Science - 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.  On your plastic bag draw out the layout.
2. After that write write that represent the process of water.
3.  Then pour 1 cup of water.
4. After the water is poured put in 2 drops of blue food colouring.
5. Then display them in a place that the sun will shine on

Findings:

	The Water Cycle: Bag 1	CO2 Water Cycle: Bag 2 Acid	Desert Water Cycle Bag 3
Does it cycle?	Yes	Yes	No
Amount of Water	2	2	2
Acidity	1	2	1

Key: Water and acidity amount: 1 = none 

2 = small drips

3 = large drips

Ice melting cap

  NASA has estimated that the polar ice caps are melting 9% every ten years, which is an extremely alarming rate. If the temperature on earth continues to rise at its current rate t            he Arctic will have no ice by 2040. The Arctic ice cap has decreased since the 1960s  by as much as 40%.
