TASC Science

Life Science is the study of living organisms, their life processes, and how those organisms relate to each other. Test takers must be familiar with the structures and processes of these organisms from the smallest level, cellular life, to the largest level, ecosystems.
Students should also be able to discuss the importance of biological evolution and heredity. Evolution was first proposed by Charles Darwin in the late 1800s. Since then, it has been essential to the scientific understanding of how cellular life has changed over the years and to how heredity functions.
Earth Science

Earth science is the study of the physical make-up of the earth and its atmosphere. Focus on Earth’s systems, including:

  • Geology
  • Atmosphere
  • Meteorology
  • Oceanography

Space Science and Astronomy

Examine earth’s place in the universe. Consider the hierarchy of space:

  • Earth is a planet. It revolves around the sun, which is actually a star.
  • Planets are a part of a solar system. There are eight planets in our solar system.
  • Solar systems are a part of a galaxy. Our solar system is a part of the galaxy the Milky Way.
  • Galaxies are a part of a universe.

Our solar system appears to have been formed from a disk of dust and gas, which was drawn together by gravity. Space science is still being explored and is constantly changing. How does it related to the other areas of science? 
Remember to ask yourself: How does it relate to the other areas of science? Drawing connections can help you understand science, and better prepare for the subtest.
