There was a link to this lesson in the most recent TED Ed newsletter, and I immediately jumped at the challenge. I’m a bit competitive sometimes;)
I will say that I did solve it before the solution was revealed on the video, but it probably would have taken me as long as anyone else if I wasn’t able to view the clips of people guessing incorrectly.
This is an excellent lesson on how we often make assumptions, and then look only for the evidence that appears to support them. Lots of classroom discussion could definitely branch off from this one short video.
You can find more Veritasium videos here, although I always recommend that you watch videos prior to showing them to your students to determine if they are appropriate for your audience.
Note: There is an “inappropriate” word said extremely quickly at about 2 minutes in.
OMG, this is brilliant! I will have to use this video in class! Like you, I think I figured out the rule a little bit ahead of the video but not by too much. Definitely a great way to view things…and how to approach problem solving…
Isn’t it a great piece? It’s so simple, but loaded with discussion potential!
