After evaporation we have condensation. When the water vapor reaches the sky it cools to form clouds.

Finally, a precipitation experiment. Again, fill a cup almost full with water.

Explanation:

Matter is conserved because atoms are conserved in physical and chemical processes. As complex as the water cycle is, water molecules are conserved and endlessly recycled in nature. Conservation of mass is a physical law that s never broken.
