Lesson 1 – Introduction Objectives: - The student will learn the general areas of science covered in a chemistry class. - The student will learn the layout of this book. - The student will learn general study tips and tricks for use in this and other courses. - The student will review a safety contract for laboratory work.

I. Chemistry a. Chemistry is the study of the interactions between and among different types of matter. b. Some of the topics which will be covered in this class: i. How we can measure matter. ii. What matter is made up of. iii. How matter is put together. iv. What forms we can find matter in. v. How matter can change. vi. How different types of matter can interact.

c.Chemistry is the central science. A basic understanding of chemistry is necessary in all other sciences: biology, physics, earth science and all others. d.Branches of chemistry: Organic chemistry- study of carbon containing chemicals Organic chemistry- study of carbon containing chemicals Inorganic chemistry- study of non carbon containing chemicals Inorganic chemistry- study of non carbon containing chemicals Physical chemistry- study of the behavior and change of matter and related energy changes Physical chemistry- study of the behavior and change of matter and related energy changes Analytical chemistry- study of components and composition of substances Analytical chemistry- study of components and composition of substances Biochemistry- Study of matter and processes of living organisms Biochemistry- Study of matter and processes of living organisms

e. Chemistry is very much like learning a language. i.When learning some kinds of material, it is possible to take a test on that section, and then forget that material, since you won’t see it again. ii.In learning a foreign language, if you forget the basic vocabulary or rules of grammar, you will be unable to continue in the class. 1. You need to know how matter is made up in order to understand how it interacts. 2. You must be able to complete the earlier types of math problems, as they become part of the later types of problems.

III.This course is broken down into three areas of study: i.Lecture 1.These are the fact-based lessons, designed for minutes of lecture time. 2.They contain information about chemistry concepts. 3.They are generally presented in outline form. 4.In many of them, you will need to fill in information as it is covered in class. 5.There are generally questions following the material, which you will answer directly in this book.

ii.Math 1.These are mathematics based lessons, designed for minutes of teaching time. 2.They contain a short section of material including either example problems or room for you to copy examples as they are presented in class, followed by reinforcement problems. 3.Many of the problems are broken up into three categories: a.Initial, non-graded practice b.Graded practice c.Extra practice (if needed) 4.Sometimes, these topics coincide with lecture topics being taught. In other cases, they go in other directions.

iii.Laboratory 1.These are laboratory exercises. 2.These fall into two categories: a.“Cookbook Chemistry” – these are labs where the directions are spelled out for you, step by step. Generally, you will need to answer a series of questions following the activity. b.Discovery/Exploration – these are labs where you are presented with a problem, and need to come up with an experiment to solve the problem. Once the experiment has been completed, your report is in the form of a letter. 3.You will be required to review, sign, and have a parent or guardian sign a safety contract, before participating in any laboratory activity. Safety is our PRIMARY concern. Unsafe activities will not be tolerated.

IV.Study Hints and Tips a.Listen during the lecture, and write down important things. b.Anything the teacher writes down, you should write down. c.Anything the teacher repeats, you should write down. d.Anything the teacher indicates is important (“Important point here…”, “Make sure you understand this…”, “This is a key point…”, “This will be on the test…”, etc.), write down or highlight. e.Keep all of your notes together. Trying to find them at a later time is often difficult. Keep a 3 ring binder for all loose handouts. f.Review your notes nightly, or at the very least, every other night. Just reading them over once or twice will make a tremendous difference in studying for a test. g.If you are asked to do your homework on loose leaf, start each new assignment on a new piece of paper. If it is collected, you don’t lose anything overnight that you don’t want to.

h.If you miss a lecture, get the information that was given or gone over from a friend as soon as possible. Don’t wait until long after they were given, because your friend may not remember what the teacher felt was important. i.Homework is due the date it is assigned. If you are absent, you MUST come before homeroom the day you return to hand in assignments. If you wait until the next class it is already late and will not receive more than half credit. j.Do as many problems as you can for practice. The more problems you work, the better you will learn! Also, it is more important for you to understand how to do the problems than it is to get the right answer. k.If you don’t understand something, ASK! Don’t wait until before the test to ask a question from a while back; ask as soon as you don’t understand something. The only bad question is the one which is never asked.

V. Safety Contract a.The safety contract begins on the next page. b.Please read each point, and ask any questions you have about it. c.When finished, please complete the contract which is on separate paper, have a parent or guardian sign it, and return it to your teacher next class – This is for a grade! d.If you do not have a signed safety contract on file, you will not be permitted to participate in laboratory activities until this has been completed.

Collegiate Academy Science Safety Contract (adapted from Flinn Scientific’s Student Safety Contract) PURPOSE Science is a hands on laboratory class. You will be doing many laboratory activities which require the use of hazardous chemicals. Safety in the science classroom is the #1 priority for students, teachers, and parents. To ensure a safe science classroom, a list of rules has been developed and provided to you in this Science Safety Contract. These rules must be followed at all times. You have been provided with a copy of this contract in your book, and a separate copy to sign, take home and have signed by a parent or guardian, and return to your teacher by the assigned date. Review these rules periodically, to remind you or what you should and should not do in the lab.
