Welcome to Biology! Hi – I am Mrs. Silber and will be your biology teacher for this year. I am very excited to have the opportunity to share my love for science with each of you. This year we will explore the amazing world of living things through a wide variety of experiments and activities. I am passionate about making biology relevant to each of you in your daily life and helping you to better understand the world around you. To accomplish this there are few ideas I want to share with you. Class Expectations: RESPECT –Everyone (including myself) will respect each other and our ideas. To make our class an open place where each of you can feel comfortable asking questions and sharing ideas we will respect each other. Attendance – You are an important part of our class and you need to be present (and on time) in order to contribute. I follow the HPHS attendance policy. Preparation – Everyone is expected to come to class ready to learn. This means bringing the appropriate materials, an open mind, and completing the required assignments. Communication – I will relay to you information regarding deadlines, your progress in class, and any concerns I have. I also expect you to come to me with concerns or questions you have in a timely fashion. I am here to help each of you succeed this year. I am looking forward to our adventures together! This year we will be covering many interesting and current topics in biology. Below is a list of the units we will cover and the learning targets for each unit. Evolution: 1. Discuss how chemical evolution proceeded from atmospheric gases to small organic molecules to macromolecules to protocells. 2.

My office is in my classroom, G 105. You are always welcome to come and find me when I am not teaching another class. Due to childcare responsibilities I will not be around before school. Please make an appointment if you need to meet after school as I don’t always stay. You and your parents may e-mail me if you are home sick or have concerns. I will return the contact within 24 hours. My e-mail is: ksilber@dist113.org . Please put your name or class in the subject line. You may also contact me by phone. My school phone number is 224-764-2280. I only listen to my voice mail once a day therefore e-mail is your best option. What do I need to bring to class everyday? You need a pen or pencil, your science binder or notebook, your text book (only when I tell you ahead of time), your lab manual, your school calendar, and any homework that is due. How will I be graded in this class? All points have equal value in this class. You can earn points on homework, in-class assignments, labs, quizzes, projects, tests, and class participation. We will use both formative feedback and summative assessment in the class and not all of it will be graded, though students can anticipate both verbal and written feedback from me. They can also anticipate self-reflection to be a part of how we monitor growth. Each quarter is worth 42% of your grade and the final exam and/or project is worth 16%. I will follow the school-wide grading policy. I do not round grades at the quarter or semester if you have turned in a late assignment. Therefore an 89.6% is a B+. % 93-100 = A 90-92 = A87-89 = B+ 83-86 = B 80-82 = B77-79 = C+ 73-76 = C 70-72 = C67-69 = D+ 63-66 = D 60-62 = D0 –59 = E How long do we have to complete our homework and what if it is late? The due dates of assignments will be clearly posted on the sideboard and announced in class. For most assignments you will have 3-5 days and labs about a week. Please see me BEFORE the due date if you know there is going to be a problem completing an assignment on time. If you don’t turn an assignment in on time it is 2 points off per day late for 5 days then it is a 0. If you are excused absent on a due date the assignment is due when you return. There are no make-up points for reading assignments and questions as we will discuss them in class the day they are due. However to have the opportunity for extra credit they must be completed. I will return assignments within 48 hours unless an unforeseen issue arises. Do you give extra credit? Optional extra credit will be offered once per quarter for an added 1% to your quarter grade ONLY if you have all assignments turned in (assignments might have been late but you must attempt every assignment). You will have a variety of options for extra credit which are on the portal site. In past years these options have included visiting a museum in Chicago, or watching an online lecture. What kind of tests will we have? Will we have pop quizzes? Unit tests will be announced and given at the end of each unit. These unit exams will be in a variety of styles including short answer, multiple choice, essay, and lab practices. Most quizzes will be announced in advance. Will we have lab partners? Yes, you will have lab partners. You will usually work in groups of 2 or 3. To allow you to work with a variety of people you will have different partners throughout the year. What happens if we break something in lab? You can avoid most accidents if you pay close attention to what you are doing. Always wear your safety goggles and follow safety guidelines during lab. Sometimes accidents happen even if you are trying to be careful therefore if accidents occur in lab notify me immediately so we can take care of the problem safely. Safety First! What about plagiarism? If your writing includes 5 or more words directly copied from a source- you need to place all the words in quotes and use an in-text citation or footnote. “Prion protein (PrP) plays a central role in Creutzfeldt–Jakob Disease (CJD) and other transmissible spongiform encephalopathies (TSEs)” (McCormack 2002). As a good guideline for your writing in any subject, a paragraph should have less than 25% quoted material. That means 75% of a paragraph should be written in your own words. Also, anytime you use a quote in your writing, you need to analyze or discuss it. Please see http://www.indiana.edu/~wts/pamphlets.shtml for information on how to avoid plagiarism. Note one can share ideas but you may not share words. Five words in a row taken from another source without quotes is a sign of plagiarism. Do not use Wikipedia as a source for any cited work. You can use Wikipedia as a starting point to orient you to a topic, but I expect that you find good sources for your written work. You should not use Wikipedia for any written research project. Most lab reports will be individual and while you will be working with a lab partner in class your lab reports must be your own work. I take this very seriously as does the school. One offense of plagiarism in ANY class is reported to the dean and a zero given of the assignment. A second offense goes on your permanent school record. Do you have any other polices that I should know about: I do have some strange rules and polices that are in place in order for us to start class on time and to maximize learning opportunities. 1. Turning in assignments/Staple Rule: Students may not use the classroom stapler after the bell rings for the beginning of class. It is student’s responsibilities to staple papers so we don’t waste time turning in papers at the beginning of class. You may have your own stapler but may NOT share it with other students. If papers are not stapled you will be deducted 1 point. All assignments that are being turned in should be in the basket the first minute of class. If you are not turning in an assignment on time you must place a piece of paper with your name and why it is late in the basket. 2. If students “shoot a basket” with trash and miss they come in at 7:45am and wash dishes or the floor. If they make the shot no penalty. 3. No touching stuffed animals on my desk or other objects. Many of these items were gifts from students and I do not want them broken or lost. 4. Do not write or erase ANYTHING on the side white board without my permission. This is where important information for all my classes is kept and it is not acceptable to alter it in any way. If you have special concerns… If you are in any special programs, including Special Education and Academic Assistance, adjustments can be made to help you succeed. Communicate your needs with me. If special circumstances arise, including extended illness, an illness or a death in the family, or any other circumstances that may affect you, please see me so arrangements can be made to help you succeed.
