Unit #1: What’s a MATTER?

Match This Matter - Mass - Weight - Does not change based on location Used to measure the amount of “stuff” an object has Changes on location Anything that has “mass” or “stuff” and takes up space The measure of the force of gravity The amount of “stuff” or “Matter” in an object Match This Matter - Mass - Weight -

Matter Mass Weight Anything that has “stuff” and takes up space The amount of “stuff” or “Matter” in an object Does NOT change based on location Weight The measure of the force of gravity Changes based on location – Gravity Changes Used to measure the amount of “stuff” an object has

Phase Changes Solid → liquid Liquid → gas Gas → Liquid Liquid → solid Solid → gas Melting Evaporation/vaporization Condensation Freezing sublimation endothermic exothermic

Unit #1: Introduction to Matter States of Matter and Phase Changes Draw Three (3) Boxes equally spaced across your paper like so:

Unit #1: Introduction to Matter States of Matter and Phase Changes Label the Left Box as "Solid", the Middle Box as "Liquid", and the Right Box as "Gas"      SOLID                           LIQUID                           GAS

Unit #1 States of Matter and Phase Changes Draw what the particles would look like inside each of the three different States of Matter.     SOLID                           LIQUID                           GAS It's good as it is

Unit #1 States of Matter and Phase Changes Identify whether each state of matter has a Definite Shape or No Definite Shape.     SOLID                           LIQUID                           GAS It's good as it is Definite Shape No Definite Shape No Definite Shape

Unit #1 States of Matter and Phase Changes Identify the "amount" of Kinetic Energy (KE) that each state of matter exhibits.     SOLID                           LIQUID                           GAS It's good as it is Definite Shape Low KE No Definite Shape Medium KE No Definite Shape High KE

Unit #1 States of Matter and Phase Changes Identify the names of the different Phase Changes. Sublimation     SOLID                           LIQUID                           GAS Evaporation Melting It's good as it is Freezing Condensation Deposition/ De-sublimation
