Power off until 8:54 put the lab into a more traditional mode. No Smartboard support. Board at the end of the 8:00 section. Three groups, three sets of times, three different accelerations of gravity. The mean, however, was 9.81 meters per second. There was no plan to introduce the published value, but the average forced the issue.  Notes from the end of the 8:00 lab session Maicalany dropping a ball from four meters above the ground Four and five meters are done outside Moki holds the meter stick while Kayla drops from one meter Trevor holds the meter stick, Trishelle drops and times Ikaia shows a time to Marikai, Hailey holding the meter stick Kayla drops and times, Moki holds the meter stick Franchesca drops and times, Jaymar records data Ikaia displaying a time for a two meter drop, Hailey holding the meter sticks Maileen recording data...

The walk began on a cold open perhaps three minutes ahead of the bottom of the hour. Volkameria inermis was first up, followed by Scaevola taccada. Morinda citrifolia is omitted from this walk to leave that oft chosen tree for student presentations the following week. A healing plants walk and talk guide once again proved invaluable in the field. By 15:44 the group of 27 we're headed into Paies - the largest group ever attempted. Maicalany and Marco on the lead.  The Miconia crenata has crowded out the Ischaemum polystachyum and Palhinhaea cernua. Carpeting the cut in the Ridgeline. Melastoma malabathricum survives on the slope of the slot. 15:59 The class was strung out farther along the road than in any prior term.  16:24 [ covered earlier, but this ys a better plant now] The Cordyline fruticosa up at the northern end of the road has been cut down. There are plants left near the bridge.  16:24 The ...

Prior to the RipStik start at LRC I demonstrated that a true zero start was not physically possible. Friction with the wheels and the lack of sufficient slope prevent rolling from zero velocity. This demonstration helped me focus on low speed balance and was good preparation for the run.  A slight nudge was used and then split times were taken at 1.5, 3, 6, 9, 12, 15, 18, 21, 24, and 27 meters. No active swizzling was done prior to nine meters. Last spring marks were at every 1.5 meters, this term the 1.5 meter marks had been erased by rain. This necessitated the remarking of the three meter marks. This choice of a single 1.5 meter mark and then 3 meter marks with no acceleration until 9 meters worked better than expected.  The Desmos file was rebuilt with the expected distance marks, facilitating the data entry in the field. After class the spring term Desmos was duplicated and enhanced with the inclusion of acceleration values per segment. Note the first acceleration value i...

The walk opened with some sun dried Nostoc commune between the A building and the health center. I hadn't covered the nitrogen fixing capabilities of Nostoc, so I spent some time here. Then the class moved north to the line of breadfruit trees. The start was cold open built on my arrival at 3:30. Sweep in and go.  Davallia pectinata embedded in moss on a breadfruit trees. Davallia solida. A leafy liverwort mass on a breadfruit. The mass appears to be a way to retain water. The shape is essentially hemispherical. Leafy liverwort via telephoto. Up on a dead broken off branch of the penultimate breadfruit trees was sporophytic moss. Sphaerostephanos maemonensis underneath the Gardenia jasminoides. By 15:58 the class was headed west to the Dicranopteris linearis and the Palhinhaea cernua. Dicranopteris linearis. From here I headed to the Pterocarpus indica tree line, skipping the Blechnum or...
