Today in science: The main themes for today’s lesson were “magnification” and “observation.” At the start of class, students were asked to create another wet mount slide of the letter “e.” In doing so, students were expect to following the protocol given to them in a previous lesson. This time, students were asked to draw what they saw underneath the binocular microscope at both 20x and 40x. Both drawings not only had to include the magnification used within the label of the drawing, but they also had to be done on a new page of the lab notebook. At the end of the period, Dr. M evaluated the wet mount slides produced by each student, as well as students’ ability to return their dissection kits to him in the appropriate condition.
Homework: Dr. M has asked students to continue preparing for an upcoming quiz about the names of the parts of the monocular light microscope. To begin learning the names of the parts of this instrument, Dr. M has provided students with a Google Slides tutorial and printable handouts containing both labelled and unlabelled monocular light microscopes. Students will complete the quiz on Thursday, 25 October.
Tuesday-Wednesday, October 23rd-24th
Today in science: The main themes for today’s lesson were “technique” and “observation.” At the start of class, students were asked to update the table of contents of their lab notebooks with yesterday’s work. Students were then asked to prepare four wet mount slides with specimens of their choice–it was noted by Dr. M, however, that the four selected specimens had to be 1) flat, 2) somewhat transparent, and 3) smaller, in terms of area, than the area of the glass coverslip. Students then had the remaining class time to demonstrate their slide-making skills to Dr. M, who gave advice and offered verbal assessments of the students’ wet mount slides. Students were asked to make 20x or 40x drawings of each of their four specimens.
Homework: In addition to the quiz (see Monday’s homework entry above), students have until Friday to finish their flower and ping pong ball drawings in their Lab Notebooks. Dr. M has told students that he will be evaluating these two stippling exercises this coming weekend. Students must use the stippling technique–or another technique if suggested by Dr. M–when doing these drawings.
Thursday, October 25th
Today in science: The main themes for today’s lesson were “technique” and “observation.” At the start of class, students were asked to prepare a wet mount slide of a single Elodea leaf. Students were not only asked to make both 20x and 40x drawings of this specimen, but they were also asked to take pictures of their specimen at each magnification so that they could then use the photos to finish their two specimen drawings outside of class. Many students also had the opportunity to see 100x and 400x magnification of the leaf prepared by one of their classmates for the monocular microscope.
Homework: There is no science homework during Academic Travel.
