Newton's law from the back of a RipStik and friction

With Monday being a holiday, Newton's laws landed on Wednesday. I ran a "PowerPoint" presentation with slides attached to posts along the sidewalk, demonstrating each law by riding a RipStik while palming a ball.

Newton's laws


The classroom

Thursday I redeployed the model of having each student tackle a single friction variable. Again the grit teams found higher friction with finer sandpaper. Glass must have a roughness someone up where 1500 grit paper interacts with that roughness.


VanDamme and Elymore gather data on the effect of weight on the force of friction

John Phillip, Redsea, and Jayleen discuss results

Using Desmos to analyze the data

Darion and Tulpe work on their presentation

This term I brought along poster pad paper permitting the groups to prepare for their presentations.


Saichy and Kaiteie work on surface area versus the force of friction

Johsper presents the effect of weight

Dee-L also presented on the effect of weight

Melsina on the impact of weight on the force of friction

VanDamm presents findings with Elymore

Myreen also looked at the effect of weight

Darion and Tulpe present the effect of sandpaper grit on frictional force

AJ and Phillip on grit

Jayleen and Redsea

Austin and Justice

Kaiteie and Saichy

Yostrick and Rufus cover surface area

Science happens when results are communicated.

Plotting polar coordinates in Desmos and a vector addition demonstrator

Image
In an earlier post I noted that Desmos did not directly plot polar coordinates. Not only was I incorrect, but Desmos responded to my blog to correct me! Although I had at some point seen that one could define a function f(x)=3x+5 and then have Desmos calculate f(6), I had not absorbed how this might be used to plot polar coordinates. The above works beautifully . Realizing that I could effectively program Desmos, I applied this thinking to demonstrating how to add two vectors when given the magnitudes m and the direction angles theta. The graph calculates the i and j components for the two vectors and then adds the vectors, graphically displaying the result while also providing information on the magnitude and direction of the vector sum. m1 and theta1 are the magnitude and direction angle for one of the two vectors, m2 and theta2 are the magnitude and direction for the other vector. All four are dynamically interactive and can be changed. The diagram purports to illustra

Setting up a boxplot chart in Google Sheets with multiple boxplots on a single chart

Image
The  Google Statistics  add-on for Google Sheets can display multiple boxplots in a single chart. The key is the layout of the data. One column should be the variable by which the data is to be grouped, the other column should be the data to be box plotted. Set up the Statistics add-on with the data to be plotted as the variable, and the grouping column as the "by" variable. In this image I had deselected all but the boxplot option, the result was the appearance of the Moment, Standard errors, and Confidence intervals options. The default is apparently a 95% confidence interval for the mean. The result is multiple boxplots on a single chart with a common scale. The new tab that is created also quotes 95% confidence intervals for the mean. Note that as of 2018 the Google Statistics add-on cannot be found by search in the add-ons. In addition, as of May 2018 the add-on no longer verifies, possibly due to the add-on not having been updated since August 2017. One may ha

Traditional food dishes of Micronesia

Image
Clara, Jennette, and Joanie presented ground hard taro cooked in an umw, effectively a hot rock oven. Pohnpeian: rotama. Pingelapese: sero. Mwoakillese: rodma. Mortlockese: Amahd. Kosrae: rodoma. After cooking in an umw the rotama is pounded with the petiole of a palm frond. Rotama is made from hard or swamp taro, known as mwahng on Pohnpei, mweian on Pingalap, pula in Mortlockese, and pahsruhk on Kosrae. In traditional times on the outer islands the women had primary responsibility for tending the taro while the men handled fishing and climbing tasks. Joesen and Noeleen presented fermented breadfruit from the outer islands of Yap such as Woleai and Eauripik. The raw ingredients were actually brought in from Yap, Noeleen prepared the maare.  The leaf wrap is ti leaf - Cordyline fruticosa. Pauleen, Barnson, Trisha, Verginia, Con-ray, and Maylanda from Kitti, Pohnpei brought in mahi umw, koahpnoair koakihr, and uht sukusuk. Above is breadfruit umw, mahi umw, one o
