we will be taking a closer look at these Gas Laws. Materials: • Two (2) Used pop cans • Heating source (Hot Plate, Stove Bunsen burner, or something similar) • Large Beaker, transparent bucket, or your kitchen sink . Cold Water - the colder the better! • A dozen (12) Ice Cubes • Tongs Cautions: • Make sure you wait until you observe plenty of steam being emitted from the pop can before you proceed to immerse it in water. Pop can will be quite warm, so be careful to avoid contact with any exposed skin. • Be sure workspace is clear of clutter and that there are no pets or small children playing around your feet. Just in case you lose your grip on the can or trip and the hot can drops. 10. Repeat steps 2-9 for the second pop can. Data: List/Present your observations in a table. Include amount of water before and after. Include before and after pictures. You are required to submit a full lab report for this experiment; Purpose, Hypothesis, Materials, Procedure, Data, and Discussion. Be sure to incorporate the following discussion questions into your writing. For details on proper lab formatting and what to include in each section please reference the document "Lab Format" under Resources. Questions to include in Discussion: (NOTE: These should be worked into the body of your Discussion, as a portion of the information the Discussion should include. This is NOT the whole Discussion. Please refer to the Lab Format Information Sheet and the Lab Report Example for proper section format. The Rubric included in the Assignment Folder will also help you with the formal lab write-up.) 1 Why was it necessary to heat the water inside the pop can? 2. Identify which gas law is being examined in this experiment. Using your observations as TIJ each section please reference the document "Lab Format" under Resources. Questions to include in Discussion: (NOTE: These should be worked into the body of your Discussion, as a portion of the information the Discussion should include. This is NOT the whole Discussion. Please refer to the Lab Format Information Sheet and the Lab Report Example for proper section format. The Rubric included in the Assignment Folder will also help you with the formal lab write-up.) 1. Why was it necessary to heat the water inside the pop can? 2. Identify which gas law is being examined in this experiment. Using your observations as examples detail and explain this gas law. 3. What could account for what happened to the pop can? Explain your reasoning. Connect your answer to your observations as much as possible. 4. When the pop can was pulled out of the water, what did you observe with regards to its shape, and the amount of water that poured out of the can? Give logical explanations for this observation.







rather some use liquid laundry detergent. Therefore the procedure would need to be changed to reflect this substitution. Data and Calculations: In this section of the report you include all of the observations that were made during and after the experiment. In this section you should also include all of your measurements as well as your calculations that were used to obtain your results. These calculations should be done in a step-by-step fashion to illustrate that you understand what is being asked of you and so numbers aren't abstract for the reader. It is also important that you include the proper units with your results, since the data would be meaningless without them. The results obtained in the experiment should be summarized in tables or graphs and be placed at the beginning of this section as a neat and organized way to present the raw data. With each table or graph be sure to include the caption statement. These statements should tell the reader what the Figure they are looking at is depicting. Remember statements for Tables are above the Table and statements for Figures and Graphs go below. PLEASE NOTE: You DO NOT explain or discuss any of the data in this section, as this section is only used to present the data to the reader. The explanations, comparisons, and discussion of data are done in the discussion section of the report. Discussion: The Discussion section of the report is one of, if not the, most important section in the lab report. It should be approximately 3/4-1 page in length at the least, be very detailed and cover all the information outlined below. Be careful of wording and phrasing as Discussions should have a flow to the writing and transition from paragraph to paragraph like a story. Also be mindful of choppy writing as it can occur when trying to incorporate the Discussion Questions into the body of writing. In this section of the lab report you bring all the information and data together. You will start this section by restating the hypothesis and stating whether it was supported or not. Provide evidence from the data section to illustrate this. This is also the section in which you describe and explain what the data means, and why it is significant through comparing values and results. You should include details on any unexpected results and try to explain or speculate what happen to skew the result. Following this you should move into discussing the potential sources of error (Human Error, Instrumentation Error, etc...) You should identify three (3) or four (4) of the potential sources of error and then for each one outline how these errors could have affected the data, and if the experiment was to be carried out again how one would either lessen the effects of these potential sources of error or eliminate them from the procedure altogether. After discussing the potential sources of error, the report should go on to talk about the validity and reliability of the data. By validity you should be thinking about and discussing if the results make sense and do they correspond to what was learned in the text. Reliability relates to the reproducibility of the data; meaning that if you where to carry the experiment out again would the results be very similar. Reliability comes with performing more experimental trials. Finally, the Discussion section should include the answers to the questions asked on the lab outline. These answers should be incorporated into the body of the writing as much as possible. A reader should never see discussion questions answered in a numbered sequence. To end the Discussion off you should have a concluding sentence or two that restates the hypothesis and that it was proven or disproven with reference to the key data.
