A Juicy Project: Extracting Apple Juice with Pectinase

Science Fair Project Idea

Scientific Method

Do you know why enzymes are oftentimes called the workhorses of biochemistry? It's because they can speed up a wide variety of chemical reactions, and chemists and biologists use enzymes to do all kinds of jobs. In this project, pectinase, an enzyme frequently used in the food industry, will be used to extract juice from apples. Read more

Absorption of Radiant Energy by Different Colors

Science Fair Project Idea

Scientific Method

Everyone has experienced the warmth provided by a shaft of sunlight through a window. In this physics science fair project, you will determine how the color of an object affects the amount of radiant energy that is absorbed. You will then use the Stefan-Boltzmann equation to determine the amount of energy that is absorbed and re-emitted by the different colors. Read more

Have you ever wondered how visual illusions are made? When we see special effects in movies, or a magic show, we often witness illusions that challenge our ability to correctly perceive things. One way in which our eyes play tricks on us is through afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. In this science activity, you will look at afterimages to reveal the secrets of how your eyes see color. Read more

AI Hyperrealism: Do AI Faces Look More Real Than Human Faces?

Science Fair Project Idea

Scientific Method

Artificial intelligence (AI) programs can now generate photorealistic pictures of people who do not exist in the real world. How can you tell if a picture is of a real person or a fake, AI-generated person? What features of the picture do people use to decide whether the face is real or AI-generated? In this project, you will explore these questions as you ask volunteers to look at both real and AI-generated pictures of human faces. Read more

An Experiment on Nitrogen Fertilizers

Science Fair Project Idea

Scientific Method

Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more

Are Composite Faces More Attractive than Real Faces?

Science Fair Project Idea

Scientific Method

Psychologists have long studied why people find certain faces more attractive than others. One interesting method used in this area of research is mixing several faces together to make a composite face. The composite face averages the input faces, so that small, non-symmetric features tend to get lost. In this human behavior science project, you will use an online tool to make composite faces, and determine how they compare to real faces in perceived attractiveness. Read more

Are Your Eyes Playing Tricks on You? Discover the Science Behind Afterimages!

Science Fair Project Idea

Scientific Method

Yogi Berra said "You can observe a lot by just watching." In this human biology science fair project, you will observe how your eyes perceive color by watching afterimages. Afterimages are the images you see after staring at an object for several seconds and then looking away. You will also learn how different cone cells in your retina respond to different colors.

Have you ever seen a mobile? Not a mobile phone, but a hanging art sculpture. You might have had such a mobile in your room when you were little. These mobiles hang from the ceiling and are usually made up of many layers of rods to which lots of differently shaped objects are attached with strings. When you look at the mobile sculpture, you might wonder how it can stay balanced all the time even when it is moving in the air. In this activity, you will make your own mobile sculpture and find out… Read more
