How Are Antibodies Used for Blood Typing?

Science Fair Project Idea

Scientific Method

Have you ever heard about different blood types? Do you know what your blood type is? Antibodies help scientists determine different human blood types. This project is a practical introduction to the human immune system in which you will learn about what antibodies are, how they are formed, and how they can be used to identify different types of cells.

Tornadoes

Science Fair Project Idea

Scientific Method

Tornadoes are a very destructive weather phenomenon that is very hard to predict. Certain weather conditions can indicate if a tornado is likely to occur, but the path that the tornado will take is completely unpredictable. Storm chasers are people who chase tornadoes and try to capture them on film or video. They often have a sense of predicting where and when a tornado will strike, but the best images are also due to a bit of luck and survival instinct. Even though tornadoes are… Read more

Do-Re-Mi with Straws

Science Fair Project Idea

Scientific Method

Do you love to make music, but do not have access to all the instruments you would love to play? Check out this fun science fair project about the physics of musical sound production. You will make musical instruments with drinking straws, one for each note on a one-octave major scale. Can you figure out the right lengths for a series of straw "oboes" in order to play a musical scale? Read more

Which Bait Works Best for a Homemade Fly Trap?

Science Fair Project Idea

Scientific Method

Do you really catch more flies with honey than with vinegar? Do an experiment to find out! Watch the video above to learn how to make a simple homemade fly trap using a plastic bottle. Then, experiment to discover which bait attracts the most flies. You can try a variety of liquids, and you can also use solid bait like rotting food or meat, but you will need to add some water so the flies drown. A drop of soap can help break the surface tension of the water, making it easier for the flies to… Read more

That's a Real Smile! ...or is it?

Science Fair Project Idea

Scientific Method

If someone is smiling, it means they're happy, right? Well, not always. Sometimes people smile to be polite, or because they want to "appear" happy or friendly for social reasons. How easy is it to spot which smiles are genuine and which are fake? Try this science fair project to find out! Read more

Explore Perceptrons: A Simple Type of Neural Network

Science Fair Project Idea

Engineering Design Process

Have the phrases "machine learning" or "neural network" caught your interest, but you are not really sure how to use them in a science project? This project is a great place to start for beginners. You will learn about a very simple type of neural network—a computer program modeled after the human brain—called a perceptron. The perceptron can make a simple yes/no decision based on several inputs. You can "train" your perceptron to improve its decision-making abilities. Try it and… Read more

Go and Stop? Ant Traffic Signals

Science Fair Project Idea

Scientific Method

Have you ever stopped to watch a trail of ants moving back and forth between a food source and their nest? Have you ever wondered how they establish their trail? You've probably read that ants use chemical signals to communicate with one another. This is a relatively simple experiment that you can do to determine whether ants use attractant signals (positive cues) or repellant signals (negative cues) or both. Read more

Measuring the Oxygen Content of Air

Science Fair Project Idea

Scientific Method

Earth's atmosphere, the ocean of air that blankets the planet, is mostly nitrogen and oxygen, with small amounts of other gases. How much oxygen is present in air at sea level? In air high up in the Appalachians or Rockies? Atop Mount Everest? How much oxygen is present in the air you breathe? Here's a project that shows you how to measure the percentage of oxygen in an air sample. Read more

Effects of Exercise: Changes in Carbon Dioxide Output

Science Fair Project Idea

Scientific Method

You might know that your body needs oxygen to keep going, and that you breathe out carbon dioxide as waste. What happens when you exercise? You have probably noticed that you breathe faster, and your heart beats faster. What triggers your body to respond in this way? How does it "rev up" to keep your muscles going? In this project, you will get a peek into the fascinating science of exercise physiology and find out—with the help of a color changing reaction. Read more

Solid Motor Rocket Propulsion

Science Fair Project Idea

Scientific Method

What does it take to launch a robot to Mars or for a satellite to explore our outer solar system? In this project you will explore the physics of a rocket as you predict its performance, launch it, and measure the actual results. This is rocket science! Read more
