Hon Chemistry 9-21-11 Classification of Matter

HON CHEMISTRY: Man – you’ve gotta love homecoming week! I don’t think I’ve talked so fast in a long time, and we still didn’t finish. So………we’ll finish tomorrow, but I decided to go ahead and post the full lecture from last year on the classification of matter so you’ll have it all in one place. How are you doing on the examples of homogeneous and heterogeneous matter? Here’s a question to think about, can you tell me three different types of homogeneous matter?

Lab tomorrow! After we finish the notes on pure substances, you’ll start designing another lab. Heads up – you might want to review the types of properties (qualitative & quantitative, etc.) and physical and chemical changes. I’m just saying. πŸ˜‰

  1. Ms. Skinner,
    I came by at the end of school to ask you a question about tonight’s homework but found that you had left early for a dentists appointment. I was wondering if the homework listed on the syllabus for tonight was due tomorrow. Someone had said that you said something about it after student council left. Thank you!

    • Candice – Thanks for coming by, and sorry I missed you! Homework for tonight is to go back over # 22 – 23: 16 – 21, 25, 27, 28, 33. Element Handbook search 1 and 2 will be due Monday. We’ll finish notes on the elements tomorrow. πŸ™‚

    • Nicole – When you boil water, it just changes states – from a liquid to a gas. So that means it’s just a physical change. Your test will be next Tuesday – right before Fall Break.

  2. Will we need to be able to know more of the elements (along atomic numbers, mass numbers, etc.) for the test or just the first thirty?
