Play with patterns. Play with sets. Go outside and throw rocks and pay attention to the paths they travel. Drop stones into a pond and watch the ripples. Figure out why buildings don't fall down- or why they do. Ponder why the wind off Lake Michigan travels through the city of Chicago the way it does. And Oklahoma, where the wind comes sweeping down the plains... what's different in very windy places? How do you need to change things to accommodate that? Or other weather? Why are most of the roofs in places that get a lot of snow not flat?
I could go on and on and on and on. You can, too.
Question everything. Figure some of it out.
