Three days and counting (yes, we even left them out as we anticipated guests, because the learning was just that amazing). Couldn't stop progress!
Day one, a Civil War camp was erected. Yesterday, a pulley system brought water to the soldier's camp.
Today, a catapult was designed. Three sisters, different ages, working together. Asking questions. Collaborating. Problem solving. Once in awhile, I hear, "Mom, will this work?" Though I feel somewhat limited in my engineering abilities, working together we were able to figure out a solution.
In the midst of the process, in an effort to help my daughter understand the science behind a catapult, I found a video about potential and kinetic energy. The contents moved mind gears in a different direction. I wonder if I will find a roller coaster in my living room tomorrow?
