How to Talk About This Term with Young Children
Since you often can’t see gas, it’s hard to talk about it! Encourage children to notice the wind in the car when the window is down, or the air pushed by a fan. “Do you feel that? You can’t see it, but you’re feeling gases being pushed around!” You might also bring attention to steam when cooking, since it’s easier to see.
