Marie Curie was a Polish-born French physicist, known for her of radioactive chemicals. She was born in Warsaw, Poland in 1867, the youngest of five children in her family. Growing up, Curie was smart and , and dreamed of getting a university degree. However, the University of Warsaw only admitted male students at the time. In order to get her degree, Curie moved to Paris. She studied physics at Sorbonne University, and later received another degree in math. After her , Curie went on to become a scientist. While working with a mineral known as pitchblende, Curie discovered a new chemical property, which we now know as radioactivity. She also discovered two new elements, which she called polonium and radium. Because of these scientific discoveries, Curie became the first person to ever win two Nobel Prizes. Curie died in 1934 from an caused by her exposure to radiation. However, her research has helped modern develop treatments for cancer, and she is still seen as one of the greatest scientists of all time.

Comprehension questions

1. Marie Curie was born in

Correct! Wrong!

Marie Curie was born in Warsaw, Poland.

2. Curie moved to Paris for her degree because

Correct! Wrong!

Curie moved to Paris for her degree because the University of Warsaw only admitted male students.

3. Curie was the first person to

Correct! Wrong!

Discussion/essay questions

  1. While Marie Curie’s research did help scientists develop cancer treatments, her research was also important for the invention of the atomic bomb during World War II. The atomic bomb is still a controversial subject because of the amount of deaths it caused. Do you think Curie’s discoveries had a positive impact on the world, or a negative one?

The Big Bang theory is a theory scientists use to the creation of the universe. The theory states that all of the matter in the universe began to expand from one single point. This idea was first proposed by astronomer Georges Lemaître in 1927. He received evidence to support his theory when another astronomer named Edwin Hubble observed that seemed to be moving away from each other. This was an indication that the universe was expanding. Because of this new information, Lemaître concluded that the universe must have once been smaller and denser. According to the theory, the universe began as something known as a singularity, which is an where matter is infinitely dense. Over 13 billion years ago, this singularity began to expand, and the matter inside it formed atoms that would later form stars and planets. Lemaître’s idea received a lot of criticism, because most scientists at the time believed that the universe had existed . However, throughout the 20th century, scientists continued to find proof that Lemaître’s theory was accurate. Today, the Big Bang theory is the most widely accepted explanation for how the universe was .

Comprehension questions

1. The idea of the Big Bang was first proposed by

Correct! Wrong!

The idea of the Big Bang was first proposed by Georges Lemaître.

2. Edwin Hubble made the observation that

Correct! Wrong!

Edwin Hubble made the observation that galaxies were moving away from each other.

3. Lemaître's idea received criticism because

Correct! Wrong!

Lemaître's idea received criticism because most scientists believed that the universe had existed forever.

Discussion/essay questions

  1. While most scientists today agree that the universe was created by a Big Bang, some have other theories. Do you believe that the Big Bang theory is the correct explanation? Why or why not?

Albert Einstein was one of the most influential of the 20th century. He was born in Germany in 1879, and began attending school in 1885. As Einstein got older, he became fascinated with the nature of . He published his first scientific paper at the age of 16, and later went on to study at a university in Switzerland. In 1905, Einstein published four scientific papers. The papers introduced his theory of special relativity, which allowed scientists to better understand the between time and space. Einstein won the Nobel Prize in 1921 for his achievements. In the 1930s, however, Einstein became a target of the Nazi Party of Germany. He moved to the U.S. to protect himself, and continued to work as a physicist. Einstein died in 1955, but his brain is kept in the Princeton University Medical Center, and it is still by scientists today.

Albert Einstein was one of the most influential scientists of the 20th century. He was born in Germany in 1879, and he began attending school in 1885. As Einstein got older, he became fascinated with the nature of light. He wrote his first scientific paper at the age of 16, and later went on to study physics at a university in Switzerland. In 1905, Einstein published four scientific papers. The papers introduced his theory of special relativity, which allowed scientists to better understand the connection between time and space. Einstein won the Nobel Prize in 1921 for his achievements. In the 1930s, however, Einstein became a target of the Nazi Party of Germany. He moved to the U.S. to protect himself, and continued to work as a physicist. Einstein died in 1955, but his brain is still kept in the Princeton University Medical Center.
