Tip of the Week -- Science

Marie Curie (1867-1934) was a pioneer in the field of radioactivity. She did not actually discover radioactivity, but she did give it the name, and she created the theory of radioactivity. She also developed techniques for isolating radioactive isotopes, and she discovered two elements, polonium and radium.

Marie was the first scientist to explore oncology. Today, when we hear of people undergoing radiation treatments for cancer, we can thank Marie Curie. The Marie Sklodowska-Curie Institute of Oncology in Warsaw, Poland, grew out of the Radium Institute, which Marie founded in 1932.

Although Marie was Polish, she was the first female professor at the University of Paris. Her husband, Pierre, was also a professor and a scientist. Together, they won the Nobel Prize in Physics in 1903. Their daughter, Irene, carried on the family tradition, winning a Nobel Prize in Chemistry in 1935. Irene's children are prominent scientists as well.

Marie also won the Nobel Prize in Chemistry in 1911. She was the first person ever to be awarded two Nobel Prizes.

Science Tip of the Week -- States of Matter

All matter has three states: solids, liquids, and gases.


If we take a look at H2O, for example. In its solid form, we call it ice. In its liquid form, it is water. In it's gaseous form, it is steam.






The freezing point of H2O is 32 degrees Fahrenheit. This is the point at which it turns from a liquid (water) to a solid (ice).









The boiling point, or the point at which it turns from a liquid (water) to a gas (steam), is 212 degrees Fahrenheit.









H2O is in it's liquid form at between 32 and 212 degrees F.









Think about these things the next time you reach for the ice cubes, drink a glass of water, or boil water on the stove.
