How the Sun Sees You
I found this video to be totally captivating. The message is an important one. But the soundtrack is also nice. And then… how did they record this? See for yourself.
I love the "Oh My God!" moments. The appearance of the sunscreen didn't surprise me. We try to incorporate the opacity of sunscreen in our ExploratoRio Purple Haze exhibit. What I came away really wanting to know was… how can I set up a similar rig to capture live video in UV? Cameras with glass optics and glass filters and glass over their sensors are well protected against ultraviolet light.
The Exploratorium's Paul Doherty shared this informative Photonics article.
Ultraviolet Reflectance Imaging
The article mentions fused silica optics. Paul recalled grinding sodium chloride lenses for use in UV imaging. Fused silica and salt lenses? My ignorance is so vast, sometimes it hurts.
Here's a video tutorial on getting a DSLR modified and configured to shoot in the UV range. It's, well, a nontrivial affair.

Planning the year: NGSS, AP1, and AP2 - Part 1: The broad strokes
My assignment for the 2014-15 academic year includes Physics, AP Physics 1, and AP Physics 2. The Physics course should be aligned to Next Generation Science Standards. Our students are years from facing NGSS assessments; right now school officials of nearly every stripe are focused on Common Core State Standards nearly to the exclusion of any other academic concern.
Last year marked my first attempt to let go of the past decade+ focus on California's now-abandoned academic content standards in physics.
Advanced Placement Physics 1 and Advanced Placement Physics 2 debut this year, and Rio has enrollments in both. Now that AP Physics B is dead and gone, The College Board is laying the AP1 and AP2 cards on the table. My friend, Chicagoland physics teacher extraordinaire, Martha Lietz, pointed me to her AP Physics resource page. And I have been poking around in the links!
This post will give a general direction of how I plan to implement the three courses at my school.
Physics remains a first-year course with an Algebra 1 prerequisite. It needs to fulfill the needs of NGSS as well as provide a suitable foundation for students who might elect to move onto AP Physics 2. It is not feasible to allow Rio's pipeline to AP2 be restricted exclusively to AP1 "alumni".
AP Physics 1 is a first-year course for highly-motivated students who have passed Algebra 2. It must cover the AP Physics 1 syllabus provided by the College Board. But it must also cover the expectations of NGSS.
AP Physics 2 is a second-year course for highly-motivated students who have passed Algebra 2 and a first-year physics course (Physics or AP Physics 1). It must cover the AP Physics 2 syllabus provided by The College Board.
In any case, here's my plan so far. Click to embiggen. Subject to change!
And yes, I'm willing to try the current fashion of energy before momentum. Wide ties/narrow ties. It seems that among the cognizanti, teaching momentum before energy is on par with wearing a wristwatch or typing two spaces after a period as far as age indicators go. I know there are strongly-held beliefs, arguments, and preferences here. Sometimes I think we get too exercised about such things.

In good company
Generally speaking, previous AAPT award winners were inducted as the Inaugural Cohort. I was a recipient of their Distinguished Service Citation in 2008. And that's how I came to be included on a list of physics-teaching heavyweights. It's true, I have an ego the size of Montana, but I'm also grounded enough to know I'm dwarfed by the giants on this list.
