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.
Here’s the review that we went over in class. 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. 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: So now that you know how to use all the tools we’ll need in chemistry, it’s time to start talking about ….chemistry!!
Were you able to able to make applications with the branches of chemistry and categories of scientific work? We’ll finish talking about the properties of matter tomorrow. Don’t forget the applications!
PHYSICS – How’d you do with relative motion “revisited”? You know, you’ve done this already. The only new part is the motion of objects in the same direction and opposite directions, relative to each other. Don’t forget, you’ll use what you learned about vector addition to work those “boat goes across a river” and “plane experiences a head wind” types of problems. You’ve got this!
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 – Today you’ll be using what you know about the scientific method to analyze a myth that was tested on Mythbusters. Be sure and follow the Mythbusters Questions worksheet. If you need a copy of the Mythbusters questions, you can find them under the Worksheet tab.
If you are absent from class and are doing this assignment at home, you may watch any Mythbusters episode on the Discovery Channel or an episode online. Check the syllabus for the due date!
CHEMISTRY – Great job lighting Bunsen burners today! By the way, did you happen 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!!
Here’s something you will find useful in the future…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.
Next week we’ll continue with Parts 4 & 5. Be sure and read ahead before you come to class! Also, make double dog sure you are keeping up with the observations and answering ALL of the questions at the end of the lab on pg. 2- 17. There are a TON of them!!!
CHEMISTRY: Here is info on how to write your lab safety contract and also below is the lab safety video we will watch in class on Wednesday. The video 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 also check your syllabus!!)
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. You must have this safety contract submitted in your shared folder in order to do the Bunsen burner lab on Thursday:
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.You must have this safety contract submitted to do lab for the rest of the year! Due Thursday!
PHYSICS – Hey guys, great job today on the intro to vectors – graphical vector addition, resultants, and the like. Have you done anything like this before? Great start today! Don’t forget your protractor and graph paper!
