Sugar Rush: Can I Have a Crush?

Overview

Sebastian Ramirez 6th Grade- Pioneer School Abstract Sugar Rush: Can I Have A Crush? The purpose of my experiment was to determine whether adding water reduces the sugar concentration in different beverages, including Jarrito, Sunny D, Apple Juice, and Crush soda. I hypothesized that water would lower the sugar concentration because water contains no sugar and would dilute the solution. To test this, I poured one cup of each drink into separate cups and measured the sugar concentration using a clinical refractometer, which measures sugar in degrees Brix (°Brix). I conducted three trials for each drink to improve reliability. After recording the original readings, I added 25% water and tested again. I then increased the dilution to 50% water and repeated the measurements. The results showed a consistent decrease in ®Brix values as more water was added. All beverages demonstrated lower sugar concentration after dilution. These findings support my hypothesis and show that dilution reduces sugar concentration, although the total sugar remains present in the drink.
