I learned this a couple of weeks ago when I was assembling a series of web-pages urging people to experiment and measure their efforts at vermicomposting.
Suddenly realized that "experiment" means white lab-coats and Bunsen-burners to most folks in the domestic market. And who wants to invest in a set of gram-scales, count worms by hand etc?
"I just want to have the worms eat my food scraps".
Abandon the words "experiment" and "measure" and use the one word "observations".
Anyone can observe; I mean, that's just using my eyes, right?
And it's not a problem to write down, in my own words, what I have observed ...
