Thursday 10/7/2010Do Now

What is the objective of today’s class?

What are the 2 main categories of mixtures?

What is an example of a heterogenous mixture?

When is your super easy pop quiz?


Class Checklist

  • No students were talking during the review of the Do Now, during teaching time (note-taking) and during closing. (2x)

  • Every student was on time

  • No curse words were used inside this room.

  • Every student remained in his/her seat until independent practice.

  • By the time Ms. Chan goes over this list, every table has 2 chairs behind it.

  • All students followed the class rules. (Students did not argue with Ms. Chan; everyone tried their best)

  • Every student brought THEIR OWN pencil and paper to class.

  • Every student followed directions the first time they were given.

  • Every student completed ALL the class work (including: Do Now, notes, class work)

  • No student had his/her head down during class.

  • It took Ms. Chan no more than 10 total seconds to get the entire class’s full attention (eyes forward, mouths shut).


Review Do Now

  • What is the objective of today’s class?

  • What are the 2 main categories of mixtures?

    A:HOMOGENOUS

    HETEROGENOUS

  • What is an example of a heterogenous mixture?

    A:Italian salad dressing.

  • When is your super easy pop quiz?

    A:Today, after taking notes.


Announcements

  • 2nd PERIOD:

    • Your test corrections need to be in the Assignment Box by the end of this period or I will not give you the extra points.


Announcements

  • When I give you back graded work, don’t give it back to me unless I write on your paper: “Finish for more points!”

  • Keep your work in a folder. If you need one, come back after school and I will give you one.


Announcements

  • Pop quiz is TODAY after you take notes. It will be an open note quiz.

  • Progress reports will be distributed tomorrow.

  • Your first notebook check will be next FRIDAY. More details on Tuesday next week.


Agenda

  • Review mixtures and solutions orally

  • Notes on solutions (1 slide)

  • Review Video.

  • Physical Properties (2 slides)

  • Pop Quiz!

  • Homework: On the whiteboards.


REVIEW (don’t copy this down)

  • Matter

    • Anything that has MASS and takes up space (VOLUME)

  • Mixture

    • combination of 2 things not chemically bound together

  • Solution

    • a homogenous mixture of 2 substances evenly distributed

      • Solute (ex: sugar)

      • Solvent (ex: water)


  • Notes begin on the next slide.

  • Remember: you are responsible only for what is BOLDED and UNDERLINED.


10/7 Notes

*Solutions

  • Saturated solution – the max amount of solute has been dissolved

  • Supersaturated solution – more than the max amnt has been dissolved. Precipitate is formed at the bottom of the cup.


Review Video


*Physical Properties

  • Characteristics of matter that can be observed using your senses; the substance is NOT changed into something different.

  • Used to separated mixtures.

  • Include:

    • Color

    • Viscosity (resistance of a liquid to flowing)

    • Luster (shininess)

    • Ductility (ability to bend/stretch w/o cracking)

    • Density

    • What is a physical property of your lab desk?


*DENSITY

  • How much matter is in a certain volume of a substance

  • Equation:D = m/v

    Density = mass/volume

  • SI Units:g/cm3

  • NOTE:1 cm3 = 1 mL

  • Liquid water has a density of 1 g/cm3.

    • If something is MORE dense (ex: brick), it sinks.

    • If something is LESS dense (ex: ice), it floats.


Both the sponge and the brick have the same volume. Which is MORE DENSE?


POP QUIZ!!!(15 points)

  • You may use your OWN notes.

  • 15 questions – each worth 1 point.

  • When you are done, raise your hand and I will collect the quiz from you.

  • Next, copy down the homework for tonight (in red, on both sides of the whiteboard).

  • Good luck!


Homework – each worth 5 pts. Both are due tomorrow (Friday).

  • ACHIEVE 3000 (the website is: www.empower3000.com. This week’s article is about wildfires).

  • In your textbook:

    • Pg. 26, # 5

    • Pg. 44 # 5, 6

    • Read Pg. 45-49. Write down 6 of the physical properties discussed.
