Cool Pictures
how many turtles would you find in that particular hole?
with regards to the math question, i drew two circles and i marked two points where they touched, does that make any sense?

Hi Kailen,
We had a total of 49 turtles hatch from that particular nest - that's a lot don't you think. Each turtle lays anywhere from 50 - 70 eggs at a time.
As far as the math question - well done - the most number of times you can get 2 circles to intersect is two times! My students - start thinking circles to help you answer y math challenge question.
Hi Fiona,
Your geometry class is taking their test now. We cannot wait to see you tomorrow. or maybe hear you. We cleaned up the math center so you can bring friends along to see where we are.
Take care.

Good luck on the test girls. I'm looking forward to talking to you live tomorrow morning.
Ms. O'D,
You said that 49 turtles actually hatched from the nest- how many eggs were originally laid in order to yield 49 turtles. In other words, what's the survival rate for the hatched eggs?
During this hatching season, how often are you observing eggs hatching? (per day, per week, etc.)
Are you having fun? We miss you!!
Love, Katie G and Vicke
Hi Calc class!!! I miss you. So far I have just seen one nest hatch in the hatchery - they no longer take tke new eggs to the hatchery -The scientists will be gone before the eggs being laid currently will hatch so it is a waste of time. We still have nests hatching on the beach every night - we ususlly don't see those hatching, but we see the tracks the hatchlins leave on their way to the sea. The hatching success at the hatchery this year is 85.5%, which is good. It is probably a little higher on the beach since the process hasn't been tampered with in any way. Talk to you soon.
those are such cool pictures! :)
those pictures are extremely cool, i wish i can experience that one day!
MS OD!
How many eggs do you find a day?
- Allegra
Hi Ms. O'Doherty,
How large are the turtles in comparison to their mothers? How many eggs are you expecting to hatch successfully?
Have a good time!
Anna
Hi!
Hope you are having an amazing time in Costa Rica. I was just wondering what the average temperature of the water is where the sea turtles live. Thanks!

hey ms. O'D,
i just wanted to know whether or not the turtles were right on the beach where the people actually bathe or if they are somewhere more reclusive. if they ARE right on the beach, do the people who go to the beach approach them? are they able to interact with them or are there laws that don't allow anyone wcept for the researchers and students to go near?
hope you're having an AMAZING time!!
much love,

Hey Ms. O'D,
I hope you are having fun in Costa Rica. I was just wondering if the people in the communities around the beach where the egg's are laid make sacrafices for the good of the turtles. For instance, do they refrain from using motor boats and fishing nets to help protect the turtles. Also, I'm having some trouble calculating the CCL and SCL for one of the sections of the packet. If you could spare a few minutes from your busy, turtle-saving days, I would greatly appreciate some advice. Thanks. I hope you enjoy having an AMAZING time.
xoxoxo,

Dear mrs. S
Super cool pictures! you are so lucky! Do you know what the turltes feel like because they look pretty slimey and rough! EEP. I need to know
Daisy
Hi Allegra, Thanks for the comment. We count the eggs as the turtle lays them at night. She generally lays between 50 - 70 eggs at a time and she scomes to the beach every 10 days or so to lay eggs. So that would mean she lays eggs about 7 - 10 times in the season. I will give you the current statistics for Playa Grade this season so far.
Total number of nests on beach - 428
75 different turtles nesting on the beach this year, 27 of which are new turtles this year.
853 hatchlings were released from the hatchery and the hatching success from the nests on the beach is 85.5%.
Hi Anna - Great to hear from you. I had a chance to weigh some hatchlings a few nights ago - they averaged about 50 grams. They are like little mini-me's of the adults. The adult females weigh about 450 kg and can go up to as high as 600kg. That's a lot of turtle!
Ana, How are you doing? The water here is quite warm, but the amazing thing about leatherbacks is that they can swim in any temperature water. Even though they are reptiles they are classified as Giganotherms which means they can regulate their body temperature, just like the dinosaurs.
Hi Carolina and Katie - It was great talking to you today! Hopefully your questions were cleary answerd during our vidoe conference. Looking forward to seeing you all on Monday.
