Star Charts

Today we will have a quick discussion and you will look at some star charts at your lab stations

At your lab stations are star charts from Portland, Oregon taken each month of the year

Note any changes you see as you look at each month’s chart

Document similarities and differences you see between each month in your notebook

Be ready to discuss your observations you will be called on at random so be sure each person has written down their observations

Look at the next three star charts

All the charts are taken at relatively the same time but are at different locations around the globe

Look carefully at each of the names of the constellations shown

Questions

1. At the very beginning when we discussed star charts I told you that the example was from the northern hemisphere. How did I know that?

2. You have seen that positions of stars change in the sky during the night and from season to season. Why do you think this occurs? You can answer in written format or draw a diagram.
