How Many Numbers Can You Remember?
Science Fair Project Idea
Scientific Method
Are you good at remembering addresses and phone numbers? How many numbers do you think you can remember? Try this experiment to test your digit span, the maximum number of digits that you can remember. Read more
Human Perception of the Anomalous Mirror Symmetry Illusion
Science Fair Project Idea
Scientific Method
The Science Buddies project Design Your Own 3D Printed Optical Illusion shows you how to make your own 3D printed "anomalous mirror symmetry" illusions (Figure 1). The illusions are based on the work of Dr. Kokichi Sugihara. You can read his original paper about the illusions in the Bibliography. Figure 1. Two versions of the "impossible arrow" shape that appears to point to the right while its reflection in the mirror appears to point to the left. Which version of… Read more
Make a Mood Tracker
Science Fair Project Idea
Engineering Design Process
How do you feel right now? Do you remember how you felt a few hours ago? How about yesterday or last Wednesday? What if you could track your emotions throughout the day and use this information to help improve your mood and well-being? In this science project, you will program a simple, pocket-sized device that you can carry around with you to log your feelings whenever you want or on a specific schedule.  Read more
Memory Mnemonics
Science Fair Project Idea
Scientific Method
Have you ever had to remember a long list of planets or the state capitals? These kinds of lists are full of interesting facts, but they can be hard to remember, especially for tests. What could you do to remember the list better? In this human behavior science fair project, you will learn about a memory technique called mnemonics (pronounced nuh-MAH-nicks) and investigate whether using mnemonics can help you and your friends remember lists of words.

Multitasking: Brain Drain or Boost in Efficiency?
Science Fair Project Idea
Scientific Method
Think it's a good idea to plug into iTunes, surf the Web, or watch TV while doing homework or trying to read? Lots of people do it and claim that jumping from one activity to another keeps their attention level up and even gives their brain some time to "relax" between the more challenging tasks. Just how efficient is multitasking? In this project, you'll find out after testing the ability of volunteers to successfully do two or more things at once. Read more
Racial and Gender Bias in AI-Generated Images
Science Fair Project Idea
Scientific Method
If someone asks you to draw a picture of a doctor, lawyer, or engineer, what first pops into your mind? The race and gender of the person you imagine might be shaped by your personal life experiences, such as whether you have family members in those professions, or what representations of them you have seen on TV or online. What do you think will happen if you ask an artificial intelligence (AI) program to generate the picture instead? Will pictures generated by AI reflect the true real-world… Read more
Warped Words and the Stroop Effect
Science Fair Project Idea
Scientific Method
The Stroop effect describes an experiment about the time it takes to name the color of printed words. When you try to name the color in which color words are printed, it takes longer when the color word differs from the ink color than when the color word is the same as the ink color. This project is an interesting variation: what happens if you 'warp' the words into a curved shape that is harder to recognize as a word? Will the Stroop effect still happen? How 'warped' do the words have to be in… Read more
Candy Confusion: Can Small Children Mistake Medicine for Candy?
Science Fair Project Idea
Scientific Method
Many medicines come in bottles with special child-proof caps so that small children can't accidentally open the bottle and eat the pills. To a small child who can't read the label, the pills might look just like candy. What cues do we use to tell the difference between medicine and candy? At what age can we tell them apart? This project can show you how to find out. Read more
Do People Use Different Passwords for Different Accounts?
Science Fair Project Idea
Scientific Method
Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be… Read more
Fear Factor: Using Pulse Rate to Measure Emotion
Science Fair Project Idea
Scientific Method
Oh, were you ever scared! Your heart pounded, your breath rate shot up, your palms got cold and clammy. Fear does that to us. Here's a science project based on roller coaster rides to see if heart rate is an accurate measurement of fear. Are you brave enough to take on this frightfully fun project? Read more
