In lieu of the impending rain, I taught the students at Foster about the Water Cycle. With the clouds in the sky above us, and the breeze occasionally swirling, we got to observe the change of weather in action!
The water cycle is a beautiful process in which our earth reuses water. It begins over a body of water, such as the ocean. As the sun heats up the water, water molecules turn from liquid to gas; they evaporate into the air. This water vapor ascends towards the sky, collecting closely, creating clouds through condensation. The cold air cannot hold the water, so the vapor appears as puffy cotton. As the kids and I discussed, clouds don’t actually feel like anything… They’re only wet. (You can try it by holding your hand in front of your breath!)
Finally, when the humidity (measure of water in the air) has reached 100%, the clouds become so heavy that the water falls from them, precipatating into rain, snow and the like. This water eventually returns to the body it originated and the process begins again.
The kids thought it is crazy that the same water we use to brush our teeth is the same water that existed when the dinosaurs were around!
We sang a song to remember all the steps of the water cycle and then the kids helped me to spread mulch in the pathways to prevent the dirt areas from getting muddy and the grassy areas from growing grass during this rainy season.
We’re looking forward to seeing how the water will continue to beautify the garden as well as greater LA.
