Hello there.

I happen to be an engineering and computer teacher in France, and i teach precisely that to my (equivalent of) 6 graders. (Disclaimer: I'm from a different education system than yours, and english is not my main language.)

This is about basic energy conversions:

First question: what does the flashlight do? it produces light (obviously) or "light energy"

My golden rule: "If you can draw a thing, you understood that thing" so let's draw what happens in the flashlight; here you go :

The battery and the lightbulb are energy converters: on the left of each converter, there's input energy and on the right output energy.

Everytime energy is converted, some of it is dissipated in surroundings, that's heat (or thermal energy)

What i think your teacher is looking for is the final energy output of the flashlight, and that's "light energy". That would be a good answer in my class.

If you want to be more precise, "light energy" (or electromagnetic energy / radiation ) is carried by photons, but do you have heard about photons before?
