Science 90 - Jan 9

Today we finished our notes yesterday on other objects of our solar system.  We learned what asteroids were as well as meteors and comets.  Students were then assigned the assignment on slide 35.  This one is slightly different than the one in your notes.  Do questions 1-3, 10-13 on page 340.  After this we then started to learn about the properties and life cycles of stars.  Many new words were introduced.  Wwe also learned about the life cycles of different types of common stars, from red dwarf stars that use their fuel very slowly to massive supergiant stars that use their fuel much quicker.  We learned what happens to supergiant stars at the ends of their lives, a violent explosion called a supernova.  We stopped at this point and will continue on from here on Monday, to learn about the aftermath of these explosion, things called neutron stars and black holes.  The slides we covered today were slides 33 to 50.  Have a great weekend everyone.
