PHYSICS – Hey guys, great job today drawing motion with vectors – graphical vector addition, resultants, and the like. Have you done anything like this before?
A couple of super important things – GRAPH PAPER(!) and sketch it out before you start so you’ll know where to place the first vector with out running off the page. Also, graphical addition is adding vectors head to tail – then the resultant is found from the tail of the first vector to the head of the last vector. Get the direction by measuring from the tail of the resultant.
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.
Tomorrow 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. 13 – 18. There are a TON of them!!!
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 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), 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: “I 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!
