Diego Vargas Today in Mr. Manning Pyhsics class we started class having to turn in the Hersey park parent slips if we had it. Also we were reminded about the quiz on thursday on waves and we were reminded about the roller coaster designs due on Friday. Then after all those reminders we had a daily questions on energy transfers and one of the questions were "Which direction will this point move on a longitudinal wave?

Then after we reviewed the daily question we finish reviewing all the waves and all 3 types of waves. Mr. Manning introduced a new lab called "Mechanical Wave Characteristics Lab " groups of 3 and every group had to grab a slinky and every group had a different problem to do. For example, some group had to tell weather the length will do a difference to the speed of the pulse or another example was if the amplitude of the wave pulse change. All groups were to continue the Lab on the next day.
