Okay,
Under normal conditions things contract (get smaller) when cooled and molecular motion slows down.
Water is an exception because of the behavior of of its molecules as they form ice crystals.
The fully formed ice crystals take up more space than the liquid mloecules that originally formed them. this is why water expands as it freezes.

Cold is just the absence of heat. So, if you can visualize a pot of water boiling on the stove, the electrons are zipping around like bees around a hive, but on steroids. Mostly the O's; the H's are just too laid back. And when things cool down, the electrons get to a point where they can't overcome the temperature, and thus are incapable of movement, somewhat like most Americans after having gorged themselves on Turkey Day.

neither ... water is weird that way... if they got closer (as other elements do), ice would not float on the surface and fish would be frozen solid during winter.
the elements get smaller as they slow down and get colder. Because elements do this, I would agree with your daughter. The electrons slow down and spin closer to the nucleus. The atom takes up less space then

Matter exhibit 3 different states Solid,Liquid and gaseous. The Reason for 3 different states of matter is the molecular interactions.If they are strong then substance will be solid and if weak it will be fluid. As the temperature increases the molecules move randomly (thermal agitation) and this leads to change of state.

the water expands and the particles line up in rows like this:
oooooooo
oooooooo
oooooooo
oooooooo
they are not jumbled like a liquid (in its H2O) form:
0o o o o
o o o o o
o ooo oo o
o 0 o o o oo

When water freezes particles expand.

They get closer because when they are heated they expand

water expands when it is frozen. Its how it breaks pipes when they freeze in the winter :D
