Celebrating Ada Lovelace Day

I can’t really figure out why, but the second Tuesday in October is celebrated annually as Ada Lovelace Day, a day to recognize the accomplishments of women in STEM and encourage women and girls to explore STEM careers. (It’s definitely a worthy day I just don’t know why it is this particular day. She was born Dec. 10, 1815 and died Nov. 27, 1852, so the day had no clear connection to her.)

It’s a great day to celebrate the legacy of Ada Lovelace, the daughter of the poet Lord Byron (though he was not involved in her life and her education was directed by her mother) who was a pioneer in early computing. She worked with Charles Babbage on his proposed Analytical Engine, a general-purpose computer that was never built. She recognized that the computer could be used as more than just a calculator, and she wrote the first algorithm for a computer to follow, making her the world’s first computer programmer.

Science Sparks has a good printable fact file on her that you can use to get started learning about her and her accomplishments. Kids Konnect has fact sheets and printables you can use in the classroom or at home to talk about her life and work.

Get a free set of printable punch card numbers to use for number recognition with an early-computing twist from Playground Parkbench.

Teach Starter has a basic coding activity using pattern recognition that little kids can do. Any activity involving coding without a computer would be a great thing to do to celebrate this day. Or use scratch to build a poetry generator, with this project from the Raspberry Pi Foundation.

If you need more resources, there are tons of printables related to Ada Lovelace on Teachers Pay Teachers, including reading passages, coding projects and other STEM activities and more.

Human brains are pretty amazing, allowing us to think, feel, create, communicate, move and more. But humans aren’t the only animals with cool brains, as Crab Museum explains in the book The No-Brainer Brain Explainer (illustrated by Bruno Valasse).

This book, aimed at kids in grades 1-4, is colorful and silly but also educational about how brains actually work, with billions of neurons sending electrical and chemical signals around the body.

“Everything we think, feel and experience comes from an electrical relay race, with neurons passing chemical batons to each other,” the book says. “The constant chatter of billions of brain cells creates your entire world.”

The book compares the brains of mammals to those of crabs (the book is “written” by a crab after all) and notes that crabs have fewer neurons and of course are much smaller, but they have separate parts of their brains that control their eyes and their legs. Crabs are also capable of remembering things, using tools and solving puzzles.

Some animals’ brains allow them to know more about their world in different ways from humans, such as spiders being sensitive to vibrations in their webs and catfish having an amazing sense of taste, with taste sensors all over their bodies.

It notes that 95 percent of brain activity goes toward things we do unconsciously, like breathing, walking and catching a ball flying toward us. It also talks about dreams, memory, how our emotions try to predict the future, where brains came from and fun facts about brains. For example, did you know a sperm whale is believed to have the biggest brain of any creature that’s even lived? Their brains weigh 18 pounds, compared to just 2.5 pounds for humans.

Information on what creatures have the smallest brains, the toughest brains, the most brains and those who actually eat their own brains will delight kids (and maybe gross them out a little bit). They’ll also enjoy learning about the mycelium network of fungi, which is like a brain without a body, and slime molds, which are like a brain without a brain.

It ends talking about why human brains are so special because we’ve found ways to work together, communicate and build communities on a scale bigger than any other animal.

Kids and adults alike will enjoy this colorful, silly and informational book about brains!
