(IWB - Day 154 Wave Speed)
Today students presented their 31st week of science news articles. We discussed section 9-2 notes on speed, frequency, amplitude and wavelength of waves. Students were assigned worksheets 9-2, 9-3, 9-4 and 9-5 to be completed within their groups before the end of the period.
No homework was assigned, and the Chapter 9 test will be on Monday, May 6th.
