Hon Chemistry 9-15-22 Lab Safety & Procedures

Posted on by

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 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. 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 9-15-22 Graphing with Excel

Posted on by

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.

EXCEL Online Graphs Tutorial

Checklist for a Good Graph

SAMPLE EXCEL GRAPH: Copy my data from the Excel Tutorial to use for your graph. Make the y axis Mass (g) and the x axis Volume (cm³). Follow the tutorial for instructions on how to make your sample graph. Read below for how to include superscripts and subscripts.

Excel Online Subscripts & Superscripts: If you ever need to add subscript or superscripts to the axis labels in Excel online, you can copy and paste whatever number you need from this set in to the axis title.
