An Experiment on Nitrogen Fertilizers
Science Fair Project Idea
Scientific Method
Plants need nitrogen to grow healthy stems and leaves. Although nitrogen is the most abundant element in the air we breathe, that form of nitrogen cannot be used by plants. Nitrogen contained in fertilizer, on the other hand, is readily taken up by plants. In this experiment, you will compare plants grown without nitrogen fertilizer to plants grown with nitrogen fertilizer. Read more
Yogurt Cultures
Science Fair Project Idea
Scientific Method
Have you ever wondered how yogurt is made and what makes some yogurts different from other yogurts? You may have noticed that most yogurt containers advertise that the yogurt contains "live cultures." This means that there are living bacteria in the yogurt! These amazing bacteria can turn plain old milk into a yummy yogurt treat. In this science project, you will investigate whether the bacteria affect what the yogurt feels, tastes, and smells like by making your own yogurt at home! Read more
Want to Make a Video Game? Here's How!
Science Fair Project Idea
Engineering Design Process
Do you love playing video and computer games? Do you dream of someday creating your own? With this science fair project you can turn that "someday" wish into a "today" reality! Read more
What Materials Can Block a Wi-Fi Signal?
Science Fair Project Idea
Scientific Method
Have you ever suffered from poor Wi-Fi reception for your smartphone, tablet, or laptop? Certain materials can actually block a Wi-Fi signal; do you think that could be part of your problem? In this science project, you will do an experiment to find out which materials cause the biggest drop in signal strength from a wireless router. Read more
Rubber Bands for Energy
Science Fair Project Idea
Scientific Method
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
The Physics of Artificial Gravity
Science Fair Project Idea
Scientific Method
How can we make space stations with artificial gravity a reality? In this science project, you will explore the physics of creating artificial gravity with circular motion. Read more
Pop Goes the Metal: How Temperature Affects Snap Time of a Jumping Disc
Science Fair Project Idea
Scientific Method
Jumping discs can be a fun toy to play with, and with their sudden POP!, they can even be a good way to startle people who have never heard them before. Jumping discs use a neat trick to jump. They are made of two different types of metal, and these metals expand when they heat up (or shrink when they cool down), but not by exactly the same amount. In this science project you will explore how temperature affects the reactions of your jumping discs— and how to get the timing right if you… Read more
Spread the Soap, Not the Germs
Science Fair Project Idea
Scientific Method
Do you wash your hands? You should— it's the best way to prevent the spread of germs. But germs can be tricky; they find nooks and crannies to hide in, so it takes good hand-washing technique to get rid of them. In this science project, you'll investigate which parts of the hand are the most difficult to wash germs off of. Read more
Are There Bugs Under Your Feet?
Science Fair Project Idea
Scientific Method
Look out! When you walk on the grass, you are squishing millions of micro-invertebrates! Just kidding, these animals are too small to squish. Learn how to catch them by making a Berlese funnel in this fun project that will teach you about soil. Read more
Modeling the Chances of Getting an Autoimmune Disease
Science Fair Project Idea
Scientific Method
Do you know someone who has an autoimmune disease? Autoimmune diseases are fairly common, affecting more than 23.5 million people in the United States, which is about 1 in 13 people! You may have heard of some of them, such as diabetes (type 1), rheumatoid arthritis, and celiac disease. Many autoimmune diseases are poorly understood, but they all have one thing in common: they happen because a person's immune system (which normally fights off germs to keep the person healthy) attacks the… Read more
