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!!

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!

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!!)

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 15 minutes to complete it. It’s due on Friday by 10:00 A.M.. If I counted right, there are 33 of them. IMPORTANT: There’s a practice that you can use 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: β€œI 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 9-15-22 Lab Equipment

HON 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!) πŸ™‚

Lab Apparatus Assignment – 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 15 minutes to complete it. It’s due on Friday by 10:00 A.M.. If I counted right, there are 33 of them.

By the way, there is also a Practice assignment on Canvas that you can practice with before you do the actual assignment. Also, pictures of most of these are in the back of the Safety Packet.

Hon Chemistry 8-31-22 Chapter 2 Overview

HON CHEMISTRY – God bless you as you prepare for your first test! Here’s the short overview of the test that we did in class today. At the end is a look at some of the questions/answers from the sample test and review.

Need some extra practice? Help session Thursday morning, 7:30 A.M. It’s come and go.

As you study, don’t just read your notes and memorize! You must practice your notes, practice the problems, practice the memorization!!

Also, don’t forget the Interactive Review Games with your online text and also sciencegeek.net. God bless you as you study! I’ll be praying for you!!

Hon Chemistry 8-30-22 Finding Relationships Between Data

HON CHEMISTRY – You’ve learned to gather the “pieces of the puzzle”, now it’s time to put them together so they can have meaning! Here’s our overview of direct and inverse proportions and a quickish review of graphs. Just brief info for the test for now, and we’ll put it to practice in a couple of activities after the test.

Speaking of putting things together, how’d you do with the density homework. We hit some of the bigger problems today after our discussion of graphs.

So we finished the chapter today! Ready for the test? As you study, remember, don’t just read your notes – practice your notes, practice the problems, practice the memorization!! By the way have you had a chance to check out the Chapter 2 Stuff to Know sheet and the chapter 2 study suggestions sheet? They are under the Test Info tab.

Hon Chemistry 8-29-22 Using Density & HW Review

HON CHEMISTRY – Here’s a pic of some “high density” koi that I saw in Hawaii (at the Dole Pineapple Plantation, of all places!). Great applicaitons of density today! 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?

Hon Chemistry 8-26-22 Conversion Factors, Pt. 2

HON CHEMISTRY: Great job using conversion factors to work more advanced conversions! It’s good to able to convert from one unit to another, but can you use that info to solve a real world problem?

Remember, this isn’t just about getting an answer – some of you can do that in your head. This is about being able to convert from one unit to another using the Q-formula. (And yes, you have to do it that way!). Now go forth and conquer!
