Water Cycle

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

Definition:

Water Cycle

The cycle of processes by which water circulates between the earth's oceans, atmosphere and land.

Involving precipitation as rain and snow.

 drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

Scientific words:

• Evaporation. When water is heated by radiant energy it turns into water vapour.
• Transpiration. Evaporation from plants.
• Condensation. When water vapour 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 climate change.

Material:

1. Plastic bag.
2.  Vivid marker.
3.  1 cup of water.
4.  2 drops of food coloring.

Steps:

1. Get a plastic bag .
2.  Get a vivid marker.
3.  Draw on the bag.
4.  Get 1 cup of water.
5. Get the food coloring.
