ACT® Science Vocabulary Words

ACT® Science is all nearly getting the maximum number of questions right in a relatively brusk period. Having a strong vocabulary helps a lot in improving your understanding of the questions and reducing the time it would take for you to understand the question. This article volition aid you ameliorate your Deed® score by compiling a listing of commonly used words in the ACT® Science vocabulary forth with their meanings.

Remember that this word list is not a substitute for the concepts themselves. Information technology serves as a summary of normally used words with which you need to be familiar. However, if you do non understand a discussion or the associated concept, it is necessary that you study that concept from a recommended textbook.

A Few Tips to Help You Remember the Words and Concepts

Some students understandably have a hard fourth dimension memorizing a given listing of words or phrases. Here are a few tips which might aid you if you experience like you lot're getting stuck and are unable to remember the words or concepts:

• Use flashcards as a tool for improving your learning.
• Do non attempt to report and remember all of them at once. ACT® Science vocabulary is not something you can read once and then remember. Break them downwardly into sets of 10 – 20 words and then report them. Once you lot feel confident with one set, motion onto the side by side set until you are done.
• If you are unable to understand the underlying concept, endeavour looking it upwardly in your textbook or online. It is e'er easier to call back something you understand rather than merely memorizing it.
• You lot can too use the listing every bit a tool for a quick review earlier your Deed® test.
