act科学测试的内容包括生物，化学，物理，和地球/空间学说(例如：地质学，天文学和气象学)。这些学科的先进的知识是不要求的，但普通的知识背景和介绍性的科学课程对于回答有些问题是必须的。
测试强调科学的推理技巧，而不只是记忆科技文内容，数学能力或阅读能力。这些信息都以三种不同方式来陈述。
the content of the science test includes biology, chemistry, physics, and the earth/space sciences (for example, geology, astronomy, and meteorology). advanced knowledge in these subjects is not required, but background knowledge acquired in general, introductory science courses is needed to answer some of the questions.
the test emphasizes scientific reasoning skills over recall of scientific content, skill in mathematics, or reading ability. the scientific information is conveyed in one of three different formats:
•数据表示(38%)和科技杂志和文章一样，以图形和表格的形式来表述信息。考察学生图表阅读，分散图的解读，对表格，图表和数字形式信息的理解。
• data representation (38%). this format presents graphic and tabular material similar to that found in science journals and texts. the questions associated with this format measure skills such as graph reading, interpretation of scatter plots, and interpretation of information presented in tables, diagrams, and figures.
• 研究概述(45%)提供多个相关的试验,问题强调对于试验设计和试验结论的解读。
• research summaries (45%). this format provides deions of one or more related experiments. the questions focus on the design of experiments and the interpretation of experimental results.
• 矛盾观点(17%)以几个基于不同的前提和假设、基于不完善的数据的互不一致的观点，着重强调对不同观点的理解、分析和比较。
• conflicting viewpoints (17%). this format presents expressions of several hypotheses or views that, being based on differing premises or on incomplete data, are inconsistent with one another. the questions focus on the understanding, analysis, and comparison of alternative viewpoints or hypotheses.
act科学是通过数据表示、研究概述、矛盾观点三种方式来陈述的，希望对大家act科学的复习有所帮助。
