__** Wed 8/30 **__ (early release) observe bananas & record observations (baseline data) This lesson is designed to reinforce the students understanding of physical & chemical changes. Students are to read and take notes using pages 48-49 (complete section review questions on page 49); Pages 50- 55 (section review on page 55); 388- top section of page 390;

HOMEWORK: finish today's class assignment, if you did not complete it in class.
