TUESDAY August 31st, 2010 Conceptual Physics • LESSON GOALS: • Welcome new one • Check HMWK #1 • Respond to any major questions from Lessons 1 & 2 • Note: Hold off on the Energy-Transformation questions until the end of class. Those will not be due until Thursday. • Share responses to HMWK #1 (Scientific Method) • Complete Möbius Strip lab • Complete Thumb Wars lab • Assign HMWK #2 (finishing Energy Transformations labquest) http://mrlafazia.com/PHYS111/lessons/201011Fall/PHYS111_03.ppt 1/11
Caleb Gregory LaFazia • The reason we had two online classes: …cuter in real life… 2/11
HWMK Check! • This homework grade is based off of completion. • Get out HMWK #1 and as I come by show it to me. • If I have any questions, I will ask them while walking around. • If YOU have any questions, ask them of me as I check your paper. 3/11
Questions from Online lessons? • Lesson 1: Intro. to Course (and Scientific Method) • Lesson 2: Energy Transformations • Hold off on questions specifically about the E-Trans labquest until the end of class…this labquest will be due Thursday (next class). • Don’t Forget! If you signed up for my forum (it could make for a good resource, although it is entirely optional) then let me know now and I will make a note next to your name in my gradebook to give your user account access to your class’ section of the boards. 4/11
Sharing / Discussion • Share you experiences from HMWK #1: • Recall: • “PART TWO: Think of a time when you had a question (or a problem) which needed answering (or solving). Describe what this question/problem was. Then, go through each step of the Scientific Method and identify how you approached the question/problem.” 5/11
Ferdinand Möbius and his Extraordinary Strip • Observation: “There is a twist in this loop of paper!” • Question, Hypothesis, Experiment, Result w/ Conclusion… • The main purpose of this lab is to gain practice with using the Scientific Method. • There are a few steps to this lab. • I will be giving the instructions verbally. • Materials needed: pen/pencil, strip paper, scissors; tape. • This lab should be done in groups of 1. • On a piece of paper, title your lab “Möbius Strip Lab” and make sure that I can identify it as your work. This paper will include a record of all lab steps, observations, and findings and will serve as your lab report (which is turned in for grading at the end of the class period). 6/11
Thumb Wars! • Observation: “Some people win at thumb wars and some lose!” • Question, Hypothesis, Experiment, Result w/ Conclusion… • The main purpose of this lab is to gain practice with using the Scientific Method. • This is a lab “game.” I have a spreadsheet which we will use to keep track of “los ganadores”. • Materials needed: string, ruler; spreadsheet (to analyze results) • This lab should be done in groups of 2 (pairs which switch off continually). • On a piece of paper, title your lab “Thumb Wars Lab” and make sure that I can identify it as your work. This paper will include a record of all lab steps, observations, and findings and will serve as your lab report (which is turned in for grading at the end of the class period). 7/11
HMWK #2 • Complete the lab-quest (from Lesson 2). • Were there any questions from this? If so, ask them after the “Looking Ahead” slide that finishes the class. 8/11
Recommended Reading: Sections 5.7 – 5.12 (It just so happens that this is also REQUIRED reading for HMWK #2) 9/11
Poem: Methodically Scientific, by D. LaFazia "Dr. Watson!" Sherlock Holmes cried out, perceiving some new clue. "I spy a toad, upon this road, whose innards are now goo." "I wonder how they got this way," Watson did reply. "Certainly not willingly," the detective did descry. An Observation of this sort is nothing to be left. The Question formed was how the perpetrator perpetrated this grand theft. That life was gone--no question there--was obvious to them, But who had done this dirty deed and turned the toad to phlegm? "I do Propose," said Sherlock now, "that tires did the deed, "And furthermore, the Dunlop brand!" he brazenly decreed. "Why Holmes, old boy," the Doctor spoke, "how make you such a claim?" "My methods, Watson, you do know, and conviction is my aim." The duo traveled far and wide along the London street-- Searching here and checking there for frog guts on car feet. They checked Goodyear, Dunlop; Firestone too, For thorough Testing is what an objective scientist must do! "AHA!" blurted Sherlock, "See here, my good man! "I have found the death of this poor frog (who is flatter than a pan). "The deed was done, as I have said, with this rear Dunlop tire, "But I see justice has been done as well, for vandals have set the car afire!" "So it would seem," Watson proclaimed, as both men backed away. "But Holmes, how did you track it down--you've really saved the day. "I have to tell you, my dear friend, your Conclusions seem terrific!" "Nonsense, dear boy," Holmes replied with a grin, "They're Methodically Scientific!" 10/11
Looking Ahead: • Next class we will finish our formal look at the Scientific Method by completing The Famous Drinking Bird lab activity. We will then continue our look at Energy concepts. 11/11
