As usual, I did a little research, because teachers should also be learners themselves. Then we know what it is like to be a student, and we have more information to share with our students as we are learning ourselves. I discovered that this is a marbled orb spider. They spin orb-shaped webs, aren't poisonous (see Kyla, it is okay!), and run away and hide from ladies up on top of roofs who are painting and watching crazy children run out in the street in front of cars.
