I'd say science is broadly a label for any attempt to get more knowledge. However some science (or it's results) is a lot more useful than other science, and that's generally that which employs a systematic method, i.e., the scientific method.
Still, burning ants teaches the kid a surprising amount of things:
*how light focuses through a parabola, and the distance of that focal point. later when they learn about the eye or cameras they'll have a visual model as a reference
*how it concentrates the intensity of that light, and that small diameter of sunlight actually has enough heat to burn things. This demonstrates how much power the sun puts out compared to other sources of light
*about the mortal tolerance capacity of ants to heat, and their combustibility
*about the smell of their chitin when cooked, which can give clues to its composition
*about ant behaviour and path selection, and their behavioural response when subjected to heat, or to that of other colony members when barbecued in close proximity, such as threat response, increased speed and in some cases taking the charred bodies back to the nest
*and perhaps an introduction to the ethics of animal testing and intervention in science, should the kid choose to contemplate it
So I reckon it's one of the better science experiments a kid could do
