NO CLASS NOVEMBER 22, DECEMBER 20. 11/1-12/13: Geocaching: The old-fashioned scavenger hunt goes high-tech with our geocaching unit. We'll start with the basics of compass and directions, and progress to handheld GPS units. This may soon be a family favorite activity in your home. 1/3-1/31: The Great Inventors: We'll recreate the wheel and many other inventions from the past. Galileo, Benjamin Franklin, Alexander Graham Bell and Leonardo DaVinci left us enough science for hundreds of hands-on experiments. We won't do that many, but we'll try!
