Ryann Rossi, explains the symptoms of disease that is often seen in plants and even the mangrove trees. The most common symptom in mangrove trees in the Bahamas is necrotic or dead tissue.
Ryann Rossi, PhD Candidate at North Carolina State University explains to Forest Heights Academy students how they will isolate the potentially diseased lesions on their leaves.
Forest Heights Academy students get a chance to touch the agar in a test plate to see what it feels like. Most students have never touched or seen agar before. Students will not be able to touch the agar in their own plates or else they will contaminate their samples.
Before students begin "plating" their potentially disease leaves in agar, they first must draw their leave and label the areas where there are lesions present.
Partner from North Carolina State University, Ryann Rossi helps students to set up and sterilize their station.
FRIENDS of the Environment Outreach Officer, Cassandra Abraham helps Forest Heights Academy student to cut a small section of his potentially diseased mangrove leaf that includes diseased and non-diseased sections of the leaf.
Students at Forest Heights Academy label their agar plates so that they can later check their plates after 3 days, 1 week, and 2 weeks to see if there is any type of fungus growing.
Here is an example of a diseased mangrove leaf drawing from a student at Forest Heights Academy.
Students at Forest Heights Academy sterilize their tools before isolating the diseased portion of their mangrove leaves. Students will grow these isolations in agar plates to see if there is fungal growth present, which could indicate that the mangroves are diseased.
Students at Forest Heights Academy sterilize tweezers and scissors over an open flame before they use them to cut or pick up the diseased mangrove leaves. This prevents contamination.
Student at Forest Heights decontaminate a pair of tweezers by burning it over an open flame.
B.A.M. year 2 student from Forest Heights Academy proudly shows off his plated mangrove leaf. Now all he has to do is wait to see if fungus will begin to grow.
Forest Heights Academy Marine Biology student carefully uses a scalpel to cut or isolate a small piece of his diseased mangrove leaf. The student will place the leaf in agar and wait to see if fungus grows.
Ryann Rossi, PhD Candidate at North Carolina State University helps a student at Forest Heights Academy to isolate a piece of his diseased mangrove leaf.
Forest Heights Academy student isolates two pieces of his diseased mangrove leaf. These leaf pieces will now be placed in an agar plate.
A potentially diseased leaf that has been dissected by a Forest Heights Academy student for the B.A.M. year 2 disease experiment.
Forest Heights Academy student sterilizes a pair of tweezers before she picks up her mangrove leaf isolations and places them in an agar plate.
Students at Forest Heights Academy further sterilize the mangrove leaf isolations by placing them in a bleach solution for several seconds before transferring them to their agar plate.
Science is fun especially when you get to use interesting scientific tools and different methods!
To prevent bacterial contamination, Ryann Rossi, PhD candidate at North Carolina State University shows students how to seal their agar plates with Parafilm.
