Germination

Science Fair Project Idea

Scientific Method

Germination is the process by which a seed emerges from the seed coat. Many different variables can effect the process of germination. Try to sprout seeds from different species of plant to see if different species vary in germination time. Are weeds faster germinators than vegetables? Try measuring seeds and then germinating them to see if big seeds sprout at a different rate than small seeds. Try sprouting seeds in different environments to test the effect of different environmental… Read more

Animal Magnetism: Do Large Mammals Align Themselves with Earth's Magnetic Field?

Science Fair Project Idea

Scientific Method

We rely heavily on our senses to tell us about our environment. But in addition to the senses of touch, smell, taste, hearing, and sight, some animals are able to sense Earth's magnetic field. Migratory turtles and birds use this sense to guide them on long journeys. Homing pigeons use it to find their way home. New research suggests that large mammals, such as cows and deer, may also have the ability to sense the direction of magnetic north. In this animal behavior science project, you will… Read more

Macroinvertebrates as Indicators of Pollution

Science Fair Project Idea

Scientific Method

In this science project, you will collect macroinvertebrate samples from multiple points along a body of water, ideally a small creek or stream, and test the pollution burden and biodiversity of small organisms or insects to see if pollution impacts biodiversity. Read more

The Process of Soft-Boiling an Egg

Science Fair Project Idea

Scientific Method

Sometimes on a busy day, it is hard to get things done. The rush to get things done can start first thing in the morning, when you are so busy getting ready and gathering your homework, that you barely have time for breakfast. It takes time to get a nutritious meal ready. But, eggs are a perfect choice for breakfast because they can be cooked quickly and in many different ways. A soft-boiled egg is a choice that many people make. They like the way the thickened, tasty yolk coats their hash… Read more

Geomagnetism

Science Fair Project Idea

Scientific Method

What is geomagnetism, and how does it affect the earth? Visit the USGS Geomagnetism program for more information about this invisible force (USGS, 2006). How is the earth's magnetic field patterned? Are the magnetic poles located at the exact North and South Pole? How can the fields be mapped on the Earth's surface? What is declination? Use the mapping tools to study changes in declination patterns over time. (USGS, 2006) Read more

Does Your Mobile Phone Radiate? Measuring Cell Phone Electromagnetic Radiation

Science Fair Project Idea

Scientific Method

Every day, no matter where you are, you will see people using their cell phones. People use their cell phones for more than just making calls though. They use them for texting and searching the Internet, too. But some health groups are concerned that using your cell phone too much can be hazardous to your health as it exposes your body to electromagnetic radiation. In this electricity and electronics science project, you will investigate how much radiation your cell phone emits when used… Read more

Smart Medicine Cabinet: Build a Sensor That Reminds Patients When to Take Medication

Science Fair Project Idea

Scientific Method

Have you ever had to take prescription medicine to get over an illness? To get better, it is important to take the medication in the proper manner and at the proper time. Wouldn't it be cool if there were a tool or piece of automated equipment that held your medicine and reminded you to take it? A tool that would know when you picked up the bottle and took your medicine? Building a smart medicine cabinet is what this science project is all about! Read more

Explore Interplanetary Spacecraft Maneuvers with FreeFlyer®

Science Fair Project Idea

Scientific Method

If you are interested in space travel and willing to do some coding, this project is for you! It uses FreeFlyer®—powerful software that allows you to simulate space travel—to explore essential mission questions. Space travel is complex. Many factors influence the trajectory of a spacecraft. Simulations like the ones generated by FreeFlyer are powerful, as they allow you to analyze each factor in isolation, and then visualize the effects in various ways. Once you familiarize… Read more

Water Striders & Surface Tension

Science Fair Project Idea

Scientific Method

Water striders (also called water bugs, pond skippers, etc.) are insects that can hop around on the surface of water (Figure 1). Unlike boats or other floating objects that are partially submerged and held up by the resulting buoyant force, water striders are held up by surface tension. Figure 1. Water striders (image credit Isaka Yoji). You can build your own water striders using thin wire (Figure 2 and summary video). Do some background research about… Read more

Use DNA Sequencing to Trace the Blue Whale's Evolutionary Tree

Science Fair Project Idea

Scientific Method

The first land animals took their tentative steps out of the ocean and onto solid ground around 365 million years ago. Over millions of years, these early ancestors developed into tetrapods, including amphibians, reptiles, dinosaurs, birds, and mammals. Then, around 50 million years ago, the reverse process occurred: the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of… Read more
