Yesterday some classes took part in an online Science event run by STEM called 'The really Big, Really Small Show. Lots of schools all over the country joined as we listened to real scientists talking about how new prefixes have been developed to describe really big and really tiny things. 

Did you know: 

Scientists are currently making a satellite to enable us measure the weight of the sun

Ronto and quecto  are  prefixes meaning very small 

Ronna and quetto  are prefixes meaning very big (even bigger than mega, tera and giga)

The light of the sun is measured in ronna candela
