======Exploration of Sound====== Today we began class by experimenting with some tuning forks. Emily provided lots of tuning forks for the students to play with:\\ \\ {{:days:winter2012daybyday:winter2012day9:tfork.jpg}}\\ \\ {{:days:winter2012daybyday:winter2012day9:tfork2.jpg}}\\ \\ The students created a list which included observations and questions that they came up with throughout their exploration time with the tuning forks:\\ {{:days:winter2012daybyday:winter2012day9:list.jpg}}\\ \\ Their **observations** included:\\ * You can see the vibrating of the tuning fork. * When you place a tuning fork on a solid object, the noise stops. * When you touch the tuning fork to hair near your ear, it sounds like a bumble bee! * There are numbers and letters on the sides of the tuning fork. * Holding your hand on the bottom of a "hollow" tuning fork changes the sound.\\ \\ Their **questions** included:\\ * Does the size of the tuning fork matter? * What happens if you put the tuning fork in water? //After experimenting, students noticed they could see ripples and splash, and said that "water dampens the sound."//
