Gold Fever

gold fever

It sparkles and shimmers. Could it be gold? Well, you might strike gold and get rich…or you might be fooled by some glittery pyrite! We made some awesome geology connections at To Be Continued, our story time for 6-8 year-olds, including rocks that sing!

We read Missing on Superstition Mountain by Elise Broach (Henry Holt, 2011). Brothers Simon, Henry, and Jack have moved from Chicago to Superstition, Arizona. The sleepy little town is shadowed by the looming and unforgiving Superstition Mountain, which has a history that none of the adults seem to want to share. The boys have been forbidden to go into the mountains, but when Josie the cat runs away, they follow her and soon uncover a mystery that involves three human skulls, a lost gold mine, and the strange, seemingly supernatural, power of the mountain. Can the boys and their friend Delilah survive Superstition?

In addition to a secret gold mine (which is totally awesome), Missing on Superstition Mountain has quite a bit about rocks, landscapes, and geology. When we finished the book, I thought it would be cool to do some rock-based activities. And Princeton University have some fantastic resources when it comes to geology.

department of geosciencesFirst, we took a walk across campus to Guyot Hall, home of the Department of Geosciences. Their central office space is lined with display cases full of rocks, gems, fossils, and minerals.

dinosaur skeletonBack at the library, I had samples of pyrite for the kids to look at (courtesy of Laurel Goodell, manager of the undergraduate labs in geosciences). Pyrite is called “Fool’s Gold” because of its sparkly gold appearance, but it’s actually a mineral.

pyriteThe kids couldn’t take home the big samples of pyrite, but I did find some smaller pieces on Amazon. I bought three, 0.2 ounce boxes of pyrite nuggets for $5.79 a box. They arrived powdered with black grit, so be prepared to do some major rinsing, and maybe a little scrubbing, before you given them to kids. But as you can see below, they cleaned up nicely and there were some pretty good sized pieces in there.

pyrite nuggetsThe kids took their stash home in a cotton drawstring bag (left over from this event). I also tucked a little information sheet inside the bag too (here’s the template if you’re interested). But I saved the best geology connection for last. Did you know that some rocks can produce musical notes?

lithophoneThis is a lithophone. It’s a xylophone with tone bars that are made out of stone (as opposed to wood or metal). When you strike the stones with a mallet, they produce a musical tone. But not all rocks sing! It takes a lot of trial and error, as well as a lot of chipping and grinding to make rock tone bars. The stones you see above are limestone, sandstone, and granite.

The lithophone was made by Tom Kaufman, owner of Tinkertunes Music Studio in Michigan. I commissioned him to build it for a Journey to the Centre of the Earth event in 2013. After the event, the lithophone went to its new home in the geosciences lab.

Ready for a little rock concert?


If you think that’s cool, you should check out Tom’s lithophone fence. It plays “Row Row Row Your Boat” as you run around it with a mallet! The fence was installed at the Gerald R. Ford Presidential Museum in Grand Rapids, Michigan for ArtPrize, an annual art contest.


Many thanks to Laurel Goodell and the Department of Geosciences for the pyrite and lithophone loan! 

Winter is Coming

winter is comingIt’s a diorama, a keepsake box, a mini exhibit, AND a lesson in ecology! Open the lid of this winter landscape and you’ll find the creatures that hibernate, burrow underground, and tunnel underneath the snow, complete with an information card!

open woodland boxWe read Over and Under the Snow, written by Kate Messner, and illustrated by Christopher Silas Neal (Chronicle Books, 2011). A father and child ski over the deep snow in the woods. Even though it’s a world of white, signs of life are everywhere – squirrel, owl, deer, snowshoe hare, and fox. But under the snow is yet another world. Shrews and voles run in tunnels. Bullfrogs burrow in the mud, bears hibernate, and a queen bee sleeps, waiting for the first signs of spring. The book ends with the child in a cozy bed, dreaming of nature. An absolutely beautiful book, with gorgeous, bold illustrations set against snowy white.

You’ll need:

  • 1 box with a lid
  • Brown construction paper
  • 1 woodland template, printed on 8.5″ x 11″ white card stock
  • An oval of blue construction paper (approximately 2.5″ x 4.5″)
  • An oval of silver mirror board (approximately 2.5″ x 4.5″)
  • A rectangle of brown wrapping paper (approximately 7.5″ x 10.5″)
  • A smaller rectangle of brown wrapping paper (approximately 3.75″ x 4.5″)
  • White cotton balls
  • 4 small clear plastic small gemstones (optional)
  • Scissors, tape, and glue for construction
  • Metallic markers for decorating
  • Hot glue

First, find a box with a lid. I used white cardboard pencil boxes with hinged lids from Discount School Supply (a dozen cost $17 so a bit of a splurge). To give the outside of the box a little pop of color, we put a strip of patterned tape around the perimeter, but this is optional (or, just use markers to decorate!).

Line the inside of the box (including the underside of the lid) with brown construction paper. Glue an oval of blue construction paper on the right side of the box lid. Cut and color the bear, bee, vole, shrew, and bullfrog from the template, and glue them inside the box. Use markers to draw burrows, dirt specks, and tree roots (we used metallic markers, and they looked great on the brown paper!). Glue the information card to the inside of the box as well.

open woodland boxClose the lid of the box, and glue an oval of silver mirror board to the right of the box, directly above the blue construction paper oval. If you don’t have mirror board, use tin foil.

Now for the tree! Use a brown marker to draw vertical lines on a tall, 7.5″ x 10.5″ rectangle of brown wrapping paper. Then squish, crinkle, and wrinkle the paper. The more wrinkly it gets, the better!

woodland tree step 1Roll the paper into a tube and secure it with tape. Cut 4 tabs in the bottom of the tube (each tab should be about 1.5″ long). Fold the tabs outwards. Later, you’ll use these tabs to attach the tree to the box lid:

woodland tree step 2Cut 5-6 tabs in the opposite end of the tube (these tabs are much longer, about 5″). Fold them out gently, then twist them to create the branches of your tree.

final steps woodland treeHot glue (or tape) the tree to the lid of the box. If you’d like to add a log to your landscape, use a brown marker to draw horizontal lines on a 3.75″ x 4.5″ rectangle of brown wrapping paper. Crinkle the paper, then roll the paper into a tube and secure it with tape. The final length of the log should be 3.75″. Set the finished log aside for a moment.

Glue white cotton ball “snow” to the lid of the box. Then cut and color the squirrel, owl, deer, snowshoe hare, fox, and tree leaves from the template. Glue these items, plus the log, to your winter landscape.

winter is comingFor some extra sparkle, I hot glued 4 small clear plastic gemstones to the edge of the lake. But this, of course, is optional.

frozen lakeYour winter landscape is complete! Well, maybe not quite complete…

A Little Batty

a little battyThis terrific poster board bat can hang just about anywhere, thanks to its paper clip foot. The bat is a little science lesson too – open its wings and discover a mini exhibition of bat information!

bat wings openYou’ll need:

  • 1 rectangle of brown poster board (approximately 6″ x 13.25″)
  • 1 bat template, printed on 8.5″ x 11″ card stock
  • 1 jumbo paperclip (mine was 2″ long)
  • 1 bug template, printed on 8.5″ x 11″ paper
  • Bat facts templates (more on those below)
  • Scissors, tape, and glue stick  for construction
  • Black marker

Fold a rectangle of brown poster board in half (we used brown because brown (and red) bats are the most common bats in NJ). Use the template to trace 1/2 of a bat onto the folded poster board. Use a black marker to draw eyes, a nose, and a mouth. Next, fold each wing inward, across the bat’s body.

bat stepsUnfold the wings and glue bat facts and bugs to the bat’s body. Two important things to remember: 1) Since the bat hangs upside down, you’ll want to attach the facts and bugs upside down as well; and 2) Keep the things you are gluing out of the creases in the wings. Otherwise, your bat’s wings will not fold as nicely.

We offered 4 different types of bugs (here’s the bug template again) and 6 different bat facts. Kids could pick and choose which bugs and facts they wanted to add to their bats. The facts are listed below, along with their templates.

to navigate through the dark night skies. ECHO! Echo! echo!

Once your facts and bugs are glued, grab a jumbo paperclip. Bend the inner part upwards until the paperclip forms a 90 degree angle.

paper clip footTape 1/2 of the paper clip to the back of your bat, right at the very bottom:

taped paper clipOK, your bat is ready to hang! Place the free end of the paperclip onto a shelf or tabletop. If you’d like to hang the bat on your shirt, on a nail, or on a garland with other bats, adjust the paperclip accordingly.

I designed this project for a “Bats in Your Backyard” table at a library event in 2013. The table was hosted by the Conserve Wildlife Foundation of New Jersey. The foundation put together an amazing table packed with information about bats. And check out the bat houses on display!
