G7 Week 14

Last week in science!

Monday, December 2 – Day 21

Today in science: Students received the Flower Packet at the start of today’s lesson. Dr. M asked students to make page 2 of the packet look like the example he put on the whiteboard, including adding yellow and green coloring to show the actual colors of the real flower parts. Students then had time to measure the height of their plants, record their data in their height table, pollinate all newly opened flowers, and observe–and photograph–any successfully pollinated (i.e., now pregnant!) flowers.

Homework: C period students have been asked to add the following flower-related vocabulary words to their Lab Notebooks followed by the definitions from the SCIENCEsEDiment glossary: petal, sepal, nectary, receptacle, stamen, pistil, flower buds, and flowers.

Tuesday, December 3 – Day 22

Today in science: After recording the definitions of all 15 of the flower-related vocabulary words in their Lab Notebook, students were asked to complete the “Knowing Flowers – Functions” page of their Flower Packet. They were then asked to prepare a new entry in their Lab Notebook for tomorrow’s Flower Dissection investigation.

Homework: During class, students were asked to be sure they have finished recording the definitions of all 15 of the flower-related vocabulary words in their Lab Notebook. These words include: anther, filament, flower, flower buds, nectary, ovary, ovule, petal, pistil, pollen grains, receptacle, sepal, stigma, style, stamen.

Wednesday, December 4 – Day 23

H period: After recording the definitions of all 15 of the flower-related vocabulary words in their Lab Notebook, students were asked to complete the “Knowing Flowers – Functions” page of their Flower Packet. They were then asked to prepare a new entry in their Lab Notebook for tomorrow’s Flower Dissection investigation.

Homework (H period): During class, students were asked to be sure they have finished recording the definitions of all 15 of the flower-related vocabulary words in their Lab Notebook. These words include: anther, filament, flower, flower buds, nectary, ovary, ovule, petal, pistil, pollen grains, receptacle, sepal, stigma, style, stamen.

B & C period: Students learned how to do a flower dissection today, which first involved preparing a page in the Lab Notebook for a new investigation. After removing one newly opened Brassica rapa flowers from one of their plants (the ultimate sacrifice!) students were asked to carefully separate the flower–with a sort of ‘peeling’ technique–into the following parts: sepals (4), petals (4), stamens (4-6), and the pistil structure (1). Students were asked to neatly arrange the parts in the four pre-labelled circles already drawn in their Lab Notebook, and then to use a special clear tape to permanently fasten the groups of parts onto the page. With the remaining time, students could examine other flowers under the microscope and/or work further in their Flower Packets.

Homework (B & C period): There is no science homework tonight.

Thursday, December 5 – Day 24

H period: Students learned how to do a flower dissection today, which first involved preparing a page in the Lab Notebook for a new investigation. After removing one newly opened Brassica rapa flowers from one of their plants (the ultimate sacrifice!) students were asked to carefully separate the flower–with a sort of ‘peeling’ technique–into the following parts: sepals (4), petals (4), stamens (4-6), and the pistil structure (1).

With the remaining time, students could examine other flowers under the microscope and/or work further in their Flower Packets.

Homework (H period): There is no science homework tonight.

B period: Students were asked to 1) measure the height of their plants and record the data in their Lab Notebooks, 2) pollinate any newly opened flowers on their plants, 3) complete the “Knowing Flowers – Functions” page of their Flower Packet (and have it checked/stamped by Dr. M), and 4) complete the 2-page “Practice Flower Quiz” found at the back of their Flower Packet (and have it checked/stamped by Dr. M). Finally Dr. M asked students to begin collecting photographs for their Life of a Flower project, which aims to capture 10 photographs that illustrate the life of a Brassica rapa flower from its earliest, youngest stage as a flower bud (or unopened flower) to its oldest, most mature stage as a fruit (or seed pod).

Homework (B period): Students should begin preparing for next Thursday’s quiz (12 Dec), which will cover all of the flower structures and their functions discussed in class during the past week. For extra practice and preparation, Dr. M has made the following resources available for printing and use outside of class: Flower Structures (plus answer key) and Flower Functions (plus answer key).

Friday, December 6 – Day 25
