Objectives
(OBJECTIVES will be listed near the beginning of each day’s slideshow. I want
you to know these or be able to do these for exams. If the following are not
covered in class, look them up in a text, in the notes and/or on the web. One
good study technique is to make flashcards for these.)
• Define moon, planet, star, solar system, galaxy and universe. (Look these up
in your text or online, then make and study a flashcard for each.)
• List the 3 hallmarks of science. Distinguish science from non-science. (flash
cards good here too.)
• Learn and practice some of the study tips (see: Success in this course) in
the syllabus. (for example, make flash cards)
• Start to develop a “feel” for the contents, size and layout of the solar system
and universe.
• Locate the class website, today’s slideshow & today’s homework at the end
of this slideshow.

the today’s notes.
