Science Fair Project Idea
You are coming into the house after a game of flashlight tag with your friends, but the front porch light is not on for you to see the doorknob! What is going on? Maybe your parents know that turning a light on means moths will gather there, and they do not want you letting moths inside when you open the door. You have probably noticed how moths are attracted to lights at night. They will even fly dangerously close to flames in their journey toward light. In this project, you will learn a… Read more

Would it surprise you to learn that no one knows the exact age of the universe? Astronomers have estimates, and as they gather increasingly precise data and measurements, they continue to refine those estimates to come up with more accurate estimates. In this project, you can look at data about stars in dense groups called globular clusters and come up with your own estimate for the minimum age of the universe. How closely will your estimate match those of other astronomers? Read more

Do you like to look up into the night sky? There are so many stars, it can be mind boggling! Some ancient people marked time by the changes in star patterns. We still use changes in constellation patterns to mark astronomical time. Do constellations change more in one hour, one day, one month, or one year? Read more

Can you imagine designing and building a space telescope the size of a tennis court? Believe it or not, that is someone's job! Engineers are hard at work on the James Webb Space Telescope, or JWST. This telescope has the potential to enable astronomers to see light from when the Universe was first formed. No one knows what amazing discoveries this might lead to. However, to make the telescope work properly, engineers have to overcome a lot of challenges. In this science project, you can… Read more

Science Fair Project Idea
Imagine seeing waves glowing a beautiful blue color. The marine dinoflagellate Pyrocystis lunula is responsible for this magnificent phenomenon. Pyrocystis lunula is a bioluminescent organism—bioluminescence is the production of light by living organisms. But does this organism always glow, no matter what the conditions, such as how much light there is? In this biotechnology science fair project, you will investigate how altering this dinoflagellate's exposure to light and dark affects… Read more

Comets—big lumps of rock, ice, and frozen gases that orbit the Sun—are among the most amazing heavenly objects seen in the night sky. The glowing tail behind the comet's nucleus inspires wonder. But did you know that a comet's tail is evidence that it's melting? As a comet passes by the Sun on its orbital path, it starts to melt. But do bigger comets melt faster than smaller comets? In this astronomy science project, you will investigate how the size of the comet affects the… Read more

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches! Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements… Read more

You know how to make new colors by mixing paint or crayons. For example, you get green by mixing yellow and blue, or orange by mixing red and yellow. With paint, blue, yellow, and red are primary colors, which you can use to make other colors. Have you ever tried making colors with light? Are the primary colors the same ones you use for paint? Do this experiment and find out. Read more

Do you think worms are gross? Or that they are only good for birds or fish to eat? Well, in this zoology science project, you will find out that this lowly animal helps to put food on your table, too, by all the hard work that it does in the dirt. In this science project, you will discover in what kind of soil it likes to do its work. It is wiggly good fun! Read more

Have you ever wanted to analyze data from a NASA spacecraft? In this science project you will use data from NASA's MESSENGER mission to measure the diameter and calculate the depth of impact craters on Mercury. You will then analyze that data for relationships between a crater's depth and diameter. This is your chance to perform a science project as a NASA researcher would! Read more
