“The earth’s vegetation is a part of the web of life in which there are intimate and essential relations between plants and the earth, between plants and other plants, between plants and animals, and we must learn to respect that fine and fragile web if there is to be anything left for the next generation.” -Rachel Carson
We had a wonderful week! We enjoyed the gorgeous fall weather with outdoor biology work and Lit Circle. We were also thrilled to welcome a new friend to our class this week!
In our biology lesson this week, we learned that cell membranes are built using nitrogen, an element that makes up 78 percent of the air around us. We discussed how nitrogen needs to be “fixed” in partnership with other atoms for cell building. We also talked about the first nitrogen-fixing process that took place during the creation of the universe, where nitrogen atoms were forced into partnerships with other atoms by thunderstorms and volcanoes. This made them available for making cells. We also learned about the nitrogen cycle and the role of bacteria and fungi. Additionally, we learned that legume roots, in partnership with bacteria, play an essential role in fixing nitrogen. As part of our follow-up work, we dug up some clovers, keeping their roots intact to take a closer look.
Our geometry lessons are taught in two groups. One group learned about six different polygons and the parts of a polygon. The other group learned about finding the area of a rhombus.
In history, we learned about the Cro-Magnon people, who lived between 40,000 and 30,000 years ago. We looked at how they were like the Neanderthals: they lived in caves, buried their dead, and made clothes. We also learned that they did something that no earlier humans had done: they created works of art through paintings, sculptures, carved designs, and ornaments. As a follow-up activity, Sara introduced the children to a 35,000-year-old Cro-Magnon form of art called hand stencils. These works of art were painted in caves in France, Indonesia, and Australia. We will continue to work on cave art outside our classroom next week.
