ACT Science Section PDF Guide

If you’re taking the ACT, then you’re going to encounter the ACT Science section. The ACT Science section tests your ability to think like a scientist – interpreting data, understanding experimental investigation, evaluating models and making inferences – much more than your knowledge of facts, but there are still a few basic concepts they expect you to know.

These concepts you’re expected to know are science literacy. You probably learned it all in school over the years, so don’t stress about needing to learn a ton of new concepts. If anything, you may just need a little refresher to jog your memory.

Luckily, we’ve done all the hard work and put together a simple, no-frills ACT Science section PDF guide. We’ve broken it down into four* basic categories:

  1. Elements of Experiments
  2. Biology
  3. Chemistry
  4. Physics

*Earth/Space science is also included in the ACT; however, for our purposes here it is grouped into the above four categories.

Use this guide as an outline – if you encounter concepts and terms you are unfamiliar with, do some research and fill in the blanks! Remember, if you’re curious, you end up studying for more than just the test, but also your future academic and life pursuits.
