Cells and Heredity

Brewer Middle School - Greenwood, South Carolina

7^th Grade Science - Mr. Dan Hodge 

Expected Unit Outcome:

The student will demonstrate an understanding of the structure and function of cells, cellular respiration, and heredity. (SC Science Academic Standard 7-2) 

Expected Student Proficiencies (from SC Science Academic Standards):

1. The student will be able to summarize the structures and functions of the major components of plant and animal cells (including the cell wall, the cell membrane, the nucleus, chloroplasts, mitochondria, and vacuoles).
2. The student will be able to compare the major components of plant and animal cells.
3. The student will be able to compare the body shapes of bacteria (spiral, coccus, and bacillus) and the body structures that protists (euglena, paramecium, and amoeba) use for food gathering and locomotion.
4. The student will be able to explain how cellular processes (including respiration, photosynthesis in plants, mitosis, and waste elimination) are essential to the survival of the organism.
5. The student will be able to summarize how genetic information is passed from parent to offspring by using the terms genes, chromosomes, inherited traits, genotype, phenotype, dominant traits, and recessive traits.
6. The student will be able to use Punnet squares to predict inherited monohybrid traits.
7. The student will be able to distinguish between inherited traits and those acquired from environmental factors.

 

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.
4. MAKE UP WORK:  All work is printed and put into folders in the red folder organizer by the door.  If you are absent, you may pick up any worksheets you need from the organizer. 
5. There are two deadlines for work to be turned in.  The first is the report card deadline, Wednesday, January 9^th, 2008.  The second is the completion of the unit, Tuesday, February 5, 2008.  No more work will be accepted on this unit after these dates.
6. DO NOT FALL BEHIND!  It becomes very hard to catch up.  See Mr. Hodge if you need assistance.

General Instructions: 

1. Items that are starred (µ) are required.
2. All reading activities (from textbook and PACT Coach) will require an oral defense.  You will be awarded your points only after you answer questions from Mr. Hodge about what you have learned.  You may work with partners, but you must be able to answer the teacher’s questions without any help.
3. You must complete one layer before moving to another.  No more than 3 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.  You must earn the required number of points in one layer before moving to the next.
4. Students are expected to work on every layer.
5. At the end of the unit, assemble all your work in a folder, and be prepared for your oral defense of learning.  Mr. Hodge will interview you on your learning, and you will need to be prepared to give a brief report of what you have learned.
6. There will be a review and test at the end of the unit.
