It would be helpful to know what science lab course this is. Some are more time consuming than others. It would also be helpful to know what year the college student is. My kid says that the higher level courses had a higher level of work, written assignments, and difficulty of labs.
In any event…the parent really can do nothing about this. If this is really an issue for the student, the STUDENT needs to talk first to the lab instructor, second to the course professor, and third to the department chairperson.
Otherwise, this is complaining for the sake of complaining. They could drop the course if it’s that much work. See if they can take it elsewhere, or with a different professor. But…it might not end up being less work.
