Day Six: Classroom

​Today we went into the classroom and learned about different types of coral diseases and what can make coral sick. We completed a few fun activities to visualize what is happening to the coral reefs. We learned all about carbon dioxide’s effect on the ocean and it’s magnificent creatures.


The first activity that we completed was the quadratic analysis of bleached coral populations. We learned all about global warmings effect on the coral. Increased temperatures of the ocean make the zooxanthellae (algae) leave the coral. The zooxanthellae give the coral it’s stunning color. When it exits the coral, the coral then appears to be bleached. For the quadratic analysis we were given a picture of a coral reef and then a five by five grid to place over the picture. We then had to figure out which coral colony is bleached or in the process of bleaching.


We also learned that the increased carbon dioxide increases the acidity of ocean water. This is because the ocean absorbs 1/3 of the carbon dioxide realized by man made activities. To help us visualize this, we were given a cup of water with a straw in it. In the cup was a blue indicator mixed in with the water. When we would blow into the indicator it would turn from blue to a deep yellow. This is because humans exhale carbon dioxide. So as we were exhaling, we were increasing the acidity of the water.


We learned how to identify if coral is healthy, paling, or bleached. We did this by holding up a chart to different colors of coral and identifying how healthy it was.We also played a fun review game of Pictionary. We reviewed different species of fish and coral.


We learned tons of information during the classroom today! And are extremely excited for what tomorrow will bring!

Last moments in paradise

We started the morning by waking up at a harsh 3:30 a.m.. We left around 4 to began our short ten minute ride to the airport. We returned our rental car once we arrived at the airport and traveled to the bag check and security. After waiting about an hour we began boarding at 5:30.     After a short taxi to the runway, we departed from Tampa at exactly 6:26. While we were in the air we got to watch the beautiful sunrise from the East. Overall the flight was good, very low turbulence if any. We began our initial decent at 7:57 and landed at 8:20. Sad to see this field trip end. I just want to thank Mr. and Mrs. Park for making this an experience we will all remember for the rest of our life. I am also so grateful for all the memories with these amazing girls. ​ By: Hanna Surfus

February 25, 2023: Arrival in Florida!

Image
​Our first day in Florida was a success! We had a wonderful flight from Indianapolis to Tampa, and then enjoyed lunch at Chick-fil-A. We were all able to register for TSA pre check, which made a much easier experience of getting through the airport without stress.  Three members of our group had never flown before, but it was a great first-time experience for them, as our flight went smoothly. We arrived in Tampa around 11:30, so we were able to get a great start on our day from there! Then, we traveled north to Honeymoon Island for a beach day! We were able to appreciate the 86 degree weather, cool off by swimming in the ocean, and scavenge for interesting shells along the shoreline. We found many of those, as well as sand dollars and coral! After leaving the beach, we drove to Crystal River and checked in to our hotel before going out to dinner at Peck’s Old Port Cove. There, we ate lots of seafood.  It is safe to say that this was the perfect start to our field trip, and we...
