G7 Week 13

Friday, December 2nd – F & H periods (Day 60)

Today in science: F & H period students submitted the results of their Word Mining assignment for “Seed(s),” and then helped Dr. M and Dr. Kelly create important sentences about seed(s). Students recorded these sentences on a handout provided by Dr. Merritt.

Homework: All science students–A, F, & H period–have all been asked to complete Investigation No.’s 4 & 5 by the start of class on Monday, Dec. 5th. This means that all photographs and/or drawings must be put into the lab notebook and cropped, formatted, titled, and labelled according to the rules presented in class by Dr. M last week.

Thursday, December 1st – All periods (Day 59)

Today in science: F & H period students had time to work on one of three assignments: 1) complete Investigation #4, 2) complete Investigation #5, and 3) begin tonight’s homework assignment, which involves searching for the word “seed” (or “seeds”) in the pages of the Power Plant Packet. For details regarding this last assignment, please see below. A period students submitted the results of their Word Mining assignment for “Seed(s),” and then helped Dr. M and Dr. Kelly  create important sentences about seed(s). Students recorded these sentences on a handout provided by Dr. Merritt.

Homework: 

A, F, & H period science students have all been asked to complete Investigation No.’s 4 & 5 by the start of class on Monday, Dec. 5th. This means that all photographs and/or drawings must be put into the lab notebook and cropped, formatted, titled, and labelled according to the rules presented in class by Dr. M last week.

F & H period students have been asked to search the entire Power Plant Packet and find EVERY instance in which the word “seed” (or “seeds”) is used. When found, students have been asked to highlight the entire sentence the word. Students were also encouraged to mark the pages on which the word “seed/seeds” appears with small sticky notes (or, better yet, plastic reading tabs) OR to use the back (blank) page of the packet as an index, which lists the actual page numbers on which the word appears.

Wednesday, November 30th – A & H period (Day 58)

Today in science: After some guidance from Dr. M and a brief class discussion about embryos, A & H period students spent the entire class dissecting Kabocha squash seeds (Cucurbita maxima) and photographing the embryo (and cotyledons). Students also saw a time lapse video of squash seed germination, which helped them to see what the structures seen inside of the seed will become after seed gemination occurs.

Homework: 

H period students have been asked to print any good photos of the pumpkin seed embryo and then bring the printed photographs to their next class. If NO printer is available, then students need to create a drawing (or drawings) of the photograph (or photographs) by hand, which they will put into their lab notebook during the next science class.

Tuesday, November 29th – A & F period (Day 57)

Today in science: While a few students still needed time to glue photographs of their B. rapa embryos into their lab notebooks, most students spent the period dissecting Kabocha squash seeds (Cucurbita maxima) in search of an embryo. After a couple of attempts and some guidance from Dr. M, most students found the embryo and then photographed it. In class, Dr. M suggested that students try capturing the following images:

Whole embryo (0x), Split embryo (0x), Nearly split embryo (0x), Testa (ox), Radicle (20x), Hypocotyl (20-40x), the vein-like pattern visible in the cotyledons (0-20x)

F period students were asked to watch an excellent time lapse video squash seed germination so as to be able to see what the structures seen inside of the seed will become after gemination occurs.

Homework: Students have been asked to print any good photos of the pumpkin seed embryo and then bring the printed photographs to their next class. If NO printer is available, then students need to create a drawing (or drawings) of the photograph (or photographs) by hand, which they will put into their lab notebook during the next science class.

Monday, November 28th – All periods (Day 56)

Today in science: Students were asked to produce their computer printed (or hand-drawn) photographs of the B. rapa embryos from last week and fix them into their lab notebooks. Toward this end, Dr. Merritt gave students access to extensive instructions explaining how to properly print, format, label, and title the images placed into the lab notebook. With the time remaining, some students began dissecting Kabocha squash seeds (Cucurbita maxima) in search of an embryo.

Homework: All A, F, & H period students have been asked to have complete Investigation #4 by the start of their next science class. This means fixing all photographs in the lab notebook with glue and formatting, titling, and labelling them appropriately.
