Chemistry 9-26-22 Lab Safety & Procedures

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.

Physics 9-23-22 Component Method of Vector Addition

PHYSICS – I missed you today!! 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 9-23-22 Lab Apparatus & Lab Safety Contract

CHEMISTRY: It’s been a great week – you’ve accomplished a lot! Here’s the assignment for today and information on the homework for this weekend.

Lab Apparatus Assignment – 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 on today (Friday) by the end of class. If I counted right, there are 65 questions – 33 pieces of equipment. IMPORTANT: It’s a great idea to do the practice at least once before you do the actual assignment.

Lab Safety ContractSince 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. 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.
  • IMPORTANT: You must have this safety contract submitted to be able to participate in lab for the rest of the year! Due Monday!

Hon Chemistry 9-22-22 Lab Safety Test Overview

HON CHEMISTRY: Great job with evaporating today, and great job in lab this week! Wow – you’ve learned a lot!! God bless you as you finish up studying for tomorrow’s test! Be sure and check out the Lab Safety Stuff to Know sheet on the Test Info tab.

In addition to the lab safety packets and the lab safety video, this is some VERY IMPORTANT information to study

  • All the lab apparatus at your lab station and in the slide show – be able to identify it all and know what all the apparatus is used for.
  • Know the parts of the Bunsen burner and how to light one.
  • Know the parts of the balance and be able to measure mass with a balance AND volume with a graduated cylinder.
  • I’ll ask you about safety control equipment and where it’s found in the lab.
  • I’ll also have the safety symbols and the information they represent on the test
  • Make sure you can both set up or draw and label diagrams for filtering and evaporating

HUGE HINT: Go back and view the earlier posts/slide shows on Lab Apparatus, Lab Tour, Lighting a Bunsen burner, Measuring Mass and Volume, etc. Also, I’ve posted a lab apparatus & uses review on Canvas. All of these are VERY helpful for the test!!

God bless you as you study! It’s a ton of information, but you can do it!! I’ll be praying for you!!

Chemistry 9-22-22 Lab Equipment

CHEMISTRY – There’s a ton of useful equipment for chemistry this year! Below is a slide show with an overview of the apparatus that you’ll use in the chemistry lab. Click on the title above the slide show for a PDF of everything in the slide show. 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 slide show for a PDF of everything in the slide show. 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 for Thursday– Study the lab equipment in the slide show below and then, when you know them, identify the equipment in the Lab Apparatus Review PRACTICE Assignment on Canvas. On the Chemistry Canvas page, scroll down to Assignments and you’ll see the PRACTICE assignment. You are doing the PRACTICE  today before you do the actual lab quiz assignment tomorrow in class. Also, pictures of most of these are in the back of the Safety Packet.

Hon Chemistry 9-19-22 Lighting a Bunsen Burner

CHEMISTRY – Here’s a great refresher on lighting a Bunsen burner! By the way, in lab today, look closely and you may get 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!!

Below is a slideshow with .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 – 6. Be sure and read ahead before you come to class! Also, make double dog sure you are keeping up with the observations in each part and answering ALL of the questions at the end of the lab on pg. 17 – 18. There are a TON of them! Check your syllabus for due dates!

Chemistry 9-19-22 Graphing Exercise 1

CHEMISTRY: Today you will begin Graphing Exercise 1. Don’t forget if you get stuck, you can always go back and check the EXCEL Online Graphs Tutorial handout.

Here are the instructions for Monday – (You are going to be dreaming about graphs!!)

IMPORTANT: A rough draft of your first graph (graph J) is due tomorrow by class time. Check the syllabus for the due date for the entire assignment.

FIRST: You will be doing Exercise 1 with Excel Online. Make sure you are using your Office 365 account with your school email. This way you can do this assignment at school or at home and access it with your own computer, tablet, phone, etc.

FOR TODAY: Click below for the files you need for today. You can also find these handouts under the Worksheet tab.

Hon Chemistry 9-15-22 Lab Safety & Procedures

HON 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.

HOMEWORK: First though, lets talk about homework.(Don’t forget to check your syllabus to see what else is due tomorrow and Monday!!)

Chemistry 9-15-22 Graphing with Excel

CHEMISTRY: Today you are going to learn (or review) how to make graphs using Excel Online.

Here are the instructions for Thursday. (You are going to be dreaming about graphs!!)

IMPORTANT: Your sample Excel graph must include a variable unit (either x or y) that has a superscript or a subscript in the unit. This is so you can practice doing this step. Your sample graph is due Monday by 8:00 A.M. Don’t forget that also Graphing Exercise 2 is due on Monday by 8:00 A.M.

FIRST: You will be making your sample graph with Excel Online. Students can use this for free! Your first step is to sign in to your Office 365 account. Click here to log in https://www.office.com/  (If you haven’t signed up for a free Office 365 account with your school email, STOP and do that first. Instructions are on this weeks syllabus.) Using Excel online, you can do this assignment at school or at home and access it with your own computer, tablet, phone, etc.

FOR TODAY: Today your assignment is to make a sample Excel graph that you will eventually turn in to your Chemistry Shared folder. Click below if you need the files you need for today. You can also find these handouts under the Worksheet tab.
