Beyond the Fizz – How to Get Kids Excited About Doing Real Science

No one cared that it was cold outside. These kids could hardly wait to see what would happen next. Giggles and laughter bounced from child to child as the group of second graders positioned themselves around the 2-liter bottle of diet soda.

In a whispered voice, one boy asked, “Do you really think she’s going to do it?”

“Sure… she’ll do it, but you have to get ready to run,” replied the girl standing next to him.

Mrs. Schmidt removed the roll of Mentos mints from her pocket and loaded them into a small tube that attached to the top of the soda bottle. The only thing that kept the Mentos from falling into the soda was a plastic pin tied to a piece of string.

Third grader Jack Liebold took this question on for his science fair project. The problem? How do you test helmets without using real crash test people? Easy. He used honeydew melons to use the scientific method and test his hypothesis.

Jack joined me during my weekly newscast experiment on 9News to share his results and how he conducted his experiment.
