Example3: Balance

2.- Volume: the amount of space an object takes up.  It is measured by seeing how many cubes of a chosen size it can fill and it is reported in cubic centimeters.
 

Example: Volume of geometric figures and how to calculate it

Example2: Measuring volume

3.- Density: a measure of how tightly packed matter is; the amount of mass contained in a given volume.  It can be found by dividing the mass of a sample by its volume (grams / cubic centimeter)
 

Example1: Density of liquids

  

Example2: Density of gas

Example3: Density of some substances

  

4.- Buoyancy: the upward push of an object by the liquid (or gas) the object is placed in.

Example1: Buoyancy of a cube

Example2: Buoyancy of human body

Example3: Buoyancy of a bottle

Example4: Buoyancy of a coke can

Example5: General Principal

5.- Conduct: allow heat or electricity to flow through readily.

Example1: Conductivity

Example1: What is conductivity

  

Example2: Conductivity Cell

Example3: Conductivity Tester

  

6.- Insulate: not allow heat or electricity to flow through readily.

Example1: Insulate House Diagram

Example2: Insulate Wall

Example3: Paint to Insulate Roof

Example4: Happy to insulate home
