12. Mass  What is the difference between mass and weight?  Mass is different to weight because mass is the amount of matter in an object and weight is the force of gravity on an object.

13.  Set the balance to zero using the adjustment screw.  Place the item on the balance.  Starting with the top beam, slide the rider until the farthest it will move to the right before the balance tips.  Repeat for each rider until balanced.  Add the quantities measured by each rider to calculate the total mass.

19. Density  What is density?  How is density calculated?  What is the SI unit for density?  What is the density of pure water? Density is the amount of mass in a given volume. To calculate density you divide mass by volume. Density = mass/volume We measure density in g/cm 3 or kg/m 3. The density of pure water is 1g/cm 3.

20. Density  Is salt water more or less dense than pure water?  Which is least dense? Solid, liquid or a gas?  Which is most dense? Solid, liquid or a gas?  Which is less dense? Aluminum or iron?  Which is more dense? Balsa wood (used in model building) or oak? Salt water is more dense – the Dead Sea is so dense you cannot sink. A gas is least dense. Ex. Helium balloons float. A solid is more dense than it’s liquid equivalent. Ice water is an exception As the H2O expands when it freezes. Aluminum is less dense. Oak is more dense.
