Today we got through the 19th Century history of Electromagnetism and encountered Ohm’s Law Faraday, and Maxwell… Here’s the Make Magazine video on Ohm’s Law that we watched in class… it’s a fantastic video covering how voltage, current and resistance are related (watch again!)… Finally, we’ll pick up with Tesla and Einstein tomorrow. Here’s a [...]

I’ve finished grading listening to your awesome song remixes from our Sound Unit. I have to say, I’m blown away by some of these… amazing work! Here are a few fun highlights: – Eleanor has MG play Diary old-school manual style. – Jesseca brutalizes Meet The Elements and turns it into a dark goth-punk anthem [...]

This week we’ll be completing our studies of sound waves. To wrap up, we’ll be working on a fun activity… 1) Think of your favorite song. 2) Find 5 points of frequencies from the song. 3) Find 5 wavelengths from your song. 4) Remix a segment of your song to change 5 points of frequencies [...]

Today we continued our studies of waves by continuing to dig deeper into the world of mechanical waves… most notably sound. To really understand sound, we have to understand the human experience of interacting with sound. So, we start with the ear. Tomorrow we’ll finish our labeling and do some fun and quick labs: Sound [...]

Today we continued our studies of waves by looking at the fascinating property of resonance. Here are a few examples: Tacoma Bride Fail Can a singer break a glass with just their voice? Tomorrow we’ll continue our studies of wave energy and move towards the subject of sound. Should be fun!

Today, we continued our studies of waves and discussed the main parts of a wave. Here are our main points from today… The Four Properties of a Wave Frequency = Hz Amplitude = amount of energy/displacement in a wave Wavelength = distance from one point to the corresponding point on a wave. Speed = wavelength [...]

Here is a link to the presentation I had for you in class today: http://public.iwork.com/document/?a=p103636129&d=Light.key Make sure to review slides 18 and 19!

Huge news… Scientists supersize quantum mechanics : Nature News: “A team of scientists has succeeded in putting an object large enough to be visible to the naked eye into a mixed quantum state of moving and not moving. Andrew Cleland at the University of California, Santa Barbara, and his team cooled a tiny metal paddle [...]

Tomorrow we’ll be wrapping up on our brief tour of the history of electromagnetism. Please make sure to review your notes in case I have a *SURPRISE* for you in class. In the meantime, go watch this lecture: Fantastic.
