Charts and tables are tools we use in science to break down information analytically and present data in an organized manner. It is a beneficial strategy for learning about and organizing scientific material, which we will be using often in this class. Make sure that you are detailed, thorough, and specific in your responses. Explain yourself clearly. Do not list a word or brief phrase without explaining what it means. For example, if you list diabetes for carbohydrates, make sure you explain how carbs are associated with diabetes. Don't leave the reader to make that connection for you. Also, make sure you provide APA-style references for each of your so
