📚 Tips for Parents & Teachers
Start with what's visible. If your child can see the moon tonight, start with our Moon Phases tool in the Science section before diving into deep space topics. Connecting digital tools to real-world observations makes the learning feel concrete and personal.
Don't shy away from the mind-bending stuff. Kids are surprisingly comfortable with concepts like black holes and the scale of galaxies — they haven't yet developed the "that can't be right" reflex that adults have. The Black Holes tool is often one of our most-explored tools because kids are fascinated by extremes.
