In the Computational Thinking video
(https://www.youtube.com/watch?v=BAxW5vzREr8), at 1:14, you can see the
Five Big Ideas in AI poster in a classroom.  For those who don't know,
April was the one who originally suggested we create this poster.  She's
speaking at 2:12 and 3:52.

In the shorter "sizzle" video
(https://www.youtube.com/watch?v=l-D7c9tUbb4) , April is at 00:51, and
the poster can be seen at 1:35.
