Ch. 6 Matter Can Be Classified - Test Review Notes Mr. St. Cyr
The test will consist of approximately 50 marks as follows:
Matching (8 marks), definitions (8 marks), short answer (8 marks), fill in the
blanks (8), and labeling and explaining diagrams or experiments (18 marks)
You should know what each of the following words mean and be able to give a clear
Pure substances, mixtures, elements, compounds, mechanical mixture,
suspension, emulsion, solution, filtrate, residue, concentration, dilute, solubility, solute,
saturated, unsaturated, supersaturated, acid, base, neutral, litmus paper, neutralization, pH
scale, acid rain, H2O, CO2, NACL.
You should be able to classify models of matter as elements, compounds or mixtures
using nuts, bolts and washers (P. 143).
You should be able to state whether substances are mechanical mixtures,
suspensions or solutions (e.g. P. 147 Table 1 and CYU Q. 2)
You should know the 6 methods studied on how to separate mixtures (P. 148-150).
Picking Apart, Filtering, Using Density, Using Magnetism, Dissolving and
You should know about different filters and how or why they are used (e.g.
colander, sieve, furnace filter, air filter, water purifier, coffee machines, aquariums,
You should know the pH scale and be able to tell whether a product is classified as
neutral, an acid or a base (see P. 162 Figure 4).
You should be able to explain what was done in the 3-part lab on physical and
chemical characteristics of different products (e.g. pH levels of baking soda, dirt,
food colouring, oil, salt, sugar, vinegar and water), separating mixtures from water
(dirt, salt and oil) and mixtures and chemical reactions (water/salt, baking soda/salt,
vinegar/oil and vinegar/baking soda).
You should be able to state what you learned from the activity on testing 2 types of
ink (permanent Sharpie and non-permanent ink from an overhead pen).
You should be able to tell why salt is used on roadways, if it is an environmental
hazard or if there are better alternatives.
