John Urschel is a young man with several seemingly disparate characteristics and talents. He is an athlete and a mathematician and he is a black man and a mathematician. He loves what he does and he is good at it all.
In this activity, students can learn about this mathematician and retired pro football player as they read to create a timeline of his life and accomplishments. They compare his milestone to the milestones that are usually met in schools.

What's your guess? How fast are the number of daylight hours changing each day? Are the changes dramatic or subtle?
Students make guesses; compute how long, on average, the change in daylight hours should be; and finally understand the variability in our year of daylight hours.
