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

Definition:

The water cycle says how water evaporates from the surface of the earth, and then it rises into the atmosphere, cools and condenses into rain or snow in the clouds, and then it does it again. 

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 colouring blue.  

Steps:

1.  Get the bag. 
2.  Get a vivid. 
3.  Draw on the bag.
4.  Get water and put food colouring. 
5. Hang up and wait.

2. Soda water.
3. Vivid Marker.
4. 2 drops food colouring (colour blue).
5. Hang up.
