The Big Dipper is easy, and once you find that, you can find the Little Dipper too.

You have to be in the northern hemisphere to see this constellation.

When you get there, change your location to Rexburg.

Change the Time to 12:00.

Choose one constellation to follow and draw it on the proper location in the first circle.

Hint: You can zoom out to get a better look.

Change the time to

1:00

and draw the same constellation in its correct location in the

second

circle. Has it moved?

Change the time to

2:00

and draw the same constellation in its correct location in the

third

circle

. Has it moved

?

Write down your observations about how constellations move

hourly

across the sky.
