Lecture Topic: Gravity and Atmospheric Pressure

Instructor: Frank Dean

Institution: The University of Texas Pan American

## Backwards Design

edit**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

**Model of Knowledge**

**Concept Map**- Predicting the height of a column of a particular liquid supported by atmospheric pressure
- Identifying the device that can be used to measure atmospheric pressure
- Identifying how the device will be used to measure atmospheric pressure

**Important to Do and Know**- Review the calculation for the pressure exerted on a column in the atmosphere
- Review the density of various liquids
- Review the reason for the units associated with the force of gravity

**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.

- In Class (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?
