Are the stars spinning, or is it just you? Discover how the spinning Earth changes the way we see stars. If you’re a stargazer (or an aspiring one), this science fair project will help you create a star clock that uses the stars to determine what time it is on earth!
- Two 8 ½ x 11” sheets of cardstock paper that can go through a printer
- Paper fastener
- Print this two-page worksheet on your cardstock paper. Cut out the white disk and the black disk. Attach them in the center with a paper fastener or brad. This central point represents the North Star, Polaris.
- Choose a clear night, and find the North Star in the sky. Face the North Star. Move the lighter circle so that you have the current month at the top.
- Now, look for the Big Dipper. It should look like a big ladle in the sky. Move the smaller, darker circle around until it lines up with the positions of the big dipper’s stars.
- What time do you see highlighted in the gap in the black circle? Check your watch. This should be close to the current time. If you are on daylight savings time, you will need to add one hour to the time. Did your star clock work? How well did it work?
You will be able to tell the time by moving the star clock around to the current month and lining it up with the stars in the sky.
