Daily Directions • Pick up the WHITE Physical Science (1) Standards from the front counter • You will need: o Tape o Highlighter o Scissors o Red, Yellow, Green, & Blue colored pencils • Add the definition to your “MAGIC W”: Molecule: A stable unit of two or more atoms held together by chemical bonds. 44 Physical Science Vocabulary ATOM MIXTURE ELEMENT SOLUTION MOLECULE CRYSTAL COMPOUND PERIODIC TABLE 44 Physical Science Vocabulary ATOM A basic unit of matter consisting of a dense central nucleus surrounded by a cloud of negatively charged electrons. (DEFINITION) MIXTURE (EXAMPLE/PICTURE) ELEMENT A pure chemical substance composed of all atoms that have the same number of protons. SOLUTION MOLECULE A stable unit of two or more atoms held together by chemical bonds. CRYSTAL COMPOUND PERIODIC TABLE Physical Science (1) Standards 43 You are working on: Read and “code” the Physical Science Standards and DCI’s: • Highlight important vocabulary o Start with the Standards & DCI’s {Disciplinary Core Ideas} – IN BOLD • Use colored pencil to carefully underline words and ideas in the standards (and DCI’s) based on you current knowledge o RED – STOP! I need to learn this. o YELLOW – SLOW! I know a little, but I need to learn more. o GREEN – GO! I totally know this If you finish: • Practice Physical Science (PS/Chemistry) Vocabulary on QUIZLET (link on class website) Physical Science (1) Standards 43 48 Atomic Structure Electron (-) Nucleus Proton (+) Neutron Chemical Symbol Name Atomic Number Atomic Symbol Atomic Mass States of Matter <Picture of solid> <Picture of plasma> GAS LIQUID SOLID <Picture of liquid> PLASMA <Picture of gas> 49
