POWER POINT: "DARWIN'S DANGEROUS IDEA!"

Here's the Lecture Notes.

Here's a PDF file of the Lecture Guide based upon the notes.

The title, incidentally, is taken from the Daniel Dennett book which also inspired a two-hour episode of the NOVA 'Evolution' series. We will end up seeing much of this episode, broken up into chunks, over the next few weeks, so I thought I would provide a link to view the whole thing on-line, here.

BIOLOGY POWER POINT: "DEEP TIME!"

The Power Point Lecture Notes on 'Deep Time' are available here.

Students who were absent on Thursday and/or Friday's class before Spring Break almost certainly are missing part of these notes. Mr. Hatfield will review the final slides with students in class on Tuesday, and make sure that they have the Lecture Guide based upon these notes.....


FACT: The fossil record (and other lines of evidence) show us that populations of living things have "changed over time" (evolved)....

QUESTION: How can we explain this pattern of change in terms of NATURAL causes?

BIOLOGY: DIVERSITY AND CLASSIFICATION

These notes were given to students on March 15th-March 20th. The Power Point on "Diversity and Classification" can be uploaded here. The Lecture Guide based on the Power Point can be found as a PDF file here.

BIOLOGY POWER POINT: INTRODUCTION TO BIOTECHNOLOGY

The Power Point with the Notes on Biotechnology is available here. All students will need to download the entire Power Point in order to finish the Lecture Guide, so make sure you do it!

Students who have lost their original Lecture Guide and need to get another copy can download the Guide as a PDF file here.

The Genetic Disorders Poster Project was due today.

We will do a Lab in class tomorrow. Students may need to complete their notes outside of class by using the Power Point if they miss one or more sessions of class due to CAHSEE. There is a Study Session after school on Wednesday between 3:15 and 5:15, and the Unit Test will occur on Friday, March 16th.

BIOLOGY POWER POINT: HUMAN HEREDITY

*****NOTE: POST REVISED*****

The Power Point Notes for Human Heredity are available here.

STUDENTS: Please remember that you have a major 100-point project DUE on Tuesday, March 13th. This is a GROUP project. Next Monday (the 12th) is the ONLY in-class work day you will be given for the poster project, so you and your group need to meet beforehand.





The STUDY SESSION for the next Unit Test is after-school on Wednesday, March 14th. The next Unit Test is Thursday, March 15th.

"CRACKING THE CODE OF LIFE"

Here's a link to our recent notes on 'Mutation!'

A PDF of the Lecture Guide based upon the Power Point is available here.

The video viewed in class, and thus the handout based on it, can be viewed on-line here:



There is an entire PBS-sponsored web site to accompany this program. It's truly excellent, and since I can't show the entire program within a regular class. I can, however, assign a segment of it along with Section 14.3 of our text to help students understand the material and complete the worksheet. So, read that section, watch video segments 4-8 and complete your work, students!

POWER POINT: PROBABILITY AND GENETICS

The lecture notes for the present unit on Genetics is available at this link. Students have been assigned a 70-point Project, a "Mendelian Genetics" booklet. They may find the notes, as well as their text (Chapter 11) are very helpful in completing this project, which is due on Friday, Feb. 3rd. They have also received a Lecture Guide in Mendelian Genetics that covers this material, which will be due on Monday.

Students who fail to hand in their BOOKLET by Monday, Feb. 6th, may have the home contacted.

POWER POINT: PROBABILITY!

Here is the (brief) Power Point discussing, and giving examples of some basic principles of probability. This is, of course, math....but an essential tool, also, for doing science.

PLEASE NOTE: BOTH MY BIOLOGY AND ENVIRONMENTAL SCIENCE CLASSES SHOULD HAVE THESE NOTES!!

BIOLOGY FINALS WEEK: PROJECT, STUDY SESSION, EXAM SCHEDULES, NOTES

Parents and Students:

Monday (Dec. 12th) began the final week of instruction for the Fall Semester. This is a post to give everybody one last 'heads-up' about Finals week in Biology!

First of all, 'A Twist of Fate', an important 100-point project, is due on Friday (12/16), and no late work of any kind will be accepted after Monday (12/19)

This assignment is based on a reading describing the scientific detective story that led to the discovery of DNA's structure. The reading is adapted from an article by Michael Lemonick that appeared in the Feb. 17, 2003 issue of Time. That article can be read in its entirety on-line here.

Students are expected to define terms underlined in the article, and to answer four discussion questions according to the usual guidelines: complete sentences that refer to the original question and provide supporting evidence for the student's opinion.

Secondly, students will receive a Study Guide for their 200-point Semester Final on Friday (12/16)

Students should be reviewing it and using it to identify any weaknesses, as well as working to submit any other outstanding work in the course by the end of instruction (Monday, 12/19).

Next, there will be a Study Session after-school on MONDAY (12/19).

This Study Session will take place in my classroom (N-63). It will begin at 3:15 and end at 5:30 that evening. Students who attend will not only receive valuable feedback as to what to expect on the test, but will also receive up to 40 points of extra-credit.

And, finally...Finals! Our scheduled Finals are on (12/20) Tuesday for 4th period, (12/21) Wednesday afternoon for 5th and 6th period.

There is no significant makeup period, as the above schedule shows. Students need to attend their final exam period if they want significant time for their Final. Those who fail to attend without having their parent or guardian reach a prior understanding with Mr. Hatfield will be given an 'incomplete' in the course.


Finally, the Power Point with notes on DNA and Protein Synthesis is available on-line here:


The Power Point notes are available for download here.

A PDF of the Lecture Guide based on the Power Point notes is available here.

BIOLOGY: POWER POINTS FROM NOVEMBER

In November, our Biology classes covered material on how cells obtain, store and release energy. During that time, there were several groups of notes of various sizes for students to access.

First, this Power Point (previously given) contains an outline of photosynthesis, relating it to the 'Great Circle' of chemical reactions that all living things participate it (autotrophs and heterotrophs!), reactions which recycle the raw materials that life requires. Much of this material is covered in the first two sections of Chapter 8 in the Dragonfly Book.




The Power Point for Photosynthesis, Part I, is available here.

Photosynthesis, Part II provides much more detail about the light reactions, photosystems, the proton pumps that use the enzyme ATP synthase, the electron transport chains that help power those pumps. There is less detail about the 'dark reactions' of the Calvin cycle and other material which is not explicitly part of the state standards. This is covered in Section 8.3 of the Dragonfly Book.

You can download Photosynthesis, Part II here.

A third Power Point is somewhat brief, but has many helpful animations that help describe and explain the structure and function of ATP (adenosine triphosphate), the main energy-carrying molecule used by living things.

The fourth and final Power Point in this unit contains information about cellular respiration, including glycolysis (which takes place in the cytoplasm) and the Krebs Cycle (which takes place in the matrix of the mitochondria). The electrons produced in the Krebs Cycle move through the inner membrane, or cristae, of the mitochondria. The motion of these negatively-charged particles attracts protons (H+), and eventually a high concentration of protons within the membrane is available to drive 'proton pumps' that power an enzyme, ATP synthase, leading to the production of more ATP:





You can download the Power Point for Cellular Respiration here.

HOUSEKEEPING:

SATURDAY SCHOOL was held on Dec. 3rd, in Room N-63, between 8:45 and 11:30. Students who attended received a packet of illustrations to color and label based on materials from chapters 7-9 (cell membrane, transport, animal and plant cells, photosynthesis) as well as a diagram on DNA.

Students also received (in advance) the Final Project for the fall semester, a handout called "A Twist of Fate" based on an article that appeared in TIME magazine to celebrate the 50th anniversary of the discovery of DNA's structure. The original article can be viewed on-line here; the text has been modified to emphasize vocabulary development and will challenge students to analyze a test case of science as actually practiced by real men and women.

BIOLOGY POWER POINT #11: PHOTOSYNTHESIS, PART 1

This Power Point contains an outline of photosynthesis, relating it to the 'Great Circle' of chemical reactions that all living things participate it (autotrophs and heterotrophs!), reactions which recycle the raw materials that life requires. Much of this material is covered in the first two sections of Chapter 8 in the Dragonfly Book.

The Power Point for Photosynthesis, Part I, is available here.

A PDF file of the Lecture Guide based on that Power Point can be downloaded here.

The Lecture Guide based on these notes is due MONDAY, November 28th!

BIOLOGY POWER POINT #10: THE CELL CYCLE

The Power Point summarizing the Cell Cycle, based on the first two sections of Chapter 10, is available here:

BIOLOGY POWER POINT #9: THE FLUID MOSAIC MODEL OF THE CELL MEMBRANE

For students who still need to complete the previous Unit notes, please look at the previous post on 'Cells and Their Organelles" as well as this one. CLICK ON THE IMAGE IF YOU NEED THESE NOTES!


POWER POINT: THE FLUID MOSAIC MODEL OF THE CELL MEMBRANE

BIOLOGY POWER POINT #8: CELLS AND THEIR ORGANELLES

Here's the link you need to download this Power Point, to use to complete your notes or the Lecture Guide based upon it.

BIOLOGY POWER POINT #7: "CARBON THE BASIS OF LIFE"

SPACE

This Power Point is available to download here.

BIOLOGY POWER POINT #6: THE CHEMISTRY OF LIFE

Here is the Power Point on 'The Chemistry of Life.' Students will receive a Lecture Guide based on this Power Point in Monday's class.

BIOLOGY POWER POINT #5: ACIDS AND BASES

HEY!

Here is the link to the Power Point on acids, bases and the pH scale.

BIOLOGY POWER POINT #3: ATOMS AND MOLECULES

. UPDATE: We are now in Unit #2. A new syllabus should be available both as a handout and on-line by the end of this week.

In the meantime, students, in case you haven't completed this item, for all my classes, here are the notes on 'Atoms and Molecules.'

****UPDATE****

POWER POINT NOTES: THE NATURE OF SCIENCE

Students! Here is the Power Point for the notes on 'The Nature of Science'. You will receive a Lecture Guide based on these Notes sometime this week! If you don't have Power Point on your computer, don't worry . . . you can download a free program, Power Point Viewer, to see the notes!

KEEP IN MIND...this year, in Mr. Hatfield's Classes, we will try to reduce the amount of class time spent taking notes. There are dozens of standards to cover, hundreds of vocabulary terms and other items to master. We need to decrease the amount of time spent in lecture so students can have more time to do activities. Remember: we want to engage as many different parts of the brain as possible, and to do that, we need to have more time to do things other than notes.

At the same time, your Cornell Notes must be complete (all the notes, original questions and comments in the margins, your name/date/course on every page, and summaries of major sections of notes). Therefore, it is the student's responsibility to download and complete any notes that they were not able to finish in class!!

THE NATURE OF SCIENCE

POWER POINT NOTES: INTRODUCTION TO MR. HATFIELD'S COURSE

Click on the image above to take you to a Power Point that contains information about Rules, Policies, Procedures, and other classroom policies in Mr. Hatfield's classes. This will also contain Mr. Hatfield's outline of the features of Cornell Notes, a major part of this course.

If you do not have Microsoft Office, don't worry, you can still view the Power Point Notes...for free! Simply download Power Point Viewer, a free program of modest size (about 60 MB).

It is vital that you have access to a program that can view Power Points. Lecture in Mr. Hatfield's course will proceed at a brisk pace, and most students will only write down "skeleton notes"....an incomplete outline of the full presentation. Students will need to download the Power Points to complete the full lecture, and they will need to complete the note-taking before they embark upon completing the extended question margins and the summaries of major sections which are key parts of the Cornell Note-taking strategy.
