Title for Lab Background You will write some information on what you know about the lab you are investigating into. Problem Statement What question(s) are you trying to answer? Include independent and dependent variables and control (if appropriate). Hypothesis Write a possible solution to the problem. Make sure your statement in testable. Statement should reference your variables. Materials Make a list of all items used in the lab Procedure 1. Write a list of steps which explains what you did in the lab. Should be written so that anyone could repeat the experiment step by step! (like a recipe) Data Include a data table(s) and observations about the lab. Label all tables appropriately. Conclusion Accept or reject your hypothesis and explain why. Include summary of data. List any errors that could have occurred and what you would do differently next time you completed the lab. While each person is playing games, you must record temperatures of the PC with the side panel off using the thermal imaging camera or the IR thermometer. Please complete the following lab report as you work. You are investigating how hot do you think the computer will get and why? Please make sure you fix the spacing before handing it in. Be sure to take a few photos, you will need it post-lab (Hint hint... Thermal camera...). Pre-Lab Questions: 1. Describe the kind of airflow a computer should have. 2. What temperature should the computer be idling at? 3. What is the hottest temperature a computer can get at? 4. What other factors besides the hot-running components should be taken into account when talking about computer temperatures? 5. Which component do you think produces more heat? Post Lab: 1. What are some extraneous variables in this lab? 2. Do you think this computer's heating solution is effective? Why or why not? 3. Why is it important to have a cooling solution in a computer system? 4. Reflecting on your pre-lab questions, what were you right or wrong about? 5. Continuing question 4, what do you still wonder about heating and cooling? 6. Attach an image from the thermal camera, and explain what is happening. 80.7F Auto 89.8 BG= 68.0 11/30/10 72.1 {= 0.95 4:08:12 PM 81.2F Auto 86.4 BG= 68.0 11/30/10 70.1 &= 0.95 = 4:08:23 PM 83.1F Auto 86.2 BG=68.0 11/30/10 70.8 &= 0.95 4:08:40 PM 108.6F Auto 121.2 BG= 68.0 11/30/10 71.4 E = 0.95 4:17:52 PM 80.7F Auto 114.0 BG= 68.0 11/30/10 68.9 x &= 0.95 4:18:00 PM 89.5F Auto 110.2 BG= 68.0 11/30/10 70.3 &= 0.95 4:18:12 PM 119.0F Auto 129.0 72.8 E = 0.95 BG= 68.0 11/30/10 4:18:47 PM 85.6F Auto 89.0 67.2 &= 0.95 BG=68.0 11/30/10 4:19:01 PM
