I would not wait to address this, just because it's her first time doing pull-outs. In fact, I think the earlier you catch this, the better. She may be more amenable to friendly, helpful feedback at this stage. I would make it clear that I expected science pull-outs to contain actual, you know, science. Depending on what the topic is supposed to be ("textures"? huh?) you could suggest a project that explores friction and how it affects how an object moves across a surface; or how our fingers detect different kinds of textures. Keep it friendly and light and helpful at this stage.
