Physics: mechanics, energy, thermodynamics, electromagnetism, optics, forms of matter and so on.
Chemistry: atomic theory, inorganic chemistry, chemical bond, reaction rate, solution, equilibrium state, electrochemistry, organic chemistry, biochemistry, nature and state of matter, etc.
Biology: cytology, botany, zoology, microbiology, ecology, genetics, life evolution, etc.
In addition, geology, meteorology, oceanography, astronomy and environmental science can all be used as background knowledge for the scientific reasoning part of the ACT test. The content of the article can be experimental statistical data and explanations of various scientific theories of a phenomenon; Students need to read a lot of related text descriptions, tables and charts.
These scientific information mainly appear in the following three forms:
Data analysis: Students are required to understand, interpret and evaluate various graphic and tabular information.
Experiment summary: Students are required to understand, analyze and explain the design of the experiment, and make a scientific evaluation of the experiment.
Theoretical comparison: Students are required to understand and evaluate two or three different scientific theories and hypotheses about a scientific phenomenon.
These contents seem to discourage many students, but you don't need extensive background knowledge to answer questions, because the problem-solving information is given in the topic meeting, and the problem-solving process itself can be competent on the basis of physical chemistry and biology in middle school.
Correct problem-solving methods and test-taking skills should be guided by how to grasp the key information of the topic, and well-known information may mislead students.
The scientific reasoning part of ACT test aims to examine students' ability to understand, analyze, investigate, reason and solve problems. This part of the score is equal to the other three parts, all of which are 36 points.
