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!

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.

Chemistry 9-1-22 Using Density

CHEMISTRY: Great review on density concepts and problems today, and more! Remember, in chemistry we use math as a tool, therefore we might work problems a little differently in chemistry than you do in your math class.

When working these problems, don’t forget to follow the problem solving steps we discussed today:

  • Analyze – write down what you’re given and what you’re looking for
  • Plan – write a formula where you isolate the unknown on one side by itself
  • Compute – plug in your data, numbers and units; then cancel the units, and if they cancel correctly, go on to the calculator. Be sure and give your answer what the correct units.
  • Evaluate – does your answer make sense, have you used the correct units, do you have the correct sig figs?

Chemistry 8-31-22 Conversion Factor Problems, #50, 68, 91

CHEMISTRY: How are you doing with these longer conversion factor problems? Remember, you’re not just trying to get an answer. Most importantly, you are learning to express a logical progression of thought – from one unit to another. Keep practicing until you can do it by yourself with no help!! Here’s our work on #50.68 and 91.
