G6 Week 13

Friday, December 1st

Today in science: After observing some of the Petri dishes set up by a few students on Thursday with drops of salt water and left overnight to dry/evaporate, Dr. Merritt asked students to design some 24-hour investigations involving salt water and evaporation. In their lab notebooks, students were asked to record their research questions. For the rest of the class period, students set up their investigations, which they will then check on Monday.

Homework: There is no science homework tonight.

Thursday, November 30th

Today in science: At the start of class, we discussed the notion of the ‘ideal’ salt crystal. In other words, the one salt crystal in each students’ sample that best represents all of the other crystals. Dr. Merritt also introduced a drawing technique called “stippling,” which is commonly used by illustrators to create greater depth and dimensionality in scientific drawings. Students then had time to search for, identify/select, and draw their ‘ideal’ salt crystal in their lab notebook.

Homework: There is no science homework tonight.

Wednesday, November 29th

Today in science: Dr. Merritt collected the revised draft of the line graphs at the start of the class period. As a class, we examined all of the graphs and Dr. Merritt pointed out both strengths and areas in need of (further) improvement. Students then had time to examine salt crystals under the stereo (dissecting) microscopes.

Homework: There is no science homework tonight.

Tuesday, November 28th

Today in science: H period does not meet on Tuesdays.

Homework: Students need to complete the revised line graph that we began in class today before their next class (Wednesday).

Monday, November 27th

Today in science: As a class, we examined last week’s line graphs produced by nearly all of the H period students. During this examination, Dr. Merritt pointed out both strengths and areas in need of improvement. With this conversation in mind, Dr. Merritt asked students to revise (redo) their line graphs on a new piece of graphing paper. Students can see all of the data that needs to be put into the new-and-improved line graph in this linked Google Document. As a class, we agreed that the colors for the lines would be as follows:

Black = Personal/Individual results
Red = H period results (class average)
Green = C period results (class average)
Blue =  E period results (class average)

Homework: Students need to complete the revised line graph that we began in class today before their next class (Wednesday).
