#3 Flow rate lab
concept  For an incompressible fluid experiencing nonturbulent flow, the volume flow rate through a tube of flow must be constant  no fluid can be created or destroyed, the total amount passing any xsection of the tube in any second of time must be the same. In equation form, this can be expressed as A1V1= A2V2. 
Equipments  tubes or faucets with various radius water stopwatch 
purpose  students compare both the measured and calculated velocities and flow rates for different tubes or faucets.

#4 Buoyancy lab
concept  The buoyant force is defined as being EQUAL to the WEIGHT of the displaced fluid. 
Equipments  table clam pendulum clamp hooked cylinder beaker water ruler 
purpose  Students explore how buoyant forces affect the different mass and to graphically determine the buoyancy force and density.
