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

A Battery That Makes Cents

Science Fair Project Idea

Scientific Method

Batteries are expensive, but you can make one for exactly 24 cents! In this experiment, you will make your own voltaic pile using pennies and nickels. How many coins in the pile will make the most electricity? Read more

Dealing with Diabetes: The Road to Developing an Artificial Pancreas

Science Fair Project Idea

Engineering Design Process

Imagine if you had to take medicine every time you ate, and you had to use a math formula to figure out how much medicine to take based on the nutritional makeup of the food, how you were feeling, and what activities you were planning to do. You might also need extra medicine throughout the day (even in the middle of the night) based on your blood glucose levels. People with diabetes who take insulin do this every day. They use finger sticks and blood glucose meters or a continuous glucose… Read more

Forensic Science: Building Your Own Tool for Identifying DNA

Science Fair Project Idea

Scientific Method

When biologists want to separate different pieces of DNA, RNA, or proteins they use a technique called gel electrophoresis. In this science project you'll build a gel electrophoresis chamber and use it to discover how many components are in different colors of food coloring dye. Read more

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
