Harvard Forest Schoolyard Ecology Data Analysis Workshop 2016

Compilation of teacher-developed graphs and data documents from the Harvard Forest Schoolyard Ecology Workshop 2016. The documents include comparisons of tree species by plot, number of tree species, carbon biomass, and biomass distribution across different species and plots. Additionally, the analysis includes air temperature trends at various ponds over seven years. The data was compiled and presented by various teachers and mentors involved in the workshop.

9. Graph 8 : Growing Season At Trinity Catholic Academy 2014-2016 Description of graph: Bar graph of length of growing season at Trinity Catholic Academy over three years. X Axis: Tree ID Number Y Axis: Number of Days Teacher/Author: Colleen Casey Lori Primavera School: Trinity Catholic Academy Grade Level:4th and 5th Educational Objectives: Our students are studying the bud burst and leaf fall of 5 trees here on our campus. Here is three years of our data to show the change in our growing season which is the time when the tree is photosynthesizing.

10. Graph 9 : Timing of Budburst from 2014 to 2016 Thisbar graph illustrates the average time of spring bud burst over the last 3 years. Bar colors represent different years. Description of graph: X Axis: Tree ID Number Y Axis: Date Teacher/Author: Colleen Casey Lori Primavera School: Trinity Catholic Academy Grade Level:4th and 5th Educational Objectives: Our students are studying the bud burst and leaf fall of 5 trees here on our campus. Here is three years of our data to show the change in timing of buds opening in Spring.

11. Graph 10 : Timing of Leaf Drop from 2013 to 2016 This bar graph reflects the average date in which the leaves fell for each year. Description of graph: X Axis: Tree ID Number Y Axis: Date Teacher/Author: Colleen Casey Lori Primavera School: Trinity Catholic Academy Grade Level:4th and 5th Educational Objectives: Our Students are collecting data from 5 tress located on the grounds of Trinity Catholic Academy. This graph helps students see what the data is showing for the timing of leaf fall at our school.

Teacher/Author: Louise Levy School: Belchertown High School Grade Level: 11,12 Educational Objectives: In conjunction with field site visits and characterization, students will assess any differences between the leaf drop of two same-species trees and posit the causes for those differences.

13. Graph 12 : Timing of Red Oak Leaf Fall Compared Across 2 Field Sites at Belchertown High School Description of graph: Line Graph comparing Red Oak leaf drop at 2 study sites at Belchertown High School. Teacher/Author: Louise Levy School: Belchertown High School Grade Level: 11, 12 Educational Objectives: In conjunction with field site visits and characterization, students will assess any differences between the leaf drop of two same-species trees and posit the causes for those differences.
