The webpage includes: * (Day 1) shadows outside, shadow plots * (Day 2) pinhole camera: physics phenomena and explanation * (Day 3) pinhole camera: mathematical description and calculation text/html 2012-10-01T15:12:27-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:fall2012daybyday:fall2012day3:daily_schedule&rev=1349129547 . 9:30 - 10:10 Going on a Field Trip to the Roof to Observe the Moon and Sun 10:10 - 10:20 Reviewing Resources, Powerful Ideas about Light, Ray Diagrams, and Scientific Explanations 10;20 - 10:45 Using Mathematics to Estimate a Quantity of Interest: How Big is the Sun? 10:45 - 11:00 Reporting Findings 11:00 - 11:20 Beginning to Build a Webpage Documenting Learning about Light Phenomena 11:20 - 11:30 Writing 11:30 - 11:50 Reflecting text/html 2012-10-04T21:34:19-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:fall2012daybyday:fall2012day3:going_on_a_field_trip_to_the_roof_to_observe_the_moon_and_sun&rev=1349411659 This is a sky journal entery from the top of the roof. One arm was pointing at the sun and the other was pointing towards the western horizon, at the moon. We discussed the angle that the moon and sun formed and how that might change over the next few days. We also discussed how the moon might change over the next few days: set earlier/later, more lit/less lit, and what time would be good to look for the moon. text/html 2012-10-02T11:44:12-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:fall2012daybyday:fall2012day3:reflections&rev=1349203452 Student 1 Learned: understood the pinhole concept better, because of the visual realization with the sun ray diagram Wants to Know: why the moon seems to set a lot faster than the sun? Student 2 Learned: the similar angles and ratios with the ray diagram Wants to Know: if we are able to see the moon next class Student 3 Learned: the straight line that light travels in represented by the meter stick Wants to Know: why the moon had moved from the same spot at the same time one night to… text/html 2012-10-02T11:12:16-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:fall2012daybyday:fall2012day3:reviewing_resources_powerful_ideas_about_light_ray_diagrams_and_scientific_explanations&rev=1349201536 Resource Young children's pictures of the sun with straight rays leaving in all directions.
