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 Imagine if instead of spooning up a bowl of soup, a container of yogurt, or a cup of pudding you could just pick up and pop in your mouth a round, mess-free, ball-like blob of one of those. It might feel like snacking rather than eating a meal! In this food science project you can try exactly that. The simple step-by-step directions will lead you through trying a fun cooking technique called reverse spherification to turn yogurt into semi-solid balls, which are called "raviolis." How do you… Read more

thumbnail While looking at a package of dry yeast it is hard to believe that the package has organisms in it that are alive. But add the right ingredients and presto, the mixture becomes a bubbly, oozing, mess of life! What are the right ingredients? What does that yeast need to become active? Do this science project and figure it out for yourself! Read more

Science Fair Project Idea
thumbnail What do sand and cereal have in common? They are both granular materials, which means they are made up of solid particles, but they can actually flow like liquid. When two granular materials with very different-sized particles are mixed, you can actually separate each type by putting them in a rotating device called a tumbler. In this science project, you will examine how common household granular materials behave when mixed together in a moving container Read more

Science Fair Project Idea
thumbnail Have you ever wondered how antibiotics and other medicines are able to stop dangerous infections? How do such medications kill microorganisms without in general harming the person the microorganisms are infecting? Because many different types of microorganisms can infect us, we have had to develop an amazing number of ways to deal with these harmful microbes. Fungal infections can be particularly dangerous, but we have developed many different antifungal medications that can usually deal with… Read more

Science Fair Project Idea
thumbnail Where do you get your best ideas? At school with your friends? When you are out for a bike ride? Over 2,200 years ago, a scientist named Archimedes got one of his best ideas when he sat down in his bath. Eureka! He went running through the streets without even bothering with his clothes. What was he so excited about? He had discovered that when objects, like his body, are placed in water, water is pushed out of the way. Have you noticed that, too? The weight of the water that is pushed out of… Read more

Science Fair Project Idea
thumbnail Comets—big lumps of rock, ice, and frozen gases that orbit the Sun—are among the most amazing heavenly objects seen in the night sky. The glowing tail behind the comet's nucleus inspires wonder. But did you know that a comet's tail is evidence that it's melting? As a comet passes by the Sun on its orbital path, it starts to melt. But do bigger comets melt faster than smaller comets? In this astronomy science project, you will investigate how the size of the comet affects the… Read more
