 4/29/14 “Star Charts”  Learning Target:  What are some observations visible when looking at star charts at different locations around the Earth? (similarities and differences)  Before: _____________

 Star Charts : pictures taken from Earth looking out at the stars in the local sky This star chart was taken in the northern hemisphere

 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

 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  Look at the locations of each of the constellations shown

Seattle Ursa Major Uras Minor Cygnus Cassiopeia Gemini Perseus Andromeda Pegasus Orion Cetus

LA Ursa Major Uras Minor Cygnus Cassiopeia Gemini Perseus Andromeda Pegasus Orion Cetus

Sydney Andromeda Cygnus Aquila Cetus Piscis Austrinus Sagittarius Grus Scorpius Eridanus Ara Hyrus

 In your notebook write down the locations and the major constellations you see  When you have written down each of the constellations note their locations  Finally discuss any similarities and differences between the three locations

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.
