You Stepped in Lava is a awesome game, that will  put a smile on your face. It will also teach you about, the cretaceous period. How you play is very simple and easy to learn. Fun for the whole family. You stepped in lava was created by Nate  and Justin.

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.

Today in class I poured off some of the water from our flotation analysis of the last of the bag. I found many species of snails with shells from 1-3 mm in length.  The next step is to research the names of these snails.

Today was awesome! Everything was better than expected. An intact shell was
found before we really even started. The sample was just like I expected, except, there
was much more to be found than I thought there would be. There was sticks and some
small grasslike things for flora, what my group found the most of. I also found a weird
small orange thing, it was very interesting to look at. So far this year, for first days of
projects, this was the best.

Using our stereo microscope, an image camera, and the Smartboard, students were able to observe remnants of a late Pleistocene organism.

Mrs. D and Students Dig in!

Students are doing some gentle examination of the dry matrix material, and are beginning to separate the material for future examination

Today our class was excavating the matrix dirt sent from Cornell University. The dirt was surrounded by a 10,000 year old mastodon and now located at the Ithaca Museum of the Earth . The Matrix did not look like what I expected to look. I thought it was going to look like fresh dirt, but it actually looked like a dry clay substance. I found very interesting objects during session 1 observations. I found twigs, shells, and an a object that looked somewhat like a rock. I am very excited to dig thought the dirt and find fascinating things!
