Science Fair Project Idea

Scientific Method

What do pizza, milk shakes, and ice cream sundaes have in common, besides being delicious and loaded with calories? You might be surprised to learn that these foods, because they contain dairy products, cannot be eaten by the majority of people around the world. Dairy products contain the sugar molecule lactose, and the majority of people on the planet slowly begin to lose the ability to digest lactose after the age of 2. In this human biology and health science fair project, you will… Read more

Do You Hear What You See?

Science Fair Project Idea

Scientific Method

Have you ever wondered how virtual reality works? With virtual reality, people feel like they are in one place while knowing they are somewhere else. In this project, you will show the same phenomenon on a smaller scale. You will use the McGurk effect to show how you can hear one sound, while knowing a different sound is physically there. First, you will produce such an experience using audio and video, and then measure the strength of the phenomenon. Read more

How Do Cats Respond to Bird Sound Recordings?

Science Fair Project Idea

Scientific Method

Cats are great house pets, but as every cat observer knows, they are also instinctive hunters. This experiment provides an interesting way to learn about cat behavior. You'll play bird call recordings for pet cats, and watch to see if the cat pays attention to the sound (by turning towards it) or ignores it. Will a pet cat distinguish between the calls of local birds vs. non-local birds? Read more

Which Bait Works Best for a Homemade Fly Trap?

Science Fair Project Idea

Scientific Method

Do you really catch more flies with honey than with vinegar? Do an experiment to find out! Watch the video above to learn how to make a simple homemade fly trap using a plastic bottle. Then, experiment to discover which bait attracts the most flies. You can try a variety of liquids, and you can also use solid bait like rotting food or meat, but you will need to add some water so the flies drown. A drop of soap can help break the surface tension of the water, making it easier for the flies to… Read more

What A Drag!

Science Fair Project Idea

Scientific Method

What makes some objects more streamlined than others? Find out which ordinary objects around your house are made to move smoothly through the water in this easy science fair project. Which objects will produce the most drag when pulled through the water? Read more

Power Play: How Does Animation Timing Affect Your Perception of Game Action?

Science Fair Project Idea

Scientific Method

"Pow!" Wow, what an awesome punch that character has! Ever wondered what goes into making a punch look good in a video game? Or any other character motion sequence, for that matter? Try this science fair project for a firsthand look at how art and timing can create memorable game action. Read more

Happy or Sad? Use Artificial Intelligence to Classify Faces

Science Fair Project Idea

Engineering Design Process

Do you think artificial intelligence (AI) is too complex to use? Think again! In this project, you will use AI to teach a web-based tool to classify happy and sad faces, or other objects, poses, or sounds. This experiment requires no coding skills; instead, you will need curiosity, creativity, and a critical eye. Why not give it a try yourself? Read more

Design Your Own Virtual Reality Headset

Science Fair Project Idea

Engineering Design Process

Virtual reality (VR) headsets are becoming increasingly popular with consumers for things like viewing 3D pictures and videos, or for playing video games. However, dedicated gaming headsets like the Oculus Rift® and PlayStation® VR can cost hundreds of dollars. Some headsets, like Google Cardboard™, which is literally made out of folded corrugated cardboard (Figure 1), are much cheaper because they can use any smartphone as the screen. Figure 1. A… Read more

Wearable Limp Detection Device

Science Fair Project Idea

Engineering Design Process

Have you (or anyone you know) ever sprained an ankle or broken a leg? It might have taken some practice to walk again after recovering from an injury. Some people might even need to work with a physical therapist. In this project you will program a wearable device to recognize when someone is limping instead of walking normally. Read more

Ocean Currents and Weather

Science Fair Project Idea

Scientific Method

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… Read more
