7th Grade Essential Vocabulary



7th Grade Essential Vocabulary

Purpose: Knowing what words mean is essential to understanding every concept in science. Go through this list and highlight words you are unsure of. You can put a check next to the words you are confident with. Spend your time reviewing the words you are less confident with (highlighted words) before reviewing words with a check. Feel free to get creative when reviewing terms. Flash cards are handy, but do what works best for you.
