How Much Fat is in Your Food?

Science Fair Project Idea

Scientific Method

Have you ever been told to avoid certain foods because they contain too much fat? Almost every food we eat has some amount of fat in it; often in an invisible form so we do not even notice. However, eating healthy does not mean getting rid of all fat in your diet. On the contrary, fat is an essential nutrient for your body! Only consuming too much of certain fat types creates problems. Are you curious about how to determine the fat content of different foods? Gather some chips, chocolate, and… Read more

How Well Do Different Materials Create Static Electricity?

Science Fair Project Idea

Scientific Method

When your parents were kids, they probably wore polyester. Static cling was a major household issue! Now everybody wears cotton, which does not get static cling nearly as much. Why are some materials more susceptible to static cling than others? Investigate how well different materials produce static electricity by making a homemade electroscope and testing it out in this science project. Read more

Landslides: What Causes Rocks to Slide Down a Slope?

Science Fair Project Idea

Scientific Method

Landslides are powerful geological events that happen suddenly, causing fear in people who live in areas with unstable hills, slopes, and cliff sides. Landslides damage the surrounding habitat and can destroy homes in their path. But what causes landslides? Can slides happen on any slope, or do slopes have to have certain characteristics, such as a steep angle and a specific material mass? In this geology science project, you will learn about the different types of landslides and the… Read more

Make an Automatic Braille Display to Help Blind People

Science Fair Project Idea

Engineering Design Process

We take it for granted that computer screens can update the text on their displays. What about braille, the writing system used by blind and visually impaired people? Braille writing usually consists of a series of permanently raised bumps on a surface like a piece of paper or a sign. How can you make these bumps change or "update" to display different text? Find out in this engineering project as you design and build your own refreshable braille display. Read more

Scientific Method

If you love cooking, decorating cakes, or making edible table decorations, this is a project for you! You will compare three different recipes for rice paper and discover the recipe that works best for your application! Read more

Manipulating Magnets to Improve Generator Output

Science Fair Project Idea

Scientific Method

The electricity you use to power everyday devices is generated by electrical generators. These fascinating and powerful machines rely on magnets to function. Though they might seem extremely complicated, once you finish this science project, you will understand how, why, and when they generate electricity. You will build your own generator, make small changes in how exactly the magnets are placed, and test when moving magnets generate electricity. Read more
