Did you ever think of lying as an interesting social skill? Lying is actually tied to empathy, the ability to see things from another person’s perspective. Most humans begin to develop these skills around the age of three, when they begin to understand that what they know about the world might be different from what other people know about the world. Telling lies might be a skill, but lies can be bothersome. Sometimes, you really like to know how to tell a truth from a lie. Will the… Read more

Planet Hunters TESS

Science Fair Project Idea

Scientific Method

The Transiting Exoplanet Survey Satellite (TESS) is a space telescope for NASA's Explorers program, designed to search for exoplanets using the transit method in an area 400 times larger than that covered by the Kepler mission. It was launched on April 18, 2018 atop a Falcon 9 rocket. During its two-year primary mission, it was expected to find more than 20,000 transiting exoplanets, compared to about 3,800 exoplanets known when it launched. The first light image from TESS was taken on August… Read more

Plants Are On The Move! A Study of Gravitropism

Science Fair Project Idea

Scientific Method

As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move! This experiment will investigate the stimulus/response relationship in plants and prove that plants can move up and down in response to gravity. Read more

Play-Doh Math

Science Fair Project Idea

Scientific Method

Have you ever had fun making different figures or colorful creations using some Play-Doh? You can squish and stretch a single piece of Play-Doh® to make all sorts of shapes. How does changing the shape of a piece of Play-Doh affect its volume? In this science project, you will find out by testing how changing a piece of dough's shape affects its dimensions (length, width, and height), and how these changes are related to the dough's volume.

Playing Music

Science Fair Project Idea

Scientific Method

Music has many mathematical elements in it: rhythm, pitch, scale, frequency, interval, and ratio. There are many ways to turn these elements into a science fair project. You can investigate how the scale is based upon a special type of number sequence called a Harmonic Series. Another scale used by Bach, called the "Well-Tempered-Scale" or the "Equal-Tempered-Scale", is based upon a series. How are these mathematical series and ratios related to notes, chords, intervals, and octaves? You can… Read more

Playing the Angles: The Physics of Balls Bouncing Off of Surfaces

Science Fair Project Idea

Scientific Method

Think of hitting a baseball, heading a soccer ball into the net, or hitting a tennis ball with a racquet. Where the ball goes depends on...what? You can set up a simple model to start your investigation. You'll need a marble, a flat piece of wood, a flat piece of cardboard, a pencil, a ruler, a protractor, and a level surface. Lay down the cardboard down on a level surface and set up the flat piece of wood at one edge. The wood will act like a wall, and you're going to roll the marble at… Read more

Polar Puzzle: Will Ice Melting at the North or South Poles Cause Sea Levels to Rise?

Science Fair Project Idea

Scientific Method

If you leave an ice cube out on the kitchen counter and come back to check on it in awhile, what do you find? A puddle! The same thing happens to ice in nature—if the temperature gets warm enough, it melts. In this ocean science project, you will find out what happens to sea levels if the ice at the North Pole melts, or if the ice at the South Pole melts. It is an important question for the millions of people who enjoy living along the coasts of the world. Read more

Pop Goes the Geyser!

Science Fair Project Idea

Scientific Method

Our home, Earth, is a living planet. Earthquakes and volcanic eruptions are proof that the geological forces that shaped our planet and created the land masses are ongoing. An amazing example of geologic activity that is less damaging is a geyser. In this geology science fair project, you will build a model geyser and determine how depth of the source affects how the water is ejected. By the end of this project, you will know a lot more about geysers and understand that a geyser is much more… Read more
