If you have earned 1275 points, you are guaranteed an A (90% + 150 lab points); 1150 (80% + 150 lab points) points guarantee a B; 962 points a C (65% + 150 lab points); and 775 points guarantee at least a D (50% + 150 lab points). All of these totals include the 150 points for laboratory attendance. To earn a/an A, B, C, or D, you must have the 150 laboratory points. Your letter grade for each item will be indicated when it is returned. Three hour examinations in lecture will be given. If you take all three exams, your lowest score will be dropped. If you miss an exam, that is your lowest score. No make-up examinations will be given. Scores are posted on Blackboard. Your letter grade for each item will be indicated when it is returned.

In-class quizzes are unannounced. You will be able to work with other classmates to answer the questions, but not use your notes or the text. If you miss the class, you will receive a zero for the quiz. These quizzes cannot be made up. Latecomers work alone.

Twenty-six pre-lab quizzes must be completed before the lab begins (10:30 am the day of the lab) on Blackboard. Your lowest six scores will be dropped, if you take all of the quizzes. If you miss a quiz, that is one of your lowest six scores. No make-up quizzes will be given under any circumstances. Print/save these quizzes, if you want to use them for review for the lab practical.

Nine laboratory quizzes will be given. If you take all of the quizzes, your lowest two scores will be dropped. If you are late for class, you will not be allowed to take the quiz. If you miss a quiz, that is one of your lowest scores. No make-up quizzes will be given under any circumstances. Late laboratory and field reports. are not accepted.

A maximum of 40 points (20 points each) extra credit may be earned by presenting oral reports on 29 September and/or 13 December. The complete articles for these reports must be shown to the instructor by 10:30 am on 22 September and 29 November before the report. The articles must be from a scientific magazine, journal or on-line journal. The article must be three pages long and be about a botanical or plant ecological topic. Information from a website is not acceptable. A page of instructions on how to do these reports is attached. Difficult articles and good presentations earn more points. A copy of the article must be turned in to the instructor on the day of the report. This is not a research paper; the presentation should be about the article which you chose.

A maximum of 15 points each may be earned by completing experiments 1,2 and/or 3 in the laboratory manual and turning in the pages from the manual on 10 November, AND the plants you have grown. You must bring in the plants (they must have sprouted) as well mid semester on 6 October. The appropriate number and kinds of plants must be turned in to receive credit for experiments 1 and 2. You need to figure out which plants are necessary to answer the questions and label the diagrams and then grow them. Sections of the reports which are not documented by plants, will not be counted. These last projects should be started at the beginning of the semester and are independent and individual. You will not receive credit, if your data matches that of someone else or if the answers to the questions are identical/similar. You must have plants to show me mid semester and to turn in at the end of the semester to receive any credit.

"Stars" are awarded for answering questions correctly in lecture or lab, good technique, good drawings and demonstrating your knowledge of slides by pointing out the components during "slide review". Stars translate into extra-credit points at the end of the semester.

Ground Rules:
There are no make-up examinations in lecture or quizzes in lab. You forfeit the ability to drop your lowest score(s), if you miss a lecture exam or laboratory quiz. If you anticipate missing a laboratory practical or the final examination in lecture, please inform the instructor in advance. If you are ill and miss either of these examinations, you must contact the instructor that day (kpihl@laspositascollege.edu) and leave a message which includes a phone number and time when you can be reached. You must document that you have been under the care of a physician. Other reasons such as funerals, ill children or other family members must also be documented in writing by a funeral announcement or by a medical professional. Vacation travel is not an acceptable excuse. Failure to attend the final examination may result in an "F" grade, if arrangements are not made that day or before.

You will receive 150 points at the end of the semester, if you have attended every lab and field trip. If you miss a lab or field trip, fifty points will be subtracted from this total. IArriving late results in a two point deduction. Points will be deducted for leaving early. NOTE: Attendace is taken during the last twenty minutes of lab.

If you miss a lab due to illness or participation in a sporting event for LPC, you must obtain a written, signed and dated note from your physician or coach and you must arrange to make up missed laboratory work within one week following the lab. No more than one laboratory may be made up during the semester unless extenuating circumstances exist. Other absences such as funerals, ill children or other family members must also be documented in writing by presentation of the funeral program or by a note from a medical professional. Vacation travel is not an acceptable excuse. You are responsible for making up the lab when the instructor will be present and that the supplies you need will be retained by the Laboratory Technicians. The only time available for make-up labs will be when the instructor is holding office hours in the Science Center (9:30 pm-10:20 am, Thursday). You will need to inform me and the Lab Technician staff in advance that you will be coming to make up a lab. All make-up labs must be filled out completely and turned in. Some labs can only be done on the scheduled day. If you miss one of these laboratories or a field trip, a research paper will be assigned. Needless to say the best policy is to attend every lab.

Laboratories in this class may require additional work at unscheduled times. You should NOT expect that all of the experiments will be finished in the three-hour laboratory period and to adjust your schedule accordingly. This is typical of the real world of scientific research.

For some laboratories you will be randomly assigned to groups. You will work together and write a single report. All students in the group will receive the same grade. As part of the report you will include a work sheet signed by all members of the group indicating the share of the work each individual did on the assignment. If there is a problem with a member of your group, you should inform me as soon as possible, preferably before the report is due or you may choose to write the report individually.

If you are absent for a total of four consecutive or six cumulative lecture classes you may be dropped from the class unless you have explained your absences to the instructor. If your behavior is disruptive or immature, you will be asked to leave the class and you must see the instructor before returning. It is important to recognize that the instructor cannot drop you after the "W" deadline.

Dropping the class. If you decide not to continue in the class, please use CLASS-Web or go to Admissions and Records and drop yourself. You do not need to involve the instructor. Do not assume that the instructor will drop you for not attending the class.

Lecture and pre-laboratory outlines and the pre-lab quizzes are provided on Blackboard. It is suggested that you print the pre-lab outlines and lecture outlines and bring them to class so that you may take notes on them. Some pre-lab quiz and quiz questions come from the pre-lab information.

If you are caught cheating, a report may be submitted to the Vice President of Student Services for investigation and disciplinary action. Examples of cheating: copying test or quiz answers, copying lab reports or answers to questions on the lab report, copying someone else's data from lab, copying material verbatim out of a book or from the internet, not citing sources of information in a report. If you either give your lab report to another student or copy a lab report or portions of it, you will receive a zero for the report. If you copy quiz or test answers from another student, or change answers on a returned quiz/exam, the grade for that quiz/exam will constitute one of the dropped grades. Reports must be submitted to SafeAssignment in Blackboard the day and time they are due as well as to the instructor in order to receive credit. Late reports are not accepted. If a portion is not submitted, that section will not be considered.

Manners and success tips. Be on time. Don't come in late and slam the door or scrape your chair on the floor. Enter quietly. Come to every class. Read all of the assignments. It is especially important to read the labs in advance. Highlight tasks and questions to be answered in your manual. Take notes and read them as soon as possible after each class. Make an outline of the important points in the lecture. Clarify what you do not understand--come to office hours, send an email, form a study group, sign up for a tutor in the Assessment and Tutorial Center (2401). Resist the urge to fall asleep. Not only will you not learn anything while snoozing, but also it really annoys the instructor (something you want to avoid). Bring something to write with and on. Bring Scan-Tron sheets on the day we have exams. Make sure that your pencil is sharp before the instructor begins. Tearing open your candy bar wrapper or chips bag is disrupting to the class.

Cell phones must be put away so that they are not visible during lecture and lab. Reading your messages or text messaging during class is rude behavior and may result in 20 points being deducted from your total accumulated points.

You may not eat or drink anything in the laboratory, including water, and you must wear shoes with closed toes and heels or you will not be allowed to enter the lab. Safety goggles are required for some labs. We provide used goggles or you may bring your own, but they must fit against your face.

Return to top.

Back to page 1.

PROCEDURE FOR ORAL EXTRA-CREDIT REPORTS:

1. Select an article from a current (published within the last three years) periodical that relates to the course you are taking. (If you are in Botany, it should be about some botanical or ecological problem or principle.) Examples of periodicals in the Las Positas LRC that may be used are:

 

 Sample Periodicals:  
American Forests National Geographic
Audubon National Wildlife
Bioscience Natural History
California Wild Nature
Chemical and Engineering News Nature Conservancy
Discover Science
Environment Scientific American
JAMA Sierra
  Smithsonian

Livermore, Dublin and Pleasanton Libraries are also sources of science periodicals. EBSCO Host is a good source of articles. Use Academic Search Premier found on the library website.

2. The article must be at least three pages long. Short newspaper articles are not acceptable, nor are articles from popular magazines such as Reader's Digest, Muscle and Fitness, Good Housekeeping. Online journals or periodicals from the internet may be used; however, you may not give a report simply about information from a particular website. Acceptable sites should have a date and volume. If you are not certain, ask your instructor before the deadline date for approval.

3. Read the article to make certain you understand basically what it is about. (It is impossible to present an oral report on something that makes no sense to you.)

4. Bring the entire article (or a copy) to lab on the deadline date or before; this is usually one-two weeks before the reports are scheduled. See the syllabus for the exact date. Your article must be approved by the instructor in advance. Articles are not approved after the deadline.

5. You may use notes and audiovisual material. If you require media equipment, you need to inform the instructor one class period in advance of the presentation. old computers, Make certain before the day of the presentation that one of the two computers will read your file. If your are using the latest version of PowerPoint, you may need to save your presentation in an older version. Be sure to test this before the day of the presentation.

6. Your report should last 10-15 minutes. Make certain you announce the name of the publication, name of the article, author(s) and the date of the periodical.

7. No written report is to be turned in. This is not intended to be a research paper on a particular subject. Only one article is to be used. Turn in the article itself the day of the oral report

8. Points are awarded based on the difficulty of the article, use of audiovisual materials and the quality of the presentation. Try not to simply read from your notes.
