For my spread, I would like to discuss Galileo's house arrest. Though he still lived a fairly easy life, not being allowed to leave the house must have been incredibly difficult.
I think this is important because it is easy for children and even adults to think about scientists as the dead men they are, and gloss over the actual sacrifices made. In Galileo's case, the sacrifice is massive: he gave up a normal life because he so strongly defended his work. Even though this would have driven some men to insanity, Galileo continued to publish works even in his state of arrest. He would spend the rest of his life in his villa in Florence. It would take the Catholic church almost 300 years before
I think kids could easily grasp his isolation and solitude. Ilustrations could include Galileo sitting alone in a massive room, working on his next work. Another possibility could be some sort of info box listing other famous men and women of science who became (for lack of a better term) martyrs for what they believed in.
Another illustration could be that of Pope John Paul II declaring Galileo innocent in 1992, saying,
"Thanks to his intuition as a brilliant physicist and by relying on different arguments, Galileo, who practically invented the experimental method, understood why only the sun could function as the centre of the world, as it was then known, that is to say, as a planetary system. The error of the theologians of the time, when they maintained the centrality of the Earth, was to think that our understanding of the physical world's structure was, in some way, imposed by the literal sense of Sacred Scripture...."
