If you missed today:

1.  We did the MAD LAB which is a quickie lab in groups 2 or 3.  This is the last lab for the Seniors!

Having your Lens Ray Diagram sheet out for this lab helps as you go through cases 1 and 3 to get the focal length and then do cases 2 & 4 after marking your meter stick that has the object and image card on it and the lens in between.  Note video below if you are confused.

2.  The Refraction Lab was due today also so make sure you turn in your part of it as your group probably handed in their parts already.
