You may be too far into stoich at this point, but you may be able to adapt some labs to kitchen materials. For limiting reactants you could have them make smores and determine what the limiting reactant, excess reactant, and theoretical yield are. Usually I do this with teddy grahams, mini marshmallows, and chocolate chips but you could also have them choose anything they have handy to demonstrate the concept. Since we're all masked up, I'm going to do something similar with nuts and bolts.
I've also heard about colleagues doing a lab live but with students instructing and asking questions. I think Paul Anderson of Bozeman Science posted about it last spring.
