How do you make a model of a star constellation?

The first part will be to conduct research using free online software to establish a database of the major stars in a chosen constellation. In the second part, students will draw a map of the constellation, then use the coordinates of the stars to create an accurate three dimensional model in a box.

What stars or constellations can I supply?

You can supply some stars or constellations if they are unfamiliar, such as Betelgeuse, Sirius, Bellatrix, Regulus, or Alpha Centauri for stars and Orion, Draco, and Scorpio for constellations.

How do you find the major stars in a constellation?

1. identify the major stars in chosen constellations including the meaning of their names, their spectral types, and their coordinates; 2. build an accurate scale model of their constellation showing the major stars in their correct positions (distances, right ascension, and declination) and spectral types (OBAFGKM);

How many constellations do astronomers recognize today?

Some asterisms, such as the Summer Triangle, cross over several constellations. The Big Dipper is an asterism contained inside the constellation of Ursa Majoris. Explain that modern astronomers recognize 88 constellations, some larger than others. Point out that the Black family in the Harry Potter series are named after stars and constellations.

Why are the constellations that we see not really permanent?

Why are the constellations that we see not really permanent? (Stars do move through space in their own directions. Over tens of thousands of years, the constellations will distort and become unrecognizable. Our Sun is also moving through space and carrying the Earth with it, so that over time we will leave our local stars behind. )

How do constellations distort?

The constellations are merely the positions of the stars as we see them from Earth, but as our Sun travels through space, or ifwe could travel through space, we would see the constellations distort as the closer stars appeared to move more than the distant stars.

What does B mean in Star Data Table?

B – Thoroughness of their Star Data Table, to include stellar types, coordinates, names and their meanings, alternative names, and constellation mythology.

What grade is the parallax lesson?

This lesson is designed for 6th grade students up to about tenth grade but can be modified and extended for higher division or advanced students. One follow-up would be to teach students the parallax lesson linked above to learn more about measuring stellar distances. Advanced students could add more to their Star Tables, such as including Deep Sky Objects such as galaxies and nebulas using the Messier and NGC catalogs. These could be added to their maps before taping them into the box.

How to keep eyepiece from moving?

To provide an eyepiece of sorts, use a small canning jar lid and tie it in place hanging in the opening at the front of the box, securing it with the black string to the top and both sides of the box to prevent the eyepiece from swaying or moving. Keep the eyepiece as close to the front of the box as possible while still keeping it secure.

How far is Betelgeuse from the eyepiece?

So Betelgeuse, with a distance of 427 light years, will be 7.1 cm from the eyepiece knot. To hang the stars, look through the center of the eyepiece to the star you want to hang and visualize a line going vertically up from that star to the top of the box.

How to identify the major stars in a constellation?

1. identify the major stars in chosen constellations including the meaning of their names, their spectral types, and their coordinates; 2. build an accurate scale model of their constellation showing the major stars in their correct positions (distances, right ascension, and declination) and spectral types (OBAFGKM);
