Question
What is a thermometer?
Sketch a thermometer and briefly describe how your thermometer works.
Build a Thermometer• The objective of this lab is to
o design, o build, o calibrate, and o test a thermometer.
• Design Plan due -------– This includes list of materials needed. Feel free to discuss your ideas with instructor during your planning stage.
• Lab construction – --------• Report Due ---------
Steaming Boiling Warm Cold
Design Plan Uses a unique method that is easy to follow and includes trouble shooting suggestions.
Method is complete and easy to follow
Essential steps are there for someone else to replicate
One could not follow this method and make a thermometer
Documentation of work
Description of concepts considered in design and recorded all information as outlines in “Lab Notebook” instructions. Reports the range of thermometer.
Recorded all information as outlined in “Notebook” instructions. Reports the range of thermometer
Recorded essential information with little detail
Sketchy documentation
Calibration of Thermometer
Calibrates, tests, and measures accuracy.
Calibrates with at least 3 repetitions
Provides a scale No reliable calibration
The test!
Measure environment specified by Instructor within 0.1 C
Measure environment specified by Instructor within 1.0 C
Measure environment specified by Instructor within 5.0 C
Measure environment specified by Instructor within 10 C or not all all
Rubric for Report Exemplary Very Good Needs Work POINTS
AWARDED
POINTS 3 2 1 Introduction Clearly states the goal
that Good statement goal but lacks clarity.
Poor statement of goal
Literature Review Minimum one page of background information that explain the principles on which your thermometer is built. Includes principles such as coefficient and kinetic energy
Minimum one page of background information that explain the principles on which your thermometer is built.
Doesn’t fully lay the foundation for the design.
Materials and Methods
Complete enough to understand how the lab is done without getting into too much detail. Includes method of calibration
Can understand how the experiment was conducted but not clearly stated. General calibration described
Too much detail or insufficient detail to obtain a clear picture of how the experiment was conducted. Little or no calibration information
Final Sketch or photograph of Thermometer
Calibration Data
Good use of results, data or observations to explain range and uses of your thermometer.% error
Calibration not replicated and very large % error
No calibration or % error reported.
Conclusions:How well did your
thermometer work?
Clearly report the usefulness of your thermometer, error analysis, and suggestions for improvement
Some report of the usefulness of your thermometer, error analysis, and suggestions for improvement
Lack of report of usefulness of your thermometer, error analysis, and suggestions for improvement
After Building and Calibrating
• Students make a presentation to the class to share their thermometer.
What is Temperature?
• Now that you have built an instrument to measure temperature, how would you define temperature?
Temperature Basics
• Temperature of an ideal gas is directly proportional to the average translational kinetic energy of the molecules of gas.
• Temperature is important as it provides a way to measure the thermal radiation of an object

What is the difference between heat and
temperature?Place your hand on each object on the table and then arrange them in order of hottest to coldest.
