Starting a Blog is easy.  One site which a teacher could use is Blogger.com.  This is an excellent site which is part of the Google.com network.  A teacher or student can create an blog account.  There are several options on the design of the blog page.
Once signed in the teacher chooses to compose the new blog page.   The teacher can customize the layout, the background images, and placement of information on the web page.  Since Blogger. com is pat of the google.com network.  It is easy to access to YouTube videos, google images, GMail.com, google earth, and other google tools.  All of these tools can be used in order to make an interesting and creative blog or page.



For example the my page on Martin Luther King Jr. provides a photo of King, as well as a documentary video on the Selma to Montgomery March.  I can also post speeches and more information on King as I teach the unit.  The other great thing is I can continue to add or delete information to modify the unit every year.
