Science Fair Project Idea

Scientific Method

When pesticides are applied to protect crops, run-off of potentially harmful pesticides is a major problem. Can water plants such as hardstem bulrush, common cattail, parrotfeather and smooth scouring rush promote pesticide breakdown? If so, diversion of irrigation run-off into plant-filled ponds could help reduce pesticide pollution. Mix malathion at 12.5% of the recommended application strength (to simulate dilution by rain or irrigation water). Use 5-gallon buckets for testing various… Read more

Do Stress Management Techniques Work for Different Types of Stressors?

Science Fair Project Idea

Scientific Method

Have you ever noticed that your heart beats faster when you’re nervous before a big event? How and when does your heart rate slow down back to normal? In this science experiment, you will see if you can use different stress reduction techniques (meditation, yoga, breathing techniques) to determine which type works best for different kinds and intensities of stressors (physical or mental). You can also record other physiological measures, such as blood oxygen and blood pressure, to see how… Read more

Do String Players Have Longer Left Fingers?

Science Fair Project Idea

Scientific Method

Physical activity is needed for maintaining normal bone strength and mass. Can physical stress on finger bones during development lead to an increase in finger length? Check out this project to see how violin players are an example of a "natural experiment" that you can use to answer this question. Read more

Do Your Storm Drains Keep the Ocean Trash Free?

Science Fair Project Idea

Scientific Method

Did you know that there is plastic in the ocean? It probably isn't too hard to imagine that some of the plastic that litters roadways, sidewalks, and parks finds its way into the ocean. So, how much do you think is in there? Hundreds of pounds of plastic? How about thousands of pounds? No one knows for sure, but estimates, based on scientific surveys, suggest the amount is in the range of millions of pounds of plastic! Of course, the ocean is big, over 300 million square kilometers, so… Read more

Does Birth Order Affect Grade Point Average?

Science Fair Project Idea

Scientific Method

Is there a correlation between birth order and grade point average? Design a survey study to find out. How many completed surveys do you need for a representative sample of your school? If you limit your survey to one school, would you expect it to be representative of a larger population (such as your county or state?) How do you control for potential effects of parental age at birth? (In other words, younger siblings will have a higher probability of being born to older parents. If there… Read more

Does Body Size Matter?

Science Fair Project Idea

Scientific Method

Animals come in all shapes and sizes, even humans. You can look up different statistics about different kinds of animals using the Internet: average body size, brain size, life expectancy and generation time are some examples. Is there a correlation between body size and life span? Is there a correlation between body size and brain size? Is there a correlation between body size and generation time? Is there a correlation between body size and the size of your footprint? (Comparative Mammalian… Read more

Does Chemical Lightening Affect the Structure of Human Hair?

Science Fair Project Idea

Scientific Method

Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Can a human hair hygrometer also detect changes in hair structure caused by chemical lightening? This project shows you how to find out. Read more

Does Gender Affect Color Preference?

Science Fair Project Idea

Scientific Method

If you compare products made primarily for boys with products made primarily girls, you will probably notice differences in colors for the two groups. Why do you think this is? Is it the marketplace responding to gender-based color preferences? Do you think it's the other way around, and the products create gender-based color preferences? Design a survey study to find out if gender actually make a difference in color preferences. Here are some questions you might want to consider when… Read more

Don't Stand So Close To Me! An Investigation into Personal Space

Science Fair Project Idea

Scientific Method

How do you feel when a friend comes too close to you? How far away or close do you think is necessary to have a conversation with someone? The answers to these questions are dependent upon the size of your personal space. Some people like to be within a foot of each other when having a conversation and others feel that being 3 feet apart is still just a little too close for comfort. Personal space is defined as the protective area surrounding a person's body (not necessarily spherical in… Read more

Earth Surface Dynamics

Science Fair Project Idea

Scientific Method

Think about mountain ranges, canyons, sand dunes, or any other interesting geological feature you may live near enough to visit. The surface of the Earth is always changing due to a balance of forces both above and below the surface. Below-surface forces cause the Earth's crust to be faulted, folded, tilted, and lifted. Above-surface forces are primarily due to the natural processes of weathering and erosion. Can you show the effects of these forces using scale models, demonstrations,… Read more
