Practice

Science Fair Project Idea

Scientific Method

We've all heard that "practice makes perfect," but what is the best way to practice? For example, does "mental practice" do any good? You'll need at least 9 volunteers for this project. Pick a well-defined sports activity, with a measurable outcome, such as shooting basketball free-throws (measure number of shots taken and number of shots made), or balancing on one foot on a slightly raised beam (measure how long you can do it; if it's too easy, try closing your eyes). Test all volunteers… 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

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

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

A Study of Gender Responses to Frustration

Science Fair Project Idea

Scientific Method

Have you ever felt really frustrated? Maybe you were playing a video game and could not easily figure out a particularly challenging puzzle. Or maybe there was something you really wanted but you could not have it for some reason. However it has happened, what do you do when you get frustrated? What about other people — what kind of behaviors have you seen others display when they get frustrated? Do they cry, jump up and down screaming, just give up, or become aggressive? In this human… Read more

Slimey Likes It! Studying Chemotaxis in Physarum Polycephalum

Science Fair Project Idea

Scientific Method

In this biology science fair project, you will observe how the Physarum polycephalum (P. polycephalum) organism responds to various amounts of glucose. P. polycephalum is easy to grow in a petri dish and responds in complex ways to its environment. Will it grow toward the chemical as it looks for a meal, or will it flee, trying to avoid further contact? Try this science fair project to learn more about chemotaxis in the fascinating Physarum polycephalum. Read more

Ocean Currents and Weather

Science Fair Project Idea

Scientific Method

Ocean currents have a huge impact on our weather. If not for the ocean currents, the global climate would be similar to an ice age. Do you live near the coast? Find out which currents are near your coastline. How do they affect your climate? Where do they come from? Do they bring colder or warmer water to your area? Are they seasonal? What do you think your area would be like without them? Every three to seven years there is a weather phenomenon called El Niño, which is caused by… 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

Tick Tock, Tick Tock, Does Your Mouse Know the Time on the Clock?

Science Fair Project Idea

Scientific Method

Mice, rats, and other rodents are typically nocturnal animals; that is, their activity level is highest at night. For this science fair project, you will build a device that records your pet's activity by monitoring movement of its exercise wheel to see how it varies during the day and night. You can also experiment with various ways of changing your pet's cycle of activity; for example, by playing with it during the day when it's normally resting. Read more

Are More Expensive Golf Balls Worth It?

Science Fair Project Idea

Scientific Method

There is a bewildering selection of different golf balls to choose from for playing the game. Some less expensive, some more expensive, all with different claims for the advantages they will bring to your game. This project can help you determine which type of golf ball is right for you. Read more
