First, they decided to connect five batteries to four bulbs (1 series, 3 in parallel). The students predicted that the single bulb would be dimmer because there is more resistance, because the bulb is not connected directly to the battery. We found that only bulb #1 would light when the entire circuit was connected. However when we made a direct connection between the battery and the … text/html 2012-02-09T11:31:10-08:00 days:winter2012daybyday:winter2012day10:reflections http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:winter2012daybyday:winter2012day10:reflections&rev=1328815870 Student 1 Learned: “Numbers make more sense to me than technical terms.” Wants to Know: “How does this all apply to wiring in houses and other real-life circuits? I'm thinking about things on a bigger scale.” Student 2 Learned: “I learned more about the 'neutral thing' and the properties-- that it's a + and a - together. I liked clarifying what they are.” Wants to Know: “Deciphering between the terms to use still confuses me (current, flow, resistance, etc.)“ Student 3 … text/html 2012-02-09T11:19:57-08:00 days:winter2012daybyday:winter2012day10:review_of_electrostatic_phenomena http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:winter2012daybyday:winter2012day10:review_of_electrostatic_phenomena&rev=1328815197 Emily gave the students a quick review of electrostatic phenomena (which we modeled using charged pieces of tape). We reviewed the main ideas of how to solve an electrostatic problem being modeled using tape: 1. Look first for tapes which repel each other. We know they're charged (not neutral), if they are repelling each other and that they have the same charge, because like charges repel. 2. Recognize that neutral tapes are attracted to charged tapes. 3. Unalike charges attract, while like… text/html 2012-02-09T12:04:42-08:00 days:winter2012daybyday:winter2012day10:review_of_magnetic_electrostatic_and_circuit_models http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:winter2012daybyday:winter2012day10:review_of_magnetic_electrostatic_and_circuit_models&rev=1328817882 A few of the students had some trouble with a homework question which asked them to review and reflect upon what our exploration of current electricity so far in class. The question continued, what models of electricity have we considered, and what is the evidence in support or not in support of each model? A couple of the students provided very brief explanations of our exploration, however the work that is required for this class should pull together everything that we've done in that particul… text/html 2012-02-09T12:06:38-08:00 days:winter2012daybyday:winter2012day10:review_of_magnetic_phenomena_homework_question http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:winter2012daybyday:winter2012day10:review_of_magnetic_phenomena_homework_question&rev=1328817998 The students were given a problem in their homework which asked them to think about magnetizing paperclips. Emily reviewed the following main points for talking about this kind of situation: 1. North and South domains can not be separated. 2. Goal is to align all North and South domains. One of the students asked the question: “Does each paper clip magnetize the next one following it, or is each paperclip effected by the magnetic field?” She answered her own question by saying … text/html 2012-02-09T11:14:35-08:00 days:winter2012daybyday:winter2012day10:start http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:winter2012daybyday:winter2012day10:start&rev=1328814875 Daily Schedule Review of Magnetic, Electrostatic, and Circuit Models Exploration of Electric Circuit Phenomena Review of Electrostatic Phenomena (Homework Question) Review of Magnetic Phenomena (Homework Question) Reflections
