Here's the last lesson of the year!
Lesson 1 (U5 Day 11 & 12) Lenz's Law, Generators, and Transformers: 13.1 - 13.5
- Watch Crash Course on "Induction" for review of last week and an introduction to this week's lesson: www.youtube.com/watch?v=pQp6bmJPU_0&list=PL8dPuuaLjXtN0ge7yDk_UA0ldZJdhwkoV&index=35. Too many formulas for our needs, but the ideas are all good!
- Skim Sections 13.1 - 13.5 in the text.
- Note: u5_lesson_7.docx
- Watch Crash Course on "How Power Gets to You": www.youtube.com/watch?v=9kgzA0Vd8S8&list=PL8dPuuaLjXtN0ge7yDk_UA0ldZJdhwkoV&t=0s. The beginning of the video has a slightly concerning family sceene and there's way too much detail in terms of formulas, but the general information will reinforce note.
- THAT'S IT!!! YOU FINISHED THE COURSE!
Remember to complete the culminating: sph3u_culminating_task_covid.docx and submit it by Monday, June 15th.
Our school board informed teachers this morning that all YouTube videos accessed by school computers and/or accounts must now be approved by teachers in advance. This notice appears to have been effective immediately.
Given that we are now into culminating and report card season, along with the complete lack of notice, I won't have time to go back through all of our lessons and grant access to all of the YouTube video links. Next week I'll work on approving the videos posted for the "Week of June 1st" and obviously any videos for the last week of lessons will be approved as I post them. Older videos can still be viewed through non-board issued devices using non-board accounts - hopefully you can access a personal device if you need to catch-up and/or review course material.

This week we'll be covering the last concept in the sound unit and then proceeding with a review of Grade 9 electricity in preparation for our last unit on electromagnetism.
Lesson 1 (U4 Day 8) Resonance: 10.4 & 10.5
- Read over Sections 10.4 & 10.5
- Resonance occurs when an object absorbs vibrational energy from the environment. Every object has an inherent natural frequency of vibration based on its materials and construction. If the environmental vibration is at this natural frequency (or a multiple of it), objects can start to vibrate as a result of the absorbed energy.
1. A child on a swing:
A swing is essentially a pendulum. It will have a natural frequency of vibration based on its length - this won't change no matter how hard or fast you push the child. If you push the child every time he/she returns to you, the swing will absorb energy and its amplitude will increase as a result.
2. A singer breaks a glass:
A glass has a natural frequency of vibration. If the singer matches this frequency (or a multiple of it), the glass will start to vibrate (glass is somewhat flexible). If enough energy is absorbed the amplitude of vibration will exceed the flexibility of the glass and it will shatter.
This is a cute video of a boy breaking a wine glass with his voice: www.youtube.com/watch?v=sH7XSX10QkM. Notice the use of the straw - it is there to indicate when he is nearing the natural frequency of vibration of the glass. As the glass starts to vibrate, the straw starts to move.
This video shows the actual vibration of the glass rim: www.youtube.com/watch?v=CdUoFIZSuX0.
3. Tacoma Narrows Bridge:
Video: www.youtube.com/watch?v=XggxeuFDaDU. In this video the wind pushes the bridge to a point where the restorative elastic force is greater than the force of the wind and causes the bridge to swing back. This set up an oscillating motion that happened to match the natural frequency of vibration of the bridge. Over the course of a few hours, the amplitude increase beyond the breaking point of the bridge and the structure collapsed. Yes, a dog died... It was scared and the people couldn't get it out of car.
So I once heard a rumour that the engineer's ring (given in a "secret" ceremony upon graduation) was made from the metal of the Tacoma Narrows bridge for Americans. I actually went and looked it up today - turns out the tradition of the iron ring was actually started in Canada in the 1920 and adopted by the Americans later. Read: blogs.scientificamerican.com/oscillator/ring-ritual-reminds-engineers-of-their-responsibility/.

Lesson 1 (U4 Day 3 Part 2) Standing Waves: 9.2
So last week you looked at what happens when waves pass over each other (Principle of Superposition) and what happens when waves reflect off of fixed or free ends. Those two concepts will be put together to explain standing waves.
- Its easiest to start with waves on strings. When you pluck a string (i.e. guitar, harp...), you create a wave that travels to the ends and reflects back (inverted because of the fixed ends). The waves then interfere with each other to form a stable interference pattern called a standing wave. The vibrations resulting from this produce a sound at a particular frequency.
- Watch the following explanation of "Standing and Stationary Waves on a String": www.youtube.com/watch?v=GsP5LqGtkwE
- Note: standing_waves_and_harmonics_online.docx
- When you pluck a string, the primary note you hear is the fundamental. The other harmonics are present too (each quieter than the previous) and they add "colour", "richness", "warmth" and an "organic" quality to the sound. If they are not present, the note would sound artificial - kind of like the early synthesizers used in 1980's music. See Text p. 455 Figure 4 to see what the resultant wave would look like when all of the harmonics are added together - its easier to visualize them separately.
- The fundamental note of a string depends on its length, linear density (i.e. guitar strings have different mass/length), and tension.
- Different notes can be produced by changing the length of the string that can vibrate - this is called "fretting". When you push on the string at a particular point, only the part below your finger can now vibrate to form the wave and this effectively changes the length. A shorter length = shorter wavelength = higher frequency = higher note.
- Strings with lower linear density ("light" strings) have higher speeds of sound (see previous note). Since speed = frequency x wavelength, "light" strings have higher frequencies and higher notes.
- Strings under higher tension have higher speeds of sound. This is how we control the tuning on most string instruments. A "nut" on the headstock (top) of a guitar can turn to tighten or loosen the string. Tightening the string causes a faster speed of sound and since speed = frequency x wavelength, higher frequencies and higher notes are then produced.
- Watch Professor Dave on "Standing Waves and Harmonics": www.youtube.com/watch?v=0Rfushlee0U
- Under normal circumstances we would be expanding this explanation to include standing waves in wind instruments but we won't be covering that this semester.
- The expectation here is that you will be able to do the following for waves on a string.
- Draw waves of different harmonics. Note that there are two naming conventions (musical and scientific)- you should know both.
- Given the length of a string and the harmonic type, figure out the frequency. See p. 425 Sample Problem 2.
- Be able to work the problem above in reverse: give the frequency and the harmonic, figure out the length.
Lesson 2 (U4 Day 4) Beats, Damping, and Doppler: 9.3 - 9.5
This section will be looking at three wave phenomena.
Beats:
- When two notes of similar frequency (so close you can't tell them apart by ear) are played at the same time, they interfere to produce patterns of loud and quiet sound.
- The difference between the frequencies (positive value of f1 - f2) is the number of "loud/quiet" cycles that are heard per second.
- If the frequencies are very different, the number of loud/quiet cycles becomes so numerous that our brain interprets is as one continuous sound. At this point, you would usually be able to tell the difference between the notes by ear.
- Go to www.explorelearning.com and open "Sound Beats and Sine Waves".
- Select all "Visual" options.
- Set Sound A to 442 Hz and listen to it on its own.
- Set Sound B to 440 Hz and listen to it on its own.
- Now play the notes together and observe the interference pattern with respect to what you're hearing.
- Experiment with different frequencies.
- Answer the questions at the bottom of the Gizmo - This can be your weekly check-in!!!
Natural process by which vibrational energy is dissipated into the environment . See Text p. 430 Figure 1.
- If dealing with sound, this is observed when a note that is played "fades".
- It can also be observed if you stop pushing a child on a swing - then eventually come to a stop.
- This is a good thing when dealing with things like airplane wing vibrations - without damping, plane vibrations could add up and cause the wings to "flap" right off the plane (slightly exaggerated - would cause damage).
- Watch Sheldon from Big Bang: www.youtube.com/watch?v=z0EaoilzgGE
- This effect is observed when the source of a sound and the observer are moving towards each other or apart.
- Go to www.explorelearning.com and open the ''Doppler Shift Gizmo".
- Play the "Sound Sample" to get an idea of what this would sound.
- Select "Display additional waves" and "Observed Frequency".
- Press "Play", watch for a few seconds and then pause. Notice that the waves in front of the car are closer together (more frequent = higher "note"). This occurs because the car is moving forward as it emits waves and partially catches up the the waves it just released. The opposite is true for waves behind the car - they are further apart and would be heard as a lower note.
- Increase the speed of the source to about 200 m/s (yes - this is ridiculous) and notice how the effect is more extreme.
- Set the speed of the source equal to the speed of sound and play. You should see that the waves in front get all "bunched" up because the plane is completely catching up to the waves it previously released. This is called a "sonic boom" - it occurs whenever an object's speed equals the local speed of sound. It is observed as a really loud sound because all of the waves in front add constructively to produce a large amplitude. Once a plane accelerates past the speed of sound, the sonic boom dissipates. This is why living near an airport (with planes are often passing through the sound barrier) can be very loud. Sonic booms are also observed in the "crack" of a whip (the tip of the whip goes faster then the speed of sound), and thunder (air particles are heated, expansion of air is faster then the speed of sound).
- Answer the questions at the bottom of the Gizmo - This can be your weekly check-in!!!
- Read Text p. 424-425 for the formula on how to calculate the "new" observed frequency in a Doppler shift. Pay particular attention to the example. Make sure that you note the convention that Vsource is negative if moving toward the observer and positive if moving away (I personally find this counter intuitive so be careful of this in your homework questions).

I still haven't hear from the following students (initials only): K.A., N.H., N.M., J.V.. If you're online please let me know that you're O.K. and can access our course material. Otherwise, keep working on your lab and research assignments.
For the next unit, I will be modifying our unit outline to reduce the number of expectations and the corresponding hours of work. Starting on Monday, I hope to have a new Unit 3 Outline posted - no new work will be posted until then. I'm also going to be cleaning up this website to try to make it easier to navigate. As a result, some things may disappear if they are no longer needed or may be put into folders. Please check back on Monday.

The new online Newton's Law Lab is posted below. You can open the Word file and answer questions directly in the document, then save and send as an email attachment. Alternately you can put answers in a new file (like a google doc you can share). You'll need access to exploreleaning.com to do the lab - let me know if you need your username or password. Graphs can be done in Sheets and shared, Excel and send as an attachment in email, or by hand with pictures taken and emailed. Let me know if you have any questions/need help.

If you've completed the friction questions then you're pretty much done for the content portion of Unit 2. The only things remaining would be the assessments. Obviously Q2b and the test can't be done at this moment but the lab and assignment can. For the research assignment, I'm going to ask you to continue working on it and submit it as a google slide. You won't need a rubric with it (it's online if you can't find yours) and I'll modify the communications portion. Instead of being based on the presentation, I mark for the following: images are reference directly below (just copy the url), font is large enough, minimal words per slide, visually appealing, references are included at the end.
For the lab, I'll be posting an online lab for you tomorrow.
Due dates are as follows (still following our original calendar):
Research Assignment due Thursday April 2.
Lab due Tuesday, April 7th.
