Plastic Deformation: Glass Transition of Some Plastics

Science Fair Project Idea

Scientific Method

Some plastics undergo an unusual transition, from a hard, glassy state to a soft, rubbery state, with increased temperature. For this project, you should do background research on the effects of temperature on different types of plastics. Make sure that you understand the difference between thermosetting and thermoplastic polymers. You should also look for information on the glass transition temperature (Tg) for different plastics. Pure polyvinyl acetate has a Tg of 28 C (about… Read more

Play an Electronic Drumset with a Raspberry Pi

Science Fair Project Idea

Scientific Method

When you were little, did you ever make "music" in your kitchen by banging kitchen utensils on pots and pans? What if you could actually take those kitchen implements now, and play them with different sound effects? In this project, you can convert basic kitchen utensils into your own electronic drum set using a Raspberry Pi. Check out the video to see what this simple, but fun, project looks like. IMPORTANT: The instructions for this project were originally written using Scratch 2 on a… Read more

Playing Games

Science Fair Project Idea

Scientific Method

Almost all of the games we play are based on math in some way or another. Card games, board games, and computer games are designed using statistics, probabilities, and algorithms. Begin by reading about games and game theory. Then you can choose your favorite game and investigate the mathematical principles behind how it works. Can combinatorial game theory help you to win two-player games of perfect knowledge such as go, chess, or checkers? (Weisstein, 2006; Watkins, 2004) In a multi-player… Read more

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

Point, Click, Shoot! Photography with a Pinhole Camera

Science Fair Project Idea

Scientific Method

Do you like to take pictures with a camera? It can be fun to capture important and humorous events in your life on film or on a memory card. Photography is a hobby that people of all ages enjoy because they can creatively express themselves both artistically and scientifically. But when did the science of photography start and have cameras always been such complicated pieces of equipment? In this photography science project, you will experiment with a simple camera called a pinhole camera and… Read more

Polymer Permeability: Which Plastic Wrap Prevents Oxidation Best?

Science Fair Project Idea

Scientific Method

There are currently two different kinds of polymers used for kitchen plastic wrap: low density polyethylene (LDPE) (e.g. Saran or Glad Wrap) and polyvinyl chloride (PVC) (e.g. Reynolds PVC Foodservice Wrap or Boardwalk PVC Food Wrap Film). Which of these materials is less permeable to oxygen? When you slice an apple, the surface of the slice turns brown as the apple is oxidized. Can plastic wrap seal out oxygen and prevent the apple from browning? Which plastic wrap works best? Do… 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

Pop Goes the Metal: How Temperature Affects Snap Time of a Jumping Disc

Science Fair Project Idea

Scientific Method

Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more

Popping an Ollie: How Skateboarders + Physics = A Really Cool Trick

Science Fair Project Idea

Scientific Method

Have you ever seen a skateboarder jump over an obstacle or slide down a railing? It looks like they are defying the laws of physics when they perform these tricks. It looks like it, but that's not the case. Physics describes the motion of objects and it is a skateboarder's best friend! All of these tricks can be explained by physics. In this sports science fair project, you will learn how speed affects "popping an ollie." The ollie is a basic skateboarding trick, and it's the first step to more… Read more
