Unit 1 INTRODUCTION TO MATTER 1.2 What is particle diagram? AIM: How do you create a particle diagram and how do you use it to distinguish between a pure substance and a mixture? DO NOW: How is matter classified? Fill out the graphic organizer using notes from yesterday. MATTER MIXTURE PURE SUBSTANCE HETEROGENOUS MIXTURE HOMOGENEOUS MIXTURE COMPOUND ELEMENT

WHAT IS A PARTICLE DIAGRAM? A diagram serves as a representation of something Examples of diagrams: Diagram of this classroom Diagram of a plant Diagram of

WHAT IS A PARTICLE DIAGRAM? A drawing that represents atoms or molecules These diagrams can represent elements and compounds, and their molecular composition (depending on how they are arranged in the diagram).

LEGEND Serves as a key. It helps us identify what each part of the diagram represents KEY

GROUP ACTIVITY With a partner: Classify the following items as a homogeneous mixture, heterogeneous mixture, element or compound. Draw particle diagrams representing each of the items. (10 mins) With your table: Create a particle diagram for the category listed on the post-it. (5 mins)

ITEMCLASSIFICATIONPARTICLE DIAGRAM (include a key) A Silver Ring Oil and Water Aluminum and Iron Water Oxygen
