Thursday and Friday in class…
- Mrs. Roll, our new 8th grade counselor, presented information about high school registration. Registration week starts next Monday!
- We finished taking notes (on your own) over the last two sections of chapter 21.
- If you did not finish the section review questions in class for sections 3 and 4, you need to finish them for homework.
Remember that if you did not like the grade you made on the Waves test and want to do a re-take you MUST come to 2 help sessions before I will schedule a re-take with you. You only have until Tuesday, Feb. 16th to complete BOTH help sessions. If you do not make the effort to complete your help sessions before that date you WILL NOT be allowed a re-take for this test. Help sessions will be offered on both Tuesday and Thursday at 8:15 AM up until that date!
Tuesday and Wednesday in class we will be starting the chapter on sound. Tests from chapter 20 will be handed back. Please keep up with all notes, questions, quizzes, tests, etc. You will need all of these to help you study for the cumulative post-test at the end of the Waves, Light, and Sound unit.
Classwork for Tuesday and Wednesday: Notes on sections 21-1 and 21-2. Section review questions for those two sections. If you did not finish the questions in class you need to finish them for homework!
Ok…we’ve taken the quiz. We’ve completed the labs. You’ve had time to review in class. It’s time for the test!!!
A-day students will be taking the test on Friday and B-day students will be taking the test on Monday. Make sure to study. This chapter is mostly vocabulary!! Chapter 20 Study Guide
Chapter 20 Study Guide
Vocabulary:
- Amplitude
- Frequency
- Wavelength
- Wave speed
- Electromagnetic wave
- Longitudinal wave
- Mechanical wave
- Medium
- Surface wave
- Transverse wave
- Wave
- Diffraction
- Interference
- Reflection
- Refraction

Study and be able to explain Figure 1 on pg. 574.
Study and be able to explain Figure 4 on pg. 576. Also look over your rev. question on Super Nova explosions.
Be able to draw a longitudinal and transverse wave. Label the following: amplitude, compression, crest, rarefaction, trough, and wavelength.
What are the properties of waves?
What happens to wavelength when frequency is cut in half?
How do waves transfer energy?
We have spend the last few classes looking at the basics of waves. There will be a quiz next class over chapter 20. MAKE SURE YOU KNOW YOUR VOCABULARY!!!
Today in class we finished up notes on section 3 (wave interactions) and did the last set of section review questions. We also completed 3 wave mini-labs. Any of this information along with any information from last class is fair game for the quiz!!
Tuesday and Wednesday in class we took notes on sections 1 and 2 of chapter 20 (Waves and Wave Properties). The section reviews for these two sections (and the vocabulary and notes) will be checked at the beginning of next class.
Parents – we are still in sneezy, runny nose season. I am happily accepting donations of tissues and hand sanitizer! Anything you can send in would be greatly appreciated!!
Today in class students worked on corrections for their Chemistry Quiz. Grades were a little low and we needed to spend a bit more time looking at this information before moving on. The last half of class we started our introduction to waves. Next week we will finish up notes and start working on some labs about waves.
5B and 7B are a little behind the other classes. They will be completing their Chemistry Quiz in class on Friday. We will still do the introduction to waves, but will save corrections for sometime next week as we scramble to catch up!
I will have grades from the first two week in Pinnacle by Sunday evening. If you have not taken the Chemistry Quiz, please make that up as soon as possible. Remember that you only have the same number of days to make up work as you missed. For example, if you were out 1 day you only get one extra class to make up the work. If you were out 2 days you get 2 extra days to make up the work. It is your responsibility to make sure you get your missing assignments.

What are the only parts of an atom that make chemical bonds?
What is the same within each group on the periodic table?
Why don’t noble gases normally form chemical bonds?
What is the charge of a sodium ion with 11 protons and 10 electrons?
What happened to bonds during a chemical change?
What are the signs of a chemical reaction?
What is the force that holds atoms together called?
What causes chemical bonds in molecules to break?
How do substances form during a chemical reaction?
Make sure you can balance equations like the ones we practiced in class.
What does the law of conservation of mass state?
Which compound has the weakest chemical bond?

Know the properties of acids and bases.
Know the following vocabulary: Ions, ionic bond, covalent bond, valence electron, covalent compound, chemical bond, indicator, base, acid
If you have been informed that you WILL NOT be participating in the pancake lab, here is your study guide. The test is 64 multiple choice questions. Chemistry of Cooking Test Study Guide
Today we took the short quiz over the periodic table and then reviewed the information for the first half of the chemistry of cooking unit. The assessment for this half will be on Wednesday for B-day and on Thursday for A-day.
Unfortunately, behavior has been less than wonderful. I know that as we get closer to the end of week it is more and more difficult to focus. Students were warned that if their classroom behavior was not good they would not be participating in the pancake lab. Sadly, there are already students who will have to do the alternate assessment. I am currently working on a study guide for those students and will have it posted by mid-day tomorrow.
Students in my 5B class, since half of the class was trying to be cooperative while the others were off task only those who were off task will be completing the alternate assessment. If you’re not sure which category you fit in, come see me and I’ll let you know.
We took notes on the Periodic Table today in class. Students who did not complete the heat transfer diagrams last class finished that today(see the previous blog entry if you are still working on it). Everyone was also given the Periodic Table scavenger hunt. Any work not completed in class needs to be finished as homework.
Next class there will be a quiz over the Periodic Table. Studetns need to use their color-coded table to study from!
