Can You Create a Strategic Connect 4 AI Opponent?

Science Fair Project Idea

Engineering Design Process

When you play Connect 4, what strategies do you use to increase your chances of winning? In this project, you will explore how artificial intelligence can make decisions in two-player games such as Connect 4. This project requires little to no coding skill. Instead, you will need patience and an open mind. Why not give it a try yourself? Read more

Can You Walk the Talk? Exploring Distractions and the Timed Up and Go Test

Science Fair Project Idea

Scientific Method

Test your multitasking skills with the Timed Up and Go (TUG) Test! In this challenge, you'll evaluate a person’s functional mobility when they're focused versus when they're distracted. Can your brain handle walking and talking at the same time? Let’s find out! 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

Have you ever wondered why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science activity, you will get to investigate balance using marshmallows, skewers, and… Read more

Classical Music and Cognitive Tasks

Science Fair Project Idea

Scientific Method

Does listening to classical music help or hinder concentration and performance on cognitive tasks? You'll need help from a teacher to design two short, age-appropriate worksheet tests for this experiment. The tests should be of equal difficulty. You'll also need the cooperation of several additional classroom teachers in order to test enough students (at least 50-100, see the Science Buddies resource: How Many Participants Do I Need?). Half the students will take test A while listening to… Read more

Classify Spam Emails with Natural Language Processing

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how your phone or email automatically detects and filters junk messages into spam? This feature helps ensure you focus on the messages that truly matter. In this project, you’ll build your own spam detector using natural language processing (NLP) techniques. Read more

Coffee Buzz: How Does Caffeine Affect the Physiology of Animals?

Science Fair Project Idea

Scientific Method

Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… Read more

Create a Facial Recognition System with Machine Learning

Science Fair Project Idea

Engineering Design Process

Have you ever wondered how your smart devices can recognize and distinguish your face from that of others? In this project, you will explore how to create and modify a facial recognition model using a type of artificial intelligence known as neural networks. This project is designed for beginners and requires little to no coding experience. Ready to give it a shot? Read more

Create and View Your Own 3D Models in Virtual Reality

Science Fair Project Idea

Engineering Design Process

Virtual reality (VR) headsets are becoming increasingly popular. Video game designers use a variety of programs to create the amazing 3D worlds that you see when you turn on your favorite video game, and many of those worlds are now also designed to be compatible with VR headsets. Can you use a computer-aided design (CAD) program or video game engine to design your own virtual world that can be viewed using a VR headset? Table 1 lists several CAD programs and websites that you can use to make… Read more
