Day 1  WAVES

Today we gnats possible new world calendars, collected Great America $, had 3 handout, and covered wave vocab.
Note the powerpoint below that was used:

Day 2 Slinnnnky Lab, interference

Today we collected Great America $ and had students raise their hands if they are planning on going.  $ due this week (or at least $30 of it).  My classes have 67 students claim they are going.  You must know about this website as you are here smile2340.weebly.com.  Showed the Chap. 11 eactivity constructive destructive from textbook site.  Did half of each interference worksheet with class and students must finish the other half and turn in by Friday of this week.  Did lab that you must make up if you missed.  Lab sheet and materials in back of classroom.  Bring someone who has done it to work with when you come.

Day 3 Standing Waves, Wave Machine

Today we ran the powerpoint below which reviewed interference yesterday and taught what a standing wave is and provided me with the steps to take to demonstrate the expensive wave machine on the teacher's desk. Please go to the powerpoint below.  Remember textbooks are due this week and so is great america money.

Day 4 Hot Sounds, Microwave American Cheese to calc. vel. of light

We collect Great America $ and waited for students to go to locker to get textbooks.  We went in resoure area in back room with microwave under the vent hood and microwaved a CD for 7 sec. and watch the 4th of July fireworks.  This gives off toxic fumes is why under the hood.  Then microwaved american cheese for 10 seconds and measured the half wavelength between cooked sections to determine speed of light.  Then went back to classroom and watched flames in standing wave patterns and dancing to music.

Day 5  Resonance

Today we watched the Tacohma Narrows Bridge and Ms. Congeniality.  We also did four hands on:  harmonics in a vibrating motor on a string, resonance in a wine glass of water, wave interference with two speakers and walking parallel to the speakers at different distances, and twirling a string of beads to different harmonics.  Follow the powerpoint below.

Day 6 Speed of Sound Lab

Day 7 Sound (Day 1 of 2)

Only 1/3 of each class showed up so we just did most of the hands on activities for sound for understanding   We watched three short videos (a Bottle Band, Musical Rocks in SE Penn., and Crockadile Dundee II)  Then we did four demonstrations, namely:  Twirled wood paint stickes on a string, an index card glued to a tongue depressor with a cork on either side and a rubber band around the cork with a kite string attached so it could be swung, also holding a metal hanger upside down by two strings placed near each ear as you bang the hanger into an object, students in groups of five held empty carpet tubes over a bunsen burner and played several songs.  Note power point below.

Day 8 Sound (Day 2 of 2)

Today we went over the volcabulary of sound by use of a powerpoint and a sound handout.  Many students in each class brought in their musical instruments and played them for us as we went over the Physics behind each musical instrument.  We had students bring in Violins, Violas, Mandilins, different size Saxophones, Clarinents, and Mr. Radke brought in his banjo each period.




Day 9 Polarization

Today we played the coolest music instrument ever iand nvented called a Theremin.  It is the only instrument you play without touching it.  One hand held about a horizontal ring controls the volume and the other hand held near a vertical antenna controls the frequency.  Secondly, we moved the front two rows to the back of the classroom and I swung a noise maker over my head as I explained the Doppler Effect.  Lastly, I demonstrated polarized light (seperates light into only one plane) with four coat hangers zig-zagged into a transver wire wave and trying to pass through parallel slits in a piece of cardboard.  I also demonstrated why a protractor breaks at the same angle by showing the interference stress (rainbow colors) patterns in the plastic by placing the plastic between two polarized filters.  The last 20 minutes students did the lab.  Note the powerpoint below and Polarized lab activity get the lab made up ASAP.

Day 10 LASERS
Today we got out our April calendars and I explained that since I'll be at the 28th National Space Symposium next Mon, Tues, and Wed that we'd have to rearrange our calendar.  Next Mon. & Tues. will be review and next week Wed. the test.  This week Wed., Thurs., and Friday we'll start the next unit work recorded on next Mon, Tues, and Wed.  Next we played songs with the palm pipes followed by a short video on lasers.  We explained LASER stands for Light Amplification by Stimulated Emisson of Radiation, at least ten applications, and how lasers work.  Lastly we did a kinesthetic activity where the students all became electrons excited, followed by photons that went through stimulated emisson and became coherent, monochromatic light.

Day 11 Holograms
Today we had the 2nd Hologram of the ballerina set up in back so you could watch her spin as you walked by her.  Also, we had the coolest laser demo set up to send a radio station (oldies station) into a modulated laser to a solar collector hooked up to an amplifier so we could listen to the radio on the opposite side of the classroom unless someone blocked the laser signal.  We watched a 3.33 min video on how they make holograms and then gathered around the teachers desk to be shown an actual hologram setup of a reflecting hologram ready to be developed.  Next we did the Wave Study Sheet that you can find below period by period from the smartboard.

Day 12 Go to Unit 10 Light
Our monthly calendar needed to be rearranged a bit so today we started chapter 10 Reflection.  However, go to the following Power Point presentation to get the lights off learning review of Chapter 9 Waves.  You will review more next Mon., and Tues. then take the test next Wed.  Next Thursday we'll be back on tract with the calendar.
