Too Cold Today

As I sit here from home today and look at the temperature gauge outside hovering at -4˚F right now, I can’t help but think about positive and negative integers! Of course temperature is a great way to introduce and work with negative numbers, but true negative temperatures don’t occur all that often, even in cold parts of the country like Ohio. But they will occur more often if we use Celsius instead of Farenheit! Using Celsius will help students in science and when they travel outside of the US. It is nice to be able to have an intuitive understanding of what 25˚C means without having to do conversions. The best way to understand something is to experience it. Those of us who use Farenheit know that 72˚ is very comfortable whereas 50˚ is pretty chilly but not too cold. Usually we can estimate the temperature within a few degrees and that is good enough. So having an idea that 2˚C is cold and 40˚ is pretty hot will come to students better if they do this every day. A weather station with even just a thermometer where students record the daily temperature in Celsius can help with that. It can also be used to do data analysis and graphing as the data is collected over the months and years.
