PHYSICS: Today’s lesson is three parts. First you’ll watch a short vodcast on the properties of waves and then a short NASA video on wave motion (link is below) since we won’t be able to place with slinkies today in person. To wrap it up and make sure you have the concepts nailed down, there are three activities from the The Physics Classroom that you’ll do.
1) Vodcast – view below
2) NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion.
3) Either your book HW for tonight or The Physics Classroom Activities – Concept Builders: Wave Basics, Wave Cases and Concept Checkers: Simple Wave Simulator (either mode is okay)
Do you remember anything from your earlier 8th grade physical science days? Problems are pretty simple for you, I think. Do you remember the main formula from chemistry? Speed = wavelength x frequency (c = λf). Easy peasy – and don’t forget the applications!
