Runoff and Fertilizer Use

Science Fair Project Idea

Scientific Method

Many people routinely use fertilizer for crops, gardens, and lawns. What people don't know is that each time they apply fertilizer, the fertilizer seeps through the soil into the water table. This can eventually lead to the contamination of a local water source, like a stream, pond, lake, bay, or ocean. This is an especially big problem for agricultural practices that frequently use large amounts of fertilizer on fields that are connected by irrigation channels. The run-off of fertilizer… Read more

Use an Arduino™ to Control a Color-Changing Infinity Mirror

Science Fair Project Idea

Scientific Method

This project is a follow-up to the Science Buddies project Explore Optical Illusions: Build an Infinity Mirror, which shows you how to build a basic infinity mirror using light emitting diodes (LEDs) and arts and crafts materials. What if you wanted to build an infinity mirror that could change colors, like the one in Figure 1? Figure 1. A color-changing infinity mirror. You can do this by using special RGB (red, green, and blue) LEDs. Just like the pixels… Read more

How to Make a Guitar Sing

Science Fair Project Idea

Scientific Method

This is a great project for a musician who is interested in the physics of stringed instruments. If you've ever played an acoustic guitar, you may have noticed that picking a single string can make one or more of the other (unpicked) strings vibrate. When this happens, it's called sympathetic vibration. What intervals lead to the strongest sympathetic vibrations? Find out for yourself with this project. Read more

The Case of Mistaken Identity

Science Fair Project Idea

Scientific Method

Mysteries and detective stories have been popular since the time of Sherlock Holmes. The solutions to these fictional cases often involve untangling seemingly contradictory evidence from eyewitnesses. This project studies one procedure used in the real-world process of eyewitness identification of criminal suspects: the lineup. How accurate are eyewitness identifications using various lineup methods? Read more

Crystal Ball Math: Predicting Population Growth with Models

Science Fair Project Idea

Scientific Method

When is an animal considered endangered? When will it become extinct? What happens when a population has reached the limits of its resources? What happens to a population when a habitat changes? These are some of the questions population biologists try to answer. They use population models, created from math equations, to predict what will happen to a population over time. If you want to see how modeling is done and make some predictions of your own, you certainly won't need a crystal… Read more

Hurricanes and Climate

Science Fair Project Idea

Scientific Method

The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. The goal of this project is to study the historic relationship between the El Niño/Southern Oscillation (ENSO) and the number and strength of hurricanes, either in the Atlantic or Pacific Oceans. Since… Read more

Energy Savings with LED Lighting

Science Fair Project Idea

Scientific Method

Global warming, climate change, melting ice caps—these are all big events that have an impact our environment. What can we do to help reduce the impact? We can reduce, reuse, and recycle. What can cities do to help? Cities can eliminate waste by saving energy. Cities around the world are switching from incandescent traffic signals to LED traffic signals to save energy and money. That's because LEDs are more efficient than incandescent lamps, which means that LEDs produce more light… Read more

Preventing SQL Injection Attacks

Science Fair Project Idea

Engineering Design Process

How many websites do you have accounts with that store personal information like your name, email, phone number, or mailing address? If the people running these websites are not careful, hackers could gain unauthorized access to, and even change or delete, your information. They can do this using something called SQL injection, which involves entering malicious code into text fields on a website. In this project you will learn how SQL injection works and figure out how to prevent it. Read more

Mars Terrain Exploration: A Hands-On Coding Investigation

Science Fair Project Idea

Scientific Method

Have you ever wondered what the surface of Mars is really like close up? Are you wondering what the Mars rovers get to see and experience? Some parts of Mars look smooth and sandy, whereas others are covered in rocks and rough terrain. In this project, you’ll step into the role of a planetary scientist and use real Mars rover images and Python code to detect, measure, and compare rocks across different types of Martian terrain. Here you’ll explore how image processing can help… Read more

Lichenometry: An Accessible Method for Dating Recent History (Geological and Manmade)

Science Fair Project Idea

Scientific Method

Have you ever noticed an old stone wall and wondered how long it has been there? If there is lichen growing on the wall, the lichen has most likely been living there since the time the wall was made, so if you could figure out how old the lichen is then you could deduce the age of the wall. Geologies use this method, called lichenometry, and other methods to establish dates and temporal sequences as they seek to construct a history from the available evidence. In this geology science project,… Read more
