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

Which Metal Is the Most Resistant to Corrosion?

Science Fair Project Idea

Scientific Method

Here's a practical engineering challenge: you need to build an enclosure for your dogs, using material that they can't chew through. It's going to be a lot of work to build, so you want to do it right. What material should you choose for the fencing? This project uses the scientific method to evaluate materials. Read more

Cookies: Can You Blame the Burnt Ones On the Cookie Sheet?

Science Fair Project Idea

Scientific Method

Have you ever bitten into a beautiful golden-brown cookie only to realize in dismay that the bottom is burned and black? What causes that uneven baking? Can it be prevented? You can discover the answer by conducting a science fair project to determine whether different types of cookie sheets result in noticeably different cookies. First you'll need to do some background research to figure out what kinds of baking sheets you can buy. For example, there are aluminum, steel, insulated, and… Read more

Rooftop Gardens: Are They a Cool Idea?

Science Fair Project Idea

Scientific Method

Would you like some sky vegetables for dinner? How about some fresh-cut roof flowers to put in vases in your house? Around the world, rooftops are being transformed into living green expanses. Besides beauty, rooftop gardens have a number of advantages, including growing food and taking carbon dioxide out of the air while releasing breathable oxygen. But can rooftop gardens also keep your house cooler and lower your energy bill? Try this science fair project to find out. Read more

Take a Hike: Train Your Robot Dog to Walk with a Virtual Leash

Science Fair Project Idea

Scientific Method

Have you ever walked a dog on a leash? Depending on how well-behaved the dog is, it can be very easy or very difficult. It would be great if you could tell your dog exactly how to behave, right? With that in mind, in this project you will build a robotic dog using a LEGO® Mindstorms® kit that you can teach to "walk" using the beam from a flashlight as a virtual leash. But your robot dog will not know how to walk on a leash on its own — you will have to "train" it, just as you… Read more

Altitude and Weather

Science Fair Project Idea

Scientific Method

As you move up or down in altitude or elevation, the temperature and pressure will change. This is particularly striking if you live near a mountain range. During the summer, at low altitudes you may have temperatures in the 80's or 90's and still be able to see snow on mountain peaks at high altitude. You can test the effect of altitude by comparing temperature data from weather stations at high and low altitudes. You can test the effect of elevation by making your own weather balloon and… Read more

Explore Perceptrons: A Simple Type of Neural Network

Science Fair Project Idea

Engineering Design Process

Have the phrases "machine learning" or "neural network" caught your interest, but you are not really sure how to use them in a science project? This project is a great place to start for beginners. You will learn about a very simple type of neural network—a computer program modeled after the human brain—called a perceptron. The perceptron can make a simple yes/no decision based on several inputs. You can "train" your perceptron to improve its decision-making abilities. Try it and… Read more

Get Crafty — Create Your Own Durable Paper Doll

Science Fair Project Idea

Scientific Method

Through the ages, creative minds have made an amazing variety of paper toys, many of them delicate, beautiful, and inspiring. All too often, though, they do not withstand very well the wear and tear of play. This science project is your chance to fix that. You will make paper dolls with movable parts and study how the choice of materials influence the strength of the toy. Beginning with a strong design, you will finish by making a durable paper doll (or toy) with moving parts. Read more

Making It Shipshape: Hull Design and Hydrodynamics

Science Fair Project Idea

Scientific Method

Sailboats, tugboats, barges, ocean liners, submarines are all different boats with different shapes. How does the shape of a boat's hull affect how easily it moves through the water? This project shows you how you can investigate this question using a homemade water trough and model boat hulls. Read more
