I ended the year with an exploration of music. I used xylophones, pendulums and windchimes to explore frequency, wavelenght, pitch, volume, etc. I probably should have found a way to incorporate physical waves, but a trip to the beach was out of the question and I met disaster in my attempts at building a wave pool. We did, however, create a pretty sweet 2×4 xylophone and frame.
Make it safe & keep the rubber side down this weekend.
