I’ve heard these criticisms, too. In our case, there really is no option other than to do it ourselves. Our community college costs, and while it’s cheaper than four-year college, we don’t have the money. And there are no homeschool groups near us anymore and as far as I know, no other high-schoolers except a few in the school-run HSAP (not an option for us, we are HSLDA members). So I have a feeling there are many other homeschoolers out there without free options.
I think my kids have done more “real” experiments than I ever did in school. We were always paired up or more, and I usually deferred when possible to someone else. I specialized in the “book” stuff and the equations, so I “advised” on the actual experiment work.
It’s not always cheap or easy to do them at home, but we’ve managed. We have done some labs through a company that will advise if we are not getting the result we want (Quality Science Labs) and some we’ve done on the cheap on our own, and had to really work to figure out how to do it right. But in college, we did labs with very little actual supervision, and I think the process of really having to work, troubleshoot, etc. will be valuable for them at that time–college labs are much more independent.
