1st lab report Rolling Dice Lab         Assigned Thursday, 09-04-08, due Monday, 09-07-08   Rolling dice – craps, gambling, set up so house wins With 2 (6 sided) dice, what is the chance of rolling a 2,3,4,5,6,7,8,9,10,11,or 12? The goal of this lab is to answer this question. To simplify matters each student will only do the calculations for one of the above numbers (assigned by the instructor). 1. Observations Why were we interested in the topic?    10pts –        describe the dice. What shape is it? How many sides? Do the sides look different? Is there an equal chance of landing on any side? You could discuss craps gambling and chance of winning here. 2. Hypothesis This should be a statement that can be tested by experimentation.   10pts  – for your number between 1 and 13, using logic, make a prediction about what percentage of the time you will get a sum of that number when you roll your two dice. How many ways can you role your sum. Explain the logic you used to come up with your hypothesis. 3. Experiment: How was the experiment conducted? Procedure, steps of experiment. 40pts Results:Data and experimental observations:   10pts –        Design an experimental plan, write your plans in numbered steps. Include how many times you will roll the dice. (This should be at least 50 times and no more than 200 unless you plan on finishing the lab at home.) How will you record your results? Design a table with 12 columns numbered 1-12. –        Execute the experiment (do the experiment) Record your results and any relevant observations. 4. Analysis: This should include any charts or graphs of the data and interpretations of the graphs.   10pts –        What does your data mean? What percentage of the time were you actually roll your number? Explain any calculations you make. 5. Conclusions: Was your hypothesis supported by the data or not?   10pts  – What was the measured percentage that you actually came up with? Is this different than your hypothesis? Is it close to your hypothesis or not? Based on the results, do you accept or reject your hyothesis? 6. Repeat – could anything be gained by repeating the experiment? Would you do anything differently? Are there any modifications or related experiments that you can think of that would be interesting?  10pts 7. Report – write a lab report. This should contain 6 sections corresponding to each of the above parts of the scientific method. Each section should be in paragraph format with complete sentences. The one exception to this rule is the experimental section which can have the steps listed in order.
