Tuesday – Friday, January 10th – 13th
Today in science: A, F, & H period students mined Episode 1 (“Travelling”) of the BBC’s The Private Life of Plants video series for new statements about “seeds.” Here is a running list of the statements that we extracted from the episode:
1. Seeds are the next (or new) generation of plants.
2. Seeds are a miracle of packaging.
3. Seeds have genetic instructions–in the form of DNA–to make new plants.
4. Seeds contain DNA.
5. Seeds can be carried by the wind because of their relatively small size and mass.
6. Seeds can fly with the help of parachute-like structures.
7. Seeds can fly with the help of glider-like structures.
8. Seeds can fly with the help of helicopter-like structures.
9. Seeds can fly with the help of water pressure OR Seeds can be launched by water pressure.
10. Some seeds (e.g., tropical sea beans) are surrounded by a protective covering (pouch) that allows them to float unharmed by water–even salt water!–for as long as a year.
11. Some seeds will not germinate in cold climates.
12. Some seeds have hook-like or spike-like structures that can help them travel on animals (e.g., fur, hooves, pants, boots).
13. Some seeds produce edible rewards outside of the seed coat for animals to eat.
14. Some seeds have a non-digestible seed coat that protects them from being digested in the stomach (or crops) of animals.
15. Some seeds cannot germinate in shade; they require sunlight.
16. Some seeds can germinate in shade; they do not require sunlight.
17. Seeds are nutritious; they contain energy and minerals.
18. In addition to the seed coat itself, some seeds (e.g., brazil nuts) are extremely well protected by a hard, external structure–for example, some sort of container, capsule, or shell.
19. Some seeds can remain dormant (a sort of hibernation) without germinating for many years.
20. Seeds can benefit from the minerals naturally found in soil, animal waste (feces/dung), and ash (from fires).
21. One type of seed–a magnolia seed found in Japan–germinated after 2000 years of dormancy (hibernation).
22. Seeds can travel through space AND across time.
Homework: All A, F, and H period students have been asked to print one copy of their entire Google Document by Monday, January 16th. Do not print a double-sided document. Print only a single-sided document. The best document to print is the one titled “Copy of…”, but if you never created this document with Dr. Merritt before the Winter Vacation then print the only Google Document you have (the one with your student number in the title). This document should contain the 22 new sentences mined from the BBC’s Private Life of Plants video (see below), plus all of the textbooks we mined in class before vacation.
Monday, January 9th – All periods
Today in science: Students provided Dr. Merritt with some information regarding their holiday travel, a personal New Year’s resolution, and their confidence (or lack of!) in Dr. M’s ability to fulfill his new ‘walking’ resolution. They also provided Dr. M with a single word or short phrase that they think will represent the year 2017. Here are the results:
A period – atrocious, interesting, decent, tough, awesome!!!, 2016, fantastic, awesome, majority, weird as always, great, fantastic, new, Trumpagedon
F period – exciting/successful, slow, happy, mystery/sad, dangerous, calm, very happy, moving on, death, amazing, a roller coaster!
G period -happy/crazy, different, fantastic, fresh, 57, fun/successful, changing, extravagant, fun/annoying/fresh, exciting, more chaotic, hopefully fun/great!!!, trying
Homework: There is no science homework tonight.
