We watch the video To Scale: The Solar System (https://vimeo.com/139407849) and take notes. Everybody brainstorm one word and put them in order according to their size.
We want to describe these words comparing them to each other but since we don’t exactly know how to make comparisons in English, we watch a video that explains it: Comparative Adjectives https://www.youtube.com/watch?v=wXiD0FdON7k and another one to check that we have understood it: Quiz – Comparative and superlative adjectives https://www.youtube.com/watch?v=pm9fq1MbR_I.
We also write 5 sentences using 5 different adjectives to describe the planets in our system: S.Siarso.
