Day 113

(IWB - Day 113 IMA of Simple Machines)

Today we listened to summaries of Week #23 science news articles.  Students were given back their chapter 7 vocab quiz from last week and we went over the answers to each of the 25 questions.  We discussed section 7-7 notes on ideal mechanical advantage of a simple machine, and used that to complete problems 2, 3 & 4 on worksheet 15-8.  I then reminded students how to find work output and work input before they worked on page 15-10 until the end of class.

No homework was assigned, and the Chapter 7 test will be on Thursday, February 28th.
