G7 Week 04 – S2

Last week in science!

Monday, February 17th

Today in science: Upon entering in the lab, each student was given a written procedure for their Brassica rapa seed germination experiment. Students then had 40 minutes to follow steps 1-7 of the procedure, which means that those present in the lesson (hopefully!) left the classroom with 2 or 3 well-watered Petri dishes left in the experiment area at the back of the room. Upon exiting the lab, Dr. M asked each student to leave their Lab Notebook with him so that he could check the weekend homework, which involved the creation of data tables for use in the seed experiment.

Homework: There is no science homework tonight.

Tuesday, February 18th (no H period)

Today in science: Although B & C periods were at slightly different places, by the end of their lesson all students present in the lesson had (fingers crossed!) completed the following tasks…

  1. Glue the printed ‘Procedure’ onto the page on which it was taped by your teacher.
  2. If asked by your teacher, revise your data tables before cutting and gluing them into the stamped page of your Lab Notebook.
  3. B period only: Make a new 7-day table for the independent variable, Table 4 (“Germination success (%)”), cut it and glue it  into the Lab Notebook.
  4. Record “Day 1” data for all three controlling variables (temp, water, oxygen) and the independent variable (% germination success).
  5. Record “Daily observations” including drawings of ‘typical’ (or representative) seeds from each Petri dish.
  6. Take photographs that provide additional visual evidence of both germinating and non-germinating seeds.

Homework: The only B & C period students to have homework tonight are those who found an orange sticky note on the cover of their Lab Notebooks today saying to update their table of contents (TOC) and/or add page numbers.

Wednesday, February 19th (no C period – special schedule)

B & H periods: By the end of their lesson all B & H period students present in the lesson had (fingers crossed!) completed the following tasks…

  1. Record “Day 2” data for all three controlling variables (temp, water, oxygen) and the independent variable (% germination success).
  2. Record “Daily observations” including drawings of ‘typical’ (or representative) seeds from each Petri dish.
  3. Take photographs that provide additional visual evidence of both germinating and non-germinating seeds.

Homework: The only H period students to have homework tonight are those who found an orange sticky note on the cover of their Lab Notebooks today saying to update their table of contents (TOC) and/or add page numbers.

Thursday, February 20th (no C period)

B & H period: By the end of their lesson all B & H period students present in the lesson had (fingers crossed!) completed the following tasks…

  1. Record “Day 3” data for all three controlling variables (temp, water, oxygen) and the independent variable (% germination success).
  2. Record “Daily observations” including drawings of ‘typical’ (or representative) seeds from each Petri dish.
  3. Take photographs that provide additional visual evidence of both germinating and non-germinating seeds.
  4. Many B period students were also asked to write a complete “Materials” list for someone who might wish to repeat their experiment.
  5. While some students were asked to stop their experiments and empty their Petri dishes, other students were asked to take their Petri dishes home for the weekend so they could continue their seed experiments for additional days.

Homework: There is no science homework tonight, but some B period students are expected to continue their seed experiments at home for the next 2-3 days.

Friday, February 21st (no B period)

C & H period: By the end of their lesson all C & H period students present in the lesson had (fingers crossed!) completed the following tasks…

  1. Record “Day 4” data for all three controlling variables (temp, water, oxygen) and the independent variable (% germination success).
  2. Record “Daily observations” including drawings of ‘typical’ (or representative) seeds from each Petri dish.
  3. Take photographs that provide additional visual evidence of both germinating and non-germinating seeds.
  4. Some students were also asked to write a complete “Materials” list for someone who might wish to repeat their experiment.
  5. While some students were asked to stop their experiments and empty their Petri dishes, other students were asked to take their Petri dishes home for the weekend so they could continue their seed experiments for additional days.
