How Does Sugar Effect Focus And Brain Functionality?
Middle School/High School
Difficulty of Project
$10-$100 depending on number of participants
Possible safety issues. Make sure none of the participants are diabetic.
Easily available from the internet or library.
Approximate Time Required to Complete the Project
At least a day.
To understand how sugar effects brain chemistry.
Materials and Equipment / Ingredients
- An IQ test
- A test of focus
There has been much debate over how sugar affects the minds of young people in America. Sugar has been banned in schools in Palo Alto, and in New York. Is sugar actually causing children to be hyperactive and ill attentive? Or is sugar improving their attention span and their IQ?
- How does sugar affect a person’s IQ?
- How does sugar affect a person’s focus?
Terms, Concepts and Questions to Start Background Research
- How can you test focus?
- How can you test IQ?
- What is the effect of sugar on the brain?
- What is the average amount of sugar that Americans eat every day?
- Find a group of participants for this study.
- Divide this group in two. Tell both groups to track everything they eat for an entire day. a. Instruct Group A to eat nothing containing sugar. b. Instruct Group B to eat anything they want, as long as they write it down.
- After a day of eating only the allowed foods, ask each participant to take an IQ test and a test of focus level. Also, ask for the list they have made of what they ate. a. Calculate the sugar levels in all the foods on the list. b. Score the IQ test and the test pertaining to focus levels.
