Water cycle

We was studing the water cycle!

To carry out this experimet we just needed a bag, water, a pen and some dye!

If you put the bag in a window, with the temperature of the sun, we can study the evaporation and the condensation of the water.

If you put the bag into the freezer you can study the transformation from liquid to solid (Freezing), and if you put the bag out to the freezer againg, you´ll study the  melting!
