Course Objectives


 * Primary Objectives- By the end of the challenge the students will be able to:
 * Use the equation P = h x d x g
 * Understand the meaning of each of the variables in the equation.


 * Sub Objectives- The objectives will require that students be able to:
 * Understand the interaction of the density of a liquid with the force of gravity to explain the actual height of the column of liquid that is supported by the atmospheric pressure.


 * Difficulties- Students may have difficulty:
 * Understanding how the units for height, density, and the force of gravity combine to be equivalent to units of pressure


 * Real-World Contexts- Ways that students can use this material in the real world:
 * In an application to or in an interview with NASA for an internship or a work-study program

Assessment of Learning


 * Formative Assessment
 * In Class (groups)
 * Students will assemble into groups
 * Homework (individual)
 * Each student will write a report outside of class incorporating their own understanding of the solution after the work in groups.
 * Summative Assessment
 * An in-class quiz will individually test students over their ability to clearly describe the method of measuring the force of gravity on Mars.

THE CHALLENGE

A group of astronauts takes an experiment to Mars to measure the force of gravity there. They know that on earth the pressure of the atmosphere will support a column of liquid of a certain height. How can they use this concept to calculate the Martian gravitational constant?
