Why Do Airlines Sell Too Many Tickets?
In Why Do Airlines Sell Too Many Tickets? students can learn about the mathematics that airlines use to maximize the revenue that they can generate from each flight. That math includes calculating the probability that everyone who holds a ticket for a flight will actually show up for the flight. The way that probability is calculated is explained in the video. Finally, the lesson asks students to consider the ethics of overbooking flights. Watch the video below or go here to see the entire lesson.

The idea is to take one picture every day to document the changes in the foliage as we progress through autumn from the first few orange leaves to full-blown autumn foliage colors to the drab brown we see after in the winter.
Here's how your students could create their own autumn foliage time-lapse videos.
1. Take one picture per day of the same view or of one singular tree.
Using a cell phone is probably the best tool for this because students rarely go anywhere without one.
2. Upload the pictures to a Google Drive folder.
It only takes one tap to move photos from a phone phone to a Google Drive folder labeled "Fall foliage." If This Then That has a recipe for doing this automatically from Android phones and from iPhones.
3. After four to six weeks, upload photos to JellyCam or Stop Motion Animator and create your timelapse.
JellyCam is a free video editing program for Windows and Mac users. You can easily adjust the duration of each frame and easily add a soundtrack to your video. Click here for a video about using JellyCam. Stop Motion Animator is a free tool for creating stop motion movies on Chromebooks.
Today I had the pleasure of giving four short presentations at the Texas ESC-20 Library Resource Roundup. It was a great day! Thank you to everyone who came to my presentations. And a special thank you to those who came for multiple presentations. As I always say, the best compliment that I can get is when you have seen me present and you come back for more. Here are the slides from the presentations that I gave today.
