Colors of light

Monday the Limits of Light posted by Go Wild was used to introduce the connection between colors and wavelengths along with the general notion of the electromagnetic spectrum.

Wednesday cold opened with a video titled Indigo by Indonesian singer-songwriter Nicole "Niki" Zefanya 

No one paid any attention to the cold open. I asked the class what the video was about, but no one had watched the video. One student did eventually hit on "blue" as the theme.

I then pivoted to the spectrum boxes. The students saw six colors. No one had any issue with that determination. I used this to suggest that in order to understand the science of a particular period one has to understand the cultural understandings of that age. No one caught the six reference. 

Once I made the explicit connection I moved on to seven days in a week, seven musical notes in an octave, seven visible moving objects in the Newtonian night sky, seven Platonic solids, and the sevens in Newton's faith.

Laboratory eleven opened with a playlist. The playlist is well tuned to the laboratory and the theme of the laboratory. Themes include that yellow is an invention of the mind, not the eye. That red, green, and blue are the primary colors of light because those are the colors, roughly speaking, that our eyes register. 

Forgotten this term: the Blackview BV 4900 which allows me to photograph the screen and has larger pixels than the Pixel Pro 7.

Then I photographed a donut and put that image under the microscope. The microscope had been placed in the rolling cabinet the day before.

I walked down to get a photo of the yellow culvert but ultimately did not use that in class.

An oahr remnant was serendipitously discovered on that walkabout. I would use the donut in class. 

Valerina and Aimee work on their phones.

Valerina gets creative with her circles.

In the 8:00 section I began to play around in Desmos, which led some students to get creative as well.

At 11:00 I used this image of Sphagneticola trilobata, brining the flower into the laboratory. The donuts almost worked better. The brown donuts lit up only red and green. This brighter yellow lights up some of the blue phosphors. In the afternoon I built a Desmos off of Valerina's design. As a result a student built a multicolored set of circles that formed rings.
