G7 Week 07 – S2

Friday, March 16th

A period: A period science class does not meet on Fridays.

F & G period: After taking the seed germination quiz, which was given through a Google Form at the start of class, F & G period students were asked to prepare 1-2 pages of their Lab Notebooks for the data that needs to collected during next week’s seed germination experiment. Examples of the data tables showed on the board in class can be seen HERE.

Homework: F & G period students have been asked to print ONE copy of their Seed Germination document and bring it to MONDAY’s science class. Without a printed copy of this document, students will NOT be allowed to begin their seed germination investigation, which is planned for all classes MONDAY, March 19. Even though this document contains colors (yellow, pink, green), this document does NOT need to be printed in color.

A period: After taking the seed germination quiz, which was given through a Google Form at the start of class, A period students were asked to prepare 1-2 pages of their Lab Notebooks for the data that needs to collected during next week’s seed germination experiment.

Homework: A period students have been asked to print ONE copy of their Seed Germination document and bring it to MONDAY’s science class. Without a printed copy of this document, students will NOT be allowed to begin their seed germination investigation, which is planned for all classes MONDAY, March 19. Even though this document contains colors (yellow, pink, green), this document does NOT need to be printed in color.

F & G period: Students continued making improvements and additions to their Seed Germination procedure. Here is a short list of most of the things Dr. Merritt asked F & G period students to attend to during class:

1) Add a “Seed Sample Size” section below the “Procedure” section. This section contained written answers to the following questions: 1) HOW MANY (or what percent) of your total number of harvested seeds will you attempt to germinate in your upcoming experiment? and 2) WHY do you believe the number of seeds you will attempt to germinate is a good number, scientifically speaking?

2) Add a “Seed Selection Protocol” section below the “Seed Sample Size” section. This section contained written answers to the following questions: 1) HOW will you select the seeds you will attempt to germinate in your experiment? and 2) WHY do you believe your seed selection process is a good selection process, scientifically speaking?

3) Make sure that EVERY material appears SOMEWHERE in your procedure, but know that it’s OK if a single material appears in multiple steps of the procedure.

Homework: F & G period students have a seed germination quiz on Friday.

Wednesday, March 14th

Today in science: G period students followed the lesson described in the Tuesday, March 13th entry (see below). A period students continued making improvements and additions to their Seed Germination procedure. Here is a short list of the things Dr. Merritt asked A period students to attend to during class:

1) Add a “Seed Sample Size” section below the “Procedure” section. This section contained written answers to the following questions: 1) HOW MANY (or what percent) of your total number of harvested seeds will you attempt to germinate in your upcoming experiment? and 2) WHY do you believe the number of seeds you will attempt to germinate is a good number, scientifically speaking?

2) Add a “Seed Selection Protocol” section below the “Seed Sample Size” section. This section contained written answers to the following questions: 1) HOW will you select the seeds you will attempt to germinate in your experiment? and 2) WHY do you believe your seed selection process is a good selection process, scientifically speaking?

Homework: A period students have a seed germination quiz on Thursday. F & G period students have a seed germination quiz on Friday.

Tuesday, March 13th

Today in science: After quickly reviewing the factors that affect seed germination–and reminding students of Thursday’s (A period) or Friday’s (F period) quiz)–Dr. Merritt asked students to open up their Seed Germination Procedure (Google Doc) so that they could continue making some needed improvements. Here is a short list of the things Dr. Merritt asked students to do in class:

1) Add a “Materials” section above the “Procedure” section and use bullet points to list all of the items you will need for your seed germination experiment.
2) Be sure to list the number or quantity of each material needed and, if/when possible, specify the type (e.g., glass vs. plastic) if more than one type is commonly available.
3) Add a sentence or two to your procedure that explains how you will choose the B. rapa seeds you try to germinate in your experiment (we talked a little bit about the why in class).
4) Add a sentence or two to your procedure that tells readers to record the room temperature during every day of the experiment in a lab notebook.
5) Add a sentence to the end of your procedure that uses all of the following terms and phrases: “compare,” “1st generation,” “2nd generation,” and “seed germination,” and “success rate.”

Homework: A period students have a seed germination quiz on Thursday. F & G period students have a seed germination quiz on Friday.

Monday, March 12th

Today in science: After asking students to list the factors that affect seed germination (yet another review of last week’s lessons), Dr. Merritt asked students to open up their Seed Germination Procedure (Google Doc) so that they could potentially make some improvements. Here is a list of the things Dr. Merritt asked students to do:

1) Check for the correct file name of the document. For example, “01F – Seed Germination Method” or “11A – Seed Germination Method.”
2) Be sure the document is shared with Dr. M (brett.merritt@tasis.ch)
3) Underline all of the command verbs found in the procedure.
4) Check to make sure that the first word of every procedure command (sentence) is capitalized and that there is a period (full stop, un punto) at the end of the command.
5) Be sure that every step in the procedure follows Dr. M’s guidelines for writing scientific procedures, which you can see HERE.

Homework: Students are asked to go through the procedures they wrote for their seed germination experiment and highlight the steps and/or phrases in which they discussed the three types of experiment variables. The steps or phrases should be color coded according to the key below:

Manipulated Variable (MV) = YELLOW highlighting
Responding Variable (RV) = PINK highlighting
Controlling Variables (CVs) = GREEN highlighting

Any students having difficulty knowing what their MV, RV, and CVs are for this experiment should look in their Lab Notebook, where all three of them are written.
