Science (The Water Cycle)

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

Definition:

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

Steps:

1.  Draw Clouds, Rain, Island, Trees And Sun 
2.  Add The Scientific Names Of The Steps In The Water Cycle
3.  Add Water And Food Colouring Together (Fill 2/10 Of The Bag)
4.  Leave On A Wall (Tape On) And Dont Touch It For A Week
5.  Watch The Condensation Grow Slowly Check Every Week (Make Sure You Dont Touch The Bag)

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Yes	Yes	Yes
Amount of Water	2	2	2
Acidity	1	2	1

Key: Water and acidity amount: 1 = none 

2 = small drips

3 = large drips

Comments:

Bag 1: Had A Good Cycle With Little Drops Of Water And It Had No Acidity 

Bag 2: Had A Great Water Cycle With Drops Bigger Than Bag 1 But The Drops Were Still Small      (Bag 2 Had Acidity)

Bag 3: Had An Average Cycle With Small Drops And No Acidity BUT... It Had Sand At The Bottom Bring Water Out Of The Sand Making The Sand Dryer
