Jeopardy Review - Waves and Sound
 * Wed 5/11**

// __Make-up:__ Read section 26.9 and answer 3 questions // Reviewing types of instruments - Blue man group and PVC instrument // (OAS - veggie instruments Natural Born Thrillers #17 //// ) // Interference is what waves do when they meet, for sound too! Reversing the wiring on one stereo speaker makes some of the sound disappear Two speakers playing the same note creates loud and quiet spots around the room = constructive and destructive interference
 * Tue 5/10**

// __Make-up:__ Use the internet to find out the difference between pitch, intensity, and timbre for sound. Write down your sources and answers // Used different musical instruments to make different sounds Three categories for sound changes: Pitch, intensity, and timbre Three categories for instruments: Strings, air columns, and percussion Blue Man Group - Drumbone

//__Make-up:__ Answer any 5 questions from the viewing guide// Video - Cosmos: Hiding in the Light
 * Fri 5/6**


 * Thu 5/5 - NO SCHOOL**

// __Make-up:__ Use Youtube or Vimeo to find and watch a video demonstrating each of wave resonance, standing waves, and wave interference. Give the title of the video and who it was submitted by. // - Review wave concepts using Youtube videos
 * Wed 5/4**

// __Make-up:__ Read section 26.8 and answer 3 questions // Resonance is when energy is added at an object's NATURAL frequency causing BIG vibrations Looked at examples: Two tuning forks, kid on a swing, suspension bridge, car on air track Then we thought of our own examples.
 * Tue 5/3**

Make-up: Mythbusters: Singer Breaking Glass
 * Mon 5/2**

// __Make-up:__ Read sections 26.6-7 and answer the 3 questions // Why are different sounds different? Sorting pennies by sound Tuning forks are labeled with their natural frequency We can force something, like an acoustic guitar body, to vibrate at other frequencies
 * Fri 4/29**

// __Make-up:__ Get "waves in a sink" packet from Leslie and complete it // Looked at an old-fashioned ripple tank Review of frequency and amplitude using the Phet Waves in an Electric Sink simulator
 * Thu 4/28**

// __Make-up:__ See Leslie to do a Vee Chart experiment // Vee Chart Project - Investigated a question about waves and sound:
 * Fri 4/22 - Wed 4/27 (Mythbusters Brown Note last day)**
 * How does the mass at the ends of the straws affect the speed of a wave machine?
 * How does the tension hanging from the wave machine affect the wave speed?
 * How does the length of the crinkle tube affect the frequency of the sound produced?

// __Make-up:__ Read section 25.9 and answer 3 questions // Doppler effect - frequency changes when source or observer is moving Watched clips and listened White board questions about simulators Spinning a tuner on a string in class Can we explain it?
 * Thu 4/21**

// __Make-up:__ Read section 25.8 and answer 3 questions // Review of interference - waves running into each other Standing waves: interference makes a wave appear to be standing still Ruben's tube: A visual representation of sound waves Making and measuring standing waves
 * Wed 4/20**

// __Make-up:__ Use the internet to find out about the Asian Tsunami on 12/26/2004 and write 3 paragraphs on what happened and how it affected people // https://www.youtube.com/watch?v=Eu512L5kQfg Video on devastating waves caused by earthquakes Dialectic Journal: What happened in the video? What was your response?
 * Tue 4/19**

// __Make-up:__ Answer 3 questions on section 25.7 in file // What do waves do when they meet? PEO with simulator Interference - the result of waves adding when they meet (+&-) Moire patterns are visual interference patterns of light and dark lines Practice drawing how pulses would add / cancel when they meet.
 * Mon 4/18**

// __Make-up:__ Get packet from Leslie and use a computer that can run java to complete it // Last terms for our sheet: wavespeed and period Practice measuring wavespeed in a simulator
 * Fri 4/15**

// __Make-up:__ Read section 25.2 and answer 3 questions about amplitude and wavelength // Frequency and period review OAS: People packed into a wave pool Defining amplitude and wavelength Measuring amplitude, wavelength and pulse time with a slinky and on the smartboard
