I have shown my children how the water cycle works using just a plastic bag and a glass with water.
They were very surprised with the results!!.
 |
| We prepare the plastic bags... |
 |
| drawing the water cycle on them!! |
 |
| We put a glass with water and food colouring inside. |
 |
| Be sure you leave air inside before closing the bag!! |
 |
| Place the bag on a window and wait for the sun to heat it... and evaporation will take place!. |
 |
| After a few days... |
 |
| the water evaporated is in the bag in form of liquid water... |
