Tomorrow will be a scorching 35° outside! How often have you heard a meteorologist utter these words? 35° can sound scorching if you’re from Norway or Sweden, but here in the United States it is actually quite chilly. 35° Celsius is approximately 95° Fahrenheit. The United States still measures temperature in Fahrenheit while many other countries are using Celsius. If your students completed this week’s Iditarod Trivia Tuesday, they found out there are 13 mushers from countries other than the United States signed up for the 2015 Iditarod. Converting temperatures is a quick and easy lesson aligned with the Common Core.

To grab your students’ attention right off the bat, reveal tomorrow’s temperature to them in Celsius. This can easily transition into a discussion about how the U.S. uses Fahrenheit while many other countries use Celsius.  This can lead directly to students discovering which countries the 13 mushers from out of the USA call home.

In this lesson students will identify Iditarod mushers that are not from the United States while making real world temperature conversions such as, boiling water, freezing water, body temperature, etc. Students will also develop a week-long weather forecast for their hometown and a village on the Iditarod trail. The weather forecast must be accurate according to the weather app the students choose. While developing the forecast they must also convert the Fahrenheit temperature to Celsius.

The sixth grade students at Camanche Middle School, where I teach, report the weather daily at the beginning of the day. I am going to challenge them to start reporting the temperature in Celsius. This will require reporters to convert the temperatures and encourage the listeners to convert the temperatures. Good luck converting temperatures.
