G7 Week 14

Last week in science!

Lesson 1 – Monday, December 7th

Today in science: Using the “Seed Germination Investigation – Planning” handout, students began setting up their Brassica rapa seed investigations. In addition to labelling and preparing their Petri dishes, some students added paper towel or soil to their dishes. NO seeds (or water) were added to the Petri dishes (C period will do this on Tuesday, while H period will do this on Wednesday). With any remaining time in the lesson, students had a chance to begin working on Chapter 1 (pp. 1-4) of the new “Food For Plants” packet, which is homework for those who did not finish during class.

Homework: Students have been asked to complete–to the best of their ability–Chapter 1 of the new “Food For Plants” packet. This means providing coherent, thoughtful answers to the questions found on pages 1-4. IMPORTANT NOTE TO STUDENTS: Pages 3 & 4 refer to work you have done in the “Power Plant Packet.” Don’t worry, you have NOT done the Power Plant Packet this year, but you do NOT have to have done that packet in order to provide thoughtful answers to the questions asked of you in this, the Food For Plants, packet.

Lesson 2 – Tues-Wed, December 8-9th

Today in science: Students were given guidance in setting up their Brassica rapa seed investigations today. While most students were able to get their Petri dishes prepared during this lesson, some students were unable to put seeds into their dishes before leaving class (NOTE: many H period students missed this lesson because of their participation in the TASIS holiday video recording). During the lesson, Dr. M asked students to record all necessary set-up data (e.g., air temperature, volume of water, mass of soil, etc.) on their “Seed Germination Investigation – Planning” handout.

Homework: Only students who did not complete Chapter 1 of their new “Food For Plants” packet have homework to do tonight.

Lesson 3 – Wed-Thurs, December 9-10th

Today in science: Although some students still needed to initiate their seed experiment, for many students today counted as “Day 1” of their investigation, which meant the need for data collection. To help show students what data needed collecting, Dr. M asked students to create two separate pages in their Lab Notebooks with room for two data tables and reserved (empty/open) areas for making drawings. These two pages can be viewed in the Notes Portal. Students then spent the remaining time collecting data from their investigation (or, in some cases, finishing setting the experiment up).

Homework: Students have been asked to complete–to the best of their ability–Chapter 2 of the new “Food For Plants” packet. This means providing coherent, thoughtful answers to the questions found on pages 5-8. If you find yourself in need of definitions for any seed-related vocabulary words, consider visiting the SCIENCEsEDiment Glossary pages or some of your class notes.

Lesson 4 – Friday, December 11th

Today in science: Students were asked to turn in their homework at the start of the lesson (“Food For Plants” packets, Chapter 2). Then, regardless as to whether their seed germination experiment was started on Tuesday or Wednesday, students spent today collecting data and recording it in their Lab Notebook. In addition to their seed germination data (recorded as percents, drawings, photographs, and length measurements), students were also asked to collect air temperature data and to record any water/fertilizer added to their Petri dish(es) during today’s lesson. Students were also asked to record any general observations pertaining to the non-seed elements of their investigation (e.g., water, paper, soil, Petri dish, etc.). To help students label their drawings/photographs accurately, Dr. M showing students three labelled seed(ling) diagrams on the whiteboard.

Homework: There is no science homework this weekend.
