Test Today

Today in Class: Exam. No homework, Have a nice four-day weekend.

August 25, 2008—New Species discovered. The Atlantic goliath grouper, found in warm waters of the Americas and western Africa, is a separate species from the goliath grouper that roams tropical reefs of the eastern Pacific Ocean, a new genetic study shows.


The newly identified Pacific goliath grouper can grow more than 6 feet (1.8 meters) long and weighs nearly 1,000 pounds (454 kilograms).

"For more than a century, ichthyologists have thought that Pacific and Atlantic goliath groupers were the same species, and the argument was settled before the widespread use of genetic techniques," Matthew Craig of the Hawaii Institute of Marine Biology said in a statement. Follow the link below to read the whole story.

State Standard: S2C1PO1 Describe how human curiosity have influenced science.

(Wednesday, Aug 27) -Study for Test

Carcasses of Southern Yellow-legged Frogs in Sixty Lake Basin in Sierra Nevada, California. The frogs died of chytridiomycosis, an amphibian disease caused by a particularly virulent fungus.



Today in Class: Finish Cornell notes on "Characteristics of Life", glue upside down triangle graphic organizer into Interactive Packets. Read book pgs 17 - 21. Analyze Powerpoint pictures to determine if they are, or were, living. Study for Test


Homework: 2-sided Stimulus and Response sentences and pictures.

Is it alive?

Is it Alive? Lab





Cork Trees found in the Mediterranean have extra thick bark that is stripped off and used for commercial products.


Today in Class: We investigated 20 objects to determine if they are alive, or were alive, or never were alive. We know that living things have levels of organization and we worked on a poster to define the organization levels and place them in the correct order.


State Standard: S4C5PO5 Describe the levels of organization of living things from cells, tissues, organs, organ systems organisms, populations, communities and ecosystems. Follow the link below for an excellent tutorial on Organization Levels.


Life's Levels of Organization

Traits of Life

What Concept is shown in the camouflaged moth?




Today in Class: Cornell Notes on Traits of Life, Is it alive? How do living things adapt to survive in their environment? Video on "What is Life?". What is the difference between prokaryotes and eukaryotes? What is the difference between growth and development? Ask your student about Pavlov's dog.


State Standard: S4C5 Matter, Energy, and Organization in Living Systems (Including Human Systems) Understand the organization of living systems, and the role of energy within those systems.


Answer: Mimicry is the resemblance of one organism to another or to an object in its surroundings for concealment and protection from predators.

Viruses

Today in Class: Friday Quiz about lab safety and microscope lab. Introduction to Viruses and diseases caused by them. Textbook pages 478 - 484 and a powerpoint presentation will help clarify any misconceptions.



Smallpox Victim shown below.



Smallpox Virus: Smallpox was a devastating scourge. It was a highly contagious viral disease that killed up to half of those infected and seriously maimed survivors, through severe scarring of the skin with deep pock marks, blindness and infertility. However, those who did survive enjoyed protective immunity from further infection for the rest of their lives.


Homework: Individual grade sheets need to be signed by a parent and returned MONDAY.


State Standard: S4C2PO2 Describe the molecular basis of heredity, in viruses and living things, including DNA replication.

Microscope Lab


Today in Class: Microscope labeling and lab. Students looked at prepared slides and then learned how to make their own. They identified several types of pond critters on various levels of magnification. Pictured below is a pond critter Michael watched for 30 minutes.


Homework: "Study of Life" puzzle. There are 20 vocabulary words that are on the puzzle. Be sure to look at your cheat sheet for the definitions!


State Standard: S1C2PO2 - Identify resources needed to conduct an investigation.

Course Description This course is an introductory class into Living Systems, Environment and the process of science. Biology is designed to address Arizona State Standards 1 and 4 for Life Sciences. Major areas of focus will include: cell structure and function, genetics, heredity, body systems, classification, natural selection, variation within a species, and the interactions of all levels of biology in terms of world and regional ecology.

Graduation Fulfillment Passing this course earns you one credit towards your high school graduation and fulfills a lab science requirement for college entrance.

Grading Grades will be determined by the total points possible. There is no extra credit. Late homework will not be accepted. See page 18 of the student handbook for make-up work for excused absences.
A = 90 – 100 %
B = 80 – 89.9 %
C = 70 – 79.9 %
D = 60 – 69.9 %
F = Below 60 %
20% Tests
20% Friday Quiz
20% Homework
40% Classwork, labs,
and notebook

Attendance:
Be in class. Be on time. There is a school wide 5-absence “Audit” rule. This means you will be audited after five absences. School activities do not count as an absence. Excused absences will count toward the 5-absence rule.

Classwork:
Students will use the Cornell note-taking system in Biology. They should use a pencil for notes and labs. They will have a quiz every Friday, and a 6 unit tests. Students will be allowed to create a 3 x 5 note card with formulas or information as a “cheat sheet” for tests (except the AIMS).

Movies:
Most movies shown in Biology are unrated because they are produced for science classes. I will be showing several IMAX videos (G-Rated) and one PG movie “Osmosis Jones”.

Discipline Plan:
I prefer to handle discipline in my own classroom, using humor and positive reinforcement. Since this is a science class I expect students to practice lab safety and will immediately dismiss a student from a lab if they do not adhere to the safety rules. I value respect and will model this quality for your students. I expect the same from them. My discipline plan uses a three-dimensional approach suggested by Curwin and Mendler.

Prevention: What can be done to minimize problems.
Action: What is to be done once problems occur.
Resolution: What can be done for the chronic misbehavior.

If a student causes classroom disruptions they will be offered a choice, to stop the behavior or choose a consequence related to their behavior. For chronic offenders I will assign the student a detention and a written referral, which will result in a parent contact. This consequence is typically given after all other methods have failed.

My goal with students is to promote responsibility for their actions and help them develop long-term control over the course their life takes.

Bathroom Pass:
Students are expected to take care of personal needs on their own time. Students receive two 10-point bonus slips at the beginning of the semester. The bonus slips may be used as a free-pass for a homework assignment or surrendered if used to leave class for personal needs.

Electronics:
See page 22 of the Student Handbook. If you need to contact your child immediately I would suggest going through the office.

Online:
There are many good websites related to Biology. I encourage you to look at them with your students. Some of my favorites are “Science Spot”, “How Stuff Works”, and “Biology Junction”. Even YouTube has some excellent tutorials on science topics.

Thanks for supporting me in my endeavor to teach your child. I appreciate the opportunity to get to know them; they are great kids with lots of energy and enthusiasm!
