Summer is my favorite time of year. I love being in and around the water. Throughout college I taught swimming lessons. Some kids could float while other could not… even after learning the proper technique. I did not know it at the time but, this can all be explained by learning the principle of floatation, known as Archimedes Principle. John Ingalls, a marine engineer who works for the Navy and his son Cobb, helped us to learn why things stay afloat. We got to see a Cardboard Boat Race in Lunenburg, MA held by the local library. Making your own boat and racing it looked like a lot of fun!! Many thanks to all involved! |
