Monday, February 10th
Today in science: With over half of most of the science classes involved in International Week assembly rehearsals, adjustments were made to today’s lesson plan so as not to have to repeat the same lesson again on Tuesday/Wednesday. Those present in class thus returned Sir David Attenborough’s The Private Life of Plants, which presented and explained the unique adaptations of plants to their environment(s).
Homework: There is no science homework tonight.
Tuesday, February 11th (no H period)
Today in science: Returning to our Brassica rapa seed experiments, students identified their independent variable and learned new phrasing for their dependent variable (e.g., the germination success of the seeds, as measured by the “percent germinated”). We then spent the remaining part of the lesson giving our undivided attention to the following question by means of a class discussion: What do seeds need to germinate successfully? Our final answer to this question has been recorded in the Notes Portal.
Homework: There is no science homework tonight.

H & B period: After receiving their graded Identifying Variables quiz, students were asked to return their attention to their Brassica rapa seed experiments. Students not only identified their independent variable, but they also learned new phrasing for their dependent variable (e.g., the germination success of the seeds, as measured by the “percent germinated”). We then spent the remaining part of the lesson giving our undivided attention to the following question by means of a class discussion: What do seeds need to germinate successfully? Our final answer to this question has been recorded in the Notes Portal.
Homework (H & B period): There is no science homework tonight
C period: After receiving their graded Identifying Variables quiz, students were asked to recall the 5 ‘factors’ affecting seed germination discussed at the end of yesterday’s lesson. After the discussion, students were then asked to design and create three different data tables for their upcoming seed experiment.
- Each data table will be used to record whether or not one of the key controlling variables–water, oxygen gas, and temperature–was, in fact, controlled during the experiment.
- Water will be measured in “mL” units.
- Temperature will be measured in “degrees C” units)
- Oxygen gas will be measured in “%”
- The experiment will require data collection for 7 consecutive days.
- The data tables should record what happens in EACH Petri dish used during the experiment (e.g., Petri dish A, Petri dish B).
- All data tables should be completed on graphing paper.
Homework (C period): C period students must have their 3 controlling variable data tables completed by the start of Friday’s class.
Thursday, February 13th (no C period)
H period: Students were asked to recall as many of the ‘factors’ affecting seed germination as they could remember from their last lesson. After some great debate(s) and intelligent discussion, Dr. M presented students with scientists’ current understanding of the factors affecting seed germination. Students were asked to write these factors down in their Lab Notebooks, but these notes have also been recorded in the Notes Portal.
Homework (H period): There is no H period science homework tonight.
B period: Students were asked to recall the 5 ‘factors’ affecting seed germination discussed at the end of yesterday’s lesson. After a class discussion of these variables, students were asked to design and create a data table for “water” that could be used in their upcoming seed experiment. This exercise led into a description of the homework for Monday (see below).
Homework (B period): After seeing an example created in class, students have been asked to create three data tables on the SAME side of a SINGLE sheet of graph paper. Each data table will record the data related to one of the three controlling variables we’ve identified for our seed experiment: WATER (measured in “mL”), OXYGEN GAS (measured in “%), and TEMPERATURE (measured in “degrees C”). Students should use a ruler when creating the rows and columns of their three data tables.
Friday, February 14th (no B period)
Today in science: After having students put their most recent quizzes in their Classroom Science Binder and checking in their homework (drafts of the 3 controlling variables data tables), Dr. M spent some time talking about the rules of making good scientific data tables. Students were then asked to revise their tables, as well as create a fourth table (similar to the controlling variables tables, but this time for the dependent variable), and glue them into their Lab Notebooks in preparation for next week’s seed experiment (see Homework description below).
Homework: By the start of Monday’s lesson, those students who were in class on Friday were asked to complete their final copies of their 4 revised data tables for their upcoming seed experiment. These 4 tables were either completed, or mostly completed, in class on Friday, but some students needed to take their materials home in order to complete the full task. If possible, the 4 data tables should all oriented in the same direction and GLUED (not stapled or taped) onto a single page of the Lab Notebook. If this is not possible, then students have been told to put their 3 controlling variable data tables on one page, while putting their newest (dependent variable) data table on a second page.
