Still Wavin'

Physical Science completed their introduction to waves today with a general review and discussion of their standing wave lab. Tomorrow - exam. Have your worksheets, practice test and daily object answers (for wave chapter, only) ready to hand in before the test begins. On Friday, we begin exploring sound and light in detail and sound will lead the way. Friday's lab will allow students to measure the speed of sound in air and, if I remember to buy Alka Seltzer, carbon dioxide.

Physics reviewed their pendulum lab and began their discussion of wave properties. Tomorrow's lab will further investigate SHM by analyzing a mass-spring system. SHM can produce waves that have the properties of the vibrating source. The vocabulary and concepts that we develop with SHM will carry over when we begin to dig further into wave phenomena.

Honors Physics began their pendulum lab today. Data was collected and data analysis began. We'll finish up with the data analysis tomorrow and wrap up with a general discussion of this lab and the mass-spring lab. Keep in mind the wave ideas we've been been developing and see how they relate to objects oscillating with simple harmonic motion.
