Holla Sonia,
and welcome in the gang.
I appreciate your drawings. In the mean time, as you are in sciences, there is a place, here on Steemit, where you might be interested in sharing your knowledge: @steemiteducation
Have a look.
By the way, I am a mechanical engineer and a secondary school teacher (Maths and science) hence, a pedagogic engineer; maybe we will find a common ground for exchanges on how sciences help us, or not, to understand our reality.
