Student Exploration: Dehydration Synthesis SE (1)
Student Exploration: Dehydration Synthesis Vocabulary: carbohydrate, chemical formula, dehydration synthesis, disaccharide, glucose, hydrolysis, monosaccharide, polysaccharide, valence Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. If you exercise on a hot day, you need to worry about dehydration. In this context, what do you think dehydration means? - In this context dehydration means the lack of water in your body has led to more water moving out of cells and bodies than the amount of water you drink. Loosing water and becoming dehydrated can led incoordination. One cause of dehydration is heat exposure especially when exercising. 2. Astronauts and backpackers often bring dehydrated food. What do you think dehydrated food is? - Dehydrated food is a way in which astronauts ins pace preserve their food through the process of dehydration. The food has no water or moisture, which makes the food/package lighter and easier for travel. This is a great way for astronauts to have an endless supply of food with no worries about it expiring. Gizmo Warm-up What do rice, potatoes, and sugar have in common? They are all foods rich in carbohydrates. Carbohydrates are an important energy source for your body. The basic building block of most carbohydrate compounds is the molecule glucose. Using the Dehydration Synthesis Gizmo™, you will learn about the structure of a glucose molecule and how glucose molecules can be joined together to make larger carbohydrate molecules. To begin, select the CREATE GLUCOSE tab. 1. Look at the chemical formula for glucose. How many carbon (C), hydrogen (H), and oxygen (O) atoms are found in a molecule of glucose?
