Students turned in their 24th news article. We discussed section 7-7 notes on Ideal Mechanical Advantage of simple machines. We completed worksheet 15-18 on mechanical advantage of simple machines in about a minute. Students then completed problems #2, 3 and 4 on worksheet 15-8. Finally, students were assigned worksheet 15-10 on mechanical efficiency.
No homework was assigned, and the chapter 7 test has been moved up to Thursday, March 10th.
