Materials and Methods
Read all instructions first
*IMPORTANT- LAB SAFETY*
Wear safety goggles at all times!
Ensure that all waste goes into the labelled waste beaker for each station.
Acids are corrosive!!! Make sure that you tell your instructor if you come into contact with acid.
Immediately soak that area with water.
Use caution when working around open flame – ensure long hair is tied back and tuck in your tie

Methods
Physical properties
STATION 1 – Wood and Brass
Make observations about the physical properties of each. See and fill in Table 1.
STATION 2 – Water and Syrup
Make observations about the physical properties of each. For the viscosity test, you may use the second
beaker to pour the water or syrup. Do not mix the substances. See and fill in Table 2.
STATION 3 – Conductivity of water, iron, and graphite (THIS WILL BE DEMONSTRATED)
See and fill in Table 3.
STATION 4 – Aluminum foil and dried pasta
Make observations about the physical properties of each. See and fill in Table 4.
STATION 5 – Water, oil, sugar, sand.
a) Rock the water bottle back and forth and record your observations about the solubility of water and
oil. DO NOT OPEN THE LID. See and fill in Table 5.
b) Add a small scoop of sand to the flask, close with the rubber stopper. Shake for 1 minute. Record
your observations about the solubility of water and sand. Pour the mixture in the waste beaker B) and
rinse the flask with tap water. See and fill in Table 5.
c) Add a small scoop of sugar to the flask, close with the rubber stopper. Shake for 1 minute. Record
your observations about the solubility of water and sugar. Pour the mixture in the waste beaker C).
Rinse the flask with tap water. See and fill in Table 5.
Chemical properties
STATION 6 – Baking soda and vinegar
i)
ii)
iii)
iv)
v)
vi)
Using the graduated cylinder measure out 10 mL of vinegar and transfer it to the beaker.
Record three physical properties about the vinegar.
Record three physical properties about the baking soda.
Using the scoopula, add a small scoop of the baking soda to the beaker.
Observe and record in Table 6. Describe the physical properties of the resulting mixture.
Place the waste in the waste beaker. Rinse out the beaker with tap water.
STATION 7 – Combustion of paper
i) Obtain a small piece of paper
ii) Record three physical properties of the paper in table 7
iii) OVER THE METAL TRAY PROVIDED, hold the piece of paper in the tongs and light it in the
flame of the “tea-lite” candle *STAY WELL AWAY FROM THE FLAME KEEPING IT
ABOVE THE METAL TRAY AT ALL TIMES
iv) Record three physical properties of the substance formed after the paper has been burned (in table
7)
STATION 8 – Cooking spinach
i)
ii)
iii)
iv)
Obtain 1 leaf of spinach
Record three physical properties of the spinach in table 8
Place the spinach in the beaker of hot water for 1 minute
Using tongs remove the spinach from the beaker of boiling water and place it on the paper towel
provided *Be careful it will be hot!
v) Record three physical properties of the cooked spinach.

2) Based on your observations, how could you identify that stations 6, 7, and 8 tested for chemical
properties. (i.e. what observations indicated that they were chemical properties; see your introduction).
Consider each experiment.
