National Eat a Cranberry Day is today! Traditionally served at Thanksgiving, cranberries are packed with antioxidants and nutrients. The berries release those nutrients best when they are raw, but they are definitely tart! Children could learn about the cranberry bounce test.
Fibonacci Day is today! The mathematical Fibonacci Sequence is a pattern of numbers where the last two numbers are added to make the next number. So.. 1 + 1 = 2; 1 + 2 = 3; 2 + 3 = 5; 3+ 5 = 8; 5 + 8 = 13; 8 + 13 = 21; 13 + 21 = 34 and so on and on…
So how is today Fibonacci Day? Today is 11/23, the start of the Fibonacci Sequence.
What do we do with the Fibonacci Sequence? Many scientists have found examples of the series in nature, such as the arrangement of petals within a flower. Children could view a great TED talk about Fibonacci Numbers at: Fibonacci Numbers. Kids also have fun just extending the pattern to very large numbers. So…you still want more information? The sequence is named after Fibonacci (real name Leonardo Pisano Bigollo), a famous Italian mathematician who lived from around 1170 to 1250. He did not invent the series, but he did broadcast it via his books. He is also famous for spreading the Hindu-Arabic math system, the system we use, throughout Europe.

Jenny Coupler Patent
Jenny Coupler was patented by Andrew Jackson Beard in 1899. The African American inventor knew how dangerous it was to couple railroad cars together because he had lost a leg in a railroad car coupling accident. His invention allowed cars to join together by bumping into one another and thus saving many human hands and feet. He sold the rights to his patent for $50,000. Children can examine his patent at: Jenny Coupler Patent.
