We asked the students to face north and point, using their arms, towards east and west. Next, we asked the students to face in a direction where they were able to see the sun and moon. They all turned to face south. The students oriented themselves again by determining which directions are east and west. From there they drew a line along the bottom of their sky journal to represent the horizon, then labeled the line … text/html 2012-04-05T11:09:09-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day2:daily_schedule&rev=1333649349 9:30 - 9:40 Discussion about sun, direction of sun, and Sky Journals 9:40 - 9:50 Sharing findings about light and shadow phenomena 9:50 - 10:20 Documenting current knowledge 10:20 - 10:40 Observing the sky 10:40 - 11:20 Exploring “Pinhole Phenomena” 11:20 - 11:30 Writing 11:30 - 11:50 Reflecting text/html 2012-04-05T11:29:31-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day2:developing_powerful_ideas&rev=1333650571 Light travels in straight lines. text/html 2012-12-01T02:22:11-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day2:documenting_current_knowledge&rev=1354357331 The students completed a diagnostic questionnaire about their knowledge about the sun and the moon: * Why does it get dark at night?* Why is it cold in the winter and hot in the summer?* Why does the moon seem to have different shapes at different times?* How would you define a “scientific explanation”?* How would you define “inquiry approaches to learning and teaching”? text/html 2012-12-01T00:46:49-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day2:pinhole_phenomena_experiment&rev=1354351609 We gave each of the students a toilet paper tube, two rubber bands, a small square of both wax paper and aluminum foil, and a pin to create a small hole in the aluminum foil square to create pinhole cameras, which look like this: We turned out the lights in the classroom and asked one group at a time to approach a lamp with their pinhole cameras pointed towards the light, and using their pinhole camera, to observe the image that is created on the wax piece of paper. Students observed an… text/html 2012-04-05T11:44:17-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day2:reflections&rev=1333651457 Student 1 Learned: I thought it was interesting to see why mirrors are used cameras. Wants to Know: I'm wondering if different materials make a difference in the pinhole camera. Student 2 Learned: I understand better how light leaves its source in all directions and travels in straight lines. Wants to Know: I want to experiment with a pinhole camera using a different light bulb. Student 3 Learned: Wants to Know: In regards to the yard stick experiment, if there are many shadows on t… text/html 2012-12-01T02:21:08-08:00 http://sites.science.oregonstate.edu/physics/coursewikis/ph111/doku.php?id=days:spring2012daybyday:spring2012day2:start&rev=1354357268 Daily Schedule Documenting Current Knowledge Beginning Sky Journals Developing Powerful Ideas Pinhole Phenomena Experiment Reflections
