Digging for Dinos – Ms. Trowbridge’s class

It’s been a while since our class has posted.  Let’s catch you up!

After we finished our ScribblePress books about our favorite dinosaurs, we started to learn about how the dinosaurs might have become extinct.

One day when we got to school, we saw that someone had taken the dinosaur bone that we found in our school garden out of our classroom.  This person left behind some clues…

Muddy footprints.


A walkie talkie.


And, a tie.


We used the clues that were left to try to figure out who could have taken our bone.


After looking at our evidence we made a claim that we thought Mr. Brengard took our dinosaur based on the evidence we saw in the classroom.  All of the 2nd graders asked Mr. Brengard to come to a meeting so we could ask him if he had our bones.

Students presented their claim and backed it up with evidence to Mr. Brengard.


Turns out Mr. Brengard borrowed our bones to show some visitors to our school and he forgot to tell us.  The bones are back!!!


Since we have now learned about making claims and proving those claims with evidence we started talking about the possible ways the dinosaurs might have died.

We looked at four possible ways the dinosaurs might have died:  asteroid impact, a super volcano, radiation from an exploding supernova, and ice age.

Each day we focused on one theory and wrote about the claim and the evidence scientists used in our Dinosaur field guides.



Chris explains the 4 theories to Mr. Brengard.


After Thanksgiving vacation, students will pick which claim they think is most likely and will write an informational paragraph about that claim and citing evidence to prove it.

We’ve also been working on measurement skills.  Teams of students had to create their own dinosaur using specific measurements given to them.



Bin’s group created a “mixosaurus which is a mixture of the 5 dinosaurs that we studied.”
