Test coming up - 10/30 (a-day) and 10/27 (b-day)

Study AGS Chapter 1 as well as all the notes and activities we've done in our Interactive Biology Notebooks (IBN's.)

Part of your studying involves reviewing Chapter 1 from AGS. You need to turn in the Chapter 1 Review (Pp. 27-29). Answer all 25 questions and be sure to write all questions and write out all answers. Answer the critical thinking questions in full sentences. Due Thurs. 10-22 (b-day) and 10-26 (a-day). If you don't know any answers FIND THEM IN THE BOOK - most are "right there" questions or "think and search" type questions.

Use the review sheet you received in class to make sure you are studying all the topics. This test will be CLOSED notes so you need to memorize important terms and be sure you UNDERSTAND the ideas we've discussed them so you can apply them.

In case you don't have your review sheet, here is the info from it.

Plant Growth Data - for those who didn't finish their graph in class

Here is the plant growth data we were graphing in class.

Plant-----Week one------ Week two------ Week three ------Week four

A ---------10.5 cm ---------10.3 cm ---------10.0 cm --------- 9.5 cm

B -------- 10.9 cm ----------11.5 cm ---------12.3 cm ---------12.5 cm

C -------- 11.0 cm ----------11.5 cm ---------12.5 cm ---------13.5 cm

When you do your graph be sure to label the X and Y axis with the variable and units. Also create a title which includes both variables in the experiment. For example, "How_____ affects _______."
