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

Protein Fingerprinting

Science Fair Project Idea

Scientific Method

First came the Human Genome Project and now (drum roll please) the Human Proteome Project. Confused? Not surprising as the Human Proteome Project has not received the kind of press that the Human Genome Project did. Nonetheless it is a major, and potentially important, scientific undertaking. Just as the genome is the complete set of an organism's DNA, the proteome is all the proteins expressed in an organism. Why study the proteome? It is because proteins are the work horses of biological… Read more

How Does Robot Behavior Affect Human-Robot Interaction?

Science Fair Project Idea

Scientific Method

Industrial robots, medical robots, service robots, household robots, companion robots—humans and robots are around each other in an ever-increasing number of situations. How robots look and act can have a big impact on how humans react to and feel about them. In this science project, you will program a robot with different behaviors to see how people react. Can you make people feel comfortable alongside the robot? Read more

No Whey! Milk Protein Content Doesn't Change...Or Does It?

Science Fair Project Idea

Scientific Method

Many people you know probably have an opinion about the kind of milk they like to drink—some like it thin and refreshing, others like it thick and rich. Milk can be bought with different fat concentrations, but other than that, it's all the same. Or is it? This science fair project raises a few interesting questions about the other contents in milk. Do all milk products have the same protein concentrations? Do cows produce different types of milk during different stages of lactation?… 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

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

Is It OK to Cheat If Everyone Else Is?

Science Fair Project Idea

Scientific Method

Tests, homework, taxes, speed limits, sports: there's always the possibility of cheating. Design a survey to investigate attitudes about cheating. Are some kinds of cheating worse than others? Are there times when it is OK to cheat, or is cheating always wrong? Do people who admit to cheating have the same attitudes as those who don't? Read more

Investigate Native Plant Evolution with Chloroplast Sequencing

Science Fair Project Idea

Scientific Method

Native plants are important for both ecological and medicinal reasons. However, most native plants are not very well studied. One way to know more about these plants is to understand which other species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a native plant and use this information to determine its evolutionary relationship to other species of plants. If the plant you chose has not been sequenced before, you can… Read more

Tracking Geomagnetic Storms in the Ionosphere

Science Fair Project Idea

Scientific Method

The Sun is the ultimate source of the energy that powers weather systems on Earth. Geomagnetic storms are sun-powered storms in the upper atmosphere, arising from energized particles that are periodically ejected by the Sun. Among other effects, geomagnetic storms can wreak havoc with earth-orbiting satellites, and disrupt satellite communications. The global positioning system (GPS) is a network of 24 earth-orbiting satellites that constantly sends radio signals through the earth's… 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
