Explanation
The image displays a screen from an interactive educational module, most likely for a middle or high school science class focusing on biology or chemistry. The user interface elements, such as the score, progress bar, and navigation tabs like “HOME” and “THEORY”, indicate this is part of a larger lesson or virtual lab.
The central task is a data interpretation exercise involving two common biochemical tests used to identify carbohydrates in food samples. The instructions guide the student through a virtual experiment. The first step refers to the Benedict test and the iodine test. The Benedict test is a chemical assay used to detect the presence of reducing sugars, a category that includes simple sugars like glucose. A positive result is indicated by a color change from the initial blue of the Benedict’s solution to green, yellow, orange, or brick-red upon heating. The intensity of the color change corresponds to the concentration of the sugar.
The second test mentioned is the iodine test, which is used to identify the presence of starch, a type of complex carbohydrate or polysaccharide. In this test, a few drops of iodine solution are added to the sample. If starch is present, the solution turns a deep blue-black color. If no starch is present, the solution remains its original brownish-yellow color.
The student’s objective is to observe the virtual color results of these tests for different food samples and then correctly fill out a table, which is mentioned but not fully visible. They must use checkboxes to indicate whether each sample contains simple sugars, complex sugars, or neither. The exercise is designed to test the student’s understanding of these fundamental food tests and their ability to draw correct conclusions from experimental results.
