Lego Robotics

This week we have been working on Lego Robotics and programming.  We are building a Lego alligator robot that we are going to program.  This also meant learning the Lego pieces names.  We also learned a bit about a Sphero Ball.  This week has been very robotic!  Mrs. Brown asked me to think about a question I have that I will try to answer tomorrow in class through discovery.  My question is this:  How do people create a program that will control how something works?
