How Blue is Your Sports Drink?

Science Fair Project Idea

Scientific Method

Do you read the list of ingredients in foods and drinks before you buy them at the grocery store? If you do, you may have noticed that many of the items, especially colored drinks, contain dyes with names such as FD&C Blue 1, Red 40, or Yellow 5. But how much dye is needed to create all these colors? In this chemistry science project, you will build a simple spectrophotometer that is able to measure the concentration of colored chemicals in solutions. You will test your device by measuring… Read more

Learn How to Disinfect Contaminated Water

Science Fair Project Idea

Scientific Method

Have you ever thought about how fortunate you are to have safe and clean water coming out of your faucet? Many people in undeveloped nations don't have this luxury. But does that mean they can't have clean water at all? Is there an inexpensive way they could use to make their own clean water? In this microbiology science fair project, you will investigate whether or not sunlight can disinfect contaminated water. Read more

Measuring Surface Tension of Water with a Penny

Science Fair Project Idea

Scientific Method

Did you know that even though water is a liquid, it isn't always able to get into little cracks and crevices? So how do clothes go from caked with mud to clean? How can dishes go from greasy to glistening? With a few simple household items, you can find out! Read more

Paper Chromatography: Is Black Ink Really Black?

Science Fair Project Idea

Scientific Method

Have you ever looked at sunlight through a prism? If so, you know that the prism can separate the sunlight into many different colors of light — a rainbow. Like sunlight, chemical mixtures can also be broken into their component parts. One way of doing this is a simple technique called paper chromatography. What do you think you will see if you use paper chromatography to look at the components of black ink? Is black ink just black? Find out for yourself! Read more

Teach Newton's Laws of Motion

Blog Post

Use these free STEM lessons and activities to teach about Newton's laws of motion. Newton's Laws of Motion in the K-12 Classroom Across all grade bands, students explore science related to forces, motion, and interactions between objects; concepts that use Newton's laws of motion as a fulcrum for understanding forces and motion; inertia and equilibrium; the relationship between mass and acceleration; the difference between acceleration and velocity;… Read more

Which Skin Moisturizer Works Best?

Science Fair Project Idea

Scientific Method

Does your skin get dry? Or do you know someone with dry skin? Dry skin can be a real medical problem for some people. You may have seen many kinds of lotions, creams, and ointments advertised as restorative for dry skin, especially dry hands. But how well do they work? And which ingredients are most important in making them work? In this science project, you will create a model of human skin using JELL-O® and test how well skin moisturizing products with different ingredients keep the model… Read more

Creating a Kidney: How Stem Cells Might Be Used to Bioengineer a Vital Organ

Science Fair Project Idea

Scientific Method

The human kidney is the most commonly transplanted organ in the United States, numbering more than 17,000 transplants in 2010 alone! But kidney transplantation technology faces a lot of challenges, including a shortage of kidney donors and the need for recipients to take immunosuppressant drugs to keep their bodies from rejecting a transplanted kidney. In this science project, with the help of bioinformatics databases, you will explore how a kidney could be bioengineered using stem cells,… Read more

How Does Color Affect Heating by Absorption of Light?

Science Fair Project Idea

Scientific Method

Why is it more comfortable to wear light-colored clothes on a hot summer day? Why wear a dark-colored jacket for early-morning fishing on a cold lake? How much difference can it make? Here's a project where you can quantify how much difference color makes for absorbing heat. Read more
