Monday, November 5th
Today in science: The main theme for today’s lesson were “levels of organization.” On a half-sheet of paper at the start of class, Dr. M asked students to recreate a diagram seen in past lessons to the best of their ability. The diagram shows what we’ve called in class the ‘levels’ or organization. Today’s new additions to the diagram was to label which parts of the diagram scientists consider to be non-living (atoms, molecules) and which they consider living (cells, tissues, organs, organ systems, organisms). Using the SCIENCEseDIMENT Glossary pages, students were then asked to write the definitions of the 7 vocabulary words found in the diagram on a piece of lined paper.
Homework: Students have been asked to finish writing the definitions of the 7 vocabulary words given to them by Dr. M during Monday’s class. The 7 words are: ATOMS, MOLECULES, CELLS, TISSUES, ORGANS, ORGANS SYSTEMS, ORGANISMS. The definitions needed for all 7 of these vocabulary words can be found on the Glossary pages.
Tuesday, November 6th
Today in science: The main themes for today’s lesson were “technique” and “cells.” Dr. M first mentioned to students that he noticed that many student lab notebooks were still missing their 20x and 40x Elodea leaf drawings (the ones observed with the binocular microscopes). After spending time explaining and demonstrating some of the most important skills and rules needed when using the monocular microscopes, in the remaining time Dr. M then asked students to make (yet) another wet mount slide of an Elodea leaf for practice in using the low, medium, and high power lenses/objectives of the monocular microscopes.
Homework: There is no science homework tonight, but some students have taken their lab notebook home so as to complete their two Elodea leaf drawings.
Wednesday-Thursday, November 7-8th
Today in science: The main themes for this 2-day series of lessons were “technique” and “cells.” Students were asked to make 5 drawings in their Lab Notebooks from the wet mount slides they prepared in class:
Elodea leaf (20x or 40x)
Elodea leaf (40x or 100x)
Banana cells (40x)
Banana cells (100x)
Banana cells (400x)
For each slide, students were asked to take photographs to help them complete their drawings at home.
Homework: There are two homework tasks all students must complete before Monday’s science class:
1) Students have been asked to finish making their five drawings (see above) in their Lab Notebook.
2) Dr. M has asked to see the BEST photo students took during their banana cell investigation. It does not matter if it is the 40x, 100x, or 400x photo, whichever photo has the most clarity and shows the most interesting details is the one to choose and send to him. Please follow these simple instructions when sending your email to Dr. M…of course, you need to replace the question marks below with your information:
Student ??A, banana cell, ???x
Dear Dr. M. This is a picture of my iodine-stained banana cells at ???x magnification. Yours in science, [Your first & last name]
Don’t forget to include your photo in either the email text OR as an attachment.
