What’s In Your Food?


Harrison Eason testing chemicals for lab.

Food is made up of simple and complex sugars. In Biology, Simple sugars are called monosaccharides and complex sugars are polysaccharides. The type of sugars you eat can determine how much energy you burn, Mrs. Cox’s Biology class sought out to find which foods they eat contain monosacchrides and polysaccharides.

Mrs. Cox’s class used chemical tests to determine the presence of specific molecules in apple juice and  distilled water. The procedure for this lab was to use two different indicators to tests the presence of simple and complex sugars. The class had to use scientific practices to maintain a controlled experiment in order to obtain reliable results.

The class had to give the Benedict test to the apple juice and distilled water. “It[Benedict’s Test] determines whether the substance has monosaccharides or not,” said Harrison Eason (9). The class used test tubes to separate the juice and water then put the Benedicts solution in each test tube. Eason said the way you know if it has simple sugars is, “It will change colors if it does but will stay blue if it doesn’t.”

The testing of simple and complex sugars may seem trivial, but sugars are the building blocks for most of the foods people eat such as fruit, yogurts, rice, cereal, and baked goods.

Eason explains that, “The more carbs you have basically the more substance you have,” and because “Polysaachrides give you more energy,they take longer to break down rather monosaachrides that tend to you make you tired since they are usually the sugars”.

Students in Biology conducting this lab learned a valuable  lesson about nutrition. They learned about how the foods you eat affect the way you feel and how you act and much energy you have during the day.
