The point value is 50 points.

In assessing your performance, I will be use the followinig rubric

Planning the experiment	Plan is clear, exact, and complete, describing directions and speeds of air flow that will be used for each object.  Students's hypotheses are clearly and specifically stated.	Plan is clear, exact, and nearlyl complete, missing only a few details of direction and speeds of air flow that will be used for each object.  Student's hypotheses are broadly stated.	Plan is fairly clean but incomplete, missing some important aspects of direction and speeds of air flow that will be used for each object.  Student's hypotheses are general or incomplete	Plan is unclear too general.  Student's hypotheses do not address the experimental problem.
Performing the experiment	Student's experiment clearly tests the hypotheses.  Observation are accurate and complete.	Student's experiment tests the hypotheses.  Observations are mostly accurate and complete.	Student's experiment partly tests the hypotheses.  Observations are fairly accurate and complete.	Student's experiment does not test the hypotheses.
Concept Understanding	Student precisely explains experimental results using Bernoulli's principle and thoroughly understands Pascal's principle and density in relation to water.	Students explains experimental results using Bernoulli's principle with minor errors but in mostly correct.   Student has some minor missconceptions of Pascal's principle and density in relation to water	Student partly explains experimental results using Bernoulli's princle but with some errors.   Student has some misconceptions of Pascal's principle and density in relation to water	Student does not use Bernoulli' principle to explain experimental resutls and shows serious misconseptions about Pascal's principle and density in relation to water
