There were many cools things about the visit to the Ridgewood Reservoir. In addition to being a beautiful place to be on a misty day, kids got to trace their drinking water's trip from the Ashokan...their camp site...to this former site of the Brooklyn reservoir. Students used drinking straws to construct an aqueduct system, one team at a time. Then they joined their systems into one; superimposing it on top of a large map of the NY State water shed.
(As an aside: This blogger learned that her drinking water came from this Reservoir up until the late 1950s. And that someone's grandmother remebered swimming there! Yikes!)
Fifth graders know that renewable sources of energy such as wind and solar energy will be around long after coal or other fossil fuels are used up. They also know that renewable energy has its challenges. Here they are using wind generators and solar cells to power motors and lights.
Not enough wind...have to run to make enough electricity to light the bulb.
Getting the right angle helps get electrons flowing.
Too cloudy for solar cells. Too still for wind. Time to run.
