The water around us has been
All the water around is has been here for many, many years. The reason is because the same water is just around a cycle. There are several steps in this cycle. In my opinion, this is a very interesting and fun project to do.

What is the water cycle?

Water is vital for every living thing. When the Sun heats, it causes the water in the oceans, ponds, lakes and even puddles in the street to warm and evaporate. When water is heated, it changes from a liquid to a gas. This gas is called water vapor, and the process is called EVAPORATION. When plants give off water vapor, it's called transpiration. When water evaporates, it rises into the cooler air, collects, and forms clouds. There, the water vapor molecules cool down and change back into liquid water. This is called CONDENSATION. As more and more water vapor cools into the clouds, the water droplets that form the clouds become larger and larger. These droplets get so big that the atmosphere can no longer hold them up. The droplets fall from the sky. PRECIPITATION is the term for the falling, condensed water molecules, which come down as rain, snow, sleet, or hail.


The water cycle is a process that cycles the water from the Earth’s surface to the sky and back down to the surface. The water can have different states during the cycle. It can be liquid (water), solid (ice) and gas (vapor).


1.Clear bowl
2.Plastic wrap
3.small container (plastic cup)
4.Rubber band
5.Small weight


Grab the small container inside the clear big bowl. Without filling the small container, pour a little bit of water into the bowl. Cover the bowl and tight it with the rubber band. Place the small weight on top of the sealed bowl. Now put this somewhere the sunlight can shine on it, like next to a window.
