Albert Fong 11-4 Waves, Group Work, Properties, Short Period , , ,

Before Class Preparation:

  • Video: How to measure the speed of waves
  • BYOD laptop or Chromebook from library
  • Does changing the frequency affect the speed of a wave?
    • Identify the independent/dependent/control variables

In Class Activity:

  • Investigate the relationship between the wavelength, frequency, and speed of a wave, and solve related problems

After Class Work:

Class Setup

Albert Fong Introduction

Before Class Preparation:

  • Basic knowledge needed for class. They are usually short videos or exercises to get you ready for the class.
  • There are handouts to be read over (and printed if possible) to get you ready for activities/labs in class.

In Class Activity:

  • Your teacher will give instruction for the day’s activity, which will usually be group-based.

After Class Work:

  • Google classroom will be used to organize assignments.
  • There will be some video lessons here to reinforce the learning.
  • CK12 adaptive practice that are assigned to check your understanding of the material covered (aka homework practice).
