A Rough Electrical Analysis of Clark Griswold's Christmas Lights, Part 3: Toasty Warm
Merry Christmas! I hope the holidays have brought you what you wanted, and that you have to deal with as few unpleasant relatives and explosive trees as possible.
We’ve discovered that there’s enough current flowing through the wires to get them to…

A Rough Electrical Analysis of Clark Griswold's Christmas Lights, Part 2: MOAR POWAA!
Last week we discovered just how much current Clark’s lights would draw; a massive 1040 A of current on a circuit only meant to carry 15 A.
When you get current that high, even the tiny resistance of wires starts to matter. Wires that normally conduct…

A Rough Electrical Analysis of Clark Griswold's Christmas Lights, Part 1: Keeping Current
Like many people, I have fond memories of National Lampoon’s Christmas Vacation. It’s a classic with my family, one we make a point to watch every year.
As a science geek, and with an electrical engineer father, seeing Clark’s rediculous lighting plan,…

Link: How a Radical New Teaching Method Could Unleash a Generation of Geniuses
I read this interesting Wired article on a teacher in Mexico who had some really great success using a version of Sugara Mitra’s “minimally invasive education”. It’s started me looking into it for my classes, and how that might work. (more…)

Frustrations with SparkVue
I’ve been trying to use Pasco’s SparkVue Mac application for data logging experiments in class. It’s supposed to be a simpler data logger than Data Studio or the more recent Capstone, but I’m finding it to be really frustrating.

Graph walking
One of the first struggles you might face when teaching Physics is helping students really understand how motion graphs show how something moves. If you have Pasco probeware, you’re in luck.
(Full disclosure: I learned this from Ian Fogarty, a great…

Turnitin PD Presentation
In past years, I’ve been using Turnitin for many of my internal assessment. Apparently, admin noticed, and I was asked to do a presentation on using Turnitin! Read on if you’d like to see video of the presentation. (more…)

Lego League and "Agile Development"
It’s not very often that you get a chance to show students how things work in real jobs. A lot of what we teach is theoretical, codified, crystallized knowledge, when what we want them to learn is how to work effectively with new, messy problems as…
