This is an embodied refresher on the fact that vectors possess both magnitude (length of arrow to be drawn) and direction (which direction the arrow is pointing).  Embodying, or drawing, these vectors on screen helps students to understand how charged atoms can either attract or repel each other. 

The game is scaffolded so that players first observe 2 vectors drawn, then trace 2 vectors, and then generate 4 scored trials.  With multiple incorrect trials, prompt hints begin to appear.

Features + Learning Goals
Students will learn:
  • ·    Vectors have both magnitude and direction
  • ·    How to draw, in an embodied manner, vectors on the computer
  • ·    Charged atoms can be either attracted to or repelled from one another
  • ·    The motion of the charged atoms can be represented by vectors (in non-quantum mechanics )
  • ·    The movement is according to Coulomb’s Law (relationship displayed)
  • ·    How dynamic Coulomb’s Law is
