Manipulating Sound Files

Science Fair Project Idea

Scientific Method

Learn how to edit sound files so that you can manipulate the recorded sound mathematically. You can either find specialized audio editing software or do background research to teach yourself about sound file structure so that you can write your own simple program to manipulate sound files. Try arithmetic operations on the sound values (e.g., adding or subtracting a constant, multiplying or dividing by a constant). How do these operations alter the sound? Try other mathematical operations:… Read more

Program to Check (or Solve) Sudoku Puzzles

Science Fair Project Idea

Engineering Design Process

Sudoku is an extremely popular puzzle game. You start with a 9x9 grid of squares, which contains three smaller 3x3 subgrids. Some of the squares are filled in with numbers 1 through 9. Your goal is to fill in the remaining blank squares such that each column, each row, and each 3x3 subgrid contains the numbers 1-9. No number can appear more than once in any column, row, or subgrid. For a given starting puzzle, can you write a program to check if a Sudoku solution is valid using a programming… Read more

Programming NANORGs in a Virtual World

Science Fair Project Idea

Scientific Method

Imagine yourself as a software engineer, a decade and a half from now. You are called upon to help solve the world energy crisis by programming nano-organisms (NANORGs) to extract energy from industrial sludge. Your program must be small enough to fit in the NANORGs' tiny processors, yet at the same time meet several challenges. First and foremost, your NANORGs need to navigate on their own, extract energy from the sludge, and find collection points to deliver the harvested energy. Second,… Read more

Sound Frequency Analysis.

Science Fair Project Idea

Scientific Method

Here's an interesting project idea with a variation that combines computer science, physics and music. You'll need a piano in a quiet room, a microphone and a computer with digital sound recording and analysis software. The project shows you how you can make a piano string start vibrating without hitting its key. You can record the sounds on the computer, and use sound analysis software to measure the frequencies of the induced vibrations. For more details see: How to Make a Piano Sing. Be… Read more

What's the Fastest Way to Sort a List?

Science Fair Project Idea

Scientific Method

Imagine that you have a list of names of all the people in your class. Someone asks you to put them in alphabetical order. How would you go about doing it? Would you first go through the entire list and look for all the "A" names? Then go through it again and look for all the "B" names, and so on? Do you think going through the list over and over again for each letter would be inefficient? What if you had hundreds, thousands, or even millions of names? How would you ever alphabetize them… Read more

Write a Program to Analyze Text and Guess the Author

Science Fair Project Idea

Engineering Design Process

Do you think you could figure out if two different anonymous messages were written by the same person? What about telling the difference between text written by a human and something written by artificial intelligence (AI)? How about identifying the author of a historical text? Each individual author may have their own personal style, and analyzing text mathematically can help you identify that style. Can you write a computer program that takes a passage of text as input, and calculates the… Read more
