Color and light

Image
The morning session began with the Limits of Light .  After the video introduction to the electromagnetic spectrum the class viewed the visible spectrum with CD spectrograph boxes. A digital camera does not produce the smooth blend of colors that make up the visible spectrum. During the Limits of Light video an image of a CD spectrum was captured for with the Pixel for use on the Blackview under a microscope. The Blackview phone was used under the microscope.  The microscope has been at ambient temperature for months down in the A101 cabinet. This is a scope that only the lower two powers are functional. The microscope is no longer used in biology.  The Limits of Light, CD spectroscopes, and microscope were all fit into the morning session. Given the video heavy morning session, the midday lab did not use the regular term introductory playlist. No pink is minus green, no pink shirt. Straight into laboratory eleven. This meant the "minus...

RipStik waves and the speed of sound

Image
In preparing the RipStik run four sheets of poster pad were inadvertently detached from the pad. This led to a four sheet run.  Gusting breezes were again problematic. With the plan to return the run track to A101, taping down was ruled out. Books were used to hold down the poster pads sheets. This meant ensuring the board remained on the centerline to avoid colliding with a book. The books are old textbooks no longer in use.Spring term attempted to use the classroom, but the track was almost invisible and staying straight down the centerline was hindered by the lack of sufficient lead in distance. The RipStik run on the board. The run was timed at 2.697 seconds. The white board allowed completing the wave on both ends, which led to the use of three seconds for six waves. The wavelength was calculated off of a single wave, not all six, and came in at 0.65 meters. The amplitude was 0.06 meters. All six waves were used to ca...

Weather Service Office Pohnpei visit and tour

Image
On Thursday 26 June the SC 130/1 physical science class visited the Weather Service Office in Pohnpei. Weather Service Specialist Wallace Jacob began by introducing the students to the services provided by the Weather Service Office.  Mr. Jacob explained the operations side of the office. Jonald, Rusty  Clayton, Eray listening  Jonald, Rusty, Clayton, Eray, Ruthy, Emars, Mary-ellen in a group photo. Weather balloon tracking station.  Current air pressure readings. Earthquake map, Ruthy and Emars listening. Tsunami monitoring station showing oceanic buoys. WSO Pohnpei is responsible for issuing tsunami warnings based on the earthquake and buoy data.  Forecasting model displaying precipitation, possible thunderstorms, here running the GFS model. Outside, Mr. Jacob showed the class the min/max thermometer, the air temperature thermometer, and the dew point thermomet...

Rocks, Snapseed, Google Slides

Image
As a summer experiment, laboratory eight was shifted from submitting a document with ten Rick characterized to a Google Slides presentation with five rocks characterized. Three videos led off the laboratory on rock types , minerals , and characterizing rocks . Then a presentation on how to use Snapseed to reduce image size, move to Google Slides, and submit in Moodle. An image of a rock was captured with the Tripltek tablet and then the process outlined in the slide deck was demonstrated on the tablet while mirrored to the Smartboard.  This variation on laboratory eight went well and made lab eight more useful to the students. During the regular term this will segue to a lab nine labelled cloud images slide deck. The lab went long wrapping after two o'clock. The last students left at 14:36. Jonald Some phones, including a Tecma (Android) and an iPhone 12 running iOS 16 were unable to run Google Lens. The Tecma displayed a message that Google Lens was not c...
