Computer science and technology for a "non-science" teacher

I'm a brazilian literature and language teacher, I teach kids in the elementary and high school and I really love what I do, but some time ago, before I was selected to work as a teacher for the state, I started studying about programming and technology since I wasn't making ends meet as a private English teacher and I was aiming into a job in the tech field. I started on this road thinking it would be almost impossible for me to understand computing in a deeper level, but then I found out that it was something feasible, actually I was having fun learnign something new (namely I started studying Python and I was peeking into SQL and Data Science before I had to focus on my teaching carreer).

Now that I'm working more closely to kids (many of them from the lower class) I can see that as much as they need basic education they also need to be properly introduced to programming, computer science and actual scientific thinking, otherwise I think they might follow a sort of helpless mentality most of their schools years.

Since I'm not the math or science teacher I think people around the school find it weird that I want to work with that, but I know that these are subjects that can involve and be practiced by anybody in a school comunity.

What sources, books, or projects would you suggest to start working these subjects with the kids?
