Discussion Overview

The discussion revolves around the construction of an oven thermometer from scratch, focusing on materials and methods that can be used to achieve a temperature reading between 250 and 500 degrees Fahrenheit. Participants explore various approaches and materials while adhering to specific restrictions, such as not using mercury and ensuring the thermometer fits inside an oven.

Discussion Character

  • Homework-related
  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests using a bimetallic strip wound in a spiral as a common method for constructing an oven thermometer.
  • Another participant questions the need for a bimetallic strip and proposes using a metal with a high melting point along with its coefficients of thermal expansion and a micrometer as an alternative approach.
  • A suggestion is made to use a thermocouple and a voltmeter as a potential method for measuring temperature.
  • Some participants humorously propose unconventional methods, such as using a Pyrex pitcher to measure evaporation or igniting a Christmas card to determine when the oven reaches a certain temperature.
  • There is a suggestion to look at resources from Omega.com for ideas or to purchase components for the thermometer.

Areas of Agreement / Disagreement

Participants express differing views on the construction methods, with some advocating for traditional approaches like the bimetallic strip, while others propose alternative methods. The discussion remains unresolved with multiple competing ideas presented.

Contextual Notes

Participants have varying assumptions about the materials and methods available for constructing the thermometer, and there are no settled definitions or steps outlined for the construction process.

Who May Find This Useful

This discussion may be useful for students or hobbyists interested in DIY projects related to thermometry, particularly in the context of physics education or practical applications in cooking.

I need to construct an oven thermometer out of scratch using any materials that are purchasable. Our restrictions are:
- No mercury
- The product must be able to read from 250 degrees fahrenheit to 500.
- MUST FIT IN THE OVEN PLZ.
thank you

Is this homework? AFAIK, most oven thermometers use a bimetallic strip wound in a spiral.
 
but we are wondering if you know how to construct it
 
Um... what I said doesn't give you enough information? Is this homework?
 
yep, this is a bonus project for our physics 11 class. any help would be greatly appreciated

Any materials at all? I would start by purchasing an oven thermometer. :wink:
 
Look at www.Omega.com for ideas (You could even buy some of their stuff if you wanted).
 
I don't even think you need a bimetalic strip. All you really need is a metal with a very high melting point, you need to know its coefficients of thermal expansion, and you need a micrometer.

Of course, this is only as a last resort if you cannot create a bimetalic strip.

How about a thermal couple and a voltmeter?
 
  • #11
why don't you buy one and scratch the company's name off and put yours on

First: Construct an oven

Second: Construct a usefull measure for telling if the oven is "ovening"?

Otherwise:
- Buy one?
- Use a pyrex 1 cup pitcher near the door and calculate the rate of evaporation?
- Put a Christmas Card from one of your Ex's in the oven. When it ignites the oven has passed Fahrenheit 451?

Ideas abound...
