|Research on sea turtle anatomy|
To get ready, all of us are learning a lot.
1. Sea turtles
We didn't know anything about sea turtles. Now we know a lot! Everyone had one question to research. We had to write research notes.
We had to get good pictures from the internet. We had to type everything.
We all had to make something to show what we learned.
|There are seven species of sea turtles.|
Some are endangered.
We put it all on a display.
That was this Wednesday.
|Facts about Sea Turtles|
What is that, you ask?
These are marine animals. Echinoderms are animals like star fish and sand dollars.

crabs are "living fossils" because they
have stayed the same for millions of years.
|Researching our topics|
We also learned about horseshoe crabs, which are "living fossils" because they did not have an upgrade in their design for a million years.
|We used books, videos, internet articles, and real shells.|
We made some more things for the wall. That was this Thursday.
3. Friday was Fossil Friday
Did you know South Dakota was once at the bottom of a big ocean? Did you know the Black Hills have a lot of igneous rock and also Milbank and Yankton have some? But everywhere else in SD it is metamorphic and sedimentary but mostly sedimentary?
Did you know that glaciers are like bulldozers and they pushed all the dirt, stones, gravel, and even boulders to this part of South Dakota from Manitoba, Canada? The glaciers also made the Coteau des Prairies. The glacial till is what we see: dirt, rocks, boulders, and gravel.
|Fish fossils from Colorado|
There was also a hard stone with a lot of sea shell fossils in it. We looked at the fossils with magnifying glasses.

|Almost looks real, doesn't it?|
- How are fossils really made?
- Where was the largest fossil archelon (prehistoric turtle) found in South Dakota?
- Who is "Sue"?
