Pluck Out & Pick New String Materials for Your Guitar

Science Fair Project Idea

Scientific Method

Walk into any music store and you'll find a dizzying array of string choices for your classical guitar, including rectified nylon, clear nylon, carbon fluoride, bronze wound, phosphor bronze wound, silver-plated copper wire, Polytetra-flouro-ethylene (PTFE), each in a range of tensions from low to high. There is no single best brand or best material. All have their advantages and disadvantages. A set of strings that sounds "sparkling" on one guitar might sound dull on another, primarily because… Read more

Fish Markets and Sustainability

Science Fair Project Idea

Scientific Method

The sustainability of our ocean fisheries is a topic of concern for many, including environmentalists and fishermen who make their living on the bounty of the sea. It is important to use sustainable fishing practices so that our fisheries are not over-fished leading to a decline in productivity. Some states require fish markets to post information about their fish so that consumers can make informed decisions about which fish to buy. They post the type of fish (e.g., Coho Salmon), the source of… Read more

Free Lunch? Can Solar Energy Systems Pay for Themselves with Utility Bill Savings?

Science Fair Project Idea

Scientific Method

If you are interested in exploring how renewable energy can improve the environment, this project could be for you. You'll take on a real-life engineering challenge: deciding whether the benefits of a renewable energy technology are worth the cost to implement it. Some sample questions are suggested, but you can also come up with your own question that matches your specific renewable energy interest. Is there such thing as a free lunch? Read more

Purification Strategies

Science Fair Project Idea

Scientific Method

In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell… Read more

Fractals

Science Fair Project Idea

Scientific Method

A fractal is, "a rough or fragmented geometric shape that can be subdivided in parts, each of which is (at least approximately) a reduced/size copy of the whole" (Mandelbrot, 1982). There are many different fractal patterns, each with unique properties and typically named after the mathematician who discovered it. A fractal increases in complexity as it is generated through repeated sets of numbers called iterations. There are many interesting projects exploring fractal geometry that go beyond… Read more

Solving Logic Problems

Science Fair Project Idea

Scientific Method

You may know Lewis Carroll as the author of Alice in Wonderland, but did you know that in real life he was a mathematician who studied symbolic logic and logical reasoning? How can math help you solve Lewis Carroll's Logic Game? (Bogomolny, 2006) How are algorithms for solving the game Sudoku similar to solving a logic problem? (Hayes, 2006) For the super-advanced mathematical genius, try to evaluate currently available, logic-based computational tools, or design a better one!… Read more

Measuring Height Or Distances with a Camera

Science Fair Project Idea

Scientific Method

If you know or calculate the field of view for your camera, you can use it to measure distances and the height of almost anything. It's all a matter of basic trigonometry. Read more

Lunar Crater Counting

Science Fair Project Idea

Scientific Method

Get good photographs of the Moon showing lots of craters and count how many craters you find in a range of diameter classes. One useful source is the Consolidated Lunar Atlas (Kuiper et al, 2006). Make a histogram that shows the distribution of diameters. Most of these craters were formed during the first billion years of the Moon's formation, but you should confirm that this is true for the the Moon areas you've selected in your photographs by doing background research. Is cratering uniform… Read more

Relationships Between Variables: Using Correlation and Linear Regression

Science Fair Project Idea

Scientific Method

Here's a project that combines sports and math. You'll learn how to use correlation analysis to choose the best team batting statistic for predicting run-scoring ability (Albert, 2003). You'll also learn how to use a spreadsheet to measure correlations between two variables. The project description Which Team Batting Statistic Predicts Run Production Best? provides the details.

Geology and Energy Resources

Science Fair Project Idea

Scientific Method

How is geology important for our energy resources? Coal, oil, and natural gas are formed by geological processes over millions of years. Certain geological formations can indicate a reservoir of coal, oil, or natural gas. Also, geothermal processes can be used as an energy resource. How are these formations identified? How are the resources extracted? You can use the National Geospatial Program to access, view, and download information from geospatial databases containing a broad spectrum… Read more
