Physics 4-2-24 Properties of Waves

PHYSICS: Here’s our lesson on the properties of waves. 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 (v = λf).

Easy peasy – and don’t forget the applications!

BONUS: Here’s a link to a NASA Launchpad video on wave motion – NASA Launchpad: Wave Motion. Since we didn’t get to play with slinkies today in person, this will be a good replacement!

Hon Chemistry 4-2-24 Electron Configuration Notation

HON CHEMISTRY: just when you were getting the hang of drawing arrows, I go and change it! But don’t you think writing electron configuration notation is a whole lot shorter than doing orbital notation? Don’t get me wrong, knowing how to do orbital is great for seeing how the electrons are paired, but this way is way shorter! And speaking of shorter – let’s crank it up with noble gas notation tomorrow.

HW UPDATE: Only do the regular electron configuration notation tonight. You don’t have to do the questions about noble gas notation.

Be sure and practice with the homework tonight, and don’t forget to use the Aufbau “chart”!!!!
