Constellations :: An Out-of-This-World Science Fair Project

Stars are so much more than pretty lights in the night sky. They act as both a compass and a clock. For hundreds of years people have relied on the stars to navigate the ocean and to know when to plant their crops or perform religious ceremonies. To make the stars easier to read, these people grouped the brighter stars in to recognizable patterns—constellations.

If you were to play connect-the-dots with the constellations, they would each resemble a different object. For example, the constellation Draco looks like a dragon with a small, pointed head and a long, curving body. Perhaps the most famous and distinguishable constellations are the Ursa Major and Ursa Minor, better known as the big and little dippers. Depending on the time of year, the constellations will appear in different positions in the night sky.

Step 1: Create a Hypothesis

The purpose of this science fair experiment is to determine if it’s possible to make two models of the Northern Hemisphere’s night sky, one of the Spring sky and one of the Fall.

Step 2: Gather Your Materials

For this project, you’ll need the following:

  • Black poster paper
  • Luminous white paint
  • Tracing paper
  • Ice pick
  • Glue
  • Scissors
  • A star chart

Step 3: Follow the Procedure

  1. First, search the internet or an astronomy book for two maps of the Northern Hemisphere’s night sky, one of the Spring sky and one of the Fall sky. Then trace the constellations onto tracing paper.
  2. Cut your poster paper into 28 wedge-shaped segments, each exactly the same size.
  3. Glue 14 of the segments together so that the points meet at the center creating a circular pattern. You’ll need to cut small incisions into the sides of each wedge so that they can interlock and glue together properly. Repeat this with the other 14 segments.
  4. Place your tracing paper in the center of wedges. Use your ice pick to punch holes through your tracing paper and poster paper. You are creating the stars. Using your luminous white paint, connect the lines of each constellation.
  5. Fold another piece of poster paper into a circular tunnel about 12 inches wide. Fold down the ends of your wedges and glue them to one end of the tunnel, creating a dome. When you’re finished you should be able to hold the dome up to the light and see the small holes glowing like stars in the night sky.

Step 4: Gather Your Results

Once you have successfully created both domes, you can conclude that it is possible to create your own replica of the night sky. In a dark room, you’ll see the luminous paint outlining the constellations, and in a bright room, you’ll see the stars themselves. (If your teacher requires a graph, create of bar graph showing the number of stars found in each constellation you used in the experiment.)

Throwing your gorgeous face into the mix would only make it even worse.

So do people judge you by your profile picture because you have a bad personality or because they disregard your great personality and assume you're a bad person because you support Trump? Definitely the second.  Meaning your initial statement isn't entirely correct. There are indeed people who will or will not want to befriend you for your personality instead of for whatever your picture is, yes. But if someone doesn't know much about you as a person or is just too ignorant to care about your personality, then they're gonna judge you solely by that picture. You're genuinely one of the very last people I'd have thought would ever make such a weak point and contradict themselves like that, bud. And you are the last person I'd have thought would come up with such an interesting dilemma. Good work. I wasn't making a serious statement. I was referring to how my boundless charisma is enough for people to want to know me, without having to resort to my dashing good looks.
