Science Fair Project Idea
thumbnail If you have ever prepared a cup of coffee or tea with sugar, you have probably seen that the grains of sugar quickly dissolve and completely disappear in hot water. But sugar is not the only type of solid that can readily dissolve in a liquid. In fact, there are some types of rocks that can be dissolved by common liquids. It might be hard to imagine large, hard rocks being eaten away by some ordinary fluids, right? But it actually happens all the time! In this geology science project, you will… Read more

Science Fair Project Idea
thumbnail Everybody knows that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? Here is a project that gives you a peek into the fascinating science of exercise physiology. Read more

Science Fair Project Idea
thumbnail Alka-Seltzer® tablets fizz furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. Can you make Alka-Seltzer fizz faster or slower by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more

thumbnail What is the first thing you do when you wake up on a cold, frosty morning? Snuggle down deeper under the covers? Animals, like puppies and piglets, do not like being cold either, but they do not have hands or blankets to wrap themselves up. So when animals get chilled, they change their behavior and do things like huddle—they curl up close to other animals. In this mammalian biology science fair project, you will see just how much huddling can help reduce heat loss. Read more

Science Fair Project Idea
thumbnail You have probably heard the saying that "water and electricity don't mix." Well, in this chemistry science fair project you will mix them, to create two solutions, one basic and one acidic. The apparatus is very simple, but the chemistry is complex and offers many avenues for exploration. Read more

Did you know that soils can be alkaline, neutral, or acidic? Most plants grow best in soil near neutral pH, but some plants prefer slightly acidic and others slightly alkaline soil. What is the pH of the soil in your garden? What happens to the pH of water that comes in contact with soil? In this science project you will get to find out. 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

thumbnail Have you ever heard that nanoparticles can kill bacteria? You may have even seen some consumer products advertise that they contain antibacterial nanoparticles. A nanometer is one billionth of a meter long. Nanoparticles are usually just a few nanometers in diameter — really, really tiny! So how can something that small kill bacteria which are approximately 700 - 1400 nanometers across? Are they really effective? In this science project you will grow some E. coli bacteria and… Read more
