G7 Week 03

Friday, September 22nd

A period: Does not meet on Fridays.

F period: At the start of the period, students the testing strips they prepared at home. They then tested their writing utensils in the three remaining liquids: ethanol alcohol (ETOH), a weak acid (HCl), and a weak base (NaOH). On a sheet of graph paper, students then began preparing the data table that will house the final results of this week’s writing utensil investigation.

Homework: There is no science homework this weekend.

G period: At the start of the period, Dr. Merritt did an Equipment Check (#2) and then asked students to present the test strips they prepared at home. Students then tested their writing utensils in the three remaining liquids: ethanol alcohol (ETOH), a weak acid (HCl), and a weak base (NaOH). On a sheet of graph paper, students then began preparing the data table that will house the final results of this week’s writing utensil investigation.

Homework: There is no science homework this weekend.

Thursday, September 21st

A period: After inserting a new Table of Contents into their Classroom Science Binders, students inserted, catalogued, and numbered their first binder assignment. Students then began testing their writing utensils in five liquids: water (tap), sparking water (CO2), ethanol alcohol (ETOH), a weak acid (HCl), and a weak base (NaOH). Before the end of the period, Dr. Merritt also did an Equipment Check (#2).

Homework: Students have been asked to use their 2-3 remaining test strips to test their writing utensils against some liquids commonly found in/around the home kitchen. Some suggestions include milk (cow, soy, coconut, almond, etc.), tea (hot or cold), Coca Cola, Sprite, Fanta, coffee, vinegar, oil, soy sauce, fruit juice, wine, etc.). Students should remember to keep their paper strip in the test liquid for the same length of time as the tests performed in class (approx. 15 minutes), but also to be careful if/when testing hot liquids. Students should bring dried test strips to their next science class.

F period: After inserting a new Table of Contents into their Classroom Science Binders, students inserted, catalogued, and numbered their first binder assignment. Students then finished preparing their remaining testing strips. Before the end of the period, Dr. Merritt also did an Equipment Check (#2).

Wednesday, September 20th

A period: Because this class had such difficulties creating a reliable legibility scale last week, Dr. Merritt proposed a simplified scale. The simplified scale can be seen on last week’s This week in science! page. Students then completed a second testing matrix so that they possess six test strips–one for each of the remaining test liquids (tap water, carbonated water, juice, weak acid, weak base, alcohol).

Homework: Because all students created and prepared their six test strips in class, there is no science homework tonight.

F period: Does not meet on Wednesdays.

G period: Dr. Merritt asked students to begin setting up their lab/field notebooks today. To do so, he asked them to 1) cut/trim and glue three pages of a (blank) table of contents, 2) number the remaining pages in the notebook in the outside, lower corner of each page, and 3) copy the “12 General Rules” onto Page 0. Those students who finished with time still left in class were asked to begin reassembling the Testing Matrix used in last week’s flat and carbonated water trials of their writing utensils.

Homework: Students were asked to complete a second testing matrix so that they possess at least four more test strips–one for each of the remaining test liquids (juice, weak acid, weak base, alcohol).

Tuesday, September 19th

A & F period: Dr. Merritt asked students to begin setting up their lab/field notebooks today. To do so, he asked them to 1) cut/trim and glue three pages of a (blank) table of contents, 2) number the remaining pages in the notebook in the outside, lower corner of each page, and 3) copy the “12 General Rules” onto Page 0. Those students who finished with time still left in class were asked to begin reassembling the Testing Matrix used in last week’s flat and carbonated water trials of their writing utensils.

Homework: Any student not finishing the three tasks assigned in class should complete them before the beginning of their next science class.

G period: Does not meet on Tuesdays.

Monday, September 18th – No classes today

Today in science: There were no science classes today due to the MS Founder’s Day class hikes.

Homework: —
