I posted a question on Ask a Scientist. I wanted to know what causes normal cells to turn cancerous. I did not receive an to my question so I have gone on a quest of my own. Some great links I found to answer this question are;

http://www.sciencemuseum.org.uk/WhoAmI/FindOutMore/Yourbody/Whatiscancer/Whathappensincancer/Howdohealthycellsbecomecancerous.aspx
http://cancerhelp.cancerresearchuk.org/about-cancer/what-is-cancer/cells/how-cancer-starts
I new insight I gained was that cancer cells do not develop over night. I also discovered that turning a healthy cell into a cancerous cell, is not a quick and easy process. Something that I found very interesting was that most precancerous cells die before they can cause cancer. This information was interesting and helpful. I still have more questions about cancer cells, but I will save that for another day.
Enjoy the links.

Presentation Tool Evaluation
Prezi
The Prezi tutorials were very informative. I would recommend watching these prior to getting started. It takes a little getting used to but if you spend a little time with it, you will learn how to develop a great presentation. The special features of Prezi allow you to layer objects and link objects together. As far as reliability I think it would be a great tool to use in the classroom for content presentations. Prezi is available online and it is free. The Prezi website provides you with examples that you can view to get ideas for your own Prezi presentation. You can upgrade your subscription to improved versions, but the free subscription is all you need to get started. It is accessible form home, and at school in the classroom. Prezi allows you to add animation sound and video clips to your presentation. I think that Prezi would be engaging and motivational for students. It is a great way to collaborate with other educators.
Wiki
I like the idea of using Wiki to communicate with other educators. Wiki allows you the opportunity to work collaboratively with others using the same document. It makes collaborating quick and easy because several different people at different locations can edit and add new information to the same document. There are free tutorials on line as well as free subscriptions.
