Could It Be A Trilobite’s Descendant?

Could it be? Was this “bug” walking through my living room a remnant of the trilobite species? I’d seen pill bugs before, but this bug looked to have LOBES! And three of them at that!

The child inside of me was beyond excited, thrilled…not quantifiable. I hopped onto Google (of course). There I found a TON of info and began to learn so many new things.

I started by searching with the only terms I knew: “roly-poly bug” and “pill bug”. I learned that people all over the US called them by different names. And there were a lot of different species with a wide variety of markings. It was the pale markings on my bug that made it appear to have lobes, which it really did not.

Next, my husband announced that it really couldn’t be a trilobite because all the known species were “assumed” to have lived in water. So I dug a little deeper. Lo and behold, the pillbug, roly-poly (or even sowbug) is not an insect at all…it’s a crustacean! It has gills! I will forever remember these last facts because they are unique, unexpected and the opposite of what I thought I was observing: an insect. But this guy has 7 pairs of legs…and those GILLS!

Why is this so fascinating? I believe I had a childlike moment of learning, something all us teachers hope to inspire. And brought on by a tiny little bug.

You see, this example had all the elements of what we teachers need to inspire learning:

  1. A Eureka moment in which I was driven to figure out if this could really be a unique species of trilobite.
  2. A novel learning moment in which I learned that this “bug” was no insect; rathe a crustacean with 7pairs of legs, and GILLS!
  3. Comparable/compatible information that helped me understand my curiosity: besides looking like a trilobite, they also behave like a trilobite. When they are moving, their little legs hold up the “shell” and when touched, they roll into a tight ball.

All in all, it was a perfect (personal) example of what great learning can be.

What sort of amazement will you inspire in your students today?
