Science - Water cycle

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

Definition:

The water cycle describes how water evaporates from the surface of the earth, rises 

into the atmosphere, cools and condenses into rain or snow in clouds, and falls again 

to the surface as precipitation. The rain that falls on the ground or land collects in rivers and lakes and soil and most of I goes back in the oceans, where it will once more evaporated. The cycling of water in and out of the atmosphere is a significant aspect of the weather patterns on Earth.

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 land

 Material:

1 Plastic bag 

2 vivid marker 

3 One cup of water 

4 2 drops of food colouring 

Steps:

1. Get in a group of three and then get a vivid marker and ziplock plastic bag.
2. Then you draw clouds, the sea, sun, rain and trees.
3. After that you then pour your one cup of water into the ziplock bag.
4. When the water is poured in then you add two drops of food colouring in the water.
5. Then finally you put them in a sunny place for a few days.
   Here is Two Images of what we drew.

Here is the materials and steps to bag 2 -

 Material:

1 Plastic bag 

2 Vivid marker 

3 One cup of soda water 

4 2 drops of food coloring 

 Steps:

1. Get in a group of three and then get a vivid marker and zip lock plastic bag.
2. Then you draw clouds, the sea, sun, rain and trees.
3. After that you then pour your one cup of soda water into the zip lock bag.

4. When the water is poured in then you add two drops of food coloring in the water.
5. Then finally you put them in a sunny place for a few days and watch what happens. 

We used soda water because it has carbon dioxide in it and we wanted to know what would happen if there was any difference in it or too it.
