We’re in the paper!

A big thank you to the Brighton Pittsford Post for coming to Allendale Columbia School to learn about the Mastodon Matrix Project! The online article can found here : Allendale Columbia students have their hands in history


Pete’s summary of the Project

Posted: January 24, 2013 by Tina Duver in Sorting and Blogging

In Mrs. Duver’s class, I have been looking through matrix from a mastodon site.  Matrix is the mud around the bones. Other classes in different schools have looked through different samples of matrix. We have found lots of different things. We started with around 26 children sorting the matrix. I found twigs, leaves, seeds, rocks and at one point I actually found a hair. We also found some grass. We sorted the matrix into flora, fauna, rocks, and unknown. After sorting them we measured and weighted some of the things that we knew were rocks. Next we floated the matrix in water so that the organic material would float to the top. We looked at some of the matrix through microscopes. We took notes and wrote down what we found. One group of students in Mrs. Duver’s class found a green leaf. Some of the things we found were similar to what the other school groups found. I liked being able to do this project. I weighted and counted the rocks that the whole class found. We then put the different sizes of rocks in different bags. We are beginning to get ready to ship them back to the PRI.

Scientists know that glaciers in the Pleistocene period wiped out all earthworm species present in Canada and the Northern Continental United States. The line the glaciers extended to in this period is known as the Wisconsin Glacier Line. The Southern limit of this line extends across Southern New York and Northern Pennsylvania. The Mastodon in our mastodon project might have been found very close to that Southern New York Line!

Here is a picture that Nicole was able to take with her iPad through the lens of the Stereoscope!!  It looks just like a worm to us, so we sent a picture to Dr. Buckler to get her thoughts.

Let the sorting begin!

We have floated our first entire sample- all 1 kg of matrix! We are now in the beginning stages of preparing what we found for the online database.  We are dividing the samples into the following groups in bags.

Twigs (different lengths)


Rocks (of 3 different sizes)

? Mysterious material (we have no idea what it is!)


Root material


Animal remains (insects, wings – bug parts)

We will continue to divide these containers and measure them to even further classify them!

I think the mastodon project is going really well so far. The reason being that all the six graders are cooperating very nicely with each other. I am happy we are breaking up the groups because we all get the chance to do different things and experiment on our own. I really like to have the matrix in my hands. That right there is history in a different form. And by the way, if anyone thinks it’s impossible to find something like ivory:


Today, AnnMargaret, Maeve and I were looking at some really cool rocks that a almost see through. Mr. Theuer told me they can be angular, sub angular, sub rounded, and rounded. He told me that the more round they are, they have been pushed around by water. I thought this was really cool. More Coming Soon!!! 😃😁

Rock Sorting – It Rocks!

We sorted rocks today according to size.

We sorted rocks today according to size.

Today in class we sorted rocks. That may seems like a simple and pointless task, but it is important.  For our research we needed to separate the rocks into 4 groups:

1. less than 2 mm

2. between 2 and 8 mm

3. Between 8 and 32 mm

4. Greater than 32.

We have ONE rock in our “Greater than 32 mm” container.  We found a piece of glacial chert in the samples today, which was pretty cool!!
