7th-8th Grade Science: Week of Nov. 16-20

Hello,
A couple of important dates are as follows:
Thursday, Dec. 3 Complete the Chemical Bonds and Reactions Unit with the unit test.
Dec. 4,11,18 Each of these Fridays will be dedicated to the Invent Idaho/Science Fair.
Students working individually or in pairs will develop a plan for an
invention or science fair project and carry it out in preparation for our fair in early February.

I will discuss these dates (along with any homeowork) more in class this week. Have a great week,
-Mr. Pfiester

9th Grade Biology: Week of Nov. 9-13

Hello,
We will finish up our study of Cellular Respiration this week. While many students have excellent classwork grades, many are doing poorly on our chapter tests. With that mind, the Ch. 9 practice test will be on Thursday with the chapter test on Monday, Nov. 16. That will allow students plenty of time to analyze their mistakes and see the concepts/questions that will likely appear on the test. So the homework and DUE dates are as follows:

Wednesday, Nov. 11: 9-2 Section Assessment Questions 1-6 (pg. 232).

Friday, Nov. 13: Complete the multiple choice Ch. 9 Assessment questions 1-10 (on pg. 237) and the multiple choice Standardized Test Prep. questions 1-10 (on pg. 239). You only need to write the letter answers, not the entire question. Example 1) A. 2) C.

Have a great week,
-Mr. Pfiester

7th-8th Grade Science: Week of Nov. 9-13

Hello,
We only have two weeks of school and then Thanksgiving Break! This week, we'll finish our study comparing covalent and ionic bonding and then study chemical reactions. We should finish the Chemical Bonds and Reactions unit by Dec. 4th or so. We will have a Covalent and Ionic Bonding Quiz on Friday. The homework and DUE dates for this week are as follows:


Monday, Nov. 9: Section 2: Ionic Bonds, questions 1-3, all parts due.


Wednesday, Nov. 11: Section 3: Covalent Bonds, all questions, all parts due.


Have a great week,

-Mr. Pfiester

7th-8th Grade Science: Homework over Long Weekend

Hello,
There is an assigned homework over the long weekend coming up. I will be distributing Section 2: Ionic Bonds today. Your homework and the DUE date are as follows:

Monday, Nov. 9: Read Section 2 and complete the assessment questions (p. 163) 1-3, all parts.

Have a good weekend,

-Mr. Pfiester

9th Grade Biology: Week of Nov. 2-6

Hello,
We have now started the 2nd Quarter. Due to parent-teacher conferences, Thursday will be a half-day with school letting out at the end of 4th period and there will be no school on Friday. We will be making yogurt on Tuesday so please bring in the following to school on that day: medium sized sauce pan, a whisk, 1 cup, 1/2 cup, and Tablespoon measuring spoons. The only homework and the due date are as follows:

Wednesday, Nov. 4: Read over the "Problem Solving" section on pg. 224. Using complete sentences, label the homework and complete the following: Defining the Problem, Organizing Information, and Creating a Solution.

Have a great week,
-Mr. Pfiester

7th-8th Grade Science: Week of Nov. 2-6

Hello,
We have now started the 2nd Quarter. Due to parent-teacher conferences, Thursday will be a half-day with school letting out at the end of 4th period and there will be no school on Friday. Last Friday, we conducted an experiment to determine whether the following would conduct electricity: tap water, salt, saltwater, sugar, and sugar water. The only one to conduct was saltwater (an ionic solution). Your only homework for the week and the due date are as follows:

Wednesday, Nov. 4: Your assignment is to pick a nontoxic liquid from home (such as orange juice, milk, pickle juice) to test whether it is a conductor of electricity. Monday I will give you a film cannister so that you can transport the liquid from home. Bring in the liquid from home on Wednesday and answer the following questions:

1. Is your liquid composed mostly of ionic or covalent bonds?
2. Remember, ionic solutions usually conduct electricity, while covalent solutions do not. Based on this information, do you predict that your liquid will conduct electricity?

Wednesday afternoon each student will have the opportunity to test their liquid for conductivity.

Have a great week,

-Mr. Pfiester

9th Grade Biology: Week of Oct. 26-30

Hello,
The year is passing so quickly. The last day of the 1st Quarter is this Friday. Parent-teacher conferences are scheduled for next Thursday and Friday (Nov. 5-6). For the next day or two, students will conduct short presentations on their cell model. We will then begin Chapter 9: Cellular Respiration. We will make bread and yogurt as they are products of cellular respiration. Due to the presentations and difficult material related to cellular respiration, the only homework for the week is as follows:

DUE Friday, Oct. 30: Section 9-1 Assessment Questions (p. 225) 1-6, using complete sentences.

Have a great week,
-Mr. Pfiester
