The hypothesis is that the atmosphere between the star and the observer's eye causes starlight to twinkle.

You will count star blink rates higher in the sky compared to stars lower in the sky, on a windy night compared to a still night, and at sea level compared to on a mountain top. You will also record the color of the star when it twinkles each time.

You will need a clear night, a telescope or binoculars, a notebook, and a pen or pencil.

Through this project, you'll learn that the atmosphere between the star and the observer's eye causes starlight to twinkle. You'll also observe that the steadiness of images, or "seeing," is best when the twinkling is least.

This science project is unique because it allows you to explore the atmosphere and how it affects starlight. You'll also learn how astronomers use twinkling to collect data about stars and galaxies.

Experiment variations to consider include counting star blink rates on a cloudy night compared to a clear night, and at different times of the day.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
