Has your daughter actually thought of concrete reasons why the labs take so long and then asked the professor about it? The vast majority of students in labs I took would have stayed longer if allowed to, but that doesn’t mean the lab was inordinately long. Sometimes, students who aren’t comfortable with lab work take long for many different reasons. What are your daughter’s reasons? If they are out of her control, she should speak to the professor. If they are in her control, she should still talk to her professor to discuss strategies she can try to reduce the amount of time she spends in lab.
The point of the class is for her to learn about these new topics. If she’s taking so long on the lab reports because she doesn’t understand the material, then that’s a different issue. What materials does she have to prepare for to prepare for the lab? In my experience, you should know most of what you’re going to write in a lab report by the time you finish the lab. Trust me, as someone who has been there, done that, writing a lab report for a class is not harder than producing a publishable paper for a well-respected journal.
