  • Description: An astronomer is a scientist who studies planets, stars and galaxies.  A few of their duties could include: planning a voyage to the moon or another planet, determining the composition of a planet, its atmosphere and its moons, study how galaxies are formed as well as spot comets and asteroids with potential to impact Earth.
  • Profile: William K. Hartmann (1939) proposed that most widely accepted theory on the formation of the moon: after a collision with a large body, debris from the Earth condensed to form the moon.


  • Description: A biologist studies living organisms and their relationship to the environment. Duties can include analyzing different types of taste bud receptors to understand how the tongue detects different flavors, uncover the relationship between a protein’s genetic mutations and a patient’s symptoms to better understand a disease, protect gorillas from extinction by studying their habitats and interactions in the wild, and investigate all the physiological side effects that a flight into space has on a human being’s body.
  • Profile: Jeff Corwin (1967- ) from Massachusetts is an active conservationist and wildlife biologist. He is involved with recovery efforts relating to the oil spill disaster in the Gulf of Mexico in 2010.



  • Description: A chemist is a scientist who studies the composition of matter and its properties such as density and acidity. A few of their duties could include: developing a synthetic fiber that can stop a speeding bullet, help discover new medicines that alleviate pain or cure diseases as well as discover new processes that could solve the world’s energy crises.


Civil Engineer

  • Description: A civil engineer deals with the design, construction, and maintenance of the physical and naturally built environment. Duties include designing a building that can survive major earthquake, build a dam to provide a source of power, design water-treatment facilities to reduce water pollution, and design a bridge.
  • Profile: Frederick William Cappelen (1857-1921) was responsible for designing various  buildings and bridges in Minneapolis including the Prospect Park Water Tower and the Cappelen Memorial Bridge. 



  • Description: A geologist is a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes and history that has shaped it. Geologist’s combine chemistry, physics and biology to put together the story of how the Earth came to be. 



  • Description: A meteorologist is a scientist who studies the Earth’s atmosphere. A few duties include monitoring a drought so states can make mitigation plans, chase a tornado and gather data to better understand how and why they form, track a hurricane to alert people about its path, and develop a TV weather forecast. 



  • Description: An oceanographer is another science field which combines biology, chemistry, geology and physics. Duties include studying marine life and ecosystems, ocean circulation, plate tectonics and the geology of the sea floor, and the chemical and physical properties of the ocean.
  • Profile: Robert Duane Ballard (1942- ) from Rhode Island, US is a former US Navy officer. He is most known for the discoveries of the wrecks of RMS Titanic, the German battleship Bismarck, and the USS Yorktown. 



  • Description: An optometrist is a health care professional concerned with the health of the eyes and related structures. A few duties of an optometrist includes monitor and treat eye infections, help prevent blindness by checking a patient’s retinas for early signs of eye disease, make sure new glasses fit properly and conduct vision exams



  • Description: Physicians are healthcare providers in medicine and are concerned with promoting, maintaining, and restoring human health. Among their duties, physicians detect heart disease, provide medical care, surgically repair and monitor the healing of a broken bone as well as investigate why a child’s growth is not on track.
  • Profile: Charles Horace Mayo (1865-1939) from Rochester, Minnesota. Charles was the co-founder of the Mayo Clinic in Rochester. He largely contributed to the fields of cataract, thyroid and nervous system surgeries. It was appointed to the ‘American Surgical Association’ and also elected as the president of the ‘Minnesota State Medical Society’ and ‘American Medical Association.’



  • Description: A physicist is a science who studies the natural world- from subatomic particles to the largest galaxies. A few duties could include developing a clean, unlimited fusion energy, designing a laser to fix vision problems, and simulating a roller coaster ride on the computer. 
  • Profile: Stephen Hawking (1942 - ) has combined the theory of general relativity and quantum theory in order to prove that black holes emit radiation and eventually evaporate.
