This year I think I did about 10-11 labs in Chem. How can I add more labs next year with getting through the material since it is mostly math based? I seem to have low success with students being able to do labs on their own without asking questions every two seconds, or they can't do the lab and connect it to the material. I want to challenge them but I struggle with balancing lab time and lecturing/practice time. We have 90 min blocks every other day.
