Science Fair Project Idea
thumbnail Watching a space shuttle launch is an unforgettable experience. Solid fuel rocket boosters and the engines both overcome the massive weight of the shuttle, and even gravity, to blast a space shuttle into space. One issue with solid fuel rocket boosters and conventional rocket engines is that they require fuel, and fuel weighs a lot! In this electronics and electricity science fair project, you will learn about ion engine propulsion systems. These systems have advantages over the conventional… Read more

Science Fair Project Idea
thumbnail If you have ever been shot with a rubber band then you know it has energy in it, enough energy to smack you in the arm and cause a sting! But just how much energy does a rubber band have? In this experiment you will find out how the stretching of a rubber band affects the amount of energy that springs out of it. Read more

Science Fair Project Idea
thumbnail Have you ever seen or heard of the movies The Mummy or The Mummy Returns? Mummies have always played a part in nightmares for Western cultures, but in ancient Egypt, mummification was a serious religious ritual. They believed that preserving human remains was necessary so that the previous owner could enjoy the fruits of the afterlife. In this science fair project, you will learn about the rituals and science of mummification by mummifying a hot dog. Read more

Science Fair Project Idea
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

Science Fair Project Idea
thumbnail Every criminal leaves behind evidence at the crime scene. The trick to catching the criminal is collecting all of the evidence and making sense of it. This is what the forensic expert does. In this science project you will be correlating the size of blood stains to the distance they fell, but do not get too grossed out. You will be doing it with fake blood. If you like figuring out mysteries, this is the science project for you! Read more

Safety This topic can be a little scary. If you are squeamish, you may want to choose another topic. Adult supervision is required when doing background research, especially online, on this topic.
Science Fair Project Idea
thumbnail Have you ever gotten a shock touching a doorknob after walking across a carpet? Static charge is responsible for that shock. Wouldn't it be cool to save up and store all of that charge in a homemade jar? It would almost be like storing lightning. This science project will show you how to do that. Read more

Cost Average ($50 - $100)
Safety Since this experiment deals with electricity, it is best to have an adult supervise. A mild to moderate electric shock is possible if care is not taken. Follow all directions as stated.
Science Fair Project Idea
thumbnail 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
Phys_p081

- Less Details
Time Required Average (6-10 days)
Prerequisites None
Material Availability Specialty items including neodymium magnets and steel ball bearings are needed for this project. See the Materials and Equipment list for details.
Cost Low ($20 - $50)
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.
Science Fair Project Idea
thumbnail Generating power from mud sounds like science fiction, but it is actually real science, and a promising source of alternative energy. Topsoil is packed with bacteria that generate electricity when placed in a microbial fuel cell. Because such bacteria-laden soil is found almost everywhere on Earth, microbial fuel cells can make clean, renewable electricity nearly anyplace around the globe. They are an up-and-coming technology that scientists and engineers are working on making even more… Read more

Time Required Very Long (1+ months)
Prerequisites Having used a voltmeter/multimeter before is helpful, but not required.
Material Availability The microbial fuel cell kit needs to be special ordered from the [# Link Name="Elec_p071.7" Value="HtmlAnchor" #].
Cost Average ($50 - $100)
Safety Be sure to wear the gloves supplied with the kit when handling the microbial fuel cell's electrodes (its cathode and anode). The electrodes are made of a conductive material called graphite fiber and should not be placed near electronics, power plugs, or have their fibers dispersed in the air. The fibers will cause electrical shortages when in contact with electronics.
Science Fair Project Idea
thumbnail Alka-Seltzer® tablets fizz furiously when dropped into water. The moment the tablet starts dissolving, a chemical reaction occurs that releases carbon dioxide gas. Can you make Alka-Seltzer fizz faster or slower by changing the temperature of the water? How big of a difference in the rate of a chemical reaction can temperature make? Read more
