  1. 1. Warm-up, 12.01.2009<br />What is magnetism? What are some machines that require magnets in order to function?<br />
  2. 2. Assignment, due Friday: Cool Science Stuff, Part 2<br />Bring in an article, picture, book, video, or song about a topic in science that is interesting or exciting.<br />Brief (1-2 minute) presentation = 2 grades.<br />Power point or poster-board presentation = 4 grades.<br />Group presentation (3 people max) with Powerpoint and multimedia (music/video) = 6 grades.<br />Group presentation with powerpoint, multimedia, in-class demonstration/experiment = 8 grades.<br />
  3. 3. Chapter 14 Scavenger Hunt<br />Get into a group of three. (No, you can’t have more than three. Yes, you can work on your own.)<br />Get a book (Physical Science).<br />First team to find all of the missing words gets a prize.<br />All of the answers are found in chapter 14 (p. 422-449).<br />You may start when I change the slide.<br />
  4. 4. 1) A light display that occurs when charged particles from the sun are captured by Earth’s magnetic field.<br />2) MRI stands for “________.”<br />3) DC (direct current) flows only in _____ through a wire.<br />4) Alternating current (AC) ________ in a regular pattern.<br />5) A transformer does this to the voltage of an AC.<br />6) The force between two magnets depends on this.<br />7) A magnet is surrounded by this.<br />8) The group of atoms with aligned magnetic poles is called the ____.<br />9) Three metals that are attracted by magnets are _____, 10) _____, and 11)_____.<br />12) Magnets are surrounded by a _____. This is strongest at the regions called 13) ______.<br />14) A small magnet that is used to determine north and south (directions).<br />15) A magnet that is broken in half will have this many poles.<br />16) The name of the Danish physics teacher who found that electricity and magnetism are related.<br />17) A wire wrapped into a cylindrical wire coil is called this.<br />18) As the current moving through a wire increases, the strength of its magnetic field ____.<br />19) A moving electron charge is surrounded by a ____.<br />20) An electromagnet is a (Choose one: temporary/permanent) magnet.<br />21) In a simple motor, a(n) _________ rotates between the poles of a (n)22) _________.<br />23) In order to create an electromagnet, you need three things: ______, 24) _______ and 25)_____.<br />26) A gauge that measures electric current.<br />27) An electrical current is produced by ________ or 28) _________.<br />29) An MRI is used to take this kind of picture.<br />A generator produces an electric current how?<br />Create a foldable as seen on page 423 with at least 3 items in each column.<br />
