In this final game in the series of E-field lessons, players progress rapidly through three levels of increasing difficulty. The goal is to feed the hungry dragon lighting strikes. Other charged objects in the world can steal the strikes though, and watch out for the evil birds!

Coulomb’s Law will help players understand the conditions before a lightning strike can occur so they can position the dragon correctly. Each level lasts for two minutes: Level 1 moves slowly with fewer birds; levels 2 and 3 each move faster with more evil birds. Remind students to note their scores after each game play.


***NOTE: This version is an experiment run between congruent and incongruent gestures. Mode A should be played for congruent gestures.

Features + Learning Goals
Students will learn:
  • ·    Introduction of dynamic Coulomb’s Law as a relationship
  • ·    The bottom of the cloud is measured and its changing qnet is displayed
  • ·    This qnet alters with charge separation
  • ·    How their new knowledge of Coulomb’s Law will aid them in positioning the dragon for the maximum number of lightning strikes
  • ·    Lightning requires certain conditions of E-field magnitude and distance to be met
