Correlation of Coronal Mass Ejections with the Solar Sunspot Cycle

Science Fair Project Idea

Scientific Method

Scientists have known for hundreds of years that sunspot activity waxes and wanes over a cycle that lasts approximately 11 years. In the 1970's, scientists discovered that the sun periodically blasts electrified gases into space, in huge outbursts called 'coronal mass ejections,' or CMEs. This project asks the question: do CMEs follow the solar sunspot cycle? Read more

Detecting Exoplanets Using Transit Photometry—Advanced

Science Fair Project Idea

Scientific Method

In astronomy, a transit (or astronomical transit) is a phenomenon when a celestial body passes directly between a larger body and the observer. As viewed from a particular vantage point, the transiting body appears to move across the face of the larger body, covering a small portion of it. The word "transit" refers to cases where the nearer object appears smaller than the more distant object. Cases where the nearer object appears larger and completely hides the more distant object are known as… Read more

How Far Away Is the Moon?

Science Fair Project Idea

Scientific Method

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

How Soon After Sunset Does the Sky Become Dark?

Science Fair Project Idea

Scientific Method

Here's an astronomy project idea from Dr. James Pierce, a professor in the Astronomy Program at Minnesota State University, Mankato: "Determine the length of twilight at different times of the year by observing the time at which certain bright stars first appear and comparing with the sunset time. Beware of variations due to stars appearing at different altitudes. Try using Polaris as a standard. Also note the time at which automatic streetlights turn on. Determine how soon after sunset stars… Read more

Can you count the stars in the night sky? People who live in rural areas can see many more stars than those who live in cities. We're all looking up at the same sky— why can some people see more stars than others? Try this activity to find out! Read more

Similar Triangles: Using Parallax to Measure Distance

Science Fair Project Idea

Scientific Method

Want to stretch your imagination? One good way is to try to imagine how far it is to a distant star. How much farther away is it than the moon is from the earth? How much farther away than the earth is from the sun? How long would it take to get there? In this project, you'll learn one way of measuring the distance without leaving Earth. Read more

Do you enjoy going stargazing on a warm night? Summer can be a great time to watch the stars as well as other celestial events, like the Perseids, which is an impressive meteor shower that happens each year from mid-July to late August. Did you know that ancient astronomers could actually measure the distance from Earth to faraway stars? How could they do this without modern technologies? In this activity you will find out by exploring the relationship between the distance of an object and the… Read more

Using the Solar & Heliospheric Observatory Satellite (SOHO) to Determine the Rotation of the Sun

Science Fair Project Idea

Scientific Method

Here's a cool project that shows you how to use images from an orbiting observatory to measure how fast the Sun rotates. Read more

Why Does the Moon Appear Larger at Some Times?

Science Fair Project Idea

Scientific Method

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
