Open the “ClassAction” package of astronomy interactives. (To download and install these interactive packages, please go to the this page)
Under “Animations” on the bottom left, click on “Big Dipper 3D”.
Drag around the screen with your mouse.
The pattern of stars shown in the interactive tool is called the “Big Dipper”. The big dipper is an asterism, which is an informal grouping of stars that resemble a shape, as opposed to an official grouping of stars that is called a constellation. However, for this exercise, you can consider asterisms and constellations to have the same properties.
You may have already noticed the Big Dipper in the night sky if you ever looked North on a clear night. If you haven’t, I suggest you try to find it during the next clear night. Do you notice the plough-like shape of the Big Dipper?
Flag question: Question 1
Question 12 pts
The stars that make up the Big Dipper appear close to each other when we look up at the night sky. However, are the stars that make up the Big Dipper actually physically clustered around the same region of space? Explain in your own words (just a few sentences) why the stars appear to be close to each other when in reality they might not actually be close to each other.

Flag question: Question 2
Question 22 pts
The Big Dipper appears somewhat like a plow when viewed from the Earth. Imagine you are an alien who lives on another planet orbiting a different star in our Galaxy. If you looked up at the night sky at the same set of stars that make up the Big Dipper, would the shape still necessarily look like a plough? Why or why not? Explain your answer in a few sentences.
