Guilford High School

Student Safety Contract Science is a hands-on laboratory class. However, science activities may have potential hazards. We will use some equipment and animals that may be dangerous if not handled properly. Safety in the science classroom is an important part of the scientific process. To ensure a safe classroom, a list of rules has been developed and is called the Science Safety Contract. These rules must be followed at all times. Additional safety instructions will be given for each activity. No science student will be allowed to participate in science activities until this contract has been signed by both the student and a parent or guardian.

SAFETY RULES 1. Conduct yourself in a responsible manner at all times in the science room. Horseplay, practical jokes, and pranks will not be tolerated. 2. Follow all written and verbal instructions carefully. Ask your teacher questions if you do not understand the instructions. 3. Do not touch any equipment, supplies, animals, or other materials in the science room without permission from the teacher. 4. Perform only authorized and approved experiments. Do not conduct any experiments when the teacher is out of the room. 5. Never eat, drink, chew gum, or taste anything in the science room. 6. Keep hands away from face, eyes, and mouth while using science materials or when working with either chemicals or animals. Wash your hands with soap and water before leaving the science room. 7. Wear safety glasses or goggles when instructed. Never remove safety glasses or goggles during an experiment. There will be no exceptions to this rule! 8. Keep your work area and the science room neat and clean. Bring only your laboratory instructions, worksheets, and writing instruments to the work area. 9. Clean all work areas and equipment at the end of the experiment. Return all equipment clean and in working order to the proper storage area. 10. Follow your teacher’s instructions to dispose of any waste materials generated in an experiment. 11. Report any accident (fire, spill, breakage, etc.), injury (cut, burn, etc.), or hazardous condition (broken equipment, etc.) to the teacher immediately. 12. Consider all chemicals used in the science room to be dangerous. Do not touch or smell any chemicals unless specifically instructed to do so. 13. Handle all animals with care and respect. a. Open animal cages only with permission. b. Never handle any animals when the teacher is out of the room. c. Do not take animals out of the science room. d. Do not tease or handle animals roughly. e. Keep animals away from students’ faces. f. Wear gloves when handling animals. g. Report any animal bite or scratch to the teacher immediately.

14. Always carry a microscope with both hands. Hold the arm with one hand; place the other hand under the base. 15. Treat all preserved specimens and dissecting supplies with care and respect. a. Do not remove preserved specimens from the science room. b. Use scalpels, scissors, and other sharp instruments only as instructed. c. Never cut any material towards you—always cut away from your body. d. Report any cut or scratch from sharp instruments to the teacher immediately. 16. Never open storage cabinets or enter the prep/storage room without permission from the teacher. 17. Do not remove chemicals, equipment, supplies, or animals from the science room without permission from the teacher. 18. Handle all glassware with care. Never pick up hot or broken glassware with your bare hands. 19. Use extreme caution when using matches, a burner, or hot plate. Only light burners when instructed and do not put anything into a flame unless specifically instructed to do so. Do not leave a lit burner unattended. 20. Dress properly: long hair must be tied back, no dangling jewelry, and no loose or baggy clothing. Wear aprons when instructed. 21. Learn where the safety equipment is located and how to use it. Know where the exits are located and what to do in case of an emergency or fire drill. AGREEMENT I, ___________________________ ,(student’s name) have read and understand each of the above safety rules set forth in this contract. I agree to follow them to ensure not only my own safety but also the safety of others in the science classroom or laboratory. I also agree to follow the general rules of appropriate behavior for a classroom at all times to avoid accidents and to provide a safe learning environment for everyone. I understand that if I do not follow all the rules and safety precautions, I will not be allowed to participate in science activities. Student Signature: ______________________________________Date:_____________ Dear Parent or Guardian: We feel that you should be informed of the school’s effort to create and maintain a safe science classroom/ laboratory environment. Please read the list of safety rules. No student will be permitted to perform science activities unless this contract is signed by both the student and parent/guardian and is on file with the teacher. Your signature on this contract indicates that you have read this Science Safety Contract, reviewed it with your child, and are aware of the measures taken to ensure the safety of your son/daughter in the science classroom.

syllabus for L1 and accelerated chemistry all about this course

Welcome to chemistry! I look forward to working with you this school year. The purpose of this syllabus is to summarize the goals, content, grading policy, and class expectations for this school year.

what is everything made out of?

That is the essential question for this course- the same question that the we all naturally ask as we look at the world around us. It also makes one wonder why some substances are inert, while other substances react violently when mixed. For a few of you, opening your mind to the world of chemistry may change the course of your life (or at least your college major), as it did for me. For all of you this course will help you to understand the world around you. So, how do we answer this question? Certainly the most enjoyable way is to roll up your sleeves and find out for yourself. Teachers call this inquiry-based learning, and it is very effective (and, hopefully, fun!). We begin each unit by asking a simple question, and you and your lab partner then try to find out on your own. No, not by looking it up on wikipedia- by experiment. What you discover you aren’t likely to forget. It gives you a understanding of things that uses all of your senses. And, best of all, although it usually makes you question your own research, there are those rare occasions your own observations may make you question what the “experts” say, or the way that they say it. The best chemist is a skeptical chemist:

...by having Thus drawn the Chymists Doctrine out of their Dark and Smoakie Laboratories, and both brought it into the open light, and shewn the weakness of their Proofs, that have hitherto been wont to be brought for it, either Judicious Men shall henceforth be allowed calmly and after due information to disbelieve it, or those abler Chymists, that are zealous for the reputation of it, will be Robert Boyle oblig’d to speak plainer then hitherto has been done The Skeptical Chymist (1661)

The best chemist is a skeptical chemist. An original copy of The Skeptical Chymist (1661)from the University of Pennsylvania. Full text is available as is a scanned copy of the 1661 manuscript

Here are the units we will cover. Each chapter will last for 1-2 weeks, and most units will be tested individually. These 15 packets include or will direct you to everything you need to know about chemistry. Students receive paper copies of each packet, and it is online at the class website (chemistryacademy.org)

Grading Policy This class uses a “pure points” system: your grade will be determined by the points accumulated from homework, tests, and lab reports. For, example, you might earn 90 points on a 100 point exam, and 5 points on a 10 point quiz. Your average at that point would be 95 points out of a possible 110 total points for an “average” of 86%. Your grade can be accessed on PowerSchool, through the GHS website, also available on the chemistryacademy.com website. Test scores usually incorporate a citizenship component: arriving late to class or being unprepared results in a minor deduction for each occurrence. Assisting others and other meritorious behavior can lead to a small increase in your test score. During any type of testing, there can be no communications in any form with any other student(s). Should such communications take place, the student(s) will receive a grade of zero on the test. Be aware that it is a big deal if your cellphone is out for any reason during a test- this can result in severe consequences. What to bring to class All parents should receive an email a few days before the first day of class outlining what each student should bring on day 1. Each day students should bring: 1. A laptop or tablet. If you don’t have one a chromebook will be supplied to you in class. Check for updates on this since the school policy is somewhat fluid at this point. 2, A chronologically organized small 3 ring binder that includes the current semester of handouts, all additional handouts , and tests. 3, Loose leaf paper in the binder. 4. A scientific calculator 5. A pen or pencil 6. Your homework 7. Ear buds or Headphones for listening to screencasts. 8. A chromebook or laptop. On the first day of class you will receive this chapter, and each chapter will be handed out a the end of the previous one..Notebook checks occur during tests (5 points each), mostly to see that you are taking effective notes and completing all worksheets, and staying organized. The homework for each week is posted in the classroom and on powerschool. Have it out at the beginning of class so it can be collected. Sorry, no credit for Homework late homework.

in this class extensive use will be made of screencasts which include a scored follow-up quiz. Have a look at them at the chemistryacademy.org website; stay tuned for further details. Absences and Makeup Tests If you missed a class it’s easy to find out what you missed. The weekly schedules and homework are posted in class and on chemistryacademy.org. Rather than asking what you missed when you return from an absence, come in with your homework completed. For extended absences, check in with your instructor to schedule any makeup work. Note that an absence does not excuse you from your work; you will receive a zero until the work is made up. F With the exception of the hands-on labs, this class is fully set up for distance learning. All lectures have screencasts that can be viewed online, and each chapter is available online. Use your packet, go online. Watch the screencasts for each lecture. Complete the worksheets. Email me if you get stuck. Call your friends. Please try to avoid asking me “What did I miss?”- check powerschool first. Instead, say hello when you return to class and let me know that you are on track. Be aware that you will still have to take the test on the day scheduled, or soon after your return if you for excused absences. Makeup tests are available for verified absences. Sorry, no retests. 12

This course uses a series of chapters which are available online. Students are given a hard copy of each successive chapter during each chapter test Cellphones Please don’t take out your cellphone without permission. If it is impeding your work it may be confiscated. Media Privacy Occasionally there may be photographs or videos taken of us in the classroom. Although these are usually popular with the students and are good for class morale, it is important for each student to know that their right not to be photographed or videotaped is important and will be respected. Additionally, any photos or videos that are taken in the classroom will never be shared outside the classroom. Each student was mailed a media privacy form at the beginning of the year. Please let me know if you prefer not to be photographed or videotaped. Welcome to Chemistry! Please email me if you have any questions. Dr B Common Issues 1. Late to class Students who are late to class without a pass will receive a minor point deduction on their next test. Two tardies results in an email to your parents. Three tardies leads to a detention. 2. Arriving unprepared. Students who do not have a binder, calculator, and a pencil will receive a minor point deduction on their next test. Daily homework is worth 5 points, and is due at the beginning of class 3. Cellphones visible in class Once class begins, any cellphone seen will result in a 5 point deduction on the next test. Additional consequences such as detentions may follow. 4. Lab Groups of more than 2 To receive credit for a lab experiment your group must be no more than 2 students. 4. Absences and makeup tests Unexcused absences are treated in accordance with the student-parent handbook. Students are responsible for making up lost work and will still have to take each test. There are no makeups, but students may drop one test per quarter 5. Homework from other classes Will be confiscated if students work on it in class unless specifically instructed otherwise. 6. Students not seated or not in assigned seats Please remain seated in your assigned seat unless instructed otherwise to me marked as present. 7. Unsafe laboratory practices This is a serious offense and will result in immediate removal from class and administrative action.
