A “variable” in math is a placeholder for an unknown. In ACT Science, this takes on a slightly different meaning and is used to describe the factors in an experiment. Independent variables are factors that are controlled by the scientists. Did the scientists increase the heat in the experiment? Did they add or remove pressure? […]

The ACT Math Test loves triangles! Out of all the ACT math topics tested, the triangle is the most commonly tested Geometric shape. The Pythagorean Theorem and the properties of right triangles are especially tested. The Pythagorean Theorem is a formula used to find the third side of a right triangle if you know the […]

One type of ACT Science passage, Research Summaries, will present descriptions of one or more related experiments and will require you to answer questions about one or both experiments. To compare them accurately, answer the following questions as you read: How is each experiment set up? Make sure you understand the method for each experiment. […]

Scientific Notation is not a heavily-tested concept on the ACT. However, it may be combined with other topics for medium and hard-level questions. Use this guide to bolster your online studies and gain confidence for test day! Large numbers and very small decimals are often expressed with exponents using scientific notation. Scientific notation involves writing […]

Trig is definitely the most intimidating math to most ACT students – that’s because most of them haven’t seen it before (or if they have, usually only in a cursory way). The good news: if you can memorize 1 acronym, 2 formulas, and 1 definition, you’ll be all set to tackle even the hardest problems! […]

The ACT Science Test will always be the fourth test you’ll take. It will have 7 passages and you’ll have 35 minutes to complete them. That’s about 5 minutes per passage so moving confidently through this test is essential! It takes practice to gain confidence in interpreting data and understanding the meaning of unfamiliar vocabulary. […]

In a previous post, we took a look at two different types of “averages” you might see on the ACT Math Test, one of which was a fairly rare challenging concept known as “average speed. Often found in complex word problems, this type of question is one many students are less familiar with so don’t […]

Taking a few full-length ACT practice tests is essential before your actual Test Day – the ACT is a long exam, and you’ll want to build up your stamina and confidence in the months before you sit the actual test! Here are ten ways you can get the most out of your practice tests! Listen […]

Some ACT Science questions ask about the hypotheses each experiment is based on – some will ask you to weaken and some will ask you to strengthen these hypotheses. For the weaken questions, you must fully understand the set-up behind the experiments in order to know whether the results will weaken a conclusion. Try a […]

The good news is that while you do NOT have to be an excellent science student to score highly on the ACT Science test, some knowledge of the concepts tested and a familiarity with the presentation of certain concepts will almost certainly lead to better scores! 🙂 Passages dealing with Biology may involve body systems, […]
