7th Grade Vocab Word List Week 8: The Roots –Bio- and –VitThe English language is filled with words that have something to do with life. The roots –bio- and –vit- both
come from words meaning “life.” The root –bio- comes from the Greek word bios, and the root –vit- comes from the
Latin word vita. The words biology and vitamin are derived from these roots. Biology is the study of living things, and
vitamins are organic compounds necessary for maintaining normal life functions. In this lesson, you will learn other
words that are related to life.

7th Grade Vocab Assignment Week 8
Hello Nativity seventh graders! My name is Dr. Abraham Erskine, and I am the German scientist who invented the super
soldier serum that turned Steve Rogers into Captain America. I’m afraid that I have run out of ideas; I need your help to
get my research back up and running. I would like you to submit a proposal for an experimental medical procedure. No
idea is too crazy. In your proposal, use five of this week’s words. Write at least 5 unique, complete sentences – one
sentence per vocab word you choose – using the word correctly (part of speech and definition). Always use the words
from the far left column – NEVER THE “RELATED” WORDS. Sentences should be more than just the word and the
definition. Sentences should be unique (different from every other sentence on the page, written by you and you
alone). Sentences should be written neatly. The paper should have a heading and should be neat (no folds, tears, etc.).
Underline the vocab words (or circle, highlight, etc. – just call my attention to the word). Skip a line after every line
you’ve written (think of it as double-spacing the whole page). This is in paragraph form.
