When I started teaching, I told the kids they had the hard part — I expected them to make me feel young(er). I got a good example today which serving as an aide in 8th grade science class.
Have you ever heard of an Oobleck? It’s a non-Newtonian fluid that was the creation of Dr. Seuss in his book Bartholomew and the Oobleck. Bacially, a non-Newtonian fluid acts like a liquid when poured, but a solid when a force acts on it. One of the 8th grade boys did an experiment involving forces acting through a non-Newtonian fluid on eggs, and that’s all I understood. It’s the kind of factoid that keeps me coming back to the classroom.
