So, today I went for a vaccine and my mom took me as I’m a minor and after she was given a questionairre. There was a slot for my gender and instead of checking male she asked if I’d rather tick non binary. I’m cis so this didn’t matter much but it gives me hope that I might be able to come out some day.
I’ve also started teaching my sister critical thinking to prevent her becoming a religious but. Hope she remembers my lesson on questioning authority
I think I remember reading (and maybe math?) workbooks with sections labeled “Critical Thinking” when I was young. So maybe you could go to a bookstore and find the section for workbooks that they usually use for homeschooled children? I have no idea how old your sister is so this might not be appropriate.
I also find exposing people to logical fallacies and common biases often makes a certain type of person eager to identify them in positions they don’t like. If you’re like me, you’re also eager to identify them in your own position so you can root out bad beliefs sooner rather than later. “Smart people question themselves too,” and if your ego cares about being smart, then for some people the egotistical thing, deconstructing your own ideas for errors because I Am A Smart Person And That Is What Smart People Do is also a productive self-check.
She is 5 that’s why I’m struggling to teach
Alongside what others have recommended, I’ve found that running through scientific case examples and trying to get them to come to the conclusion themselves (for example pointing out that a river dips to a certain area or that vegetation in an area is missing) helps to teach critical thinking without a pro or anti-religious bent. It’s also a tad bit of a buzzword today, as it encompasses many skills, but in my opinion (which isn’t the only one) one of the most important base skills is a firm understanding of hypothesis tests.
