Waves Day 1

We've worked in the new book once before.  Today I'm going to introduce you to the old book.  I don't have access to this book online.  We are going to complete a fill- in- the- blank today that will go in your notebook as number 1.  The answers will presented to you at the end of class.  The notes can be downloaded here and the answers here.
The start up for today is "What are three examples of waves?"
