Effect of Temperature on Elasticity of Rubber Bands

Science Fair Project Idea

Scientific Method

How much force can a rubber band withstand before breaking? Do rubber bands that stretch longer take more or less force to break? How does the elasticity of a rubber band change with temperature? Use a spring scale to measure the applied force, and a meter stick or ruler to measure the change in length. Recording with a video camera (or possibly two) can help you to capture the values at the moment before the rubber band breaks. You can change the temperature of the rubber bands using… Read more

Construct a Carnival Buzzer Game with a Raspberry Pi

Science Fair Project Idea

Scientific Method

Have you ever played a game that tested the steadiness of your hands? Operation® is a popular board game that requires you to perform "surgery" without bumping a tool against the edges of the game. There are also popular amusement park or carnival games where you try to move a metal loop along a wavy metal wire without letting the two touch. You can build your own version of these games using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks… Read more

How Secure Are Your Security Questions?

Science Fair Project Idea

Scientific Method

Many websites ask you to answer "security questions," like "What is your mother's maiden name?," to recover your account if you ever forget your password or login ID. However, sometimes the answers to those questions are easy to find online. Does this pose a risk to the security of important accounts like email and online banking? Are people even aware that this information about them is available online? In this project, you will investigate how secure people think security questions are, and… Read more

How Quickly Does a Tennis Ball Lose Its Bounce?

Science Fair Project Idea

Scientific Method

The rebound rating is the ratio of the height the ball bounces to, divided by the height the ball was dropped from. Use the rebound rating to measure the bounciness of new tennis balls vs. balls that have been used for 10, 20, 50, and 100 games. Another idea to explore: does it matter what type of court the ball is used on? (See: Goodstein, 1999, 63-64.) Read more

Can Water Plants Be Used to Determine Water Quality?

Science Fair Project Idea

Scientific Method

Some plants grow only in water-logged environments. These plants are usually native to wetlands and are important for the sustainability of aquatic ecosystems. Wetland ecosystems are very fragile and susceptible to the toxic dumping of sewage and fertilizer run-off from neighboring farm land. One very common aquatic plant called duckweed inhabits many wetland marshes. Duckweed grows by asexual reproduction and floats at the surface of the water with tiny roots extending into the water below.… Read more

Now You See It, Now You Don't: Investigating Inattentional Blindness

Science Fair Project Idea

Scientific Method

Have you ever taken notes from the chalkboard during class and not noticed what was going on around you? Or have you ever been so focused on a task that you haven't seen other people around you? In both of these cases, you were paying attention, but you were seeing without seeing! This is called inattentional blindness and it's the topic that you will investigate in this human behavior science fair project. If you are interested in how the human brains perceives information, then this might… Read more

The Sweet Beginnings of Caramelization

Science Fair Project Idea

Scientific Method

Caramelization is the name of the cooking process that occurs as sugar is heated and the molecules begin to break apart. But what happens to the sugar as it breaks apart? And what do the physical changes mean for the flavor of the sugar? Using the Internet or cookbooks, read up on the chemistry of caramelization, then head to the kitchen with an adult to caramelize your own batch of sugar. With an adult's help, dissolve 1 1/3 cups of sugar in 2/3 cup of water. Heat the mixture in a pan over… Read more

Do People Use Different Passwords for Different Accounts?

Science Fair Project Idea

Scientific Method

Do you ever use a password to log in to a computer, email account, or website? Do you use the same password for each one? Even if your password is very long or hard to guess, using the same password for many accounts can still be risky. If someone manages to find out your password (for example, via a phishing attack, or if you write your passwords down and someone finds the piece of paper), they could easily access many of your accounts. However, memorizing lots of different passwords can be… Read more

Antioxidants

Science Fair Project Idea

Scientific Method

Antioxidants have become very popular in the news lately for their potential health and anti-aging properties. Antioxidants work by preventing oxidation reactions that produce free-radicals which can cause harm to the body. Try testing different vitamins for antioxidant activity. How do vitamins A, B, C, and E compare? Do some vitamins have more antioxidant activity than others? What are some other sources of antioxidants? Try testing extracts from proposed sources of antioxidants like coffee,… Read more

What Material Makes the Most Resonant Soundboard?

Science Fair Project Idea

Scientific Method

If you like music and musical instruments, here is a project that might resonate with you! This is a fun experiment to investigate materials that could be used to build acoustic musical instruments. You can use a music box mechanism and a sound level meter to see which materials make the best soundboards. Read more
