Does the amount of salt affect how quickly ice will melt-science for kids?

Yes, water's melting point is the way it is because of the types on intermolecular interactions between them (hydrogen bonds) and the geometric shape that it forces water to have when solid. Adding salt would lessen the amount of those types of bonds in a glass or whatever container you're using and the types of interactions water makes with salt molecules are comparetivly weaker (ionic bonds), akin to 'getting in the way' of what would have been a more ordered structure, which is ice.
But adding salt doesn't substantially warm water so a mixture of water and salt can be zero degrees and liquid whereas pure water at zero degrees in our atmospheric pressure will always be ice.
