7th, 8th, and 9th Grade. For this week only, all students are studying the human respiratory and circulatory system. For the 7th and 8th graders, this will serve as an introduction to our Chemistry of Food and Respiration Unit. For the 9th graders, this is the last week studying the human body. Monday we will begin our Evolution unit.

October 9 Homework. As we have been moving slower than anticipated the "Section 37-1: The Circulatory System" Worksheet will be due on Monday, October 13 (it was originally due tomorrow, October 10).
