What happens to sugar molecules when they dissolve in water?

• They disappear forever into another dimension.

• They break into smaller molecules.

• They spread evenly in the water.

• They turn into candy rainbows.

What is one way to separate immiscible liquids?

• Use a magnet made of cheese.

• Heat them until they magically mix.

• Let them settle into layers.

• The solvent evaporates into glitter.

• The solute and solvent mix more quickly.

• The solute grows wings and flies away.

• Solubility is the ability of a solute to dissolve in a solvent.

• Solubility only applies to liquids that sparkle.

• Solubility decreases when you stare at the solvent.

Scientists often use models because:

• Models are easier to see than very small or very large objects.

• Models are identical to what they represent, down to the atoms.

• Models replace experiments with magic.

• Models are always invisible to everyone.

Which of these shows evidence that a solution is saturated?

• The solute forms a layer at the bottom.

• The solution sings when it’s full.
