is it forces you to not rest on your laurels basically of, well, I've got this cool microscope in the lab. I can show to people." You have to then be a lot more intentional about how it is you're trying to design experiments or design activities. And also just know that you are in someone else's domain basically now and you have to be sensitive to what it is that they're interested in, because it's just not going to make a lot of sense if you come to an event and you bring something that's way out of left field and they're like, "What is this? Why are you doing this?" Unless you're doing it because they ask for it because they think it's interesting because the kids showed interest. So at least it shakes you a little bit and it reminds you that you got to be a little more intentional than you may have initially thought if you were just bringing somebody to your lab.
