Science Fair Project Idea

Scientific Method

Electric paint is a fun way to include a circuit with lights in an art project, but it presents a challenge not found in traditional electronic circuits. What happens if you change the length or width of your strokes of paint, such as by painting longer, curvier lines or using a thicker brush? Could this affect the electrical properties of your circuit? Try this project to find out! Read more

Excess Volume: Investigate the "Shrinking Liquids" Effect

Science Fair Project Idea

Scientific Method

Cooking, washing, and many industrial processes involve the mixing of liquids. How liquids behave when they are mixed is dependent on many factors. Sometimes, the mixing behavior of liquids can be quite surprising! For example, when you mix 50 mL of one liquid with 50 mL of another liquid, you might not end up with a 100 mL mixture! In this science project, you will explore this phenomenon, which we call the "excess volume" of mixtures. How do you think your mixing volumes will… 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

Have you ever seen or heard of the movies "The Mummy" or "The Mummy Returns"? Mummies have often played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual thought to be necessary for a person to enjoy the afterlife. In this activity, you will learn about the science behind the process of mummification by mummifying a hot dog. Read more

Exploring the Impact of Social Media on Mental Health with Machine Learning

Science Fair Project Idea

Scientific Method

Do you ever wonder if you spend too much time online? How can the amount of time spent on social media influence someone's mental health? What other factors play a role? In this science project, you will investigate which variables correlate with better mental health scores using a machine learning algorithm called the Random Forest algorithm. Read more

Feel Sound With Your Fingertips: Ultrasonic Haptics

Science Fair Project Idea

Scientific Method

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair. Read more

Students explore how force, mass, and acceleration are related in this hands-on lesson plan. By experimenting with pushing a box across the table while varying force and mass and measuring the box's acceleration with a mobile phone and a sensor app, students discover Newton's second law of motion for themselves.

NGSS Performance Expectations:

HS-PS2-1. Analyze data to support the claim that Newton's second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.

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.

Give Yourself a Lift: Lightening the Load with Pulleys

Science Fair Project Idea

Scientific Method

Before the Industrial Age, people relied on muscle power for moving and lifting heavy objects. Here's a project that shows you how you can use your head to make heavy lifting easier on your muscles–and your back! Read more

Grow Vegan Kombucha Leather

Science Fair Project Idea

Scientific Method

Do you love the look and feel of leather? Many luxury items like handbags, belts, wallets, and coats are made from leather. What if you could make your own vegan leather in a few weeks? Could it be a greener, more sustainable option than cowhide leather? In this science project, you will grow your own vegan leather from kombucha and see how different growing conditions affect the resulting leather. Read more
