Hi I work in a Junior School. Love the junior school aged children and science. Their natural curiosity lends itself so perfectly to investigation, questions and some great and funny answers!
In the past we have used Chris Hadfield and his posts about life in space as a great ‘real life’ as a concrete example of how gravity makes life in space and on earth so different! How gravity helps us on earth, but also how fun zero gravity would be. The children loved this and enjoyed finding comparisons and coming up with their own ideas of inventions to supports them if they were on the space craft with Chris!
