The Science Test is the fourth section on the ACT. You have 35 minutes to answer 40 multiple choice questions. While this section requires you to have a general understanding of science, you should be able to answer almost all of the questions through the interpretation of various passages, graphs, and charts, rather than having to draw from any particular scientific facts.
The Science Test consists of seven different groups of questions, each of which is based on a different passage or chart. Each group of questions contains 5 to 6 questions, which get increasingly harder in difficulty. These questions will require basic comprehension of passages and charts, as well as the ability to analyze and interpret these passages and charts and see general patterns in the data.
The ACT categorizes each passage on the Science test into one of three categories, each of which encompass a different approximate percentage of the test:
We break these subsections down even further to focus on the specific skills necessary to be successful on the ACT Science section.
Let’s go through an ACT Science passage using the above approach.
Briefly looking over the passage, we can see that this passage involves circuits. One graph shows current (A), voltage (V), and time, while the second graph shows different types of voltages and time.
Now we should immediately go to the questions.
According to Figure 2, the maximum positive value of Vs was approximately:
a) 125 V.
b) 200 V.
c) 250 V.
d) 275 V.
This question leads us to Figure 2, where we are looking for information about , which is the dashed line.
We can see that the maximum positive value of occurs where the time equals 8 msec. The amount of voltage at that point is around 250 V, so the answer is C.
Notice that we didn’t have to understand any science to answer this question, we simply had to make sure we were reading the right figure, graph, and unit.
