How Long Does Trash Last?

Science Fair Project Idea

Scientific Method

Even though many cities have recycling programs, a lot of trash still ends up in the dump. Find out which materials will break down and which materials won't. Will the results of this experiment change which products you often buy? Read more

The Wagon Wheel Effect

Science Fair Project Idea

Scientific Method

Have you ever seen a video where it looked like a car's wheels were spinning backward even though the car was driving forward? What about helicopter blades that looked like they were spinning very slowly, or even not moving at all? This illusion is called the "wagon wheel effect," named after old movies where it looked like wagon wheels were spinning backward. In this science project you will learn how the wagon wheel effect works and how you can film it yourself. Read more

Do Preferences Bias Our Choices?

Science Fair Project Idea

Scientific Method

What is your favorite color and why? Do you think that simple tasks might be biased by your preferences? Find out in this science project if your color preferences will bias your fine motor skills when doing quick, repetitive tasks. 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

Conduct Galileo's Famous Falling Objects Experiment

Science Fair Project Idea

Scientific Method

Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more

Give It a Lift with a Lever

Science Fair Project Idea

Scientific Method

Did you know that you can lift an object that's heavier than you are? Just use a lever! In this science project you'll build a tabletop lever and measure how much effort it takes to lift an object using it. Read more

Test and Change the Air Quality of Your Environment

Science Fair Project Idea

Scientific Method

Do you ever wonder if the air inside is cleaner or dirtier than the air you breathe outside? In this science experiment, you will test it using an air quality monitor. Have you ever wondered how lighting a candle in your room impacts your air quality? Did you cook and not turn on the fan? How did it affect your breathing, and how did it impact the air quality? In this project, you can see how these environmental factors can improve or worsen the air you breathe every day. Read more

Is That Really Bacteria Living in My Yogurt?

Science Fair Project Idea

Scientific Method

Have you ever noticed that most yogurt containers say they contain "live cultures"? What does that mean? The label is suggesting that the yogurt has living bacteria in it! While some types of bacteria can make you sick, some are actually important to keep you healthy. But individual bacteria are so tiny that you cannot see one with the naked eye, so how can you tell if bacteria are really living in your yogurt? In this science fair project, you will investigate whether yogurt actually… Read more

Building Personal Medicine Apps to Help Patients

Science Fair Project Idea

Engineering Design Process

Remembering to take medication or perform a test regularly, consistently, and at specific times can be difficult for elderly people with short-term memory loss, or teenagers absorbed in activities. With mobile devices becoming our constant companions, could a smartphone or tablet offer a solution? The Massachusetts Institute of Technology (MIT) has created a simple tool making it possible for anyone who has a computer and Internet access to create a reminder app. It is easy, quick, and… Read more

Cold Room? Heat It Up with A Homemade Solar Air Heater

Science Fair Project Idea

Scientific Method

What do humans need to survive? We need food, water, and warm shelter. We all need a warm place to live, particularly when it's chilly outside. How do many of us warm our houses or apartments? We depend on fossil fuels to supply gas and electricity to our heaters. But burning fossil fuels to create energy is harmful to the environment. What if there was a way to warm our homes without burning fossil fuels and it was free? In this science fair project, you will build a solar air heater and see… Read more
