Predicting Future Water Quality with Machine Learning

Science Fair Project Idea

Scientific Method

Understanding the water quality of our rivers, streams, and lakes is critical for maintaining healthy ecosystems and sources of drinking water. Dissolved oxygen is one key water quality measurement that impacts aquatic life. But how can we predict how water quality might change in the future so we can intervene to keep our water healthy? With machine learning! In this project, you will gather water quality data for a location of your choice and use a random forest model to predict future… Read more

How to Control a DIY Mini Drone with an Arduino™

Science Fair Project Idea

Engineering Design Process

Most drones fly with a mix of human input and autonomous control based on feedback from electronic sensors. This allows the drone to fly up and down when the human operator presses a joystick on a controller, but automatically hover at a fixed distance above the ground when the operator lets go of the joystick. In this project, you will explore drone programming with an Arduino. What types of inputs and sensors can you make your drone respond to? What behaviors and responses can you program… Read more

Build a Helping Hand

Science Fair Project Idea

Engineering Design Process

The human body is an impressive piece of machinery, and your hands are no exception. With some training, they can perform delicate and complex tasks like manipulating pens and tools to create art. At the same time, hands have the strength and durability to hold a person's own body weight up on steep rocks. Unfortunately, there is a rapidly growing demand for hand replacements. But fortunately, scientists have studied human anatomy and biology and created human-like hands used as artificial… Read more

Build a Speedy Light-Tracking Robot (BlueBot Project #2)

Science Fair Project Idea

Engineering Design Process

Have you ever seen a cat chase a laser pointer or a flashlight beam? What if you could make a robot do that? In this project, you will build a robot that can automatically drive toward a bright light source. The robot uses a simple electronic circuit to track light, so there is no computer programming required! You can also do three other robotics projects using the same kit of parts, so this is a great way to get started with robotics before moving on to more advanced projects. Read more

Basketball: The Geometry of Banking a Basket

Science Fair Project Idea

Scientific Method

If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more

Make Your Own Wireless Alarm System

Science Fair Project Idea

Engineering Design Process

Have you ever wished you could have an alarm to prevent your little brother or sister from sneaking into your room? How about an alarm to prevent someone from stealing your favorite toy or from taking cookies out of the cookie jar? In this project you will learn how to program your own customized, wireless alarm systems to send you alerts about whatever you want! Read more

Can AI Predict Who Survived the Titanic's Sinking?

Science Fair Project Idea

Scientific Method

Given the right data, AI can be good at making predictions. In this project, you will create a KNN machine learning model that tries to predict whether a passenger on the Titanic survived based on multiple factors such as age, sex, and fare price. This project requires little to no coding skill; instead, you will need an open mind and curiosity to learn. Ready to give it a try? 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

Make a Medical Alert Fall Detector

Science Fair Project Idea

Engineering Design Process

Have you ever wondered what someone would do if they fell, got hurt, and could not get up on their own? What if they were home alone and could not reach a phone to call for help? Or, what if they lost consciousness - is there any way to automatically detect that they fell and needed help? In this project, you will program your own fall detector, a device that can automatically detect when someone has fallen over, then sound an alarm or even send a message to someone else. Devices like these are… Read more

Build a Light-Tracking Bristlebot

Science Fair Project Idea

Scientific Method

Sometimes engineers get ideas to build robots from animals in nature. There are robot dogs, robot snakes, robot birds, robot cheetahs, and even tiny robotic insects! In this science project, you will build a robot insect of your own. The robot will automatically drive toward a light source, mimicking a behavior called phototaxis, seen in some insects. You will build your own robot and then make adjustments so it can reliably drive toward a light. Read more
