7th Grade Vocabulary

Vocabulary will be posted as we introduce each new chapter.  All words must be defined and creatively written with pictures in their science interactive notebook or on flashcards and glued in notebook.  If you draw a picture or write an example for each word this will help you remember them and also help you apply your words.  These words will be tested.
