Create and Test Your Own Hydrogel Face Mask Recipe!

Science Fair Project Idea

Engineering Design Process

Have you ever tried a beauty face mask? Cosmetic face masks are skin care products that promise rapid hydration of your skin to make it look younger and more radiant. Hydrogel face masks are made of jelly-like materials that are infused with special ingredients to nurture your skin. The ingredients for cosmetic products like face masks are carefully selected by cosmetics chemists. Each product is designed to have the properties that are necessary for its intended purpose. In this science… Read more

How to Balance Anything

Science Fair Project Idea

Scientific Method

Ever wonder why it is harder to keep your balance with a heavy backpack on? Or why it is difficult to make a toddler's sippy cup tip over? Maybe you are the kind of person who wonders about circus balancing acts and would like to learn how to ride a bike on a rope. Or perhaps you want to know how to make your toy car less prone to toppling over when racing through a sharp curve. In this science project you can learn about balance using marshmallows, skewers, and toothpicks. Sticky, yummy… Read more

You Want Fries With That? The Science of Crispy Potatoes

Science Fair Project Idea

Scientific Method

The first bite of a fresh-picked apple, the crunch of morning toast, the deep cut into rich, flaky layers of baklava, the pleasing snap of a chip. Besides being delicious, what do these foods have in common? They're crisp. They have a brittleness that causes them to shatter in your mouth when you first bite into them. It's a sensation that many people enjoy. Making potatoes crispy requires some extra cooking steps, as you'll discover in this food science project, but the results are well worth… Read more

Lift a Load Using Hydraulics

Science Fair Project Idea

Scientific Method

Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more

From Contaminated to Clean: How Filtering Can Clean Water

Science Fair Project Idea

Scientific Method

Living in the industrialized world, like the United States, we are fortunate because we don't have to worry about the quality of our drinking water. Your community has the means to clean and provide water to you. But in many parts of the world, people don't have this luxury. Whether it is due to war or poverty, the lack of clean water leads to many health and social problems. In this environmental engineering science project, you will learn about different methods to filter out impurities in… Read more

Design a Mini Solar Tracker System

Science Fair Project Idea

Engineering Design Process

How can you squeeze as much power as possible out of solar panels if you do not have a lot of space to install them? By tracking the sun! Keeping a solar panel pointed directly at the sun throughout the day can maximize the amount of power it produces. In this project you will design, build, and test your own miniature solar tracking system using a fun block-based programming language - no coding experience required! Read more

From Genes to Genetic Diseases: What Kinds of Mutations Matter?

Science Fair Project Idea

Scientific Method

Our genes are made up of hundreds to millions of building blocks, called DNA nucleotides, and if just a single nucleotide of DNA becomes mutated it might cause a devastating genetic disease. But sometimes a mutation actually does no damage. What kinds of mutations have to occur to cause a genetic disease? In this science project, you will explore online genetic databases to identify how a mutation in a gene can result in a dysfunctional protein, and how other mutations may have no effect at all.

Modeling the Chances of Getting an Autoimmune Disease

Science Fair Project Idea

Scientific Method

Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more

Hit the Slopes: Build Your Own Ski Lift

Science Fair Project Idea

Engineering Design Process

Do you like winter sports like sledding or skiing? Check out this winter-themed engineering project to build your own miniature "ski lift." Use it to transport small objects from one place to another, just like a real ski lift transports skiers from the bottom of a mountain to the top. Read more

What's the Best Exposure Time for Sun Print Paper?

Science Fair Project Idea

Scientific Method

Did you know you can make paintings or drawings using sunlight? You can do it by leaving objects on top of special sun print paper until the light creates an imprint of the objects. How does this process work? How long should you leave the paper in the sun to get the best result? What does any of this have to do with the process of making the microchips that power our phones and computers? Try this project to find out! Check out this page for more science projects related to this process. Read more
