Hi! My name is Ms. Thompson. I am a third grade teacher at the Collegiate School in New York. Join me as I study bottlenose dolphins in the waters of Greece!

A Dolphin Day!

"Dolphins-12:00-400 meters!" shouted Panni. We all immediately took our spots and held on tight as Joan sped to the place where the dolphins were located. Four beautiful dolphins were swimming in the area. Panni and I were in charge of entering the data on the palmtop, which is no easy task. We record group size, how close they are to the boat, if there are birds nearby, and if the dolphin is a newborn, calf, juvenile, or adult. We saw three adults and one juvenile. While Panni and I were inputting the data at the end of a five minute interval, Joan took photos and everyone else shouted out when they located the dolphins in our focal group. Locating them can be difficult because when they go under the water it is hard to tell where they will resurface. During our journey we were also lucky enough to see two sea turtles.

We returned to the research station with four different dolphins to identify. It wasn't easy and it took us a long time. Stefan and I were on a team again competing against Marie-Claire and Cas. I am sorry to report that Stefan and I did not win this time. What do you think made it difficult to find dorsal fins that matched our dolphins?

After all of our hard work was finished we had some free time. Marie-Claire, Cas and I explored the village. We stopped into a store that sold some very nice sandals. Can you guess who bought a pair?

Shopping in Greece it can be a little tricky because they use Euros instead of dollars. How many dollars makes up a Euro? If the sandals were 20 Euros, what would they cost in dollars? What if they cost 50 dollars, how many Euros would I need?

Hi again, Mrs. Thompson!

It was so fun to Skype with you again today. We hope your sunburn doesn't hurt too much. Remember sunscreen tomorrow!

Our answers to your questions are:
1) Some of us said that if the dolphins are related (like mom and child) their dorsal fins might look very similar. We noticed that when we were doing our dolphin identification activity with Mrs. Kahn. Some other boys thought that the choppy water might make it hard to get good pictures.

2) Even before you showed them to us, we knew YOU were the one who bought the sandals. Ms. Z. told us that you LOVE shoes (she said you have pretty toes, too!).

3) A few of us are going to figure out the dollar to Euro problems and get back to you.

We can't wait to see you on Monday. Next journey . . . Fairview Lake!

Well I wonder... I think you wanted me to know about your shoes! I can't wait to hear more about why we shouldn't eat fish. Please put on your sunscreen tomorrow! Mrs. H.

Hi Ms. Thompson from 1B! We are wondering how long you are usually on the boat before you see a dolphin. How is it in Greece? Can you tell if the dolphins are female or male and we are wondering how you can tell if the dolphin is an adult, juvenile or calf? It seems like you have collected a lot of data so far and have learned a lot! You are so lucky that you got to see a sea turtle. We love the pictures! We miss you and can't wait to hear all about your journey!
Love Ms. Bocchetti, Ms. Sullivan and 1B

This is 2B Library.
We read a book on dolphins, Dolphins on the Sand.
How big is the body of water that the dolphins are in?
How many hours do you work searching for dolphins?

We loved skyping with you on Thursday, Mrs. Thompson! We already knew that you had bought some sandals because you showed them to us!

We were talking about the dorsal fin matching and were thinking that maybe it is hard because the fin might have changed slightly since the last time you took a picture. Also, the differences could be so small that it could be hard to tell.

We did some tricky math to figure out how much the shoes would cost. When we looked it up, it was 1 Euro to 1.33 dollars, so we rounded up to $1.50. This is some complicated thinking, so we might have to get back to you about how much money you really spent!

We miss you and can't wait to see you!
