Do you know where your water comes from?

Recently, my cub scout den was working on their Engineering Webelo Activity Badge and we made a visit to our town's water department. (This is a photo of the collage we generated about water after our visit and given to the Water Department as a thank you gift for taking the time to meet with us.) I'm not sure what the boys got out of the experience, but I sure learned a lot. Here in New England, the majority of people get their water out of the ground via wells (the same is true for our town). Once the water is pumped up, the pH levels must be adjusted, and then chlorinated. It was fascinating to see how the whole system works. We learned that to work in the Water Department you need to be knowledgeable with mechanics (machinery does break down from time to time), chemistry (the handling and fine balancing of chemicals), geology, computers (the whole system is monitored by computers), and law (a myriad of state and federal laws and regulations governing the use and "production" of water). Today, we take for granted that when we turn on the faucet something will come out and that it will be safe to drink. It certainly is a lesson for all of us to know the behind the scenes process that make our lives so comfortable. (Hint: watch the Discovery Channel's Dirty Jobs show sometime.) Maybe our next field trip should be to the Waste Water Treatment Facility - what goes in must come out.

Project WET-The Incredible Journey Water Cycle Game

This fall I had the opportunity to attend a teacher workshop sponsored by Projects WET, WILD and Learning Tree held at the Beaver Brook Association located in Hollis, NH. My fellow participants and I enjoyed a fantastic day conducting and learning how to teach environmental science in the perfect outdoor setting.
Recently, I used one of the workshop activities called "The Incredible Journey," in the classroom. The fourth graders I was working with had just begun a unit on the water cycle. First, we generated a list of where we can find water. Then I introduced the "Incredible Journey" activity and sent them off on their own water journey. Pictured here is their "journey journal." At each station they placed a colored bead on their lanyard to record where they had been. After 25 minutes of journeying we stopped to discuss where their journey had taken them. In this example, the journey of this water molecule began (the right side of the picture) in a plant (green bead), which then evaporated to the atmosphere through the process of transpiration, condensed into a cloud (white), snowed onto a glacier (yellow), melted into ground water (orange), flowed into a lake (purple), which flowed into a river (dark blue), which flowed into the ocean (light blue), where it stayed for a while (now why would that be?), evaporated into the atmosphere and became a cloud again (white), rained into a lake (purple), was drunk by an animal (red), which urinated (the kids kind of thought that was gross), then seeped into the soil (black), which was absorbed by the roots of a plant (green), which was lost through transpiration to the atmosphere (white), which is where this story began but which will continue and continue and continue which of course is the whole point!!! (Sorry for the run on sentence.) As a follow up activity, the students were asked to imagine that they were a water droplet and to write a descriptive tale of their journey based on their beaded record. Needless to say, the kids had a blast with this activity.

Audubon's 107th Christmas Bird Count 12/14-1/5

Beginning tomorrow, December 14th the Audubon Society begins its annual Christmas Bird Count. Visit www.audubon.org/bird/cbc/index.html to learn more about this event and how you might be able to participate. What a great way to expose students to the concept of observation and how this data is used by scientists. You might consider setting up a feeder or two around the school to study the winter habits of birds in your area!!
