G7 Week 02

Friday, September 15th

A period: Does not meet on Fridays

Homework: 

F & G period: Because A period had such difficulties creating a reliable legibility scale, Dr. Merritt proposed a simplified scale to both F & G periods. The simplified scale is included below. F & G periods tested two of their paper strips in both flat and carbonated water (15 minutes, measuring the water temperature every 5 minutes) and set them out to dry over the weekend.

5 – Perfectly legible. There is no visible evidence of bleeding, fading, blurriness, and/or dissolving. The handwriting appears entirely unchanged by its exposure to the liquid. All of the letters/numbers/symbols can still be effortlessly discerned (detected).

4 – Mostly legible. There is very little visible evidence of bleeding, fading, blurriness, and/or dissolving. The handwriting appears almost unchanged by its exposure to the liquid. Despite the visible alteration(s), however, all of the letters/numbers/symbols can still be discerned (detected) with very little effort.

3 – Legible, but with some effort. There is significant visible evidence of bleeding, fading, blurriness, and/or dissolving. The handwriting appears changed by its exposure to the liquid. Despite the visible alteration(s), however, all of the letters/numbers/symbols can still be discerned (detected) with some effort.

2 – Partially legible, but only with significant effort. There is a great deal of visible evidence of bleeding, fading, blurriness, and/or dissolving. The handwriting appears significantly changed by its exposure to the liquid. Although some features of the letters/numbers/symbols may still be discernible (detectable), other features cannot be discerned (detected) even with some effort.

1 – Perfectly illegible. There is complete visible evidence of bleeding, fading, blurriness, and/or dissolving. The handwriting appear entirely changed by its exposure to the liquid. In fact, no amount of effort by the observer could result knowing what letters/numbers/symbols were once written in the cell.

Homework: 

Thursday, September 14th

A period: Students were asked to test two different proposed legibility scales–each created by A period students–on another one of their four test strips. Students were asked to work in teams of 3-4 students while testing the effect of carbonated water on their test strips. Unfortunately, because of a general lack of focus and/or commitment, this class made very little progress in their goal. By the end of the period, this class was no closer to agreeing upon a legibility scale than at the start of the period. 😦

Homework: There is no science homework tonight.

F & G period: Today’s primary investigation task was to try and create a useful legibility scale with which to evaluate their written numbers after exposing them to the testing liquids. In the service of this task, students were asked to sacrifice one of their four testing matrix strips by exposing it to (flat/tap) water and observing and describing what happened to each of the ink colors. In A period, students were heard using words such as “fading,” “smudging,” “smearing,” and “bleeding.” Students were then asked to make use of these words in their revisions of the 5-point legibility scale shown to them at the beginning of the class period.

Homework: Students were asked to have a rough draft of a legibility scale written on a piece of lined (writing) paper by the beginning of their next class.

F period: Does not meet on Tuesdays.

G period: At the start of class, Dr. Merritt explained the use of the Classroom Science Binder. He then gave each student their own binder, which was labelled with a student number. Students that were absent on Monday were also asked to show Dr. M the nine items required for each day’s science lesson. All students were then asked to produce their bean, plastic Petri dish, and bean drawings. They were asked to label their papers and leave them on the side lab bench. 1 point was awarded for demonstrating the proper care of both the bean and Petri dish, which had both been in the students’ possession since last Thursday or Friday.

As a class, students then began preparing their Writing Utensil investigation by filling out a testing matrix with no less than six of the required class writing utensils.

Homework: There is no science homework tonight.

G period: Does not meet on Tuesdays.

Monday, September 11th – All periods

Today in science: Students had their first equipment check today, during which time they were asked to show Dr. M the nine items required for each day’s science lesson. Those students who could not show Dr. M all nine items were asked to try and produce them by next Monday, September 18, at the latest. After the equipment check, students began planning their first investigation, which Dr. Merritt supported with the help of this Google document.

Homework: There is only homework for students who have yet to complete their bean observation drawings. These drawings are due by the start of Tuesday’s (A & F period) or Wednesday’s (G period) science class.
