Fruit salad

Image
This term Aone Mart and Ace Office Supply provided the necessary fruit salad ingredients. The coconut gel and pear slices came from Aone. I think the pineapple chunks and two cans on the right might also have come from Aone. The Essential peach slices, Essential fruit cocktail, Dole tropical fruit, and Dole mandarin orange slices came from Ace Office. The cocktail picks were perfect and came from Ace Office along with the bowls. There were enough left over bowls that the new bowl set was not tapped. The cans of fruit were purchased on Tuesday, 48 hours ahead of the class. They all fit into a box that was put in the refrigerator on Tuesday. Thursday morning the bowl, ladle, and can opener were also put in the refrigerator. The glass bowl was larger than that used in past terms. The coconut gel is in the bowl. I probably should have arrived earlier and set up the bowls in advance. I wound up dishing out fruit in real time with students present, which prevented a systematic loading of the...

Optics, reflection, refraction, total internal reflection

Image
 Monday began with Bill Nye the Science Guy's Light and Optics done from a DVD player and HDMI cabled into the Smarttech 6075S-V3-p SMARTboard. Wednesday I ran the laser demonstration of reflection, refraction, and total internal reflection. Thursday morning I stumbled into an empty aquarium. I would eventually fill the aquarium to the very top, along with various beakers and graduated cylinders. This makes the top of the container the top of the water and avoids the error students make of measuring to the top of a partially filled container.  The aquarium also provided a nice display of total internal reflection. I started with one plastic basin before I remembered I also needed an empty one. The objects were harder to see in the clear container, the white dish basin provided a better backdrop. I eventually put a towel on the faucets behind the containers to help reduce ambient light glare off of the surface of the water.  Halia, Ashlen, Serjean, and Sharla working on re...

SMART board and Lumio

Image
First use of the SMART board was limited by the board not having markers or erasers. About all that could be done with the board was showing children's videos. February 22 Yumie-Lani holds Anayva's son while Coco Melon plays Primary use by faculty is anecdotally reported to primarily be for slide deck presentations and online streaming videos.  With markers the annotation layer can be activated With the markers removed from the screen an annotation layer will appear, but only with the markers.  Early exploration and use focused on the whiteboards and some of the default templates built into the whiteboard app. The boards are SMART Technologies SBID-6075S-V3-P boards running a customized build of Android on top of a Linux core.  The markers and eraser appear to connect by Bluetooth as there is a USB receiver plugged into a service port. If this is the case, then charging is via magnetic induction while mounted on the board. Note that the markers and eraser are reversed abo...
