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.

Science 9
Midterms are in two weeks. Science 9 is on Monday, November 2nd first block of the day. The mid-term is written in the classroom. The entire space unit is on the exam and a portion of Matter. Today in class, we discussed pages 16 - 18 in the text, Properties of Matter. The set of notes from the last two days are on my Wikisite. To access them, go back to the GMCS website and hit the main page of my blog. On the left column, there is a link to my Wiki.

Chapter 8 – SAMPLING
Page 331 in text book
People collect data because they need information. Instead of surveying the entire population, a small portion, called a sample, is studied.
A representative sample truly represents a population. It MUST:
• Reflect the population. This means all parts of the population are fairly represented.
• Ensure all members of the population have an equal chance of being selected. That is, the sample members must be chosen at random.
When we use sampling to survey a population, the sample must be random and must accurately reflect the population.
A biased sample has characteristics not typical of the population.

HOMEWORK for Friday, October 16: page 334/335 questions 1, 2, 4

Math midterm: November 5th

Science 9
We have started our new unit in Science - Matter. Yesterday and today we discussed the Big Bang Theory. Tomorrow, we will be looking at the Properties of Matter beginning in the test book on page 16.

Math 9
There is no homework tonight. However, there were 12 students who did not complete homework last night so get it done for tomorrow! We will continue scatter plots and line of best fit tomorrow.
