We discussed section 9-3 notes on wave interactions. Students worked on worksheet 9-9 in their groups for eight minutes before we went over the answers together. They had the last 10 minutes of class to finish their slinky lab before handing it in. They also could work on completing worksheets 9-6, 9-10 and 9-11.
No homework was assigned, and the chapter 9 test will be on Friday, May 13th.
