Hon Chemistry 9-24-20 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 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), write the lab safety statements as your contract.
  • They may be handwritten on notebook paper or typed.. 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. Even if you type the safety rules, you’ll need to hand write this last part and then scan an IMAGE of your hand written statement and signature/date at the bottom.
  • Scan your final document as a PDF and submit it into your Chemistry Shared Folder. You must have this safety contract submitted to do lab for the rest of the year! Due Monday!

Hon Chemistry 9-23-20 Lab Equipment

HON CHEMISTRY – Hey guys! 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 black arrow to start the slideshow. For all of the equipment:

  • 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. I think you’ll find it 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 on Power School. Once you start, you will have 30 minutes to complete the assignment. It’s due on Monday by 8:00 A.M.. If I counted right, there are 33 of them.

By the way, there is also a Practice Review on PowerSchool Learning 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 9-21-20 Graphing Exercise 1

HON CHEMISTRY: Today you are going to learn (or review) how to make graphs using data analysis software like Google Sheets or Excel by watching the video below at your own pace.

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

IMPORTANT: A rough draft of your first graph is due tomorrow by class time. The entire assignment must be submitted by this coming Friday, September 25, 8:00 A.M.

You can do this assignment at school or at home with your own computer. If you use any device other than a PC or any graphing tool other than Excel or Google Sheets, you may need to modify the instructions to fit your device.

  1. Watch one of the vodcasts below for a tutorial on how to make graphs in Excel or Google Sheets.
      • My advice is to use a split screen view on the laptop with the video on one side and Excel open on the other side of your laptop screen. Watch the video and at the same time pause it as you follow along with the steps in Excel. Holler if you need me to show you how to do a split screen view. Or Google it! πŸ™‚

     

  2. When you begin working on the Graphing Exercise 1 assignment, pay very close attention to the instructions. Also, pay close attention to the sheet on How to Make a Best Fit (Scatter Plot) Line Graph in Excel 2010 – UPDATED to make sure you have all the parts of the graph covered.
  3.  

  4. Google Sheets only: If you ever need to add subscript or superscripts to the axis labels in Google sheets, try copying and pasting whatever number you need from this set in to the axis title in Google sheets: β°ΒΉΒ²Β³β΄β΅βΆβ·βΈβΉβ‚€β‚β‚‚β‚ƒβ‚„β‚…β‚†β‚‡β‚ˆβ‚‰

Now go forth and conquer graphs!!

Hon Chemistry 9-16-20 ID of Unknown Lab

HONORS CHEMISTRY – Happy use your brain day!! Can you now use what you’ve learned about density? Who is going to be your spokesperson? When is your lab going to be due? Do you need two due dates???

One change – instead of posting your discussion here on the class website. Post your discussion on the Discussion Board on PSL.

Can’t wait to “watch” you work!

Hon Chemistry 9-9-20 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 look again at density, and then our overview of direct and inverse proportions. Just brief info for the test for now, and we’ll put it to practice in a couple of activities after the test.

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 9-4-20 Problem Solving – #79

HON CHEMISTRY: Great job using conversion factors and densityto work more advanced problems! 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 show the validity of your work – by using correct formulas and/or converting from one unit to another using the Q-formula. (And yes, you have to do it that way!). Now go forth and conquer!

Hon Chemistry 9-3-20 Using Density

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 8-31-20 Scientific Notation & Conversion Factors

HON CHEMISTRY: Can estimate out how fast you can drive in at least one parking lot in Guatemala – and can you show me how you solved the problem? Even better, can I trust the validity of your work?

Good job on remembering how to use conversion factors! 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!)

There’s problem with today’s vodcast – NO AUDIO! I’m posting it below if you’d just like to follow the writing. Below that I’m posting the vodcast from last year – it has audio but we didn’t get as far in the lesson last year as we did today in class.But that may be good for you!
