Build a Zippy Line-following Robot (BlueBot Project #3)

Science Fair Project Idea

Engineering Design Process

How easy is it for you to walk along and follow a line that is painted on the ground? Simple, right? You might be able to follow a line without giving it much thought, but how could a robot do that? In this project, you will build your own automatic line-following robot that can race around a track that you create. This technology has plenty of real-world applications—maybe one day you could help design self-driving cars! Read more

Can You Train People to Breathe Better?

Science Fair Project Idea

Scientific Method

The practice of "belly breathing" has been linked to improve mood, relaxation, and even have physical benefits like lowering your heart rate when compared to chest breathing. However, most of the time, we do not think about breathing—our bodies do it automatically. How do you know if you are belly breathing instead of chest breathing? How can you practice and get better at it? In this project you will build your own device to provide visual feedback about how a person breathes, then see… Read more

Discover Chlorophyll Variety in Different Plants Using Paper Chromatography

Science Fair Project Idea

Scientific Method

Do you like to analyze stuff and finding out what it is made of? An analytical chemistry method, called chromatography, allows you to separate mixtures of compounds and to identify each individual compound within the mixture. Chromatography is used by many scientists, for example food scientists, forensic scientists, or organic scientists to analyze all kinds of mixtures such as food, blood, or medicine. In this project, you will be using paper chromatography to analyze the pigments from… Read more

DNA Fingerprinting

Science Fair Project Idea

Scientific Method

Are you interested in the technical and ethical aspects of genetic screening, forensic science, and DNA fingerprinting? Scientists use different forms of a gene, called alleles, to differentiate between two fingerprints. One such sequence used in human DNA fingerprinting is the Alu repeat (a 300 base pair repetitive sequence of DNA) on chromosome 16. During evolutionary time, up to 1 million copies of the Alu repeat have become randomly inserted throughout the human genome. Within a specific… Read more

Exploring DNA Damage: What Effect Do Ultraviolet Rays Have on Yeast Colony Growth?

Science Fair Project Idea

Scientific Method

Though the Sun provides heat and light, which are essential for life on Earth, ultraviolet (UV) rays in sunlight can cause damage to DNA. In this science fair project, you will experiment with a strain of yeast that is super-sensitive to UV light. This project will demonstrate the lethal effects of UV light when DNA damage is not repaired. Read more

How to Control a DIY Mini Drone with an Arduino™

Science Fair Project Idea

Engineering Design Process

Most drones fly with a mix of human input and autonomous control based on feedback from electronic sensors. This allows the drone to fly up and down when the human operator presses a joystick on a controller, but automatically hover at a fixed distance above the ground when the operator lets go of the joystick. In this project, you will explore drone programming with an Arduino. What types of inputs and sensors can you make your drone respond to? What behaviors and responses can you program… Read more

Investigating the 'Mpemba Effect': Can Hot Water Freeze Faster than Cold Water?

Science Fair Project Idea

Scientific Method

This physics project seems like it should have an easy answer. Instead, it turns out to be a great illustration of why it is important to base scientific conclusions on the outcome of controlled experiments. Things don't always turn out as we expect! Read more

Make a Biohybrid Robot

Science Fair Project Idea

Engineering Design Process

When you think of robots, you might think of things made out of plastic or metal...but what about living materials? Living materials have one big advantage: they can heal and repair themselves if they get damaged. Since it might not always be easy to repair a damaged robot (for example, a robot on another planet), some scientists want to figure out how to include living, or biological, materials in them to create "biohybrid" robots. In this project, you will create your own simple biohybrid… Read more

Monitor Your Plants with a Soil Moisture Sensor

Science Fair Project Idea

Scientific Method

Do you or your family have a lawn, garden, or potted plants that you water regularly? Irrigation—or the artificial application of water to plants and landscaping—accounts for over two-thirds of the world's freshwater consumption (U.S. Geological Survey, 2016)! While that total includes farms, in the United States landscape irrigation still accounts for almost one-third of residential water use. As much as half of that water is wasted due to inefficient watering methods (WaterSense,… Read more

Turn Plants into Biofuel with the Power of Enzymes

Science Fair Project Idea

Scientific Method

Are biofuels the wave of the future? People often talk about these plant-derived fuels as a way to someday cut down on our dependency on non-renewable carbon-based fuels, like gasoline. Ethanol (a type of alcohol) is a common biofuel used today. In the United States, ethanol is a common biofuel additive to normal gasoline. In fact, some states mandate that when you fill up your gas tank, 10 percent of the total fuel volume be made of ethanol. Brazil, the world's second largest user of… Read more
