How Vines Find Their Spines: Thigmotropism in Morning Glory Tendrils

Science Fair Project Idea

Scientific Method

We tend to think of plants as immobile, but the tendrils of a vine, such as the morning glory, actually move in response to touch. Tendrils wrap around structures, which give the plant something to grow on. In this science fair project, you will investigate how plant tendrils respond to touch stimuli. Read more

Human-Robot Interaction: Do Looks Matter?

Science Fair Project Idea

Scientific Method

Do you think robots are cute? Funny? Scary? How do robots make you feel? What words would you choose to describe a robot? Find out how people react to robots by building and decorating your own robot in this science project. Read more

Hurricanes and Climate

Science Fair Project Idea

Scientific Method

The past few years have histories of extremely powerful and dangerous storms. Storms have also become more numerous over the last few years. To investigate potential effects of climate on hurricane number and strength, in this project you will study the effects of El Niño on hurricanes. The goal of this project is to study the historic relationship between the El Niño/Southern Oscillation (ENSO) and the number and strength of hurricanes, either in the Atlantic or Pacific Oceans. Since… Read more

I See a Full Moon Rising...and Shrinking...or Do I?

Science Fair Project Idea

Scientific Method

Have you ever noticed how the moon appears bigger at the horizon, just as it is rising over the treetops, than it does later in the evening when it is overhead? Of course, the size of the moon does not change, but our perception of its size changes based on where it is in the sky. In this human biology science fair project, you will investigate Emmert's law, which explains the full moon illusion. You will estimate the size of the perceived increase in the size of the moon at the horizon. Read more

"Grasshopper" by Ryan Wood There are thousands of species of insects in our world, and each are adapted to survive in their habitat. In this activity, students will learn what an insect is and what some of their adaptations are. Then they will put their knowledge into play by "creating" an insect that is adapted to live in their assigned environment. Read more

Investigate the 'Death' of an Orange: How is Rate of Heat Loss Based on the Surrounding Temperature?

Science Fair Project Idea

Scientific Method

Imagine that you are a detective investigating a murder. You have a body that was found in a swimming pool, and someone reported hearing an argument near the pool at 10:00 PM the night before. Your first question might be "Was this person killed around 10:00 PM last night, or at some other time?" One way to answer this question is to measure the internal temperature of the body. The longer ago the killing occurred, the colder the body. But can you assign a specific time of death to a specific… Read more

Is a Deleted File Really Gone?

Science Fair Project Idea

Scientific Method

When you delete a file, by accident or on purpose, is the information really gone? Can you get it back? If you accidentally deleted your five-page report for school, you may be hoping it is not really gone. On the other hand, if you do not want someone to get their hands on the goofy and unflattering pictures you and your best friend took while staying up late the other night, you probably hope the files you deleted are gone for good! Computer experts are often asked about file recovery.… 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

Have you ever found an egg in your refrigerator and wondered if it was cooked? Although eggs drastically change inside their shells when cooked, it is still remarkably difficult to distinguish a cooked egg from a raw one without cracking it open. In this activity, you will find out how physics can help you tell the difference! Read more

Is the Soup Ready? Measure How Much Water is Absorbed by Dried Beans

Science Fair Project Idea

Scientific Method

Dried beans are a major ingredient in dishes served all over the world. In their dried form, they can be stored for years and then "brought back to life" by soaking them in water. In this cooking and food science fair project, you will measure just how much water is absorbed by beans when they rehydrate (soak up water). Can such a little bean really hold that much water?
