- Any Q’s from ch7 worksheet? Due Friday, April 3 along with ch7 notes.
- Quiz on ch7 on Friday, April 3.
- I will be able to draw Lewis Dot structures.
- Do: Worksheet Electron Dot Structures Worksheet
- Do: read ch8. Sec1-3 intro; (sec.4 is part of the ch7 test as it talks about periodic trends in electronegativity); sec.5 – how to draw Lewis dot structures in more detail. We will look at some of the exceptions to the Lewis dot structures when we return from Spring Break and that’s it for chapter 8!
- See here for an advanced copy of the ch.8 review worksheet and answer key: ch8 worksheet and Chapter 8 Review Worksheet Answer Key.
- Activity: Cow’s eye dissection. See copy of handout here: Cow Eye dissection from the Exploratorium. Complete the questions. Draw a picture of the interior and exterior of the eye and label the parts you can see.
- Progress report and Work habits self-evaluation and goal setting sent home. If you are missing assignments, tests, or have an “I” standing and need to complete it, work on it during Spring Break and see me when we return back to school.
- Today, students wrote the Qu-est on sections 4.7-4.11 (strengths of acids and pH calculations) and Lab20B.
- Today, students wrote the chapter 1 test (Cells and the Microscope).
- Check last day’s blog for the list of assignments you should have completed and handed in for chapter 1. If you still need to complete them, try to finish them by the end of this week.
- Do: read over the Cow’s Eye Dissection handout. See copy here: Cow Eye dissection from the Exploratorium. We will be doing the lab next class. You can answer some of the questions before you do the lab! See this website for a “virtual” lab, video, and extra info: https://www.exploratorium.edu/learning_studio/cow_eye/
You can bring your own gloves if you’d like.
If you cannot be in the room when we do the lab, please talk to me before your lab day so I can prepare and alternative assignment for you. It will be from your textbook: p.235 Natural Vision Systems – you will be doing “Report Out” #1a where you will make a Venn diagram comparing the vision systems of a creature of your choosing to that of a human. For ideas of what kinds of creatures to choose, see here: http://thescienceexplorer.com/nature/12-coolest-eyes-animal-kingdom
- Fizz Quiz: periodic trends.
- Periodic Trends worksheet: what are some exceptions you were supposed to notice? Why do they happen?
- Video: Floo powder – chemistry in action!
4. Activity: Flame tests –make note of which color each element turns into.
5. Do: chapter 7 review worksheet. See copy here: ch7 worksheet. Finish your chapter 7 notes, focusing on the periodic table and the trends (and the principles of attraction and repulsion!!) See answer key here: Chapter 7 Review Worksheet – Periodic Trends -Answer Key
- Hand back pH worksheet. Any Q’s?
- Go over Lab 20B analysis and do a practice lab quiz.
- I will be able to calculate the pH after an acid-base neutralization reaction, even when they don’t fully neutralize the solution.
- Do: Read section 4.12 and do #60 and 62 on p.143.
- Quest focused on sections 4.7- 4.11 next class. There will be about 15 multiple choice questions and the written section will be a quiz based on analyzing strenthgs of acids like in Lab 20B.
- Go over section 1.3 worksheets.
- Quizlet: a resource to help you practice/study (especially good for vocabulary) https://quizlet.com/102927827/bc-science-8-chapter-1-flash-cards/
- Make your study card. Only one side of the card is allowed!
- Reminder: Next class: ch1 test. There will be about 30 multiple choice questions (bring a pencil) and a written section. Major topics: characteristics of living thing; how to use a microscope; cell parts and functions; diffusion and osmosis
- Reminder: Cow’s Eye Dissection next week. See handout here: Cow Eye dissection from the Exploratorium

- Warm up!
- Go over worksheets on Coulombic Attraction and Periodic Trends.
- I will be able to explain how coulombic attraction between protons and electrons and repulsion between electons can be used to predict the size of atoms, the ionization energy, the electronegativity, and electron affinity.
- Read sections 7.2 to 7.5. Do: #17, 35, 43
