The Arnold Arboretum of Harvard University is a community resource for education. During the 2022-2023 school year, Arboretum for Educators will take the form of a newsletter highlighting hands-on science lessons and activities that get students outside using their local outdoor classroom, playground, or campus. Many of the lessons can also be conducted by bringing the outside in!

Each month will have a seasonally based theme with a key activity for students in PreK-2, Grades 3-5, Middle School, and High School according to schedule below.

Upcoming Newsletters:

  • October: What is a Leaf? Investigate leaf structure through rubbings, chromatography, water experiments and decay.
  • November: What is a Seed? Discover dispersal strategies and engineer better seed packages.
  • December: What is a Tree? Part 1 Learn about tree architecture, twig identification, and nature journaling.
  • January: What is a Tree? Part 2 Understand phloem and xylem, create models of the inside of trees, and have fun with outer bark.
