The first semester of Summer School Biology is almost complete. Your final will occur on Thursday, June 30th. You will receive a study guide for the final in Wednesday's class, as well as a final Lecture Guide based on "Discovering DNA!"

The most important goal all students should focus on, however, is making sure that their composition books contain all of the course notes, complete Cornell Note-taking style, as this constitutes 50 percent of your grade!

Toward that end....

The Power Point summarizing the Cell Cycle, based on Monday's lecture, is available here:

The notes from Tuesday and Wednesday's lectures, on which the final Lecture Guide is based, are given below:

These Power Point notes are available for download here.

The latest 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.


The Lecture Guide on "Cellular Respiration" is due on Monday, June 27th. In the last three days we will be covering a great deal of material: cell division, phases of mitosis/meiosis, DNA structure and function, and an outline of transcription and translation.

FIFTY PERCENT of your course grade is based on your Cornell Notes, which must be submitted after the break on Thursday, June 30th, no exceptions. There will also be a FINAL EXAM on that day. You will receive a study guide from your instructor on Wednesday. Obviously, the pressure is on. You have to maintain your focus in order to complete all this work by the end of class on Thursday!!

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 at the beginning of Thursday's class! We are now halfway through the first semester of summer school!!

You can get the Power Point for 'The Fluid Mosaic Model of the Cell Membrane" here. There are drawings in Chapter 7 of your text, particularly the one on pg. 182, that would be good for students to have completed in their notes. Mr. Hatfield, as always, recommends that students use colored pencils to complete their drawings in their Cornell Notes.

Here is the Power Point on 'The Chemistry of Life.' Students received a Lecture Guide based on these notes, given on Thursday, June 16th. This Lecture Guide and the worksheet on the video "The Lives of the Stars" are due on Monday, June 20th. Students should also use that Guide to compare the notes in their composition books with the Power Point notes, to make certain that they have all the content mandated by the state standards.

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


The following episode of Carl Sagan's Cosmos, 'The Lives of the Stars', forms the basis of a student homework assignment. Click on the icon below to play the video within the blog:

Students! Here is the Power Point for the notes on 'The Nature of Science'. Your Lecture Guide, given out in class today (Tuesday, June 14th), is due at the beginning of Wednesday's class.

It is YOUR responsibility to complete your Cornell Notes, which are 50 percent of your grade in this course. Due to the large amounts of material that must be covered in a Summer School course, we must move at an accelerated pace. Therefore, when you complete the Lecture Guide, compare the Guide with your Notes. If there are any missing items in either the Lecture Guide or the Note, use the Power Point shown above to fill in the gaps.

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!

It is your responsibility to gain access to this material. Students who are unable to upload the Power Points should contact the instructor immediately via email:


I can either email Power Points to students, or students may bring in a flash drive and I will copy it onto their drives....but it is the student's responsibility to gain access to the material.

Here's a novel thought: instead of being taught as mindless, slavish dogma, evolutionary biologists have been busy in the last 150 years. They've been testing, retesting, modifying and in some cases rejecting aspects of Darwin's theory. This Power Point explains some of the major innovations, which (by the way) are all in the textbook:

Students who need to download the Power Point to complete their notes, and the Lecture Guide based on it, can do so here.

We've just finished these notes, and many of these ideas are important in some of the potential essay topics that students should already be working on, so those students especially will want to get up to speed. Students will receive a Lecture Guide based upon these notes TODAY!

ALSO....There is a Study Session on Saturday for the FINAL, in Room N-63, between 1:00 - 4:00 PM. Students can earn extra credit in the course and receive helpful hints on how to proceed. Attendance is voluntary.
