A heads up for our readers…in addition to eggs and nests, this post contains multiple images of bird taxidermy, which some may find unsettling. If you do, no problem! Skip this particular post, and we’ll see you on the blog next Tuesday!
Deep within Princeton University’s Department of Ecology and Evolutionary Biology, there is a plain door with a fairly innocuous sign mounted nearby:
Behind that plain door, however, is an amazing treasure trove of natural history. It’s the Princeton Bird Collection, which contains a taxidermy catalog of over 6,000 bird specimens, some of which are over 150 years old! Many were collected by William Earl Dodge Scott, who was appointed Curator of the Department of Ornithology in 1879.
Princeton’s bird room contains a multitude of hulking gray metal cabinets. While I’m used to our library’s special collections cataloged and ordered on regular bookshelves, the bird room’s cabinets open to reveal horizontal wooden drawers containing various specimens. These collections are available for teaching and research, including the Stoddard Lab’s research on avian coloration and morphology.
The drawers also contain nests and eggs, which are similarly laid out for researchers:
There are larger nests as well, including this amazing one that I’m pretty much ready to curl up and take a nap inside:
Beyond the drawers are a fantastic assortment of standing taxidermy, both large and small. Below are just a few the staff unwrapped for me to photograph…from top left to bottom…an emu, ground hornbill, kiwi, barn owl, macaw, snowy owl, and golden eagle.
And check out this! It’s a quetzal, which hails from Central America. It was was considered sacred by the Ancient Mayas and Aztecs. The photo really doesn’t do it justice. The coloring on the bird is simply exquisite.
The bird collection also contains the documents and journals of Charles Roger, a professor of ornithology at Princeton from 1920-1977. The journals, which he began as an eager boy of eleven and continued until he was eighty-four are a fascinating and informative body of work. You can read more about the digitization of his works, and find some awesome coloring pages from our special collections here (as well as a couple fun bird projects!).
A very special thank you to Cassie Stoddard, Assistant Professor in Ecology and Evolutionary Biology, for arranging for me to photograph the bird room, and answering my questions about ducks!
We’ve all wanted to jump into books. Who doesn’t, for example, want to go to Diagon Alley and hit the shops? Join Hazel for stories in the Honeycomb? Explore Babilonium with Candy Quackenbush? Or sail the skies with Matt Cruise on the Aurora? Part of my job at the 
But before I get started on all the details, I’d like to introduce our event collaborator, 
Bedtime Math brought 3 fantastic activities to the event: Spy Training, Beach Ball Party, and Glow-in-the-Dark Geometry. Here’s Spy Training, which was all about codes and ciphers…
And here’s Beach Ball Party, which involved counting, stacking, and chasing beach balls determined to make a break for it.
It also involved Ellen Williams (who you last spotted being pelted with marshmallows in 
Some kids decided to use the original plastic connectors that came with the bracelets to make unique geometric creations. Here’s one of my favorites. A series of loops that, when spun, becomes a sphere!
The mines were stocked with an assortment of wooden numbers. I used 4″ numbers I found online at Woodcrafter. If you’d like a cheaper option, I recommend printing paper numbers on card stock.
The mines were staffed by high school volunteers from the Arts Council, who were suitably decked out in miner helmets.
Elsewhere in Digitopolis was the “Fibonacci Forest,” hosted by the 
The Watershed also did a cool fractal tree project. It involved a half-sheet of green paper, brown markers, and rulers (here are the 
We decorated the finished fractal trees with bird and leaf stamps, but you can also just use markers or color pencils.
And speaking of wildlife, how about some zebra math? We were delighted to be joined by Princeton University Professor 
Some researchers believe that zebra stripes exist to confuse predators. So Dan and his constituents developed “Dazzle Confusion,” an iPad game in which kids “become the lion” and tried to tap black, white, or striped moving targets to determine which one is most difficult to hit.
At the end of the game, the program tabulated the kids’ results and displayed them on a large screen. As the event progressed, the results continued to accrue. This lead to conversations about data collection, measurement, central tendencies, and averages.
It’s worth noting that although there was much variation on kids’ “strikes” on the targets, there was a strong trend (p < .08) showing that the striped targets were hardest to hit! How’s that for some real world math?
Here’s a screen shot of the game, which was created by sophmore Lucy Lin. If you’d like to test drive the game yourself, here’s the 
The game was cool, but even cooler was the fact that there was another laptop running tandem to the gaming laptops that showed all the algorithms behind the Scratch program. And volunteers were on hand to answer any and all questions about computing. They also had a couple of encryption puzzles for kids to crack.
For those who prefer their math undiluted, the Princeton University Mathematics Club came out en force to host a “Playful Problems” table. Here, kids found a plethora of logic puzzles, word problems, visual puzzles, calculator tricks, the works!
There were 12 different activities for children ages 4-10. The activities ranged from easy to moderately difficult. Here’s an example of our simplest puzzle, which was created by Casandra Monroe (whom you first met 
Below is a list of what we offered at the event table. In addition to using Google to find some of these puzzles, Math Wizardry for Kids (Barron’s, 1995) and How to be a Math Genius (DK Children, 2012) were terrific resources.
By the way, did you notice the cute play cart parked in the upper right corner of the above image? That’s one of our “Trio of Treats.”
I always try to include something for the littlest patrons, so I bought 3 adorable food carts and stocked them with math play sets. The food carts are by KidKraft (Sweet & Sunny Lemonade Stand) and the play sets are by Learning Resources. We used Piece-A-Pizza Fractions, Number Pops, and Count ‘Em Up Popcorn.
One of the most popular event tables, however, was “Visit the 4th Dimension.” It was hosted by 
At the event table, kids learned about the different dimensions (1st is a line, 2nd is a square, 3rd is a cube, 4th is a tesseract). ScienceSeeds brought their 3D printers to the event and made models. You can see a tesseract in progress below. Awesome.
Kids could also make 3D models of their own using drinking straws and plastic connectors. You can buy the plastic connectors online (from Strawbees). However, scienceSeeds has a die cut machine and was able to purchase the die cuts (from Accucut) and make their own connectors from plastic sheets (from Grafix).
Like I said, their table was hopping – they estimate they went through at least 3,500 straws!
The thing I liked most about the project is that there was no limit to the shape, size, or intended use of the 3D models.
