Due to the nice weather this week and the rain forecast for next week we moved up our speed of sound lab--we went outside with large cymbals and timers and determined how fast sound travels. The lab for this activity is on page 130 in our textbook.
We also experimented with the doppler effect using our buzzing frisbee. We found that as the annoying sound went away from us it dropped in pitch--when it was thrown toward us it rose in pitch. We also determined that Mr. J can still throw a frisbee...
Back in the classroom we looked at our experimental data and discussed the areas where error could have entered our data.
Reminder--ten points of homework are due on Monday/Tuesday October 6th and 7th
