PHYSICS: Can you believe it?!? This is your LAST web post comment!! This is where you put it and here are the three things I want you to talk about:

1) How did physics grow you? What did you learn about yourself?
2) What advice do you have for future physics students?
3) What could we have done different this year that would have helped you learn physics better?

Can’t wait to hear from you!! 🙂

PHYSICS: No sound on the recording of the test overview from today, BUT I did find an old overview of the sound chapter – with a short look at the speed of sound lab at the end. God bless you as you study! You’ve got this!!

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s our discussion of harmonics. (Plus another lesson on beats at the end.)

PHYSICS: Here’s our look at some of the conceptual homework from last night and then another look at some applications of resonance. And to finish things off – getting down and dirty with Beats! Well, not really, but how fun are beats!?!

PHYSICS: All kinds of ways to make music! And great discussion of intensity and resonance! Were you okay with the problems?

Couple of items to apply for further contemplation – so how does the whole hearing thing work? I mean, I know the little bones in your ear move, but why? Is resonance involved? Great item for application/discussion!

PHYSICS: So you can see sound?! Here’s the lecture from today – some wave stuff, echolocation, speed of sound, …. Too much fun!!

Also, here’s the link to the video we watched today on shock waves, supersonic flight and sonic booms: Supersonic Flight & Sonic Booms

PHYSICS: Cool thing, standing waves! Can you think of some applications of constructive and destructive interference?

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) 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!

PHYSICS – Here’s our very short look at simple harmonic motion and pendulums. Then back to figuring out bungee jumping eggs. Did your egg make it?
