"Alexa.... what is geography?"

My colleague in the IT room has an Alexa to use for teaching IT - and it is used in various ways.
There is also one installed in the school's learning support rooms to allow pupils to check spellings, and provide other help. Such devices are called 'home assistants' (but do they also have a place as 'classroom assistants'?)
I will be exploring this over the Christmas period, and will put together some ideas for using them in the (geography) classroom and share them here in the New Year...
