Laboratory Roger Bacon said that science is the interrogation of matter. So, in chemistry the elements, themselves, are your teachers and molecules, your tutors. Yet, they tell few mysteries until they are pressed hard. So, you must think hard and work diligently to unveil the secret habits of atoms and molecules. And you must plan well, or else you’ll ask the wrong question and miss the subtle clues. You must watch carefully and record everything precisely, especially the crucial evidence, which power is revealed in the aftermath and your wayfaring thoughts "I wonder!" Now, when the beakers are drying and you sit with your team members beholding your data, you must dig at it with reason and inspiration, mathematics and determination, for the answers are all there, if you will but see it. Ahh! As you crack the nut and sit relieved and delighted that you figured it out, write it all out carefully as a memorial of your ingenuity. Lab journals: • I Saw has anything that I ask you to do, anything that you see in the lab, any calculations you do or questions you answer • I Thought has anything that comes from your head that is a thought about the procedure, observations, questions, new problems at the end. What predictions do you have? Why are you doing this step? Do your answers make sense? Did you predict what would happen correctly? Do you think you're right or do you need to do it over again? What could you have done better? Reflect! • Quick help: o MOST IMPORTANT: Remember to include ALL parts of the assignment. A good way to remember this would be to go through the lab and write on the back or another sheet of paper, everything the lab asks you to do. ALL of that must be in your lab journal when you turn it in. o Remember to put a cover sheet on your lab o Use the class debrief time to get answers to parts we go over. Getting correct answers helps your grade. Each lab has specific tasks to guide you. The rubric beneath describes excellent, good, satisfactory and unsatisfactory laboratory work. Noble Laureate (100%) o The lab journal is completed on time. The lab work is conducted in an efficient organized fashion and lab equipment is used properly.

The lab work is mostly completed in normal lab time. The student adheres to most safety procedures. The written responses demonstrate consideration of the material of the lab. The lab journal is fairly organized. Writing is understandable. Some graphs, charts and mathematics are neatly presented. Units and significant figures are used mostly accurately. Upgrade (75%) o Students should repair the lab journal within five days of its first grading and prior to end of the marking period deadlines. Late (75%) o The journal meets Lab Technician Criteria but it is turned in up to five days late. Trainee (40%) o The lab is completed but it does not meet the minimum criteria for Grad Student. No Credit (0%) o There are five ways to receive no credit. (1) Do not do the lab work. (2) Do not turn in the lab journal. (3) Turn in the journal more than five days late (4) Copy another's lab journal and turn it in as your own. (5) Be substantially off task during lab work time.
