HON CHEMISTRY: Great chapel today, but that means super, super short class. Here’s our very, very brief review of physical properties and states of matter. By the way – what state of matter is snail slime? Hmmm…
CHEMISTRY – Great job lighting Bunsen burners today! By the way, did you happen to see a green flame when you put the copper wire in the flame? The electrons in the copper atoms were being excited and they gave off a green flame. Cool!!
Here’s something you will find useful in the future…everything you wanted to know about a Bunsen burner and how to light it. Be sure and view the slide show BEFORE you take turn in your lab sheets and take the test.
Tomorrow we’ll continue with Parts 4 & 5. Will you be ready: (Hint, hint!!) Be sure and read ahead before you come to class! Also, make double dog sure you are keeping up with the observations and answering ALL of the questions at the end of the lab on pg. 12- 17. There are a TON of them!!!
HON CHEMISTRY: No audio today, so I’m posting an old lesson. So now that you know how to use all the tools we’ll need in chemistry, it’s time to start talking about ….chemistry!!
Were you able to able to make applications with the branches of chemistry and categories of scientific work? We’ll finish talking about the properties of matter tomorrow. Don’t forget the applications!
Now it gets interesting! 🙂
PHYSICS – No audio today, so I’m posting a lesson from last year. Great discussion of relative motion! You know, we’ve done most of this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other.
Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems.
In case I forget tomorrow and you want them, here are the answers to Thursday night’s problems.
41. a. 70 m/s east
b. 20 m/s
43. a. 10.1 m/s at 8.53° east of north
b. 48.8 m
44. a. 14.1° north of west
b. 199 km/h
45. 7.5 min
46. a. 23.2° upstream from straight across
b. 8.72 m/s across the river
50. a. 22.2 s
b. 2.00 × 102 s
52. 22.5 s
54. 70. s
PHYSICS: I do believe you are well on your way to conquering the component method of vector addition. Good job! Pay careful attention to the smallest details – it can make a huge difference.
Here’s the overview of the conceptual questions from the homework – super short!
CHEMISTRY: Wow! Great video, but do you feel like you have information overload!?
Here is the lab safety video we watched in class. It does have a ton of info, and the thing is, you absolutely must know it – and not just for the test, but also throughout the year in lab. It’s a really good idea to watch it again and take notes as you go.
Lab Safety Contract –Since we’ll be in lab so much, it’s important that you write your own lab safety contract. Here’s how you do it::
- From the first couple of pages of the Safety Packet that you got in class (or it’s also here under the Lab tab), hand write the lab safety statements as your contract.
- They must be handwritten on notebook paper. For the heading: Lab Safety Contract
- You only have to write the first part of the rule that is bold. There are 29 in all and they almost all start with “I will…”.
- At the end of your contract – after the last statement, hand write the following statement at the bottom: “I agree to abide by these rules.” Then sign underneath and date it.
- Scan your final signed document as a PDF and submit it into your Chemistry Shared Folder. The assignment name is Lab Safety Contract. Make sure it is a clean, clear scan!
- IMPORTANT: You must have this safety contract submitted to be able to participate in lab for the rest of the year! Due tonight, Tuesday, by 11:59 PM!
PHYSICS – Are you on your way to conquering the component method of vector addition? So which do you like better? Give yourself a chance to get used to separating everything into x and y and it will click, I promise!
CHEMISTRY – There’s a ton of useful equipment for chemistry this year! Below is a video with an overview of the apparatus that you’ll use in the chemistry lab. Click on the title above the video for a PDF of everything in the video. For all of the equipment, here’s what you need to know:
- Know the name of each item.
- Explain the use of each item (it’s written in white on the slide)
The second slide show is a great tour of our lab. It’s very important information about where stuff is and what it’s used for. Click on the title above the video for a PDF of everything in the video. I think you’ll find the lab tour very helpful. Both of these would be a great way to study equipment for the test! (Hint, hint!) 🙂
Lab Apparatus Assignment #1 – Study the lab equipment in the slide show below and then, when you know them, identify the equipment in the Lab Apparatus Review Assignment on Canvas. On the Chemistry Canvas page, scroll down to Assignments and you’ll see the assignment. Once you start the assignment, you will have 20 minutes to complete it. It will count as a lab grade. It’s due TONIGHT, Monday, by 11:59 PM.. If I counted right, there are 33 questions – 33 pieces of equipment. IMPORTANT: It’s a great idea to do the practice at least once before you do the actual assignment.
IMPORTANT: It’s a great idea to do the practice at least once before you do the actual assignment – especially as you get ready for the test next week. . The Practice on Canvas will let you practice before you do the actual assignment. Also, pictures of most of these are in the back of the Safety Packet.
Lab Apparatus Assignment #2 – This one is due NEXT Sunday night, 10/1, by 11:59 PM, and is a big one. It has BOTH the equipment to identify AND the uses of them. Study the lab equipment in the slide show below and then, when you know them, identify the equipment in the Lab Apparatus Review Assignment on Canvas. On the Chemistry Canvas page, scroll down to Assignments and you’ll see the assignment. Once you start the assignment, you will have 20 minutes to complete it. It will count as a lab grade. If I counted right, there are 65 questions on this one. IMPORTANT: It’s a great idea to do the practice at least once before you do the actual assignment.
CHEMISTRY: Today we spent the period looking at your graphs, but first we did one last look at some things to watch out for on your graphs and on the questions.
IMPORTANT: Check the project sheets for the exact order of how you turn in everything!! After you assemble everything in a doc, then make sure your name heading and the title are correct on the first page (do this like you would a lab report). Finally, you’ll save it as a PDF and turn it in two both your Google Drive Shared folder and turnitin.com.
Check the syllabus for the due date!
PHYSICS – Hey guys, great job today on the intro to vectors – graphical vector addition, resultants, and the like. Have you done anything like this before? Great start today! Don’t forget your protractor and graph paper!
