Watch Out! That Wild Animal Might Be Rabid!

Science Fair Project Idea

Scientific Method

The word rabid often makes people think of an animal that is extremely violent, crazy, and maybe even foaming at the mouth. But not all animals infected with the rabies disease fit that description. Nevertheless, it is important to avoid animals that have rabies so that you don't get infected. So which wild animals are likely to carry rabies? This science fair project will help you discover the answer! Read more

Iron-Rich Foods: How to Get the Most Out of Them

Science Fair Project Idea

Scientific Method

Did you know that your body needs a certain amount of iron in order to stay healthy? Iron can be found in much of what you consume each day. Almond flour—frequently used in cookies—is just one example of an iron-rich food. However, only a small fraction of the iron in food gets absorbed by the body, partially because the body can only absorb dissolved iron. In this project, you will study whether the acidic environment in your stomach helps dissolve iron. You will use a color-based… Read more

Spare a Watt, Save a Lot

Science Fair Project Idea

Scientific Method

Do you know how much power is used every day in your home? What you might not realize is that making simple changes can save you energy, power, and money. What would you do with extra money? Put it in the bank or get something that you really want? In this science fair project, you will investigate the different uses of electricity in your home and determine if there are simple changes that you can make to save energy and money. Read more

Use Sewable Circuits to Make Cool Costumes and Accessories

Science Fair Project Idea

Engineering Design Process

Do you want to add color-changing lights to your own clothing, costume, or fashion accessory? What about making the lights flash, or adding sensors to make them automatically react to things like temperature or motion? You can do it all with sewable circuits, also called wearable electronics, that let you sew circuit parts directly into fabric. You can make anything from a basic circuit with a few LEDs up to a programmable, Arduino-compatible circuit with multiple sensor inputs and multiple… Read more

Which Is the Better Insulation Material?

Science Fair Project Idea

Scientific Method

You've probably noticed that the price of gasoline has been going up and up lately. Heating oil will probably cost more this winter than last winter, too. Using good insulation material is one way to conserve energy and save money. What insulation materials work better than others? Read more

How Do Plants Change the Buildup of Greenhouse Gases?

Science Fair Project Idea

Scientific Method

Global warming is how scientists describe the gradual warming of our global climate. Scientists think that the trend towards global warming can be attributed to the build up of greenhouse gases in the earth's atmosphere from industrialization. Another problem is deforestation, as we remove plants and trees from the environment to meet a high demand for lumber or by clear cutting fields for farming and urbanization. By removing trees from the earth's environment, are we changing how greenhouse… Read more

Extreme Sounds: Lessons in a Noisy World

Science Fair Project Idea

Scientific Method

Can you hear me now . . . ? Just how loud does a sound have to be for us to hear it? And how loud is too loud for our ears? Learn to measure levels of sound in this project, and discover the amazing auditory range your ears can detect in the noisy world around you. If you have a smartphone handy, you can even do this project without purchasing any additional materials, by using your phone's sound sensor and a sensor app. Read more

Gears-Go-Round!

Science Fair Project Idea

Scientific Method

Music boxes, bicycles, and clocks all have one thing in common: GEARS! You might say that gears make the world turn, since they are in so many mechanical instruments. How do they work and how do you know which gears to use? Find out in this simple experiment. Read more

How Shoe Tread Affects Traction

Science Fair Project Idea

Scientific Method

Have you ever noticed that some shoes grip the ground better than others? The pattern and design of a shoe’s tread can affect how slippery it is on different surfaces. You can test shoes with different tread patterns—like flat, ridged, or patterned—to see which design provides the best grip. By dragging a shoe along a surface with a spring scale at a constant velocity, you can measure how much force is needed for each shoe to slide on various surfaces. With this knowledge, you… Read more

The Paper Plate Hovercraft

Science Fair Project Idea

Scientific Method

You can make a very simple hovercraft with a stiff, disposable plate-a pie plate should work well-and a balloon. Glue a square of cardboard in the center of the bottom of the plate. Make a small hole through the center of both of these layers. Enlarge the hole slightly with a pencil. Push a balloon through the hole so that the opening is on the front side of the plate, and rest of the balloon sticks out from the back. Blow up the balloon, then set the plate down (balloon side up). What… Read more
