Happy Ada Lovelace Day!

Posted on by

BY KATIE ZONDLO

Every year on the second Tuesday of October, the world celebrates Ada Lovelace Day, which honors the accomplishments of women in science, technology, engineering, and math (STEM). Started in 2009 as a way to inspire future generations of girls to enter STEM fields as well as support the women already working in STEM careers, groups now host gatherings, conferences, workshops and social mixers that appeal to audiences of all ages.

The day is named after Augusta Ada King, the Countess of Lovelace (1815-1852), who is considered the first computer programmer. Using an early general-purposed computer called an Analytical Engine, an instrument envisioned by her friend and mentor Charles Babbage, Ada recognized the 19th century machine could be used for more than just general calculation. She poured over numbers and figures to create an algorithm for the not-yet built computer. Unfortunately, the Analytical Engine was never completed, so Ada wasn’t able to witness the success of her program.

Nearly a century after Ada wrote her algorithm, modern day computers tested the software and discovered there was only one minor mistake that could be easily corrected. The program was almost perfect. In the late 20th century, the United States Department of Defense developed a common computer programming language that was named Ada, in honor of Lovelace and her contributions to the field.

We’re celebrating today by highlighting award-winning author and Princeton alumna Laurie Wallmark’s picture book biography, Ada Byron Lovelace and the Thinking Machine (Creston Books, 2015). Recipient of the National Science Teachers Association’s Outstanding Science Trade Book and the California Reading Association’s Eureka Book Award, you can find it read here by Story Time With Michele. The book’s truly gorgeous illustrations are by April Chu. Laurie has authored several more books about women in STEM, such as Kalpana Chawla, Judit Polgár, Grace Hopper, and Maria Mitchell!

Ada Lovelace is also featured, along with four other famous scientists, in the virtual escape room I designed, The Discovery Museum.

Pepper’s Ghost, Part II

Posted on by

this hummingbird 1_edited 1This is not the first Pepper’s Ghost illusion to appear on Pop Goes the Page. Back in 2020, we posted a kid-friendly version featuring a spirited fox. The illusion is basically a reflection trick, but it’s very effective when done right!

seeing spirits   You’ll need:

  • A clear plastic drink container lid
  • Paper (heavier paper or thin cardboard works best)
  • A small section of clear plastic (like the lid of a food container)
  • Scissors and pencil for construction
  • Cell phone

The project was originally designed and posted by artist Joshua Ellingson on his Instagram. First, wash a clear plastic drink lid. Then cut a half circle template out of paper. When you have a half circle that correctly fits at a 45 degree angle inside your cup lid, trace the paper template onto a piece of clear plastic. We used an acrylic gift box, but plastic food containers work great too. Tape the plastic half circle inside the cup lid. The hardest part is getting that 45 degree angle just right. I made about 4 templates before I finally nailed it. Here’s my finished cup with the plastic half circle:

Head to YouTube for a Pepper’s Ghost illusion on a black background. We tried a couple different ones, but had the most success with this hummingbird. Cue up the video on your phone, maximize it to full screen, and lay the phone on a tabletop. Place the cup lid on top. Finally, roll the video and turn off the lights! Your object will appear to float inside the cup lid! It’s really quite remarkable.

The original designer, Joshua Ellingson, also made a GIANT version of this craft with a thrift store bubble chair and his flat screen television. It’s a must see! And Disney’s Haunted Mansion famously employs this illusion, including an entire ballroom of ghosts!

Sanitation SUPERSTARS!

Posted on by

It’s a big job, but our stellar sanitation team is up to the task! Drive your garbage truck to multiple locations around town, then head to the city dump and send everything flying down the chute. Yes we made a mess, but we had SO much fun!

We read Trashy Town, written by Andrea Zimmerman & David Clemesha, illustrated by Dan Yaccarino (HaperCollins, 1999), and read here by Michigan City Public Library. Mr. Gilly is a trash man and wow is he is busy! There are lots of stops all around town (like the school, town park, a pizza parlor) and finally to the city dump to unload. But there’s still one more stop for Mr. Gilly after that…the bathtub!

This was a special final Tiger Tales story time request from a family who was moving out of the area. The story time kiddo asked for “garbage trucks” and “chutes” and we think we delivered!

You’ll need:

  • 1 large craft box (ours was 4.5” X 4.5” x 9” but a large tissue box works too!)
  • A box cutter
  • 1 sparkle stem
  • 1 toilet paper tube
  • Tin foil
  • 1 truck template, printed on 8.5″ x 11″ card stock
  • Black construction paper
  • Yarn
  • Hole punch, scissors and tape for construction
  • Markers for decorating

First, the garbage truck! Use a box cutter to make diagonal incisions in the back and bottom of your box, then fold the entire section upwards. This is your garbage truck’s loading hopper. In order to make it easier for kids to raise and lower the hopper, we looped half of a sparkle stem, then taped it to the tailgate.

Notice the garbage cans hanging on the side of the truck in the above photo? To make those, cut a toilet paper tube in half, then wrap each in tin foil. Punch a hole in the side of each can and hang them on sparkle stem hooks taped to the side of the truck. We filled our can with scrap tissue paper “garbage” as well.

The front of the truck is a template from this post (just disregard the roof section on the template – or better yet, cut it into little bits and use it to fill your mini garbage cans!). Tape that in place, then add some black construction paper wheels and decorate the truck with markers. Tape a yarn pull string to the front of your truck for hauling.

It’s time to get to work! We constructed models of each of the sites mentioned in the book…school, park, doctor’s office, pizza parlor, fire station, and the city dump. Many thanks to my daughter for helping me construct them (love the smiling pizza slice)!

We constructed the buildings and park with shoe boxes and box lids, but the city dump was much larger. It was big box with a removable chute that allowed kids to tip their garbage and send it sliding into the dump. You can see the whole thing here, modeled by our awesome grad student volunteer Shruti Sharma (who was also a cloud scientist at a library event this spring).

Once every kid had made a truck, they received a “route card” that showed the order in which they needed to visit each place. Since there were 5 sites, I made 5 routes, all different so they story time kids wouldn’t clump together. Each route, of course, ended at the city dump.

We placed the buildings around the library, and each had it’s own unique “garbage” to be collected. Mostly, these were little do-dads and art supplies from the cabinet. The school’s garbage, for example, are leftover wooden letters from this project. Caregivers and older siblings volunteered to staff each site, refilling “garbage can” cups as each truck rolled up, and the story time garbage kids got to work.

At the city dump, Shruti helped kids slide the garbage down the chute. The back of the big box was cut open, in case kids wanted to take their garbage home. It got a little messy and chaotic. But hey! It IS a dump after all!

If you would like to do this story time and don’t have time to make the buildings, no worries! Here’s a printable set of the buildings that you can tape to walls and tables. Drive safe, and happy collecting!
