Craters and Meteorites

Science Fair Project Idea

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

Creating a Kidney: How Stem Cells Might Be Used to Bioengineer a Vital Organ

Science Fair Project Idea

Scientific Method

The human kidney is the most commonly transplanted organ in the United States, numbering more than 17,000 transplants in 2010 alone! But kidney transplantation technology faces a lot of challenges, including a shortage of kidney donors and the need for recipients to take immunosuppressant drugs to keep their bodies from rejecting a transplanted kidney. In this science project, with the help of bioinformatics databases, you will explore how a kidney could be bioengineered using stem cells,… Read more

Crime Scene Chemistry: Determine the Identity of an Unknown Chemical Substance

Science Fair Project Idea

Scientific Method

Picture this situation: An elderly woman is rushed to the hospital complaining of severe abdominal pain, tinnitus, and lethargy. Suspecting a drug interaction, the emergency room doctor starts questioning her. The doctor learns that the woman takes no medicines except aspirin for her arthritis. Since she cannot swallow pills well she takes a powdered form of aspirin which she buys in bulk and keeps in a plastic container in her kitchen next to her baking goods. She had just finished a day of… Read more

Design Your Own Smart LED Lighting System

Science Fair Project Idea

Engineering Design Process

Have you ever had lights turn on automatically when you walked into a room? Have you turned on a light with your voice instead of a switch? Maybe you have even seen lights that change color depending on temperature, ambient sounds, or how close you are to something. In this project you will design and build your own smart LED lighting system that can change colors and react to various things in the room. The possibilities are endless! Check out this page for more LED science projects. Read more

Design Your Own Virtual Reality Headset

Science Fair Project Idea

Engineering Design Process

Virtual reality (VR) headsets are becoming increasingly popular with consumers for things like viewing 3D pictures and videos, or for playing video games. However, dedicated gaming headsets like the Oculus Rift® and PlayStation® VR can cost hundreds of dollars. Some headsets, like Google Cardboard™, which is literally made out of folded corrugated cardboard (Figure 1), are much cheaper because they can use any smartphone as the screen. Figure 1. A… Read more

How do drones automatically hover at a constant distance from the ground? Find out in this fun drone project as you build an altitude control circuit for a popsicle stick drone using an ultrasonic distance sensor and an Arduino™. See this page for a complete list of our mini drone projects. You may wish to do the projects in order. Read more

Do Video Game Players Have Faster Reaction Times Than Non-Players?

Science Fair Project Idea

Scientific Method

When someone yells, "Think fast!" and throws you a ball, are you able to catch it? When the bell rings at the end of class, are you the first one out of your seat? Can you make it through a sudden hairpin turn in a video game without crashing? If so, then you likely have quick reaction times. In this science fair project, you'll look at reaction times (how fast people react to sensory events), and see if people who play video games have faster reaction times than those who do not.

Does Sense of Touch Impact a Cat's Behavior?

Science Fair Project Idea

Scientific Method

Have you ever seen a cat slowly move its head and whiskers into a small space before crawling through it? They’re using their sense of touch to see if they can fit into the space! In this science experiment, you’ll test how cats use their sense of touch to move through the world by using a maze to determine if they prefer big or small spaces. Read more

Have you ever wondered how a musical instrument produces the beautiful sounds that it does? To make a certain note, the instrument has to make a certain sound wave. Depending on the instrument, the sound wave that is made can be affected by changing the length of part of the instrument, such as the strings in a piano or on a guitar, or a trombone’s air column. In this science activity, you will make your own musical instruments using drinking straws and explore how changing the length of the… Read more
