How can  I  integrate Macro-biology and microbiology in my "adopt a tree" project.

Project Assignment:  "Adopt A Tree!"

Purpose:  To investigate the diversity of macrobiotic and micro biota of an unknown tree and it's environment.

Overview:  Before this workshop, I had my students study their tree from a macro-biological level.  They select an unknown tree in their neighborhood that they will be able to re-visit throughout the school year.  In their first visit, they provide labeled illustrations and written descriptions of the whole tree and parts of the tree (leaf, bark, flowers, seeds, twigs, etc).  Students describe the color, shape, size, textures of their tree.  Students also describe the environment of their tree:  biotic and abiotic conditions.  Students share their projects and we compare the types/degree of detail of the characteristics they focused on. We discuss the difference between observations and inferences.  The class projects serve as a preliminary sample of  the variety of trees that exist in New York City.  

After completing this workshop, I will also have my students learn about their tree from a micro-biological perspective.  

• Winogradsky Column:  Students will collect a soil sample from their tree and use plastic Poland spring water bottles to make a Winogradsky column.  They will be able to make ongoing observations of the diversity of bacteria.  They can also experiment with different nutrient mediums, such as hard boiled egg yolks compared to egg whites.  In addition, it's a fun way to learn about the scientific method. 

• Berlese Funnel Method:  Students will also collect leaf litter samples from their tree and use Poland spring bottles to make the Berlese Funnel.  Students will make observations of the diversity of cryptozoa in their samples.

REFLECTION

I really enjoyed having the opportunity to participate in this institute and work with so many professional researchers and educators.  It was wonderful to learn new techniques and paradigms of thought in microbiology and macro-biology.  It is incredibly important for teachers to have these experiences so that they can transfer their knowledge and enthusiasm to their students.  I look forward to applying what I learned at the Institute to my classroom this year!
