“Trees are poems that the Earth writes upon the sky.” –from “Sand and Foam” by Kahlil Gibran
We enjoyed an active week in Upper El. Highlights included gardening, an Arbor Day presentation, and new math, geometry, and chemistry lessons.
Students began the week moving the raised bed flowers to pots in preparation for relocating those beds during the field construction. As is typical of these students, they tackled the project with joy and enthusiasm. We are hopeful the plants will survive the move, and we can replant them in the fall when the field is complete.
We had a visit from Charlie Arrindell, who gave a captivating presentation about the benefits and anatomy of trees and Arbor Day. He gifted each of us a sapling to plant at our homes. Thank you for sharing your time, generosity, and knowledge with us, Charlie!
In geometry this week, fourth graders learned to find the area of a parallelogram and discovered they use the same formula they used to find the area of a rectangle. Fifth graders learned about the concept of the circle as the limit of regular polygons. They researched this with Montessori insets of each plane figure, three through ten sides, and a circle and learned that each “side” of a circle is a point on the curved line that forms the circle’s circumference. They identified the circle as the “ultimate polygon.” Their follow-up work was to translate the nomenclature of regular polygons into the nomenclature of the circle. Fifth graders also prepared for next week’s lesson by beginning a study of the apothem of each figure, triangle through decagon. They drew each figure and traced their apothem, radius, and base.
This week in chemistry, we learned about the sun’s nomenclature and discovered some amazing facts about its distance from Earth, temperature, size, mass, gravity, age, and core reactions.
We are still waiting to hear back from the bus company on their cost for our trip to Nature’s Classroom. I will email you your final cost as soon as they confirm.
Wishing you a lovely weekend,
