Science Fair Project Idea
Scientific Method
There is evidence to be gathered at every crime scene. The hard part is making sense of it all. That's where crime scene investigators and forensic scientists come in. In this science fair project, you will investigate blood spatter using fake blood. Your job, as an impartial scientist, is to deliver facts so that justice can be served. Are you up to the challenge?

Scientific Method
Have you ever watched your parents dress up for a big evening? They may even splash on a bit of aftershave cologne or dab on some perfume since it is special occasion. But did you know that using perfume and scents is an ancient activity? Perfumes and the art of making perfume is an art that is thousands of years old. In this chemistry science fair project, you will learn more about one way to make perfume, called enfleurage, and experiment with it to extract your own floral scents. Read more

Engineering Design Process
Underwater robots, or remotely operated vehicles (ROVs), help us explore areas of the ocean that can be dangerous for humans. They can provide valuable scientific information about deep-sea life and ocean climate. However, you do not need access to the ocean to build and test your own ROV. If you have ever wanted to build your own ROV but were not sure where to start, the SeaPerch platform is a great option. You can purchase a complete kit with all the required parts and follow the detailed… Read more

Scientific Method
"Flu season" is something we deal with every winter. Cyclical or seasonal outbreaks of an infectious disease can occur for a variety of reasons, such as seasonal changes in host behavior (for example, more people staying indoors), the seasonal abundance of disease carriers (for example, mosquitos), and many others. Another factor that can play a role in cyclical outbreaks occurs when the natural immunity to a disease has a short duration. This enables each individual in the population to… Read more

Engineering Design Process
Have you ever wondered what the air currents look like around a candle? What about cold air flowing around an ice cube, or warm air rising from your hand? What about when you sneeze? We are surrounded by air currents all the time, but these subtle movements are completely invisible to the human eye. In this science project, you will take advantage of small changes in air density to make air currents visible in regular photographs and videos, using techniques called shadowgraphy and schlieren… Read more

Scientific Method
Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

Scientific Method
Have you ever wondered what it would be like to have an extra sense? What if you could hear above the normal range (ultrasound) like dogs or bats? What if you could see ultraviolet light, like bees or juvenile trout? What if you could see infrared light, like a rattlesnake or boa constrictor? This project shows you how you can use a phone or camera, tripod, and a special filter to take pictures using near infrared illumination. It's a whole new way of looking at the world. Read more
Science Fair Project Idea
Scientific Method
This is an interesting experiment that explores certain aspects of how your brain pays attention. In this project, you'll have to recruit a bunch of volunteers to take a simple test: naming a list of printed shapes. What makes the test tricky is that words will be printed on top of the shapes. The word/shape combination creates the potential for the brain to get conflicting information. Which information is more likely to grab your attention: the shape you are supposed to name or the word just… Read more

Scientific Method
The electricity in your home probably comes from a power plant, but did you know that you can actually generate your own electricity? Wondering what it would take to light up a small light? This is your chance! In this electronics science project, you will build your own electric generator and investigate how to light up not just one, but two lights. Read more
Science Fair Project Idea
Scientific Method
A technique often used in wind tunnels is to introduce smoke in front of the airfoil that is being tested. The smoke comes from regularly-spaced point sources, and the wind flow in the tunnel spreads it out into parallel lines, called streamlines. The streamlines make it possible to visualize the airflow over the airfoil. When the lines continue smoothly over and past the airflow, they show that the flow remains laminar, and that the airfoil is creating very little drag. When the… Read more
