The Hot Wheels variant of this laboratory is functionally more complex and takes much longer to set up. There are many moving pieces. And the results were surprisingly inconsistent. The folding chairs approach was used to mount the ramps but with the chairs on the sinks instead of the table to gain more height. The center table was set up with a 174 cm speed trap to measure velocity. Jaysleen opens the new box of Hot Wheels cars. A timing start mark was made on the ramp where the height was effectively zero. The track as viewed from the front. This was 8:50 AM and data recording had not yet begun. The track took that long to set up - from a start at 7:45. The track plus the board notes and the demonstration runs.  The board notes as recorded after class. DeAnne and Alisha gathering data.  As more students arrived, they decided to set up a second dual track. Tikikos working on fixing...

As in prior terms, this class featured a silent start. Not a word was spoken. The above diagram was put on the board. Then rulers and marbles were distributed. No explanation was given. No directions. For the first 20 minutes nothing was said. The students worked out that they were to run through the above scenarios. The silent start means that there isn't the opportunity to gather predictions. Eytriann and Mor-Jacinta engaged with the experiment Eytriann and Lidy-Loreen Every student had a rulers and ten or more marbles One in, one out Stacy, one in fast. One out fast, plus a second slower outbound marble Emensio, Tikikos, Kyle, and McGievens After everyone had generally exhausted the scenarios, the results were pulled together. Leading into the conservation of momentum

En Neiratancy of Chuuk spoke about Psidium guajava and its use in treating diarrhea. Jenry-Thor presented a Chuukese treatment for heartburn. A single all green frondlet from a coconut palm is fashioned into a necklace and worn around the neck. Action as a distance of some sort.  Geneva brought a commercial cultivar of Ixora and provided a treatment that may have actually been for Ixora casei.  Keisha brought in Senna alata and spoke on its use as a topical treatment for sensen a skin disease caused by a fungus which causes white spots on the skin. She also said the plant can cure kilin kutuwa, ringworm, a type of fungal skin disease that results in round, rough, and very itchy rashes. Senna alata, tuhke en kilinwai, is widely known for being antifungal when used topically. Anastasia of Pehleng, Kitti, brought in kadireng (Ocimum tenuiflorum) and explained the use of kadireng to treat itchiness of the...

This term the empty courtyard of the future student union beckoned.  Gear was RipStik, tape measure, timer, and foam beads. Form beads proved sufficient for seeing the distance marks while riding. The wind funnels through the building which displaced a couple foam beads. 24 meters was the maximum distance. 27 meters is not quite possible - the wall is out around 26.7 meters. The lap times were seven, not eight, which means a timing mark was missed. Looking at the lap times the time from 3 to 6 was long at 5.537 seconds. That suggested that six was missed and the 9.317 second time is out at 9 meters. Bear in mind that the start was intentionally at one meter and the starting velocity was 0 meters per second. The intent was to force the existence of a y-intercept. Future runs might want to skip the three meter mark split time and mark the first lap time at 6 meters. The start of this run was unstable.
