Testing for Glucose
Glucose, a sugar used by cells for energy, is not normally present in urine. High glucose
level in urine is a symptom of diabetes, a disease that occurs when the body does not make
or properly use insulin. Insulin is a hormone that helps maintain levels of glucose in the
blood. In a person with diabetes, the kidneys filter excess glucose into the urine.
Design an Experiment
Doctors can test for glucose in urine using glucose test paper, which turns green in the
presence of glucose. Review the list of materials below. Use the materials to design an
experiment that tests for glucose in fake urine. Remember that you will need a control in
your experiment so you can compare results. Write each step of your experiment on the
lines below.
