Coloring Book Demonstration -- $9.75

  

Concepts Taught:

  • Scientific inquiry/discrepant event
  • Acid-base indicators
  • Biological stains

A coloring book with none of the pictures colored is shown to the students. Suddenly (i.e. after the teacher sprays the cover of the book with acid), the book is opened and the students see that all the pages are colored! Finally, the teacher closes the book and sprays bleach on the cover. Again the book is opened to reveal that all the pages are completely blank.

Demonstration can be performed over and over again. Your students will be amazed!
