[…] only one student remained and he was working on his project based on Dan Meyer’s tinted sunglasses video. It being Friday, an hour and a half after school ended, our brains were fried and we just could […]

I like this video project. I can see it fitting in as a great hook when we start looking at exponential functions and exponential decay.

Thanks

I love the new version, so my hand is raised super high! I am still wondering if there is any way that we can have these re-submissions chronicled rather than just nuking them from the server?

So that it resubmits it into the list, and we can see the development of the task. Like a portfolio of task creation. Too complicated? You’re probably right. I just love seeing the creative thought that goes behind these remixes.

I’m pretty sure my whole teaching career has been “revise-and-resubmit.” But that is the great thing about teaching: you can reinvent yourself every year, every day, every period. It is one of the reasons I love being a teacher. It sure isn’t the paycheck . . . but I am not complaining!

Off topic, but did Dan duck as he went out the door? Didn’t realize you were that tall!

You might be able to put the pieces on a scanner, and get a number for the color of the dirt, and the size of it. The scanner can usually be set to not automatically change contrast.
In the olden days of cameras, there used to be an accessory called a reflectance meter. You might find one in an old camera shop. You could set up a light system and then measure the reflectance.
Another suggestion, if you happen to know a medical person, is to use a finger oxygen sensor. You might have to put some sort of blocker in until you get a reading, but you could play around until the stains gave you a reading change. One wavelength, so more standardized.
There are companies that make colorimeters, but they probably won’t give you one.

Nice glasses, Elton….

This video reminds me of a project a student conducted in an AP Stats class of mine a few years ago. The student was interested in determining if Oxy Clean was better than Tide at removing stains, and cut apart clean t-shirts, smeared them with ketchup and chocolate sauce (blood was disallowed), and cleaned them. This resulted in about 50 swatches of cloth with various degree of stain-li-ness. The problem was that, while we understood that some shirts “looked” cleaner, how could we measure it?

The same idea applies here. A student may “know” that the result will be darker, but how to we measure darkness? It would be interesting to see what kids come up with for conducting such a measurement. How exactly do we measure “tint”? How do we know that something has 50%, 75%, 5% tint, etc?

Hand raised high over here!
I want to get a few more views of my Rock Paper Scissors – Act 1 and see if it’s worth a reshoot. I thought it was a slam dunk, but seems to have reached a stagger.
I’ll admit, I found the sunglasses version more appealing than the Target Tint. Appealing to perplexity that is. Plus, we get to see you sport those lovely oversized beauties. :P All in the name of learning!
