Ah. My school didn't separate labs and lecture...if you took the course, you had to take the lab. I'd say that 90% of the science courses had lab, half of the psych courses had fake-lab (which they were adamant on the attendance of), and all of the CS courses had a 'lab period' which you could usually manage to slowly stop going to halfway through the semester if your programs were good.
That being said, most of them were pretty awesome. I took the advanced orgo lab where at the beginning of the semester they gave you 2 reactants (unknown) and the steps to make a product. There were no lab manuals or procedures, and your job was, as a group, to design the experiments and tests needed to solidly demonstrate the exact structure of both reactants, as well as the final product, and describe the mechanism of the reaction. We had access to every instrument in the college, a limited budget for send-out labs and for ordering new chemicals for testing, and weekly meetings where the prof would tell us whether our reasoning was sound, but refused to give us any hints other than "if you do that you will blow things up" or "there is no way you can prove THAT structure from those NMR spectra" or "sure, if that's what you want to do I'll show you how to switch the NMR over to a fluorine probe".
Most of the other classes required designing your own project for the final weeks, which I liked. In my Micro lab, instead of using species known to the prof, she literally gathered a soil sample, used that as our source, and said 'I cannot guarantee there are no pathogens, be careful'. I ended up finding some unnamed species from a rare genus with only 7 previously studied strains. It was pretty neat!
But yeah, downside was that I rarely had a semester with only 1 lab.
