Learnist: ACT Science and Data Representation

The Data Representation format on the ACT Science Test will ask you to understand and interpret information presented to you in graphs or tables. Occasionally there will also be charts, scatterplots, and diagrams.

As the video below outlines, it’s important to REALLY analyze all the data you’re given. The point of Data Rep is to determine your ability to pinpoint and extract conclusions from a series of data. 38% of the ACT Science passages will be in this format.

Making sure you have a strong understanding of the data will save you lots of headache when you read the questions. The questions will be so much easier if you spend just a few minutes focusing on the data. Check out tutor Jim Jacobson’s strategy for just how to do that in this video!

Need to see a passage in action? Sparknotes reviews some basic strategy, then shows you a passage exactly like one you’ll see on Test Day. Start with the intro, then when you get to the chart, you should glance over it to make sure that you know what’s being measured and that, in general, you feel comfortable finding information in the chart.

Learnist: Biology on the ACT Science Test

Passages dealing with Biology on the ACT Science Test may feature some of these concepts: body systems, cellular biology, photosynthesis, ecosystems, evolution, and genetics. Everything you need to know about them is in the passage!

This video covers the basics of Biology on the ACT — the topics are wide-ranging as you can see in the video. Stop the video before it begins talking about Physical Sciences. You can check out the ACT Science: Physical Sciences Learn Board to focus more on that later on!
Scientists have acquired biological knowledge through processes known as scientific methods. You will see that the experiments described in the Biology passages tend to follow these 6 steps:

  • observation
  • hypothesis
  • experimentation
  • analysis
  • conclusion
  • theory/law

Looking for even more Biology brush-up so you feel more confident with the subject matter of the passages? These online Biology video lessons help students understand Biology concepts so that they can improve test and quiz scores and more easily complete homework for your high school science class! Basically every possible ACT Biology subject is covered here!
