They noticed that the graphs for hot and cold water met right in the middle of both of the previous temperatures after being mixed. Next, each group mixed a set amount of water and observed graphs: Groups 1 and 2 mixed 1/4 cup hot water and 3/4 cup cold water. Groups 3 and 4 mixed 1/4 cup cold water and 3/4 cup hot water. text/html 2012-04-19T11:39:09-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day6:reflections&rev=1334860749 Student 1 Learned: Today helped me understand concepts about temperature more thoroughly. Wants to Know: What would you do with water on a grander scale and where can we go from here? Student 2 Learned: I learned how the temperature probes work and about measuring temperature. Wants to Know: I am still confused about the new concepts. text/html 2012-12-01T01:12:43-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day6:reviewing_pinhole_phenomena&rev=1354353163 We gave each group a white board and a pinhole scenario to sketch and solve for various measurements. Emily took the pinhole scenarios from a “Pinhole Camera Day” website (<http://www.pinholeday.org/>). She assigned each group a specific picture from the website to use for reference. After drawing a few sketches, each of the groups was able to come up with the equation: H/D = h/d Where: text/html 2012-04-24T11:40:26-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day6:reviewing_thermal_phenomena&rev=1335292826 Review of the thermal phenomena: * Objects left for a long time in a room reach the same temperature (room temperature) * Materials conduct heat energy at different rates * Styrofoam conducts heat slowly and is an insulator * Metals conduct heat quickly; metals are conductors * Conductivity: property of a material that refers to how quickly it conducts heat energy * Conductivity is different from density; conductivity refers to how fast energy flows through a material.
