Safety Rules for the Chemistry Laboratory

  1. Be prepared to work when you arrive at the laboratory. Read the introduction and lab procedure the day before the lab is to be done. Write out the heading, title, objective, procedure and data table in your lab notebook the day before the lab is to be done.
  2. Perform only those lab activities assigned to you by your teacher. NEVER do anything in the laboratory that is not called for in the laboratory procedure or by your teacher.
  3. Work areas should be kept clean and tidy at all times. Only lab manuals (handouts), and notebooks should be brought to the work area.
  4. Clothing should be appropriate for working in the lab. Loose garments should be removed. Long sleeves should be rolled up. Do not wear open toed sandals.
  5. Long hair should be tied back, especially when working with an open flame.
  6. Jewelry that might present a safety hazard, such as dangling chains or bracelets, should not be worn in the lab.
  7. Follow all instructions both written and verbal, carefully.
  8. Safety glasses and a lab apron should be worn at all times in the lab.
  9. Set up apparatus as described in the manual or by your teacher.
  10. Always use prescribed instruments (tongs, test-tube holders, etc.) for handling equipment. Note, after heating, some lab equipment will remain hot well after the heating has been stopped. Do not grab any equipment that has been near a flame (such as ring stands or wire gauzes) unless your are certain that they have had sufficient time to cool down.
  11. Keep all combustible material away from an open flame.
  12. Never touch or taste a substance in lab unless instructed to do so by a teacher.
  13. Never put your face near the mouth of a container that is holding chemicals.
  14. When testing for odors, use a wafting motion to direct odors to your nose. Never smell any chemical unless instructed to do so.
  1. Keep flammable material away from a burner flame. Always turn the burner off when not in use. Never leave a lit burner unattended.
  2. When the valve is parallel to the gas jet, the gas vent is on. When the valve is EXACTLY perpendicular to the gas jet, the gas is on. Do not open the valve half way. Remember, it is either on or off.

AP CHEMISTRY LABORATORY WRITEUP

Title Page: Includes your name, date and title of the experiment Introduction (Purpose and Objectives) (10 points) This section tells the reader why you did the experiment. Include background information that suggest why the topic is of interest and related findings. It should contain the following:  (^) A statement of the purpose , scope, and general method of investigation in your study. Express the central question or questions you are asking.  (^) Descriptions of your experiment and/or hypothesis. Include a general description of what you have done and specifics about how you did the experiment. (For example: what chemicals were being reacted in the lab?)  (^) A list of any chemical reactions and mathematical equations used in this experiment. Procedure (Materials and Methods) (10 points) This section should describe all experimental procedures in enough detail so that someone else could repeat the experiment. Some guidelines to follow:  (^) Describe what materials, subjects, and equipment you used (Materials).  (^) Explain the steps you took in your experiment and how did you proceed (Methods). Results (Data, Observations and Calculations) (40 points) The results section should present data that you collected from your experiment and summarize the data with text, tables, and/or figures. Effective results sections include:  (^) All observations relevant to the lab should be stated.  (^) Data tables with titles, measurements, units and significant figures should be written out.  (^) All of the calculations which must be worked out with detailed explanations of what you have calculated and what the results are.  (^) Results made must be supported by both Qualitative and Quantitative information from your data and observations. Discussion (40 points) The discussion section should explain the significance of the results and give a detailed account of what occurred. Evaluate what happened, based on the purpose of the experiment. The discussion should contain:  (^) A summary of the findings of your observations, and explanation of why things occurred.

 (^) A description of the patterns, principles and relationships your results show. Explain how your results relate to expectations and to references cited.  (^) Sources of error and error analysis should be included if applicable to the lab.  (^) There will also be additional discussion questions that need to be answered. These questions MUST be written out.

HOW DO WE PROBLEM SOLVE?

Always remember to use scientific explanations to solve problems in a reasonable, logical and accurate way. This is true for any problem whether it is science related or not. Your lab report should reflect a well thought out scientific justification using a method of CLAIM-EVIDENCE-REASONING Claim: A statement of a student’s understanding about a phenomenon or about the results of an investigation  A one-sentence answer to the question you investigated  It answers, what can you conclude?  It should not start with yes or no.  It should describe the relationship between dependent and independent variables. Evidence: Scientific data used to support the claim Evidence must be:Sufficient —Use enough evidence to support the claim.  Appropriate —Use ONLY data that support your claim.  Qualitative , Quantitative , or a combination of both. Reasoning: Ties together the claim and the evidence  Shows how or why the data count as evidence to support the claim.  Provides the justification for why this evidence is important to this claim.  Includes one or more scientific principles that are important to the claim and evidence.
