Welcome to the ELE - (Electronic Learning  Environment) for Physical Science grade 9. This warm up is an introduction to study the structure of atoms and what type of equipment is used to research their composition and interactions. You will additional information, tests, lecture notes, and quizzes on Mitchell's Cosmic Adventure, science website.
   I hope you earn a high grade.  Thank you!
