GENERAL CLASSROOM RULES & PROCEDURES
Classroom Rules
1. All school policies will be strictly enforced (including the makeup policies for absences).
2. All safety policies in the safety contract, workbooks, and this booklet will be strictly enforced; Failure to follow safety procedures will result in disciplinary action; Severe violations will result in the permanent removal from class.
3. Unnecessary pulling of the safety shower or eyewash fountain will result in a suspension.
4. Students not wearing appropriate clothing for lab (goggles, long pants/skirt, closed-toed shoes) will lose points on the lab; The teacher reserves the right to prohibit a student from participating in the lab if they do not wear appropriate clothing.
Makeup and Late Work
5. If an absence is excused, a student is allowed two extra days for each day missed; No credit is allowed for work for an unexcused absence.
6. You must see your teacher prior to a school related absence or field trip to make arrangements for makeup; Failure to do so will result in a zero for the assignment.
7. Late vocabulary words, practice problems, and/or practice tests for a quiz or test will be accepted one day late for half credit; Late labs will be accepted with a penalty of 20% per day.
Cheating
8. Any student caught communicating with others or using unauthorized materials on a quiz or test will get a zero for that quiz or test with no retake allowed; A major referral will be issued for gross insubordination/defiance and a phone call will be made home.
9. Although working together with a lab partner(s) on labs is encouraged, blatantly copying labs is also not allowed; Doing so will result in a zero for the lab.
Calculators
10. Students are strongly encouraged to buy a SCIENTIFIC CALCULATOR for this course. Scientific calculators are usually very inexpensive but can do exponents (Look for a key that says “EXP” or “EE”.). Because of issues related to cheating, NO GRAPHING CALCULATORS WILL BE PERMITTED ON TESTS (Sorry!)! Because of budgetary constraints, no calculators will be provided (Again, sorry!).
Grading Scale
11. The grading scale is as follows: A = 90-100%
B = 80-89%
C = 70-79%
D = 60-69%
F = 59% and lower
Final Exam
12. The final exam will count as 15% of the overall grade; To study for the final exam, students should review their workbook AND the textbook pages and key concept words listed in this booklet.
STANDARD PRACTICES IN THE LABORATORY
The science laboratory is normally a safe environment, but it is not free of physical and chemical hazards. Injury can result from broken glassware, fire, electric shock, and exposure to chemicals that can stain, cause skin irritation, spatter, and/or produce noxious odors. Standard safety practices have been developed to minimize risks in the science laboratory environment. By learning and following these practices, you will protect yourself and your classmates from potential injury.
SAFETY PRACTICES
1. PROTECT YOUR EYES. The State of Illinois School Code requires that goggles be worn when heating chemicals that are caustic or explosive. Safety goggles are provided in each chemistry laboratory. Only goggles provide maximum protection from spattering, splashes, and projectiles.
2. WEAR APPROPRIATE PROTECTIVE CLOTHING. When working in the laboratory, the following clothing items are not appropriate: sandals, cloth shoes, shorts, short skirts, and loose clothing. Closed, leather shoes and long pants or a long skirt provide maximum protection from broken glass, burns, and chemical spills. It is also recommended that watches, bracelets, rings, and contacts be removed and safely stored since they can trap chemicals against the skin and/or eyes and aggravate an injury. Tie back loose hair to avoid burning it, dipping it in chemicals, or getting it caught in laboratory equipment. Aprons are available in all chemistry rooms for further protection.
3. NEVER EAT, CHEW GUM, DRINK, OR APPLY COSMETICS IN THE LABORATORY. You may accidentally ingest and/or contaminate skin or eyes with harmful chemicals.
4. WHEN WORKING WITH CHEMICALS,
NEVER: taste them, smell them directly, pipette them by mouth, or remove them from the laboratory.
DO: flush the area with water if you spill any chemical on your skin or eyes; wash your hands with soap and water before touching your eyes, nose, or mouth AND when leaving the laboratory.
5. KNOW THE LOCATION AND OPERATION OF ALL SAFETY EQUIPMENT. Every laboratory has an eyewash fountain, fire blanket, fire extinguisher, first aid kit, fume hood, safety shower, telephone, and two exits. Report any accidents, spills, or unsafe equipment to your teacher immediately.
6. KNOW THE HAZARDS OF MATERIALS BEING USED. Metal and glass look the same whether hot or cold. Allow for adequate time for cooling. If in doubt, use the correct tongs or mitts. Many chemicals differ in only one letter but have quite different chemical properties and reactions (ex. copper (II) sulfate and copper (II) sulfite). A Material Safety Data Sheet (MSDS) Index is maintained for all chemicals used.
7. PEFORM AUTHORIZED EXPERIMENTS ONLY. Read all labels carefully to make sure you are using the correct chemical. Note all safety alerts provided with each experiment. Follow all experimental procedures exactly. If you want additional time or experience in the laboratory, you must consult your teacher. For safety purposes, there must be a teacher in the laboratory if an experiment is being conducted.
8. MINIMIZE ACCIDENTS. The chemistry laboratory is a place for serious work. Inappropriate and careless behavior will result in removal from the laboratory and disciplinary action. Return all chemicals and equipment to the proper storage area. Breakage and chemical spills must be cleaned up immediately. Notify your teacher immediately in the event of any accident, injury, breakage, fire and/or large spills.
HOUSEKEEPING PRACTICES
1. AVOID WASTE. Regardless of grade (technical, reagent, assay), chemicals used in the chemistry laboratory are pure. The cost of individual chemicals depends on production, quality, and quantity desired. Whenever you measure a chemical out of the stock container, carefully tap out the required amount; try not to waste. Likewise, distilled water is produced at the expense of time and electrical energy. Please be conservative when using distilled water to clean glassware.
2. AVOID UNKNOWN CONTAMINANTS. Lab jars should be taken to the weighing tables when measuring out a specified mass. Use care with the lids or stoppers of lab jars. Laying them down on the counter or switching them is a source of contamination. Make sure all glassware is clean. If you have any doubts, wash it with soap, rinse with tap water, and do a final rinse with a small amount of distilled water. Tap out solids directly from the lab jar into the desired container (if possible). Never insert a spatula, dropper, or pipette into a lab jar (unless given permission by your teacher). Pour a small amount of a liquid chemical into a small beaker and dispense it from there. Never return an unused chemical to a lab jar. You must assume that the chemical is contaminated. It is to be disposed of in the appropriate manner - solid chemical wastes are to be put in the solid chemical waste crocks or dropped into the trash can (if given by your teacher); Liquid chemical waste is to be poured into a designated container or flushed down the drain with an ample amount of water (if given permission by your teacher); Extinguished matches, paper towels, and other garbage should be placed in trash cans, not in the sinks or solid waste crocks. Use only distilled water when adding water to a chemical. Tap water contains contaminants that will alter the results of many experiments.
3. CORRECT WEIGHING PROCEDURE. The digital balances used are accurate to + 0.01 g. When using the balances, always make sure the window reads “0.00 g” before you start the weighing process. Pressing the TARE (ZERO) pad will return the balance to zero. Never put a chemical directly on the balance pan. If a chemical is to be added to some glass container, you may place the glassware on the balance pan and then press the TARE (ZERO) button. Now you can add your chemical to the glassware until the window shows the desired mass. Note that there is a delay before the measured amount is indicated, so add the chemical slowly to get the exact amount. The maximum load for the digital balance is 200.00 g. Make sure to clean up any spills on the balances.
4. CORRECT WASTE DISPOSAL. The custodial staff removes all non-chemical waste from two designated containers: the broken glass container, which contains all broken, chipped, or cracked glassware; AND the trash can, which contains waste paper, paper towels, and extinguished matches. Your teacher removes solid chemical waste from the solid chemical waste crocks and liquids from the designated containers.
5. EQUIPMENT SET UP. Most labs will already be set up for you; Please make sure you leave the lab equipment and chemicals as you found them (organized, clean, and dry) and that you close all lids and stoppers on chemicals. If a piece of equipment is not already set out for you, you will most likely find it either in the tall end cabinets of each lab bench or in the common property area along the wall; Set up your equipment away from the front edge of the bench so it does not get knocked onto the floor; Chemicals and other supplies for particular labs can be found in the labeled drawers on the back lab islands.
6. LABELS. Read the entire label on all chemical containers to make sure you have the correct substance and concentration. Inform your teacher immediately if a label falls off of a chemical container or is missing a label (and do not use it until it is fixed). When leaving an experiment overnight in the “Experiments in Progress” cabinet, be sure you label with your name, period number, and the date and place it on the correct shelf for your period.
7. CLEAN WORK AREA. Every chemistry student is entitled to a clean work area. When you are finished working, make sure your work area is breakage and spill-free. Return all equipment to its proper storage place. Make sure the gas and water outlets are shut off.

Guidelines FOR WRITING LAB reportS
It is required that you buy a graph-paper science notebook for recording and reporting laboratory findings. Every lab write-up must be checked off and/or initialed by your teacher prior to beginning a lab. The following format should be used.
Date Your name
Lab partner’s name(s)
Title of the Experiment
Purpose: Copy the purpose from the workbook pages.
Pre-lab Some labs will require you to look up definitions to key terms using your textbook.
Exercises: Others will ask you to answer questions to stimulate background information.
Procedure: Use a series of pictures, summarize in words, or do both to describe what you will do in the lab (DO NOT just copy the entire procedure word for word out of your workbook!).
Data: Write down all observations you make during the course of the experiment. Collected data should be organized into charts or tables whenever possible. Make sure that all measurements include the correct number of significant figures and units.
Analysis: Complete the list, calculations, analysis, graphs, and/or questions as directed. Make sure that all analysis calculations include the correct number of significant figures and units. Consult the Guidelines for Graphing for all graphs. Answer the analysis questions in complete sentences. Include/restate the analysis question as part of the answer. Do not use pronouns.
Questions: Answer the questions in complete sentences. Include/restate the question as part of the answer. Do not use pronouns.
Conclusion: Answer each part of the purpose. Do not use pronouns (Using them implies that your results cannot be repeated. If ten people are following the same directions, all ten should have similar results.). This section answers each part of the purpose, giving support from lab data, and includes at least two possible sources of error (Note: Sources of error should be experimental or technological design flaws or limitations with solutions whenever possible. “My lab partner didn’t read or calculate right are NOT acceptable sources of error.”).
Mind Prober: Answer the question(s) as they relate to the investigation you just completed. Use complete sentences. Do not use pronouns.
All lab reports are to be neatly hand-written in blue or black non-erasable ink (or neatly typed and spell checked if permitted by your instructor). Make all lab reports your best work. If you would be comfortable to have it on display and seen by others, then it’s good enough to be submitted for grading.

GUIDELINES FOR MEASURING
When using any non-electronic instrument designed for measuring, the reported measurement must include one number (digit) beyond what you can read directly when reading the printed measurement scale on the instrument. Another way of saying this is, when measuring, read any instrument to one half of the smallest scale division.
Meter Stick/Centimeter Ruler
A meter stick or centimeter ruler has a printed scale showing whole numbers of centimeters (cm) and small lines showing tenths of centimeters (or millimeters (mm)). Therefore, when reading a meter stick or centimeter ruler using significant figures, one would write the number of whole centimeters and tenths of centimeters using the printed scale and then estimate the number of hundredths of centimeters to the nearest 5 (i.e. If the measured object ended on a scale line, the measurement would end in a “0”; if the measured object ended between two scale lines, the measurement would end in a “5”.). As a result, all measurements with a meter stick or centimeter ruler should always be given to two places past the decimal (ex. 7.80 cm or 60.95 cm are possible measurements with a meter stick. 4 cm, 5.0 cm, or 84.200 cm are not!).
Graduated Cylinder
Since the ten milliliter (mL) graduated cylinder has identical markings (except that that they are vertical instead of horizontal) to a meter stick or centimeter ruler, a ten milliliter graduated cylinder should also be read to two places past the decimal. A 50 or 100 milliliter graduated cylinder has scale markings to the nearest one milliliter, so, unlike the meter stick or 10 mL graduated cylinder, it should be read to one place past the decimal.
Special Note: Make sure to always read the center of the meniscus (i.e. curved line) at eye level when reading any graduated cylinder.
Electronic Balances
Our electronic balances will automatically give two places past the decimal.
Special Note: Make sure balance is clean and tared (zeroed) before and after use. Also, make sure objects placed on the balance are cool and in an appropriate container for weighing (i.e. beaker, graduated cylinder, weighing boat etc.). Finally, if the balance readout does not “settle” fairly quickly, check for drafts from fans or open windows and doors.
Other Measuring Instruments (i.e. thermometers, burettes, pipettes etc.)
Use the general rule above and see your teacher for more specific instructions.

Guidelines for graphing
Line graphs are often used in experiments to provide a visual representation of the relationship between two variables. Following are guidelines, which are to be used when making graphs in this course. If the line has a positive slope, the relationship is described as direct. If the line has a negative slope, the relationship is described as indirect or inverse.
1. Use black or blue non-erasable ink (some labs may be typed … see your teacher for more details).
2. Be neat.
3. The data on the graphs must “fill the page”.
4. The origin of the axes must begin at zero.
5. The independent variable (data controlled by the experimenter) is plotted on the horizontal axis; the dependent variable (the resulting data) is plotted on the vertical axis.
6. Divide the number the divisions of each axis in such a way that the data is spread over the majority of the axis and the intervals on the same axis are equal in size.
7. Label each axis by printing the name of each variable, followed by the unit of each variable in parentheses; make sure to spell out the name and unit completely. Do not abbreviate (ex., Time (minutes)).
8. Plot the points and circle them. The circles, sometimes called error circles, both highlight the location of the data point and account for uncertainty.
9. Draw a smooth, solid line or curve between the data points. Do not “connect the dots”. This line should reflect the average trend of the data. It is possible that not all points will fall on the line.
10. Extrapolate beyond the data points with a broken (dashed) line. The extrapolated line should continue the trend of the line established by the data.
11. Place the graph title box in the largest empty area on the graph. The title should describe the information on the graph and is often the dependent variable versus the independent variable.
