Forest Growers: Second Graders Plant American Chestnut Trees

Four chestnut trees traveling to the park by bus.

Bart Chezar and the Prospect Park Alliance arborist, Howard Goldstein, made it possible for our chestnut trees to be planted by BNS students. Amanda's class planted trees for the entire grade in a sectioned off area of Prospect Park between 15th and 14th Streets along Prospect Park West.

Meet the Scientist: Reyhan Mehran, Marine Biologist

Coloring a 20 foot great white shark is exhausting.

K students research sea critters to see if they can live in the class aquarium. With the support of staff and parent volunteers Jia and Jillian, each student has a chance to use books and the internet to find out about their animal of choice. Ranging from jellies to sea stars to great white sharks, students wind up making a life size model of their animals.


Students wrote about questions that they still had.

How do shells get on the ground?






How does the water go?

How does Reyhan know/learn about animals?



How does the ocean get its water?

For the second year in a row,  Reyhan Mehran, a parent and a marine biologist showed up to answer student questions.  (A favorite:  How many people have walked on the beach?)


Reyhan mobbed by scientist groupies.

Oyster Update



In November, 2017,  Robert Buchanan of BOP dropped off two new cages of oysters...10 strings in each.  By Boat! How cool is that!

























In December 2017, Josh's and Cora's class checked on our oysters. 















We took the baseline data on the oysters.
Then we returned, on May 25, 2018.
This time Nneka's class took the lead.




 To our horror...not one oyster was alive.  Not even a single oyster drill.


 We decided to clean the cages and the oysters.  












Robert Pincus, scientist and BNS parent, decided to sort and have students photograph shells.  Could we get clues from their condition as to the cause of their death?





 We collected data on water chemistry, temperature and turbidity.





Another scientist, and BNS parent, Barent Roth helped students survey plastic that they found earlier in the year.  And collect and analyze new samples.






















Some Student Photographs



























Sad to say not much life.  A dead shrimp was found.

Update:  Robert Buchanan reported that there was a lot of die off this winter.  .
