Science Fair Project Idea
Some claim the Moon appears larger when near the horizon. Make a series of observations of the Moon, measuring the Moon's angular diameter each time. You should also note the Moon's altitude above the horizon, and the Moon's phase. You should do background research on the lunar orbit to determine the necessary time period. Do you find predictable variations in the Moon's diameter? Can you relate this to the Moon's changing distance from Earth? From your data, try to determine when apogee and… Read more

thumbnail The Milky Way is the edgewise view of our home galaxy, a disk made up of billions of stars. The Sun resides on one of the spiral arms of the disk, 30,000 light-years from the thick hub of the galaxy. The actual center, with a black hole 3-4 million times the Sun's mass, is hidden by dust clouds in space. In this astronomy science fair project, you will use astronomical data to locate the center of this galaxy. Read more

Science Fair Project Idea
thumbnail This is a great project for someone that is interested in both stargazing and photography. Bright city lights and even the light of the full moon obscure the dimmest stars, which can make identifying constellations more difficult. This project shows you a way to measure the amount of background light (skyglow) in the night sky. It can be a great way for you to quickly compare the star viewing quality for different locations, or for the same location at different times of the year. Read more

Time Required Long (2-4 weeks)
Prerequisites You'll need a digital camera that take pictures in manual mode with exposure times of up to 15 seconds. You will need to know how to change the shutter speed, lens aperture, and ISO setting. A tripod for the camera is nice to have, but not absolutely essential. You will also need a computer.

Science Fair Project Idea
A fractal is, "a rough or fragmented geometric shape that can be subdivided in parts, each of which is (at least approximately) a reduced/size copy of the whole" (Mandelbrot, 1982). There are many different fractal patterns, each with unique properties and typically named after the mathematician who discovered it. A fractal increases in complexity as it is generated through repeated sets of numbers called iterations. There are many interesting projects exploring fractal geometry that go beyond… Read more

Let's suppose you can take advantage of the Internet and get a 'pen pal' located a 1000 miles away in another city. On the same night, and at EXACTLY the same time 'Universal Time', make a CAREFUL observation of where the Moon is located with respect to the background stars. You should be able to discern a slight (about 1/2 the Moon's diameter) shift in position due to parallax. Then, with a little geometry, you could estimate the distance of the Moon during the full lunar cycle (Odenwald,… Read more

thumbnail Have you ever looked up at the stars at night and wondered how fast they were moving or how far away they were? By studying how the brightness of a star changes with distance, you can answer those questions. In this astronomy science project, you'll create a model of starlight and use a light meter to discover the key relationship between brightness and distance. Read more

Science Fair Project Idea
In the U.S., lighting homes and businesses accounts for 22% of all electric power consumption (Raloff, 2006). That's $55 billion worth of electricity, or the output of 100 large power plants (Raloff, 2006). How much energy could be saved by switching home lighting from incandescent to more efficient fluorescent lights? Conduct a survey to find out what types of lighting are used in homes in your area. Come up with an estimate of how many light fixtures are used in an average home, what types… Read more

thumbnail Have you ever seen amazing, colored images of objects in space, like stars or even entire galaxies? Some of these images were originally taken with forms of radiation that the human eye cannot actually see, like x-rays. In order to create the beautiful pictures you see in the news or online, scientists have to use an image-editing program to add color to them. In this astronomy science project, you will use raw x-ray data from NASA's Chandra X-ray Observatory telescope to create amazing… Read more
