PHYSICS: How much fun!! How’d you like playing with color? So now, why is an apple red? So….here’s the lecture on color – colors of light, and colors of pigment.

PHYSICS: So why do instruments that are playing the same note sound so different? Here’s a discussion of harmonics.

PHYSICS: Here’s our 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? Let’s talk about that next time!

PHYSICS: So you can see sound?! Here’s the lecture for today – sound waves, echolocation, speed of sound, Doppler effect …. 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, the interference of waves and standing waves! Can you think of some applications of constructive and destructive interference?

PHYSICS: Here’s our first look/review of waves basics. Do you remember anything from your earlier 8th grade physical science days?

PHYSICS: So what do you reckon is the spring constant of a trampoline spring? Here’s our discussion from today on the simple harmonic motion of springs and pendulums.

PHYSICS: Great job with the Bernoulli problems today. Are you getting better at thinking through them? Here’s a look at some of them from last year. My best hint – #1 Determine if it’s a continuity equation or big Bernoulli equation problem, and #2 remember the concepts behind the formulas you want to use!!

PHYSICS: Good to be back together talking Bernoulli! Great start on setting up the Bernoulli problems today. My best hint – Remember the concepts behind the formulas you want to use!!
