When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you are hoping it is not gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope it is gone for good! It might be nice to know for sure either way. Try this project to find out. Read more

Vibrobots are fun little robots built from common household supplies, that are powered by vibrating motors. In this engineering project, you will design and built your own vibrobot. Would you rather have a robot that skitters quickly across a table or one that spins wildly in circles? How about a sumo-wrestling bot that can push others out of its way? The choice is up to you!

This project is inspired by the Banaue Rice Terraces, 2,000 year old structures carved into mountainsides in the Philippines. See if you can recreate the water flow of this ancient marvel, often called the Eighth Wonder of the World, using just household materials! The 2017 Fluor Engineering Challenge is over but you can still try out the project and compare your design to the high scores, or use the idea for a science fair or classroom activity. Read more

Did you know that the most likely time to be struck and killed by a car in the United States is at dusk, dawn, or at night? In 2014, 3 out of every 4 pedestrian fatalities happened in these types of poor light conditions. Is there something you could do to decrease the chances you, your friends, and your family members are safer when walking or biking at night? Do you think the types of clothes that you wear could make a difference in how visible you are to drivers? Explore the science of… Read more

Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called… Read more

Are you convinced that virtual reality (VR) will soon become mainstream and improve our lives in unpredicted ways? Or maybe you believe it is a big hype doomed to fade and disappear. In this science project, you will use one aspect of VR—the headset—and investigate if it could convey reality better than traditional pictures or 360° images. You will go out and measure how people perceive pictures and images you took. Will people embrace the VR headset and what it can do or prefer… Read more

Science Fair Project Idea
Your drinking water probably started out brown and muddy. Are you surprised? Maybe you were picturing it flowing from a clean mountain spring instead? All over the world, including in 68% of American homes, people get their drinking water from rivers, lakes, and other surface waters. This water is filled with dirt, debris, and other contaminants as it travels hundreds of miles. So, how does your drinking water go from brown and muddy to crystal clear? Often, flocculants—substances that… Read more
