Background:
Benedicts solution is a chemical solution that changes color in the presence of glucose and other reducing sugars. It is a mixture of sodium or potassium citrate, sodium carbonate, and copper sulfate. It changes from its normal blue color to an orange, red, or yellow. it changes based on the amount of sugar used.

What common foods contain glucose? Materials:
1% Milk
Skim Milk
Diet 7up
7up
Sugar water
Honey
Apple juice
Low Calorie G2
Peach tea
Diet Peach tea low calories
Energy drink
Lemonade flavored Spring Water No Calories
Coconut flavored water with juice no calories
Powerade
Strawberry flavored water no calories
Life water Flavor Fuji Apple pear no calories Procedure:
1. Create a data table with columns labeled Food substances, sugar prediction, observations, and results.
2. Read the food labels and predict the presence of simple sugar in each of the foods. record your prediction.
3. Prepare a hot water bath using a hot plate and 1000 mL beaker.
4. Label all test tubes. obtain a graduated cylinder. Add 10 mL of a different food substance to each test tube. then add 10 mL distilled water. swirl gently to mix.
5. Add 5 mL of Benedict's solution to each tube. use a clean stirring rod to mix the contents. 6. Using test tube holders, warm the test tubes in the hot water bath for 5 minutes. record your observations and results. Data Table:
