Students are to read a literature book about how inventions can be used or abused by people. .


Bartholomew and the Oobleck is a story about a king who wanted to have something fall from the sky that was "his." He complained to Bartholomew, his page, that he wanted the magicians to invent something for him.

The king is happy with the new invention of Oobleck until he realizes that the Oobleck is not good for his kingdom. It is Bartholomew who convinces the king the only way to stop the mess is for the king to admit it was his own fault that this happened.


  1. After you read the story, discuss what this strange substance could be. It is definitely a strange substance that comes from the sky. If you put a little green food coloring in your starch mixture, you have some oobleck!
  2. The moral to the story is that "not every invention helps people, inventors must be careful!"
