==Concept #==
X-rays are part of the electomagnetic spectrum. They were discovered by Roentgen.
Please click [http://en.wikipedia.org/wiki/Wilhelm_Röntgen here] for more information.
The following is a picture from the first medical X-ray. <br>

*'''Evaluation'''
As students read about these scientists, ask them to think about the following questions:<br>
What important discovery was made by Wilhelm Roentgen?<br>
What material did Antoine Becquerel work with in his own investigations of X rays?<br>
What did Becquerel discover through his experiments?<br>
What two elements were discovered by Marie and Pierre Curie?<br>
Why is Ernest Rutherford considered the father of nuclear physics? List Rutherford's major achievements.<br>
