Day 64: Binder Checks

Tuesday, 11 November 2014


Test day in two classes and pinhole camera darkroom day on a third. Above, in grading an excellently organized bonder. The sticky notes I’ve printed on are a huge timesaver.


Classwork from two different units in an excellent binder. Colored copy paper is a resource I’m so glad I have.

The kids in the darkroom are struggling with making their cameras light tight. Midst couldn’t fix the problems within the period while exposing 3-4 images. Pictures of cameras and photos coming soon.

Day 63: Battery, Bulb, Wire

Monday, 10 November 2014


Can you light a bulb using only one wire, one battery, and one bulb? (Probably apocryphal, but MIT engineers supposedly struggle with this question.) This is easily my top unit intro activity — I did it last year on Day 67. We’re starting our electric circuits unit this week.

I asked them to sketch what doesn’t work:


After we found all the different configurations to light the bulb, the kids wondered what would happen if they used more batteries:


When you ask the kids what it takes to make the bulb light, they tell me “a circuit”. I ask “why?” They say “so the electricity flow.” I ask “what’s electricity?” They’re stumped. I ask “what do you mean by circuit?” They say “a loop of connected wires or parts.” We’re already hinting at ideas like serial (batteries), positive and negative terminals, current, voltage, and even short circuits.

Day 62: Geocaching

Friday, 7 November 2014


The Discovery session I’m leading is themed around geocaching. Above, I placed a new cache and recorded the coordinates. (App is called c:geo)

In class, I spent some time outlining the last unit before unleashing students on self-directed study time. I’m super happy at the results because it helped students see the whole unit in context.

Day 60: Tarp Flip

Wednesday, November 5, 2014


I’m a part time Discovery faculty member, which means I occasionally help lead freshmen on their experiential outdoor, expedition, team building course. Here, a group of about 10 have just succeeded in flipping a tarp over while standing on it.

Day 59: Help Me Write a Test Question

Tuesday, November 4, 2014
Given this picture, what’s the best question I could write to accompany it? I’m favoring “What is the most likely liquid in the dish? (give a list of liquids with indices of refraction)”

My kids completed their refraction lab today and I snapped a few photos in case I want to use them on an upcoming test. I’m beginning to think I need to revisit “lab questions” on my tests.

Day 58: Conferences

Monday, 3 November 2014
Today was set aside for advisement conferences, no school for students. I met with the parents of the eight young women I advise. Exhausting but totally worth it to see the whole-picture view of these students.

I also spent time picking the brain of my neighbor next door. My grading load is crazy right now, so I asked how he manages it. He told me three things: 1) break bigger labs into several smaller chunks, 2) get kids to self-correct their labs in pen when you go over them just before turning the labs in, and 3) only grade some parts of the lab. He said he mixes what he grades up, sometimes grades what he deems important other times going kind of random on them. I’m totally behind him on breaking labs into chunks. Done. It never occurred to me that I could have kids do quiz-style corrections on labs. Genius! He grants nearly full credit for a corrected answer to a lab question. I can do that, starting pretty much immediately. As for grading a portion, I dunno. But for now, the first two help me out a bunch.

Man, I love having colleagues who teach what I do and know what’s up.
