I find myself asking that question, although not really needing an answer.
We have been studying hearing, one of the five senses. My son, who was only in public school through kindergarten, has not really studied the human body much. On the other hand, my daughter, who made it through 3rd grade in public school, says she has studied it three times already. So, I am attempting to teach them both at the same time. I try to make it simple enough that my son will understand, and yet interesting enough to challenge my daughter and possibly teach her something new. To take "hearing" into a deeper level, we studied more about frequencies. Not as much as I'd like to and hopefully we'll do more.
So, how did we end up doing an experiment with spices, making homemade "scratch and sniffs"? I couldn't remember until one of the kids reminded me that I read from a book about the five senses, focusing on hearing. But while we were reading, we happened across this experiment and thought we'd give it a try.
I love that about homeschooling. That we can get side tracked and it's ok. In the grand scheme of things, we're still on target, still going to make our yearly goals and yet we took a wonderful side step to do something off schedule and I couldn't even remember how we got there.
