Absorption, Digestion, and Exchange

Brewer Middle School - Greenwood, South Carolina

7^th Grade Science - Mr. Dan Hodge 

Expected Unit Outcome:

The student will demonstrate an understanding of the functions and interconnections of the major human body systems, including the breakdown in structure or function that disease causes. (SC Science Academic Standard 7-3) 

Expected Student Proficiencies (from SC Science Academic Standards):

1. Summarize the levels of structural organization within the human body (including cells, tissues, organs, and systems).
2. Recall the major organs of the human body and their function within their particular body system.
3. Summarize the relationships of the major body systems (including the circulatory, respiratory, digestive, excretory, nervous, muscular, and skeletal systems).
4. Explain the effects of disease on the major organs and body systems (including infectious diseases such as colds and flu, AIDS, and athlete’s foot and noninfectious diseases such as diabetes, Parkinson’s, and skin cancer).

Layered Curriculum® Notes:

1. I expect students to be working on this unit at all times while in the classroom.  Not working will result in a lower grade.  Other misbehavior will be handled with the goal of returning the student to his work as soon as possible.
2. Any question and answer work from the textbook or PACT Coach Book should be written out in full.  No credit will be given for partial work.
3. Use the checklist to keep track of your work.  Cornell Notes (CN) should be given to Mr. Hodge as soon as you complete the three sections.  You will answer questions from your Cornell Notes as part of your Oral Defense.
4. MAKE UP WORK:  All work is printed and put into folders in the red folder organizer by the door (C Layer = Yellow, B Layer = Green, A Layer = Blue).  If you are absent, you may pick up any worksheets you need from the organizer. 
5. DO NOT FALL BEHIND!  It becomes very hard to catch up.  See Mr. Hodge if you need assistance.

General Instructions:

1. Items that are “hearted” (Y) are required.

3. You must complete one layer before moving to another.  No more than 4 assignments may be signed off by Mr. Hodge on any one day, in any layer.  Each assignment has a point value based on the amount of time and effort necessary to complete that task. 
4. You must earn the required number of points in one layer before moving to the next.  Students are expected to work on every layer.
5. There will be a study guide and test at the end of the unit.
