Science Fair Project Idea
thumbnail Practice makes you better at most things, and knowledge makes practice so much easier! Can you swirl a circular toy called a hula hoop around your waist or arm? Is it hard? What knowledge can you apply to find ways that make hula-hooping easier? Physics! Yes, physics will help you determine what makes one hula hoop a winner and another a flop. In this science project, you will create your own hula hoops, spin them, and draw conclusions. The road will then be open to your becoming a hula hoop… Read more

thumbnail Do you enjoy going stargazing? In a good location on a clear night, you can see a huge number of stars twinkling in the night's sky. Have you ever wondered how far those stars are from us? Ancient astronomers actually discovered a way figure this out, measuring the distance from Earth to faraway stars. How did they do it without modern technologies? In this astronomy science project you will find out by exploring the link between the distance of an object and perspective (also known as… Read more

thumbnail "Hey kids, step right up! Toss this ball and win a prize!" shouts the carny barker. Sounds easy enough—until you try it. Why are those "simple" games at the fairs, carnivals, and boardwalks so hard? Is it really lack of skill or coordination or do those concessionaires use some basic laws of science to help them set up the games in their favor? This science fair project can help you find out for yourself. Read more

thumbnail 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… Read more

thumbnail If you've ever played or watched basketball, you might already know that your chances of successfully banking a shot on the backboard are higher in certain positions on the basketball court, even when keeping the distance from the hoop the same. Ever wondered what would account for this? Do you think you could actually explain this using geometry? This science project will put your knowledge of geometry and algebra to good use. You will calculate and quantify how much more difficult it is to… Read more
