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...

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...
