Gizmo Warm-up
Have you ever wondered what is in your food? Scientists
use a variety of tests to determine the nutritional content of
food. You will learn four of those tests with the Identifying
Nutrients Gizmo.
1. Below the Food samples label, drag tube A into the
Food sample holder. Below the Benedict test, click
the Test button. What is done in the Benedict test?

2. The Benedict test is a test for monosaccharides; simple sugars like glucose or fructose
(fruit sugar). In contact with monosaccharides, the Benedict solution turns from blue to
green to orange.
Does Sample A contain monosaccharides? _________
Note: Disaccharides such as sucrose (table sugar) and lactose (milk sugar) are more
complex than monosaccharides. The Benedict test does not detect disaccharides directly.
There are six major
nutrients: Carbohydrates (CHO), Lipids (fats), Proteins, Vitamins, Minerals, Water.
The body uses three main nutrients to function carbohydrate, protein, and fat. These nutrients are digested
into simpler compounds. Carbohydrates are used for energy (glucose). Fats are used for energy
after they are broken into fatty acids.
