Remember that the vocabulary on ALL tests and quizzes is always matching. You will never be asked to write a definition from memory. Below are listed the definitions of the vocabulary words from Chapter 1 of Unit D, starting with Lesson 1. Read the definition and see if you can remember the vocabulary word that it defines. Then take your mouse arrow and place it over the definition (don't click on it). You should then see the vocabulary word. This is the shortest science test that you'll take all year. It's a great way to end science!
