  Marie was born on November 7, 1867 in Warsaw, Poland.

  Radioactivity- the amount of phosphorescent energy rays that an element gives off.;
 X-ray - A reading given by sending radioactive rays through an object.;
 Element- a substance that cannot be further broken down.;
- 
  
  Marie landed in Paris to attend this special school where she could choose to attend her classes and even to take tests.
- 
  
  Wilhelm Roentgen invented the X ray for medical uses and the whole was in love with them.
- 
  
  Married- 1895;
 Had Irene - 1897;
 Had Eve - 1904;

  While studying pitchblende, Marie discovered two radioactive elements - polonium and radium.
- 
  
  In order to make two huge advances in elements, Marie was probably great at math.
- 
  
  Cause: Marie and Pierre discovered and often handled radioactive elements.
 Effect: Marie and Pierre became weak and very sick, then die early
- 
  
  Marie and Pierre finally- after a few years, many tons of pitchblende, and fifty tons of water- extracted a few grains of pure radium.
- 
  
  They receive their first Nobel prize for their radioactive work.
- 
  
  Pierre is finally accepted to teach at the Sorbonne and they have another baby girl named Eve.
- 
  
  Pierre was killed in an incident. He was too weak to pull himself up after a horse ran him over and the following carriage crushed his skull.
- 
  
  Cause: Pierre dies in an accident.
 Effect: Marie takes over his former job.
- 
  
  After Pierre's death Marie won her own solo Nobel prize.
- 
  
  Marie Curie and her daughter Irene take portable "little curies" to help soldiers in WW1.
- 
  
  Marie Curie was a living - and non-living - example of the power and danger of radioactivity so that no one must suffer the same consequences.
