Science 9 Matter Review for Midterm

MATTER, Unit 1. Review the definitions in your text of all vocabulary words. My BLOG has all the pages you should review and my WIKI has all the notes we have taken.

1.
a. Malleability f. ductility
b. Hardness g. State
c. Density h. Precipitate
d. Viscosity i. Solubility
e. Corrosion j. Luster

( b) 1. an objects resistance to being scratched.
( f ) 2. When an object can be drawn into a thin wire.
(d) 3. Refers to how easily a liquid flows.
( i ) 4. Is the ability of a substance to dissolve.
( h ) 5. Cloudiness formed when two substances are mixed together.
( c ) 6. Is the amount of a mass per unit volume of matter.
( j ) 7. Whether an object shines.
( e ) 8. slow chemical change when a metal reacts with oxygen
( a ) 9. When a substance can be hammered or bent into different shapes.
( g ) 10. Whether an object is a solid, liquid or gas.

2. The following are examples of chemical or physical change (see page 28 and 29)
Changing an objects shape  (Physical)
Complete change in colour  (Chemical or Physical)
Hard to reverse  (Chemical)
Change in state  (Physical)
Heat or light is given off  (Chemical)

Three chemical properties of matter: combustibility, reaction with an acid, flammability(see page 18 and 19)

The physical properties of matter noted on (page 16 and 17)

Three components are necessary for combustion: fuel, heat, oxygen (see page 38 and 39)

3. Give one example of corrosion: rust (see page 34 and 35)

Science 9 - notes
Physical Changes (from mini-movie)
A physical change is a change in shape, state and size without adding any new substance.
For example: water changes state from solid, liquid and gas. Peanuts, when ground change to peanut butter, there is a change in state, size and shape; but there is no other change.
MIXTURE
A mixture is when two or more parts are blended together and keep their own properties.
Example: salad, bridge mixtures or tacos. Other examples include: tea (which can be strong or weak), sugar and water, or air mixture of different gases.
In a mixture, you can have a physical separation by taking the pieces apart; ie. Use a magnet to separate the magnetic pieces from a powder.

SOLUTION
A solution is a difficult to separate MIXTURE; substances are completely blended and properties are not changed. Substances stay blended such as: tea, fruit juice, soft drinks, water and sugar, salt and water.
Solubility: the measure of the amount of dissolving one substance in another.

A mixture of metals is a solid solution
Air is a solution of several gases.


MATH 9
We are working on adding, subtracting, multiplying and dividing fractions. Also this week, we studied relative frequency and scatter plots. All these topics will be on the midterm. See my wikiblog for Math 9 powerpoint on fractions.

Science 9
Midterms are fast approaching and we have moved onto a new unit, a portion of which students are responsible to know. In addition to the space unit, students will have completed chapter 1 in the text. These pages include only: 14, 16 - 19, 28 - 29, 30, 34, 38 - 39.

BLOG FOR FRIDAY, OCTOBER 2ND GIVES A FULL LIST OF REVIEW PAGES AND CONTENT FOR MID-TERM.

Yesterday and today we completed an in class lab on Physical Properties of Matter and discussed the difference between qualitative and quantitative properties. Our lab included properties of matter we describe with our senses.

Midterm Schedule

October 19

Science 9
In class today we discussed Safety Symbols and WHMIS. Students drew the symbols in their notebook and answered questions A - J on page 15. This is homework if not completed in class.

At home tonight, students are to look around their house and find the following:
a) find products with safety symbols on them and note what the symbol is and what the product is
b) Note where the product is stored.

Students should bring their findings (written on looseleaf) to class Tuesday.

English 123
We wrote down vocabulary words on Chapters 1 and 2.

Thank you to Jeremy - who had the Fashion-Work of the day for his excellent example on how to answer questions in full. He answered the questions in full sentences, used proper grammer and answered each question in full. Good job.
