1. April 17, 2015 Daily Question: What motion causes the seasons? How long is one revolution? Materials: Pencil Notebook/Folder IAES- p. F-32 Daily Objective: Today we will observe how Earth’s tilt leads to different surface temperatures. Agenda : Bell work Activity 77 Thank you for not chewing gum or anything else

3. THIS IS ACTUALLY A PICTURE OF LL Ori and the Orion Nebula This esthetic close-upThis esthetic close-up of cosmic clouds and stellar winds features LL Orionis, interacting with the Orion Nebula flow. Adrift in Orion's stellar nursery and still in its formative years, variable star LL Orionis produces a wind more energetic than the wind from our own middle-aged Sun. As the fast stellar wind runs into slow moving gas a shock front is formed, analogous to the bow wave of a boat moving through water or a plane traveling at supersonic speed.LL OrionisOrion Nebulastellar nurseryLL Orionisthe windbow wavesupersonic

6. 1.Quietly read Activity 77 which starts on page F-32 in the book. 2.Write down any questions you may have about today’s activity. 3.Make sure you know what kind of data you need to record from the solar cell.

7. Data Table Activity 77 You need to make a data table to record the results for your experiment. When you do your testing, you need to test the solar cell in the following positions:  45 degree angle to Sun  90 degree angle to Sun  Facing directly toward the Sun  Facing away from the Sun  Completely blocked from any sunlight (be sure to indicate how you blocked the sunlight from the cell)
