Did you know 75 % of Earth is made of water?
In Science, we have been learning about the stages of the Water Cycle. Water is found in many places such as lakes, rivers, oceans, ponds, puddles, reservoirs, and many other places.
The first stage is evaporation. This is a process where the water is heated and turned into a water vapor. The sun is the main heat source for this process. 
Following the evaporation stage is condensation. This is where warm and cold air collide and form ice crystals that condense and form droplets of water.
These water droplets eventually become too heavy and begin to fall in the form of rain, snow, hail or sleet. This stage is called precipitation.
The next stage is percolation. The water seeps through the soil and ends up in the water table. It then flows into the streams, lakes, oceans, and other bodies of water. The process is then repeated again and again. 
We even made our own models of the Water Cycle:
