Scientist Match worksheet: Match each scientist to their science contribution.

Task: Match each scientist to their science contribution.

#### Scientists:
1. Galileo Galilei (1564-1642)
2. Thomas Edison (1791-1867)
3. Albert Einstein (1879-1955)
4. Isaac Newton (1642-1727)
5. Marie Curie (1867-1943)
6. Niels Bohr (1885-1962)
7. Benjamin Franklin (1706-1790)

#### Contributions:
A. Developed the theory of universal gravitation; how the force that pulls two objects together depends on the mass of each object. Applied this theory to the planets' places in the universe.
B. Studied the structure of atoms and introduced the model that atoms have a positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, similar to our solar system.
C. An inventor with over 1,000 patents, this scientist is responsible for many of the modern items we use every day, among which are the phonograph, the incandescent lightbulb, motion pictures, and the alkaline battery.
D. A politician and civic activist, this scientist and inventor is well-known for work with electricity and inventions such as the lightning rod, bifocals, and odometer.
E. Provided evidence for Copernicus’ theory that the Sun is fixed in the center of our universe and the Earth and other planets revolve around the Sun.
F. A physicist and mathematical genius, this scientist is best known for the theory of relativity (all motion is relative) and the equation that proves such: E=mc².
G. The first person to be awarded two Nobel Prizes, this scientist discovered the elements Radium and Polonium, and created the theory of radioactivity.

Solution:

1. Galileo Galilei:
- Contribution: E
- Explanation: Galileo provided evidence for Copernicus’ heliocentric theory by observing the moons of Jupiter and the phases of Venus, which supported the idea that the Earth and other planets revolve around the Sun.

2. Thomas Edison:
- Contribution: C
- Explanation: Thomas Edison was a prolific inventor with over 1,000 patents, including the phonograph, incandescent lightbulb, motion pictures, and the alkaline battery.

3. Albert Einstein:
- Contribution: F
- Explanation: Albert Einstein is best known for his theory of relativity and the famous equation \( E = mc^2 \), which describes the relationship between energy and mass.

4. Isaac Newton:
- Contribution: A
- Explanation: Isaac Newton developed the theory of universal gravitation, which explains the force that attracts two objects based on their masses and the distance between them. He also applied this theory to explain the motion of planets.

5. Marie Curie:
- Contribution: G
- Explanation: Marie Curie was the first person to be awarded two Nobel Prizes. She discovered the elements radium and polonium and made significant contributions to the theory of radioactivity.

6. Niels Bohr:
- Contribution: B
- Explanation: Niels Bohr introduced the atomic model where electrons orbit a positively charged nucleus, similar to planets orbiting the Sun. This model revolutionized our understanding of atomic structure.

7. Benjamin Franklin:
- Contribution: D
- Explanation: Benjamin Franklin was a polymath who contributed significantly to science, politics, and invention. He is well-known for his experiments with electricity (e.g., the lightning rod) and inventions like bifocals and the odometer.
