Hello, @sco, great to have another scientist on board! Your post ideas sound great, I might only recommend that you use the #steemstem tag when you post your Science-related content to give it more visibility and make it easier to find by the science curators who promote quality content.
We have a very nicely growing and supportive science community here on Steemit, so feel free to interact and reach out! We are all connected :-)
Cheers, and welcome! Have fun.
