Ionic and Covalent Compounds Properties

In this term now that we are talking more deeply in ionic and covalent compunds, we are reqauire to make an experiment based on the formation of crytals with them. I know for sure that the difference from this two compounds are that ionic compounds are bad insulators and covalent are good, ionic are hard and form crystals and they are good conductors when they are not solid (just dissolve in water or any liquid). And so we are testing which compound will have the highest melting point and conductivity. Also, we are going to proof that ionic compounds make crystals.
