PROJECT UPDATE 1
MY IDEA
My idea is to make a youtube page where I post a video on each Wave standard, which I explained using processes in the kitchen. It is essentially a cooking show where I incorporate physics to explain waves. This is a good way to represent wave concepts because it takes a creative approach to explain a topic using the knowledge that many people already have on cooking. Almost everyone cooks, yet not everyone knows the mechanics behind it so this is a great way to teach both about physics and about cooking. I will create this project by periodically posting videos, maybe once a week, where I go through a specific standard utilizing one aspect of cooking (microwave, chopping, a certain food).

Kitchen appliances and some ingredients
A video editing software (iMovie)
Waves Standards
What is a wave? How are waves produced? Compare and contrast the 2 types of waves.
I will show how waves are produced by explaining the mechanics behind a microwave. I will explain the disturbance which causes these electromagnetic waves and that it carries energy. I will illustrate the 2 types of waves by explaining that the electromagnetic waves inside the microwave are transverse waves while the beeping sound when the timer is done is a longitudinal wave.
What is the relationship between f, T, λ, and v of a wave? (conceptual and mathematical)
I am making a microwave cake, so I will use it to show what frequency, wavelength, and period are by cutting them at different speeds and distances apart. I will explain velocity using these ideas and the equation for velocity. Then I will take the actual data behind the microwave to make a mathematical equation which I will then solve.
Evidence of standards 1 and 2
Made my youtube account where I will be posting videos
I finished recording all the videos I will be combining into one for episode 1 of the show.
Here is my intro video to the episode:

I am now putting together the videos on iMovie. I am editing, doing voiceovers, and making sure it looks and sounds as professional as possible. Once I am done with this, I will post the first episode to my youtube channel. This should be up sometime in the near future.
PROJECT UPDATE 2
Reflection
In my project thus far, I have finished all the filming and putting together the clips to make my first episode of standards 1 and 2. I am in the process of doing the finishing touches of editing for this video. After receiving feedback and running into trouble trying to incorporate standards 3-5 in a "cooking" show, I have expanded my idea. My idea is now a house tour, where I will be using things in different spaces in my house to explain/demonstrate wave concepts. Sticking with just the kitchen was far too limiting, so this opens up way more options for me to explain these concepts.
Waves Standards 3,4, & 5
What are the necessary conditions for a wave to demonstrate interference? What characteristics of the wave change?
This part of the tour will be of my room. I will first demonstrate interference by using my speakers and creating interference between them. I will explain what they are hearing in terms of waves. Then I will explain standing waves by creating them on my guitar.
What are the necessary conditions for a wave to demonstrate refraction? What characteristics of the wave change?
I am going to do an experiment similar to the penny trick we did in class. I will be "touring" my bathroom and I will place an object in the sink. After barely going out of view, I will fill up the sink until the object can be seen again. Then I will explain the refraction, and use Snell's Law for Light to set up an equation to find the angle of refraction and angle of incidence using water and air's index.
What are the necessary conditions for a wave to demonstrate diffraction? What characteristics of the wave change?
I will be "touring" the laundry room for this standard. I will be using the sink and turning the pressure all the way up. I will then create a bigger "barrier" with my fingers and demonstrate how it creates smaller diffraction than a smaller barrier which spreads out the water more. Essentially, I will be acting as if the running water is the waves passing between my two fingers acting as barriers, to demonstrate the principles of diffraction
Evidence of Standards

Automatic 2.MP4
Video of me messing around with shutter speed to be able to demonstrate standing waves. If you look, you can see the waves wiggle on the strings because of the camera settings. (not actually gonna use it in the video, will re-film it to show it better. Just messing around here). You can see the standing wave (sort of) towards the last 5 seconds of the video.
