Graphical methods of data presentation are a key feature of scientific communication. This project asks the question, "What's the best way to compare the land area of states: a map or a bar graph?" You'll be measuring performance on two different visual discrimination tasks: comparison of areas vs. comparison of position on a common scale. Which method is more accurate? Which method is faster? This project will get you thinking about how to find the best way to communicate scientific…

What do Nolan Ryan, Mark Wohlers, Armando Benitez, and Roger Clemens have in common? These men are all major league baseball pitchers who have pitched baseballs at 100 miles per hour or greater! What does it take to throw a baseball this fast? Does it come down to having the biggest muscles? Can a ball thrown this fast also be accurate? In this sports science fair project, you will learn about the biomechanics of pitching. Investigate how body position and physics interact to produce fast…

What is it that famous photographers do to make their images so pleasing to the eye? Find out if simple rules of geometry can make you a better photographer.
Many things in nature are periodic: the seasons of the year, the phases of the moon, the vibration of a violin string, and the beating of the human heart. In each of these cases, the events occur in repeated cycles, or periods. In this project, you will investigate the periodic motion of a spring, using a mini Slinky®. You can also measure the motion of your spring using a smartphone equipped with a sensor app. Basic physics will then allow you to determine the Hooke's Law spring constant.…
Have you ever taken notes from the chalkboard during class and not noticed what was going on around you? Or have you ever been so focused on a task that you haven't seen other people around you? In both of these cases, you were paying attention, but you were seeing without seeing! This is called inattentional blindness and it's the topic that you will investigate in this human behavior science fair project. If you are interested in how the human brains perceives information, then this might…

What should you NOT forget when going outside on a sunny day? To put sunscreen on! Sunscreen is important because it protects your skin from sunburn. But there are so many sunscreens to choose from: different methods of application (sprays and lotions), different Sun Protection Factors (SPFs), and different ingredients. Which one is best? In this science project, you will test the effectiveness of different sunscreens and find out how water-soluble they are.
Did you know that our brains are split into two parts, right inside our head? One half is the left brain and the other half is the right brain. Some people use one half of the brain more than the other half when they are doing certain activities, like talking or reading. The half that is used is sometimes tied to which hand they prefer to use. If someone likes to use their right hand when doing an activity, like drawing or throwing a ball, do they also prefer to use their right ear, eye, or…
When you think of a machine, you probably think of computers or robots. But what if I told you that machines have been around for centuries? Would you believe me? Try this experiment to see which of these simple machines you use around your house. You might even use some of them everyday!
Have you ever seen a river from far above? It is fascinating how they carve their way through the landscape. But what makes the water in a river flow? Where does a river start and end? And why is it that rivers usually have lots of turns or bends and almost never flow straight? In this science project, you will make river models using aluminum foil and water to explore how water flow inside a river changes based on its shape.
