Air and Sound Science

Well, I suppose since my career involves sound, it only makes sense that I help Olivia with her Sound Science lessons. :) We talked about sound travelling in waves and how it has to move through a medium like air, water or even the ground. Some of the experiments we did involved seeing how sound waves can cause ripples in a glass of water (a la Jurassic Park), feeling sound vibrate a balloon, hearing how making a string tighter or looser changes the pitch and making an old-fashioned string telephone.

Olivia has been learning about some of the inventors of the 1800s and early 1900s. One of those was Alexander Graham Bell and the telephone. It was certainly a nice connection between history and science.

We also did some air experiments showing the power of wind.

We saw how a sail can make a boat move.
We saw how the air in a balloon can make it shoot across a room.
Even Gabe got into it. :)
