Irrigation, or the artificial application of water to crops, has been used by humans for thousands of years. Ancient civilizations build complex irrigation systems without the aid of modern technology or construction equipment. Can you design a model irrigation system using some simple household materials?

Build Statues That Come Alive When They See You

Science Fair Project Idea

Scientific Method

A simple circuit and a servo motor are all you need to turn any work of art into an interactive moving creation that is happy to see you. Light sensors see your shadow as you walk past your artwork and make a servo motor move back and forth. Waving arms? Turning heads? It is all up to you! 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

Can the Color of Your House Reduce Your Energy Footprint?

Science Fair Project Idea

Scientific Method

Did you know that the color of your house could save money? Do this experiment to see which colors regulate temperature best in different environments. Then convince your parents to paint the house and save some money on their energy bill. Maybe they will be so happy they will also increase your allowance! Read more

Can You Predict a Bird's Lifestyle Based on Its Feet?

Science Fair Project Idea

Scientific Method

Animals survive in all sorts of extreme environments, whether it is a polar bear out and about when it is -40°F, a desert iguana trying to find food as the temperature rises to 110°F, or a deep sea anglerfish living 3281 feet down into the sea. How do they do it? The answer is adaptations! Their bodies have special features that allow them to live in those environments. You might not be able to dive down 3281 feet to observe the deep sea anglerfish, but in this science fair project you… Read more

Can Your Body Temperature Tell the Time of Day? Find Out with Human Circadian Cycles.

Science Fair Project Idea

Scientific Method

Have you ever had to adjust to a new time zone and noticed that it takes a while before you start to feel normal again? By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms. Human beings, like many other living things, have a number of internal processes that show a distinct circadian rhythm. The most obvious is our sleep cycle, with activity during the day, followed by sleep during the night. Circadian rhythms have also been demonstrated… Read more

Candy Corn Geodesic Dome

Blog Post

A classic science (and geometry) project takes on Halloween tones with candy corn-colored candies, a few ordinary toothpicks, and a bunch of triangles. We are big fans in my house of the geodesic dome. We initially tried a bigger-than-expected version made from straws a few years ago. We had a great time putting it together—but it would not fit through the front door! Making a small-scale geodesic dome from gummy candies is a much easier and… Read more

Center of a Shape Science

Blog Post

In this family STEM activity, students experiment with a simple technique that can help them determine the center of a shape. Grab some paperclips and string to explore! In this week's family science activity, students learn how to find the "middle" or "center" of a two-dimensional shape. It can be easy to locate the center of a symmetrical shape like a circle or a square, but finding the middle of an irregular shape can seem tricky. With a bit of science, kids can pinpoint the center of any… Read more

Have you ever wondered why your phone, computer, or a flashlight works without being plugged into a power outlet? Where does the electrical energy come from that makes all these portable devices function? You probably know the answer: they use batteries! But do you know how these batteries work? Batteries store electrical energy in the form of chemical energy, which means that electrochemical reactions inside the batteries create electricity. It may sound complicated, but it is simpler than you… Read more

Chlorophyll Extraction

Science Fair Project Idea

Scientific Method

Chlorophyll is a natural pigment found in green plants. It is the primary pigment that absorbs light energy from the sun for photosynthesis. This energy is then used by the plant to synthesize glucose from carbon dioxide and water. Chlorophyll in the leaves of plants can be extracted and separated using chromatography. A good source of chlorophyll for an extraction is a dark green leafy vegetable like spinach. Rub a fresh spinach leaf on the bottom of a strip of filter paper. You can get a… Read more
