will be back at the bottom of the bag again. 

Conclusion: This experiment was really fun and it makes me anxious and excited to know what will happen and what the progress will look like.
