Candy Chromatography: What Makes Those Colors?

Science Fair Project Idea

Scientific Method

Quick, what is your favorite color of M&Ms® candy? Do you want to know what dyes were used to make that color? Check out this science project to find out how you can do some scientific detective work to find out for yourself. Read more

Crazy Crystal Creations: How to Grow the Best and the Largest Crystals

Science Fair Project Idea

Scientific Method

Crystals come in all different shapes and sizes. However, the purest and cleanest crystals are usually also the ones that grow to be the largest in size. In this science fair project, you will compare the size and shape of crystals grown in three different temperature conditions: room temperature, in the refrigerator, and in an ice bath. With just water and borax, a household cleaning product, you can discover the best recrystallization method for growing large, pure crystals. Read more

Does Color Affect Taste?

Science Fair Project Idea

Scientific Method

You might have heard the saying "The eyes eat before the mouth." The appearance of food, especially its color, certainly affects how we perceive its taste. But can your eyes actually change the way you taste something? In this science project, you will find out by investigating how people perceive the taste of different colored apple juice. How do you think color affects taste? Read more

Have you ever wondered why leaves change from green to an amazing array of yellow, orange, and red during the fall? Leaves get their brilliant colors from pigments made up of various color-creating molecules. During the warm, sunny months, plants use their leaves to turn sunlight into food energy, a process called photosynthesis. This primarily uses a pigment that reflects green light, which gives the leaves their characteristic color. In autumn, when colder, shorter days arrive, many kinds of… Read more

Do you think plants can grow without soil? If you've tried growing vegetables, you probably planted the seeds or seedlings in soil. Soil gives the plants the nutrients they need to grow. However, plants can grow without soil, too, using a process called hydroponics. In this activity, you will transform a bottle into a mini-garden that needs only light, air, and nutrient-rich water to grow! Read more

Lift a Load Using Hydraulics

Science Fair Project Idea

Scientific Method

Can you lift a car? No? You say you are not strong enough? True, our bodies are not built to lift heavy loads like cars. Fortunately, our brains are smart enough to harness the power of fluids, like water and oil, to create hydraulic lifts. By pushing a button on a hydraulic lift, a mechanic can easily raise a car with one finger. Lifts can also be used to raise lots of other heavy loads - even such massive things as steel girders to construct a skyscraper! In this mechanical engineering… Read more

Make an Origami Robotic Gripper

Science Fair Project Idea

Engineering Design Process

Do you like making paper airplanes? What about origami animals? Have you ever thought about making a paper robot? In this engineering project, you will make a three-dimensional robotic gripper that starts out as a single flat sheet of paper! Try it out—see what objects you can pick up with the gripper, then see if you can improve the design. Read more
