Science Fair Project Idea
Scientific Method
Standing on a balcony near the top of the Tower of Pisa in Italy, a young scientist dropped two balls into the crowd below. The scientist, young Galileo, was not trying to knock his fellow professors on the head, but was trying to prove his theory that all objects fall to earth at the same rate, regardless of their mass. Was Galileo's theory correct? In this science project, you will get to test it out for yourself! Look out below! Read more

Scientific Method
Have you ever bitten into a beautiful golden-brown cookie only to realize in dismay that the bottom is burned and black? What causes that uneven baking? Can it be prevented? You can discover the answer by conducting a science fair project to determine whether different types of cookie sheets result in noticeably different cookies. First you'll need to do some background research to figure out what kinds of baking sheets you can buy. For example, there are aluminum, steel, insulated, and… Read more

Scientific Method
Have you ever heard someone say that the moon is made of cheese? Even though the craters on the surface of the moon resemble holes in Swiss cheese, we know that this common myth is not true. Find out how craters are formed and why they are different sizes by doing this simple science project. Read more

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

Do you enjoy playing video games? Do you like the challenge of reaching a difficult game level and scoring lots of points? Video games include many graphic elements that are great to watch, but did you know that not only sighted people enjoy video games? Blind and visually impaired players can also play video games by relying on sound cues — the pings, pops, bangs, and bursts of music that make a game fun or exciting. When building a game that will be accessible to differently abled… Read more

Scientific Method
In this cricket-inspired engineering challenge, you will build a machine to launch a ball and knock down a target (called a wicket). How many times can you knock down the wicket in three minutes? Teachers, lesson plan versions of this challenge are also available. Read more

Scientific Method
Animals have different levels of activity depending upon their habitat, metabolism and behavior. Diurnal animals are more active during the day. Nocturnal animals are more active at night. Being diurnal or nocturnal may have different advantages for different animals. For example, desert animals tend to be nocturnal so they can stay cool and escape the desert heat present during the day. What types of diurnal and nocturnal animals are common in your area? You can set out a small trap to… Read more

Engineering Design Process
Alzheimer's disease and dementia affect millions of people around the globe. Can you design a "brain training" game that can help people keep their brains healthy as they age, and maybe one day help treat or even prevent diseases like Alzheimer's? Try this coding science project to find out! Read more

Engineering Design Process
There are many different kinds of slime out there. Some slime is runny and liquid-like; other slime is thick and rubbery. Some slime glows in the dark, some is fluffy, and some is even magnetic! What set of properties makes the best slime? What kind of slime would you choose to make if you were selling slime as a toy in your own "slime shop"? In this project, you will experiment with different slime recipes and try to perfect one to make the best slime. Read more

Scientific Method
Have you ever noticed that the salt you are using says it is "iodized"? Iodine is an important micronutrient, which means we need it in small quantities to be healthy. Because iodine is rare in many people's normal diets, it is added to table salt. Then when people salt their food, they are also adding this important micronutrient. In this food science project, you will use some kitchen-friendly chemistry to investigate which types of salt have iodine added (in the form of iodide) and which do… Read more
