Suggested Soft Landings Strategies for Advanced Placement Science Compiled & Edited by: Robert Summers, A+ College Ready Lead Science Teacher Doris Chandler, Jefferson County Schools Lead ScienceTeacher Tammy Dunn, Jefferson County Schools Secondary Science Supervisor Major Grades-65% Unit Exams: There should be 3 unit exams in a 9 week grading period. Exams should mimic the AP exam; therefore, they should be graded like an AP exam--one full point GIVEN for correct multiple-choice answers and one-quarter point deducted for each incorrect answer. The maximum number of multiple choice questions on a unit exam for AP Biology is 50; AP Chemistry 38, and AP Physics 35. When the exam contains a free-response portion, the number of questions should be as follows: 1) Two 10 point essays for AP Bio; 2) 3 questions for AP Chemistry (comprised of problems and/or essays as appropriate); and 3) 3to 4 problems for AP Physics). For those not on the block or modified block schedule, two class periods will be needed. One class period will be devoted to the multiple choice questions and the other class period to the free response questions. Exams should be scaled according to AP standards. This means that if a student earns 75% of the multiple choice points and 50% of the free-response points, the student should receive a 100. If they exceed those expectations, then the student is on pace to earn a 5 on the AP Exam and can earn more than a 100 for that unit exam grade. A spreadsheet with the formulas for this type of computation is available from the lead teacher. Unit exams should account for NO MORE THAN 40% of the overall 9 week grade. Chapter/Concept Assessments: Because many units entail a large quantity of material, it is recommended that students be given more frequent assessments that allow BOTH the teacher and student to gauge student comprehension of major concepts. These assessments SHOULD NOT count as many points as the unit exams, but can be included in the “major grade” category. Lab Reports*(Lab Tests): There should be at least 2-3 of these given each nine weeks. A possible “recipe” for lab reports can be found on the AP Biology CD. It may be adapted to all sciences. A rubric for grading is also provided. Lab report/tests should account for 25% of the overall 9 weeks grade. Student lab reports may be done individually or as a group. The teacher must decide based on the type of lab done by the students. *An AP Chemistry Lab Report rubric is included along with a brief description of how to write a lab report. This material was created by Rene’ McCormick. A few minor changes have been made. Other Grades – 35% Quizzes: There should be 9 -20 quizzes given each nine weeks. These may be anything from vocabulary terms, worksheets, physical activities, presentations of current event topics related to science, homework assignments, etc. Quizzes should account for NO MORE THAN 25% of the 9 weeks grade. Students may be allowed to use their notes (taking notes represents effort beyond merely reading the text) when quizzed on the previous night’s reading. A typical did you read it quiz might include five questions on vocabulary (suggestion--paraphrase the definition to make the student THINK about it). The teacher may also do a spot check of homework or class work and occasionally give students an “effort” grade. For example, if students are assigned four problems for homework, they get a homework grade of 10/10 if they WORKED #3. This “spot check” does not require the teacher to take up anything to grade but holds students accountable for doing their homework. If a Classroom Performance System (CPS) or other type of signal device is available, teachers can give “clicker quizzes” to allow the students immediate feedback on their responses. These systems also do the grading for the teacher. Finally, it is a good idea to give an AP free-response question as a quiz. Grade the quiz by AP standards (a student earning 50% of the free-response points earns a 100 in the grade book). Students performing beyond this expectation are performing at a level on pace with earning a 5 on the AP Exam. Thus these students may earn grades above a 100. Artistic or Technology Projects*: ONE of these may be assigned each 9 week grading period. The project should encompass all content discussed during this time. Student work should give evidence of some research and include an artistic display and a brief report (no more than one typed page and/or oral report of no more than 5 minutes) or some kind of technological presentation. Projects can be presented as group projects, to reduce the volume of grading for the teacher. The artistic project grade could be broken down as follows: 50% artistic display, 25% oral report, 25% written report. The whole project should be counted as ONE grade and could account for up to 10% of the 9 weeks grade. SCIENCE IS MORE THAN READING THE TEXTBOOK AND TAKING TESTS. *If the AP teacher (especially AP Chemistry and AP Physics) is behind in their pacing, then this grade component may be omitted. It may take several years for a teacher to perfect percentages to suit their students’ needs. If these percentages are followed, it is difficult, yet not impossible, for students to fail. With hard work on the part of the student, an A is attainable. AP BIOLOGY LABORATORY WRITE-UP PROCEDURE I. LAB OR EXPERIMENT NAME- Be creative; but logical. Sometimes I reward really good titles with an extra point or two. II. INDIVIDUAL OR GROUP MEMBERS NAMES- If it is group members, they must be listed in alphabetical order. There must also be an asterisk next to the person’s name who actually wrote the lab writeup for the group. III. DATE OF EXPERIMENT- Put the date as the day you actually performed the experiment; not the date you turn in the write-up. IV. TEACHER’S NAME AND CLASS PERIOD(S) - Self-explanatory V. LIST OF MATERIALS AND QUANTITIES USED- You must list everything you used in performing the experiment, including the apparatus. If you used a liquid, powder, or other material you must give the total volume, mass, or other scientific measurement consumed for the entire experiment. (115 ml 1m naoh) VI.EXPERIMENTAL PROCEDURE- You must re-write the experiment in your own words. You must be detailed enough in your wording so that someone can perform the experiment exactly like you performed it. It must be in list format for each step. VII. PURPOSE- You must give a brief statement, one or two sentences, about what the purpose of the whole laboratory is trying to convey to your understanding of a topic. There is one unifying theme for each lab. VIII. HYPOTHESIS STATEMENT- you must write one sentence, in if…then… form, that gives your educated guess for the outcome of the whole experiment. i.e. If enzymes act as biological catalysts during a chemical reaction; then an increase in the rate of the reaction should be observed The IF part is your question you hope to answer. The THEN part is your educated guess about what the outcome of the experiment will be. IX. EXPERIMENTAL DATA AND NOTES- This is any observation you witnessed while actually performing the experiment. This also includes data tables or pictures. X. GRAPHS OR CALCULATIONS - These are items that are done after the experiment when you have all your data and observations. Make sure you have a proper title, labeling, units, and spacing when constructing a graph or chart! XI.CONCLUSION (Has 5 Parts)Part 1: Validity statement about the hypothesis. Part 2: Detailed explanation of the results from the experiment from each part and overall. Part 3: An explanation for any possible sources of error. Part 4: Ideas for ways to correct your errors Part 5: Ideas for expanding or furthering this experiment in terms of knowledge gained.

Heading: Title of lab, experiment number, date, period, name. Purpose statement: One to three sentences stating the purpose of the experiment. Procedure: Rewrite procedure from lab manual condensing yet emphasizing important parts. Keep in step form & keep in sections A, B, C, etc. Write cautions and warnings in bold print. Data: Data tables should be placed in this section. These should be like the report sheet provided in the manual (if present). Observations: These should be statements of qualitative, observed fact. Do not put ridiculous stuff. Make every effort to impress me. Pretend that your report will be placed in the hands of a scientist, who received the Nobel Peace Prize, to be read. Results: ]In this section you will record final answers, identification of unknown, calculated values, and [VERY IMPORTANT] relative error (other appropriate results may be included depending on the type of lab). Conclusion: This is where you draw conclusions based on results. Always refer back to the purpose and make that a part of your conclusions. This is NOT a place to express your opinion or observations of the lab. The conclusion should express results in harmony with the purpose and relative error. LAB REPORT GRADE*: 67% lab notebook 33% prelabs Prelab assignment--will be due the day that lab is scheduled to begin. Also due on that day will be the prelab write-up in your lab notebook. (Prelab write-up consists of heading, purpose, procedure & preparation of data tables.) Lab notebooks will be graded after each lab. All lab material is fair game for major tests! * suggested percentages
