Answer Questions Below 1.Constant in experiment: Variable in experiment: 2. What type of sugar dissolved fastest? Why? 3. What type of sugar dissolved slowest? Why? 4. If the sugar particles where larger would that make a difference? Explain 5. Why should you thoroughly chew your food? 6. Explain how reducing the size of food particles aids in the process of digestion.

Answers to Questions 1. Constants: size of beaker, temperature of water Variable: size of sugar particles 2. granular sugar dissolve fastest, smallest in size, least amount of surface space 3. cubed sugar dissolve slowest, largest in size, most amount of surface space

4. yes, the larger the particle; the longer it takes to dissolve 5. Smaller sized particles dissolve / digest quicker 6. To be used by the body, foods must be broken down and dissolved into nutrients. Once digested, the blood carries these nutrients to all the cells of the body.
