Mini-poster assignment:

• Draw the outline (like a coloring book picture) of a solid, a liquid, and a gas

• Label the objects –  solid, liquid and gas

• Fill in the objects with circles that represent how the molecules behave in each state (just like we drew in our notebooks for class notes)

  Earn 6 points toward a low lab or homework score; 1 point for each drawing with correct molecule depiction, and 1 point for each label.

Here’s an outline of what you need to study:

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

a. mass

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

a. definition

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

a. Steps of the scientific method

b. Lab equipment

c. metric prefixes

Oh, I need to do this in my class next time I teach density!
