I. Calculating mass, volume and density

a. use the dmv triangle to determine which equation to use

b. plug in the known values

c. solve the equation with proper units of measure (mass in grams, volume in cm3 or mL, and density in g/mL or g/cm3)

II. Definitions

b. density

c. volume

d. meniscus

e. Archimede’s Principle

III. Density of water

a. will and item sink or float based on mass and volume

IV. Buoyancy

b. positive, neutral and negative buoyancy (what that looks like for a submarine or for a hot air balloon)

V.  Determining the volume of objects

a. By weighing on a digital or triple beam balance (liquids in container)

b. By displacement of water (solid objects)

VI. From Last Exam
