After learning all about the ear and how we hear the second graders began the study of color and sight. Once again, they did many experiments to see how light travels and how prisms work. They even learned how to write their names in Braille. The highlight of this unit was when members of the Contra Costa Dog Raisers visited our class. They gave us a short lecture about preparing puppies to become guide dogs for the blind. We also presented our donation of $355.00 which we raised from our school bake sale.
