4. 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.

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).

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

2) In your textbook:- Pg. 26, # 5- Pg. 44 # 5, 6- Read Pg. 45-49. Write down 6 of the physical

properties discussed.
