Others Like “How Sweet It Is! Measuring Glucose in Your Food”

Science Fair Project Idea
thumbnail Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars, glucose and sucrose, in different foods and investigate how sucrose is converted into glucose with the help of an… Read more

thumbnail Do you enjoy eating smoothies packed full of berries and other tasty fruits? Or maybe you like drinking a creamy milkshake with peanut butter, chocolate, and bananas. Often, smoothies and milkshakes are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? Some ingredients in a smoothie can have more than one kind of sugar in them, and our bodies process each kind of sugar differently. In this science project, you will measure the concentration of… Read more

thumbnail What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

thumbnail Cake, cookies, pie, ice cream, hot chocolate, lemonade... Yum! What do all these delicious treats have in common? Sugar. In addition to providing sweetness, sugar adds bulk, flavor, and structure to foods. But is it necessary to add sugar to achieve sweetness? Can the same sweetness be achieved using sugar substitutes like artificial or natural sweeteners? In this project, you will test sugar and sugar substitutes and compare the sweetness of each in relation to sugar. In the end, your day will… Read more

Science Fair Project Idea
thumbnail In this biology science fair project, you will observe how the Physarum polycephalum (P. polycephalum) organism responds to various amounts of glucose. P. polycephalum is easy to grow in a petri dish and responds in complex ways to its environment. Will it grow toward the chemical as it looks for a meal, or will it flee, trying to avoid further contact? Try this science fair project to learn more about chemotaxis in the fascinating Physarum polycephalum. Read more

Science Fair Project Idea
You know there is sugar in non-diet soda, but just how much sugar? Sure, you can look on the ingredients label, but how do food scientists actually measure the amount of sugar in a solution? They use a simple scientific device called a hydrometer. The hydrometer floats in the solution that is being tested, and the higher it floats, the more sugar there is! In this science fair project, you will use a precision hydrometer to measure the amount of sugar in soda. Read more

Science Fair Project Idea
thumbnail Which type of orange juice has the most vitamin C? In this science project, you will learn how to measure the amount of vitamin C in a solution using an iodine titration method. You will compare the amount of vitamin C in three different types of orange juice: homemade, premium not-from-concentrate, and orange juice made from frozen concentrate. Which do you think will have the most vitamin C? Read more

thumbnail Are oranges highest in vitamin C when they are fresh from the tree (or, in a pinch, the grocery shelf)? Does the amount of vitamin C in an orange change over time, after it has been picked? In this science project, you will find answers to these questions by measuring the amount of vitamin C in a solution using an iodine titration method. Read more

Science Fair Project Idea
thumbnail Do you hate shots? Do you complain about paper cuts? Imagine if you had to give yourself shots a couple of times a day, as well as prick your finger, on purpose, even more frequently. Of course, if you have diabetes you do not have to imagine this; it is your reality. People who have diabetes usually need to keep close track of how much sugar is in their blood (called their blood glucose levels)by testing a drop of blood from a finger prick. If there is too much sugar in their blood, some… Read more

Safety Some parts of the circuit can get warm during normal operation. Do not leave the circuit operating when unattended. Be very careful with your wiring to prevent short circuits from happening; short circuits can get very hot and cause plastic parts of the circuit to melt.
Science Fair Project Idea
thumbnail Have you ever been to a buffet and found yourself surrounded by a wide variety of taste sensations? People are generally able to discern five basic tastes: sweet, umami (also known as savory), salty, sour, and bitter. How sensitive is a person's tongue for these basic tastes? Is it easier to detect some flavors at low concentrations compared to others? In this human biology science project, you will find out by exploring your taste thresholds for sweetness, saltiness, and sourness. Get ready to… Read more
