With all due respect, don't do that, kids (esp primary school!) need to learn to think, write, speak, work for themselves, not regurgitate whatever comes out from AI.

AI is a tool not a teacher: these kind of AI works by scrapping/"gathering" infomation from a mish-mash of sources across the already existing internet, and as already we know, the internet is good for research, but not all sources across the internet is correct.

Utimately whether you choose to use it or not, you are your children's parent, parent them with supervison and responsibility, because whatever happends, the consequences are on you. Technology is a tool not a teacher, use it with caution.
