A.P. Biology Summer 2003 The Advanced Placement Biology course is designed to be the equivalent of a college introductory biology course usually taken by biology majors during their first year. The AP Biology course is designed to be taken by students after the successful completion of a first course in high school biology and one in high school chemistry. (Usually with grades of "B" or better and who are possibly contemplating a major in a science related field. All students are strongly encouraged to take the A.P exam) The overall success of the A.P. program depends, in a large part, on students meeting their individual responsibilities. A significant portion of the content of this course will be covered independently by each student. To many AP Biology is considered the most difficult of the AP Science courses. Your grade will probably be closer to your chemistry grade than your Biology grade. You might expect a letter grade lower than your chemistry grade. There are many variables but it is a difficult class. I am not trying to scare you because you can be successful if you want to, but you need to know the class will require a lot of effort. Allowances should be made for substantial study time. Some studies have shown seven to ten hours per week outside of class is necessary to be really successful. After showing themselves to be qualified on the Advanced Placement Examination, some students, as college freshmen, are permitted to take upper-level courses in biology or register for courses for which biology is a prerequisite. Other students may have fulfilled a basic requirement for a laboratory science course and will be able to take other courses to pursue their major. Each college makes its own determination of what is a qualified score. The two main goals of AP Biology are to help students develop a conceptual framework for modern biology and to help students gain an appreciation of science as a process. The ongoing information explosion in biology makes these goals even more challenging. Primary emphasis in an Advanced Placement Biology course should be on developing an understanding of concepts rather than on just memorizing terms and technical details.(But memory is also important). Essential to this conceptual understanding are the following: · a grasp of science as a process rather than as an accumulation of facts; · personal experience in scientific inquiry; · recognition of unifying themes that integrate the major topics of biology; and · application of biological knowledge and critical thinking to environmental and social concerns. There are eight major themes that recur throughout the course. AP Biology will emphasize these themes and assist you in organizing concepts and topics into a coherent conceptual framework: 1. Science as a Process 2. Evolution 3. Energy Transfer 4. Continuity and Change 5. Relationship of Structure to Function 6. Regulation 7. Interdependence in Nature 8. Science, Technology, and Society Expectations: 1. A record of excellent attendance. Since this will be a MUCH faster paced course than a normal high school course, missing class will be a huge disadvantage. Because of the nature of this course, any time you miss must be made up in an equivalent fashion. You are responsible for any material missed. 2. Make certain that all assignments, reports, and evaluations are completed on time. If there are extenuating circumstances preventing your completion talk with me BEFORE the due date. 3. Due to the nature of the course, doing the laboratory requirement and the amount of material to be covered, there will a zero hour requirement two days each week. 4. You will learn to use a college text as a tool for your own learning. 5. You will develop a working background of common Greek and Latin roots in the development of proficiency in the language of biology. 6. You will become proficient in common lab procedures, perform basic college level laboratories, and design and execute an original experiment. 7. You will write numerous essay responses in both homework and unit tests as preparation for the AP Exam. 8. Again due to the amount of material that must be covered, you will complete the summer assignment attached. There will be a test the first week of school covering this material 9. Present selected topics to the class with handouts, power point, overheads, etc.

Summarizing, I am here to help you learn biology and thought processing skills to help you score as high as possible on the A.P. exam. We will discuss, practice, lecture and probably disagree at one time or another. I will help you any way possible but you will have to prepare before you get to class. Remember this is a college class. The scheduling is different and you will get more personal attention, but the pacing will be that of a college class. Coming from chemistry, you should have an idea how to learn a difficult subject. There is very little problem solving but the vocabulary can be overwhelming. It has been said the vocabulary in the text we use is equivalent to 4 yrs of a foreign language. I know you will be busy with many other activities and classes but you will have to make time to work on this class. There is an excellent essay on study habits on Robert Taylor's website from Stevenson High School. Here is the link It is on my website under AP Info/Help. You can get to my website: or go to Lafayette's homepage ( navigate through the department/science/teachers websites/AP Bio links. I have the first quarter plan from last year on the last page. This is not your plan but it will give you an idea of the pacing and types of things we do. The class picks up the pace as we continue through the year. Check back over the summer as I will be updating links and such to help us next year. There is an email link on the webwite. It will go to my email address at school. I will check the emails periodically over the summer. If you have questions or need help, send me an email and I will get back to you. If each of you would email me I can get a list to get information to you if I need to over the summer. I look forward to working with you in the fall and having a great class. Biology is a very interesting subject. Some Objectives for your summer work: (This will allow us to have time to review for the AP exam) I. PRINCIPLES OF ECOLOGY A. Compare and contrast energy flows and productivity within ecosystems. B. Discuss biochemical energy cycles. C. Demonstrate a working knowledge of community structure growth and regulation. D.

Here are some tips on writing essays for AP exams. · We will work on many of the techniques you will need for the essay portion of the exam during class. This will be enough to get you started. Unless your write very large try to keep your essay to two pages or less.

In answering these questions: · Be sure that you answer the question asked and only that question, and that you answer all parts of it. · Outline the answer to avoid confusion and disorganization. Thinking ahead helps to avoid scratch outs, astrices, skipping around, and rambling. · Write an essay. Unlike your English essays these do not require introductions transitions sentences and conclusions. The facts are what is important. Outlines and diagrams, no matter how elaborate and accurate, are not essays and will not do you much, if any, credit by themselves on the real exam. · Define your terms. Say something about each of the terms that you use

Latin Terms

Latin is the language of science. There are a few reasons for this but the most obvious is that Latin is "dead". Since no one actually speaks Latin, the language is not evolving(changing) so we have no confusion concerning the definition of a word. While Biology will not be as mathematical as chemistry or physics but it will be even more vocabulary driven. If you can define a word from it's parts rather than experience or going to a dictionary you will be ahead of the game. The following is a list of common prefixes, roots, and suffixes you will see in science. Knowing these will allow you to know the definition of many of the terms seen in A.P. Biolgoy. The words formed from these terms often are not literally fused together. It has often been necessary to add a vowel to combining forms for pleasing pronunciation. For example, bacteri- + logy becomes bacteriology. There are also times to drop or change a vowel in a prefix, suffix, or stem. For example, gastrobecomes gastric, the adjective pertaining to the stomach.", "a-, an-","no; lacking; none", "ab-","away from; out from", "ac-","to; toward", ",aceus; -aceous","of or pertaining to", "acou-","hearing", "act-; acro-","extreme; peak", "ad-","to; toward", "adeno-","gland", "agri-","field, soil", "-al","having character of", "alb-","white", "-algia","pain", "alto-","high", "ameb-","change; alternation", "amphibi-","leading a double life", "ampho-; amb-","both", "an-","not; without", "ana-","up", "andro-","masculine; man", "anemo-","wind", "angio-","vessel", "ante-","before; ahead of time", "antero-","front", "antho-","flower", "anti-","against", "anthropo-","man", "ap-","to; toward", "aqu-","water", "archaeo-","primitive; ancient", "arthro-","joint", "aster-; astr-","stars", "-ate","used in forming verbs from nouns", "-ation","used in forming nouns from verbs", "atom-","vapor", "audi-","hear", "auto-","self", "bactr-","stick; club", "barb-","beard", "baro-","weight", "bath-","depth; height", "bene-","well; good", "bi-","two; twice; double",
