在美国ACT考试中取得高分是每一个想要去美国留学的同学们需要了解的，ACT考试是美国高考，很多同学都在为ACT的复习绞尽脑汁，那么ACT科学考什么内容?
物理：力学，能量，热力学，电磁学，光学，物质形态等等
化学：原子理论，无机化学，化学键，反应速率，溶液，均衡态，电化学，有机化学，生物化学，物质性质和状态等等。
生物学：细胞学，植物学，动物学，微生物学，生态学，基因学，生命演变过程等等 此外，地质学，气象学，海洋学，天文学，环境科学都可以成为ACT考试科学推理部分出题的背景知识。文章的内容可以是实验的统计数据，可以是对一个现象的各种科学理论的解释;学生需要阅读大量相关的文字描述，表格和图表。这些科学信息主要以以下三种形式出现：
数据分析：要求学生理解，解读和评估各种图形和表格信息
实验总结：要求学生理解，分析，对实验的设计进行解释，并对实验做出科学的评估; 理论比较：要求学生理解和评价就一个科学现象的两到三个不同的科学理论和假说。 这些内容看起来会让很多同学望而却步，不过答题并不需要广博的背景知识，因为题目会中给出了充分的解题信息，解题过程本身凭中学阶段的物理、化学、生物的基础就可以胜任。在ACT考试科学推理这部分中，取得最好的分数的人不一定是那些最了解背景的人，而是最好的理解文中信息和基于这些信息对选项做出严格判断和推理的人。正确的解题方法和应试技巧应该以如何抓住题目的关键信息为指导，而大家所熟知的信息还有可能对学生造成误导。
ACT考试科学部分介绍-ACT Science Test
Length Question Types
35 Minutes 10 Social Studies Questions
10 Natural Sciences Questions
10 Prose Fiction Questions
10 Humanities Questions
On the ACT Science Test, you'll have 35 minutes to answer 40 questions—that's about 50 seconds per question! The section contains seven passages, each followed by 5-7 questions.
You don't have to be a scientist or know the atomic number of Cadmium to succeed on the ACT Science Test. All that's required is common sense. You'll be given passages containing various kinds of scientific information—drawn from the fields of biology, chemistry, physics, geology, astronomy, and meteorology—which you'll have to understand and use as a basis for inferences.
ACT Science Question Format
Usually there are six passages that present scientific data, often based on specific experiments. Also, there's usually one passage in which two scientists state opposing views on the same issue. Each passage is followed by 5-7 questions. A warning: some passages will be very difficult to understand, but they'll usually make up for that fact by having many easy questions attached to them. The test makers do show some mercy once in a while.
Top 8 Strategies for the ACT Science Test
Read through the instructions carefully, to orient yourself
Don't worry about details on your initial read-through
Always refer to the passage and the question-stem before selecting an answer
In order to read most graphs and tables, you have to do four things: determine what's being represented, determine what the axes represent, take note of units of measurement, and look for trends in the data
When reading data, you should be on the lookout for the three characteristic patterns or trends: extremes (maximums and minimums), critical points (or points of change), and direct or inverse variation (or proportionality)
If time is a problem, focus on the questions that require analyzing data from just a single table or graph
Don't waste time trying to figure out which scientist is "right." Just worry about understanding their different viewpoints
Don't panic if you don't understand both scientists' positions. Many questions will hinge on just one of the arguments.
