Science Fair Project Idea
Do you like drawing or painting? What if you could build a robot that creates its own art? In this project, you will create your own Art Bot, a robot with markers for "legs" that wobbles across a piece of paper, creating drawings as it moves. You can then customize your robot to change how it draws. This is a beginner-level project with no robotics experience necessary, so if you want to try building your own robot, this is a great place to start! Read more

Does your hair go crazy when the weather turns damp? Did you know that strands of hair can relax and lengthen when the humidity increases and then contract again when the humidity decreases? In fact, hair strands can be used as the basis for a hygrometer, a device which measures the humidity level in the air. Can a human hair hygrometer also detect changes in hair structure caused by chemical lightening? This project shows you how to find out. Read more

Science Fair Project Idea
Maple syrup on pancakes, ripe bananas, and soft drinks are all foods that are tasty to us because of the sugar in them. But did you know there are different kinds of sugar? One food can have multiple kinds of sugar in it, and our bodies actually process the different types of sugars differently. In this science project, you will measure the concentration of two sugars—glucose and sucrose—in different foods, and investigate how sucrose is converted into glucose with the help… Read more

Advertisements for high-tech sports gear or the latest and greatest outdoor material promise lighter and stronger products every season. Is it a scam? How can engineers keep creating materials that are both lighter and stronger than anything known so far? The answer is in the nanoscale! Using nanotechnology, scientists can play around with the detailed structure of matter, leading to a whole new range of materials, some with amazing qualities. In this science project, you will get a glimpse… Read more

Put your engineering skills to the test to see if you can build a machine—powered by nothing but gravity—that will automatically sort out two different sizes of plastic spheres. That might seem like a strange task, but have you ever used a coin sorter to separate pennies, nickels, dimes, and quarters? How about using a sifter in the kitchen to separate fine grains of flour or sugar from bigger lumps? Machines that can automatically sort objects or particles of different sizes are… Read more

Maple syrup is deliciously gooey and great on breakfast foods like pancakes and waffles. But it has another amazing property. It can be turned into maple candies with a range of textures, like sticky maple taffy or molded maple sugar candy. In this science fair project, you will investigate how the temperature that maple syrup is heated up to affects what type of maple syrup-based candies can be made. Read more

Have you ever wondered how your cell phone or laptop keeps running once you unplug it? Sure, it is the battery that makes your portable electronics work, but how exactly does a battery do that, and from where does the electricity come? Generally, in a battery chemical energy is converted into electrical energy. In fact, many different types of batteries exist that are all based on a different set of chemical reactions. In this science project, you will explore a special battery variant called… Read more

Science Fair Project Idea
Have you ever ridden on a carousel, or a merry-go-round, at an amusement park? On a carousel, you usually get to take a seat on a wooden horse or other animal that spins around and around as the carousel is turned on and powered by electricity. Another smaller type of carousel that people can have in their homes is a candle carousel, which is powered by heat from candles. In this science project, you will get to make your own candle carousel and investigate how the spinning speed of the… Read more

Science Fair Project Idea
What can you do with magnets and ball bearings that makes a lot of noise? Why, build a magnetic rifle, called a Gauss rifle, of course! Now, this rifle is not a weapon, but a way for you to learn a lot more about physics concepts, like momentum. In this physics science project, you will investigate how far a ball bearing launched by a Gauss rifle will fly, depending on how many magnetic acceleration stages are in the rifle and the ball bearing's initial velocity. This science project makes for… Read more

Safety A Gauss rifle can produce high velocity projectiles. Do not aim the gun at anyone or anything; do not put your hand in front of the projectile. Operate the Gauss rifle safely. Be sure to read the important safety notes at the beginning of the Experimental Procedure before you begin. Scissors or other metal objects may be attracted to the magnets; use caution when using metal objects near the magnets.
