We continued our chemistry block last week with a look into the limestone cycle of the earth. We explored how the ancient carbonate limestone is heated to form quicklime and then hydrated to slaked lime and how that cycle has been significant to humanity in building and agricultural applications since ancient times and still today. We also studied the biography of Marie Curie and her contributions to science and humankind through her work in chemistry and physics. We explored the building blocks of matter from the atomic particle level to the molecular level and the history of those discoveries. We will continue next week learning about the crystallization process and acids and bases.

In math, we continued working with triangles in the Key to Geometry series. Additionally, we worked with Pythagorean triples, the golden ratio, and we derived phi from the Fibonacci sequence. It was a busy but fun week!

We are winding down our "40 Book Challenge" and most of the students are hovering right around the goal. The book challenge is not intended as a competition but rather a personal challenge for each student. My goal was to increase interest, stretch them, and boost their motivation and reading competence. Regardless of our final tally, I'm confident we've achieved that goal! We've read some incredible stories this year. Have them share their book list with you and tell you about some of their favorites!

Please join us this Friday if you are able. We are looking forward to seeing you on Friday evening to preview all the wonderful items that will be auctioned. You can purchase your tickets here to pick a time slot. All participants, whether joining us in person or online, will require a ticket to bid! Bidding starts Friday at 5:30 PM and ends Saturday at 12:00 PM. The proceeds benefit our school and therefore our entire school community. Your participation in our first annual school auction is boundlessly appreciated!
