(IWB - Day 156 Wave Interactions)
Today I previewed tomorrow's altered schedule due to the walking field trip to Digiplex. We discussed section 9-3 notes on wave interactions. I used a tennis ball to demonstrate reflection, and a giant slinky to demonstrate interference. I also used an electronic standing wave generator to show standing waves. We completed worksheet 9-9 together, and students had the final 10 minutes of class to complete and hand in their slinky lab report and rubric.
No homework was assigned, and the Chapter 9 test will be on Monday.
