Testing the Accuracy of Eyewitness Testimony
Science Fair Project Idea
Scientific Method
Think back to the last time you went to the grocery store. How well can you describe the person who was ahead of you in the check-out line? How many details do you remember about the person? How accurate do you think your memory is? Here is a project to investigate the accuracy of people's observations during everyday life. Read more
That's a Real Smile! ...or is it?
Science Fair Project Idea
Scientific Method
If someone is smiling, it means they're happy, right? Well, not always. Sometimes people smile to be polite, or because they want to "appear" happy or friendly for social reasons. How easy is it to spot which smiles are genuine and which are fake? Try this science fair project to find out! Read more
The Brains Behind 'Where's Waldo?'
Science Fair Project Idea
Scientific Method
What makes you notice someone in a crowd? Why do some things stand out, while others melt into the background? In this science project you can investigate the psychology of how things get noticed, by studying how our brains perform a visual search. Have you ever looked and looked desperately for something? It is so frustrating! The classic example is when I lose my keys. You would think that by now (knowing that I am the kind of person who often loses my keys) I would have a huge, bright red… 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
What Conflicting Mental Tasks Reveal About Thinking: The Stroop Effect
Science Fair Project Idea
Scientific Method
Can you pat your head with one hand while you rub your stomach with the other? This science project idea is kind of like doing that, but this project can actually give you some insight into how your mind works. The task is to name colors. It sounds simple enough, but see what happens when color words get in the way. Read more
