Celsius and Farhenheit

Objective: Compare celsius and fahrenheit.

A simple starting point in comparing celsius and fahrenheit scales is to have the student take their temperature. If you have a thermometer that registers in both celsius and fahrenheit, check both.

Explain that the average temperature for humans is 98.6 F or 37.0 C.

To gain practice using both, check daily climate temperatures in both fahrenheit and celsius scales. Have them estimate the temperatures before checking them.

Boiling Point of Water

Here is an experiment to check the boiling point of water. It works best if you have a thermometer that measures both. You could also use two seperate thermometers. Students should realize that the boiling point of water is 212 degrees F or 100 degrees celsius. Point this out on the Celsius to Fahrenheit Matchcard.
Compare that with the fact that the human body temperature is 98.6 degrees F. Consider how confusing it would be if you mixed up the two scales.

Freezing Point of Water

It's a little trickier to test the freezing point of water. Here is how to do it: Students should learn that the freezing point of water is 0 degree F or 32 degree C. Point this out on the Celsius to Fahrenheit Matchcard.

Let's Think About It

Which scale is easier to use? There is no right or wrong answer. But the students should ponder the implications of the two different scales.

Take It Further

Explain that every substance has its own boiling point and freezing point. Those points are different for different substances. You may want to repeat the experiment and use other household liquids. Also note that all substances have a freezing point and a melting point. For some substances, those temperatures might be too extreme for us to experiment on a kitchen stove or freezer.

A Tasty Twist

You will likely get no complaints if you take your freezer experiments a bit further and make homemade ice cream. The directions are also on the Celsius to Fahrenheit Marchcard.
You might want to save a little of the final mixture to experiment on the boiling point of ice cream. But don't be surprised if there is nothing left.

Learning More

The Condensation MatchCard (Light and Energy-6) will take some of the temperature concepts from the Celsius to Fahrenheit Worksheet here even further.

Also, use the mathematical formulas to convert back and forth between the celsius and fahrenheit scales. Older students (7th grade and above) should know this formula. Younger students should be aware that it is available for use. The information pieces for the formula are on the third page of the Celsius to Fahrenheit MatchCard.
