Simple Sugars Test for the presence of monosaccharides Must use liquid samples Use water to moisten sample with mortar and pestle Use hot water bath for 5 – 10 minutes

Benedicts Solution

Likert Scale

Controls Positive Control – definitely will be a YES Negative Control – Definitely will be a NO

Safety

Complex Carbs (Starch) Can use on a solid food item Use a spot plate Small pieces of food 2 – 3 drops lugols

Log Book Big Question – What are you doing? Procedure – what did you do? You might want redo this procedure later, so write enough detail that you can follow it again Results – in a data table, or sketches of observations Reflect – What worked well? What should you improve the next time you do a lab?
