About "Ask A Scientist!"
On September 17th, 1998 the Ithaca Journal ran its first "Ask A Scientist!" article in which Professor Neil Ashcroft , who was then the director of CCMR, answered the question "What is Jupiter made of?" Since then, we have received over 1,000 questions from students and adults from all over the world. Select questions are answered weekly and published in the Ithaca Journal and on our web site. "Ask A Scientist!" reaches more than 21,000 Central New York residents through the Ithaca Journal and countless others around the world throught the "Ask a Scientist!" web site.
Across disciplines and across the state, from Nobel Prize winning scientist David Lee to notable science education advocate Bill Nye, researchers and scientists have been called on to respond to these questions. For more than seven years, kids - and a few adults - have been submitting their queries to find out the answer to life's everyday questions.
Another possibility is that parents who believe that sugar makes their children hyperactive only allow them to have sugar for special occasions, such as birthday parties or family gatherings. These are occasions where children tend to be somewhat excited and active anyway. Then when the parents see their children being very active and excited, they think that it is due to the sugar. But regardless of the reason for people's erroneous beliefs about this, it is quite clear that sugar does not produce hyperactivity, even when researchers have specifically focused on children with a presumed "sugar sensitivity".
