Can You Find the Dripline? | Foster

Last month, in lieu of the rain, the students at Foster Elementary and I reviewed the Water Cycle and how the earth recycles and reduces the water through evaporation, condensation & precipitation. Together, we looked at a picture illustrating this repetitive pattern: water evaporating from the ocean to the air (leaving the salt behind), condensing into a cloud in the sky, traveling over inland and precipitating in the mountains as snow/rain, traveling downhill into streams and lakes and underground reservoirs, and finally returning to the ocean to be recycled again.  We even sang a song to let these steps sink into our long term memory.

Then, we took a moment to realize that Los Angeles doesn’t get much rain so we really need to be mindful of our water use. Shorter showers, less flushing, turning off the facet when not in use, etc. I then showed the students that in the garden, we are water-wise through our use of drip irrigation. I explained how these hoses, with 12-inch emitters, slowly drip water on the ROOTS of the plants when the timer tells them to.

The students then got a chance to watch this technology work. I turned on the water and the kids looked for the water drip, drip, dripping from the hoses. Where the water pooled, we planted a bean seed. It was an eye opening experience for us all to be aware of water usage and our climate.
