CHEEF benefits needs to display well on a midsize tablet. Bus arrival 16:46.  The weather was more than cooperative. The agriculture area is not a viable option. Not sure what to do with this field trip at this point. This term the class the class seemed to be unable or unwilling to settle in and sit around outside This lecture needs renewal.

The only forgotten thing this term was that the measurements are to be height in feet and circumference in inches. Which led to a need for conversions back in the classroom. Perhaps a machete might have been handy but ultimately proved unnecessary. The only diagram on the board prior to launch. This was effectively a cold launch to take advantage of the absence of rain at 11:00. The first tree was an Acacia auriculiformis that stood out in terms of height. Bentrick Ioanis was the first in and only one in to where the tree stood. This first tree was an informal test to see who were future foresters and who were perhaps not. The circumference measurement is targeted to be at chest height. Jayleen David was second furthest into the forest. iNaturalist was used to record both the tree species and the circumference, height data. The notes field was used for measurements. Jayleen would prove to be in a critically needed...

35 blue and 15 green marbles were out into a cloth bag. 14 students were present at the time of the draw. This exercise was used to demonstrate sample versus population probabilities. Of course if additional students were to come in the next estimate should be based on Bayesian statistics.

The short answer quiz question type in Moodle, known in Canvas as fill in the blank, only shows the first correct answer when there are multiple correct answers. For the above question there are actually 17 correct answers. The first correct answer happens to be kartop, the name of the plant in one of the local languages. In the above image the student has answered correctly for their language, and they were awarded full credit. The question behaved properly. All questions, whether correct or not, display the first correct answer as seen above, upon submission of the quiz or test. Learning is facilitated by immediacy of feedback, in this course tests display correct answers upon submission.  The result of displaying the first correct answer, in this case kartop, causes confusion for both students who answered correctly and those who answered incorrectly. In the above case the student might not notice that they were awarded full credit for their correct Kosraean answer. In the above...

I distributed ten pennies to each of the seventeen students and had them shake up their pennies and drop them onto the table. This was a cold open to probability. After noting that five heads (and five tails) was not the most frequently occurring combination, I calculated the mean. 6.47 heads, or a 65% to 35% heads to tails split. Hardly 50/50. While this is technically probability as relative frequency, this will help set up the blue-orange marble exercise on Wednesday while still providing an introduction to probability and random variation.  After the ten penny exercise coverage of coins, dice, urim and thummim followed. The ways to get a desired outcome over the total possible outcomes. 

Friday of week five, the wrap up of motion and dynamics. The concept was to tow the instructor on the RipStik in two directions to directly measure the force of friction. Starting position with Josh on towing duty There is a slight slope. Nine Newtons was seen on the downhill runs. 13 to 15 Newtons on the uphill runs. Six yarn strands were sufficient. Tow underway. Based on a 9 to 13 range, the frictional force was estimated to be around 11 Newtons.  On Monday the downslope force was measured at 43 Newtons. The change in momentum with respect to time was 14 Newtons. 43 minus 43 minus 11 lost to friction is 32 Newtons of effective downslope force. 14 Newtons showed up as the change in momentum with respect to time. That leaves 18 N unaccounted for. The theoretic downslope force is only 19.74 N based on F=mg sin(θ). The 43  measured Newtons remains unexplained. 19 minus 11 is 12 N, very close to the 14 obta...
