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

Science Fair Project Idea
thumbnail Have you ever seen news coverage or other pictures of an oil spill in the ocean and wondered how all of that oil could be cleaned up? Oil spills can devastate wildlife by covering them with oil, and they can damage our precious water resources by contaminating them with oil. Part of the problem of dealing with oil spills is that the oil can be challenging to clean up. In this science project, you will test the absorptivity of different materials (called sorbents) to discover which ones are best… Read more

Science Fair Project Idea
thumbnail The makers of sports drinks spend tens to hundreds of millions of dollars advertising their products each year. Among the benefits often featured in these ads are the beverages' high level of electrolytes, which your body loses as you sweat. In this science project, you will compare the amount of electrolytes in a sports drink with those in orange juice to find out which has more electrolytes to replenish the ones you lose as you work out or play sports. When you are finished, you might even… Read more
