ACT Science Content

Although many people claim that the ACT Science test does not require any background knowledge, they are incorrect.  If you examine several ACT tests, you will find that you must have basic knowledge from these two high school courses:

  • Physical Science
  • Biology

They require you to have this background knowledge because high school juniors across the country should have taken these two courses, no matter the rigor of their individual high schools.  Expect to see just a handful of questions that involve actual background knowledge from these two areas.

If you have taken advanced science, such as AP Chemistry or AP Physics, that certainly won’t hurt you.  It will help in the sense that your general ability to reason through scientific charts and graphs will be stronger, not because you need to have specific knowledge from any of those areas.

The material they present on the passages can come from all sorts of general scientific areas:  physics, chemistry, biology, botany, zoology, astronomy, geology, and so forth.

The ACT Science Section has 3 types of passages:

  • Data Representation (38%). There are three of this type of passage, and each passage has 5 questions.  You will need to evaluate information presented in graphs, tables and figures.
  • Research Summaries (45%). There are three of this type of passage, and each passage has 6 questions.  You will need to analyze 2 or more experimental summaries, thinking about the results and the experimental design.
  • Conflicting Viewpoints (17%). You will only have 1 passage of this type, and it has seven questions.  It will present viewpoints from anywhere from 2 up to several scientists.  You will need to read a good bit here, although sometimes there is a graph or two given as well.  You will need to sharpen your ability to compare and contrast differing scientific explanations.

The passages are in a random order of difficulty, so just be on your toes to think critically at any point.
