"I love our snowman... and look it's snowing!"
"It's just science!"
"I love it too, but I have a question, why does snow fall down from the clouds instead of up?"
"The snow is falling down on Earth from the clouds because of a force called gravity. This force pulls everything down towards Earth, including rain and snow."
"That's cool! I think I've learned about that before."
"Here I made hot chocolate!"
"Thanks! Speaking of science! That spoon in the hot chocolate is fluid friction!"
"That's really cool!"
"How?"
"Objects, like my spoon, move through liquids, like the hot chocolate."
"The movement of the liquid resisting the solid object is friction, this is called fluid friction."
