Up to now we have been covering a lot of things beginning with the letter 'C' – computational thinking, coding, conditional statements and today’s ‘C’ is Celsius.

Remember the micro:bit has lots of built-in sensors including a temperature sensor. Temperature is a measure of how hot or cold something is. It is normally recorded on a temperature scale and there are two common scales: Celsius and Fahrenheit (e.g. 37°C or 37°F).

In Ireland, we tend to use the Celsius scale which is named after a Swedish man, Anders Celsius. The micro:bit also uses the Celsius scale so when it displays a number that is temperature, for example 18, we should note that as 18 °C. 

Challenge: Research the differences between the Celsius scale and the Fahrenheit scale. 

Having a device that can monitor temperature can be very useful for lots of reasons. But the focus of this episode is to think about how it can be useful to monitor temperature in our homes. The reason for this is that a lot of homes waste heat energy every day. This isn't good and for us to live more sustainably, we should really be more efficient with our energy.

So, time to get going with all the C’s: Let’s computationally think and make Celsius a part of our conditions as we continue to code!
