I am also a student in college and have been in many different classrooms in which I saw teachers using scripted lessons. Since joining NSTA, I have learned and seen many different ways to make science more fun and engaging for students, in which they can learn at a deeper level. I've found, personally, that it's better for the students and for the teacher if they lesson is written, instead of scripted. Through this I am able to personalize the lesson to the group of students that I am working with and make it specific for their learning needs. As the last reply mentioned, the 5E model, inquiry-based, and hands-on experiments are great for engaging students and support them in higher thinking.
