Science Fair Project Idea
Scientific Method
Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more

Are you ever annoyed by a poor Wi-Fi signal? What about when you try to send a text message, and it just won't go through because of poor cell service? Have you ever wondered what factors affect the strength of your signal and the speed of the connection? If so, this project is for you! Read more

Engineering Design Process
Can you make water fall up? Or make drops of water hover in mid-air? While you might not be able to make water defy gravity, you can create the illusion that it does using something called the stroboscopic effect. In this project you will make use of the stroboscopic effect to build your own "levitating water" fountain. Read more

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

Scientific Method
Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more

Scientific Method
What keeps a model rocket on course? How can you make sure a model rocket design is stable before you launch it? Find out in this project as you learn about center of mass, center of pressure, and their effect on a rocket's stability. Read more

Scientific Method
Have you ever wondered what causes the tides in Earth's oceans? In this astronomy project, you will discover the answer for yourself! You will investigate how the Sun and Moon control tides in Earth's oceans. Read more

Scientific Method
What keeps you in your seat of a giant loop-de-loop roller coaster? Surprisingly, it is not the seatbelt but the seat! It works because of something called centripetal force and it does much more than make a great roller coaster. It keeps a satellite in orbit and you in your bicycle seat during a turn. How does it work? Read more

Have you ever needed to make a lot of flashcards for a class, but didn’t have the time–or weren’t sure how to make ones that actually help you learn? Maybe you like studying on the go, or you’re trying to squeeze in a quick 10-minute review session between other things. In this project, you will learn how to use ChatGPT (or another AI tool of your choice like Gemini, Copilot, etc.) to generate effective study flashcards quickly and customize them to fit your class and… Read more

Scientific Method
Alka-Seltzer® tablets fizzle furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. In this science project, you can even measure how long and loudly your tablet fizzes using a smartphone equipped with a sensor app. Do you think you can make Alka-Seltzer fizz faster or more loudly by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more
