Students completed the "Atomic Structure" PowerPoint Notes by covering nuclear reactions and the three major types of radioactive particles.  They received a "Nuclear Reaction" WS (50 pt) to complete for homework as well as the Atomic Structure Word Search (42 pt).  They will have the Atomic Structure Voc Test tomorrow and Chapter Test on Friday

Key concepts covered today on the PowerPoint include isotopes, atomic number, mass number, atomic mass, nuclear reactions, and nuclear radiation.  They received the following item for homework; "Isotopes" WS (50 pt).  They will have the Atomic Structure Vocabulary Test on Thursday and Chapter Test on Friday.

Students continued taking notes on "Atomic Structure" from the PowerPoint.  We went over today's model of the atom, contributions of James Chadwick and how the mass of atoms varies. We compared atomic number and mass number, groups and periods.  We also mentioned how to read each square on the Periodic Table.  Students got a "Determining Parts of an Atom" WS (45 pt). Students were made aware of the Vocabulary Test on Thursday and Chapter Test on Wednesday.

Students continued taking notes on "Atomic Structure" learning about the contributions of the scientists J J Thomson, Robert Millikan and Earnest Rutherford in the theory of the atom.

Students copied the objectives for the current chapter and began to take notes from the PowerPoint on "The Structure of the Atom".  We learned the contributions of Democritus, Aristotle and John Dalton in the Atomic Theory.

Students completed the "Atoms: the Building Blocks of Matter" RQ (60 pt) in class.  We copied the objectives from the PowerPoint the last 5 min. of class.

Students completed the "Atoms-Building Blocks" Review Questions (60 pt) in class.

After returning the Matter; P & C Vocabulary Test and reviewing the major mistakes, students took the Matter P & C Chapter Test (100 pt).  After completing the Chapter Test, they began the Atomic Structure Vocabulary (78 pt) which they completed for homework.

Students took the final notes on Matter & Change from the PowerPoint.  We then performed practice problems on determining % by Mass of the elements in a compound.  Then, the students completed the worksheet, "% by Mass" (60 pt) for homework.  They turned in the Matter; P & C Crossword Puzzle (44 pt) for homework.  They will have the Matter P & C Voc. Test tomorrow and Chapter Test on Thursday.

Students completed the notes from the PowerPoint on types of pure substances (elements & compounds), how to locate elements, the differences in groups/periods on the Periodic Table and how to differentiated between elements/compounds.  We will be using calculators tomorrow to calculated % by mass of elements in a compounds.  They will have the Matter Properties and Change Voc. Test on Wednesday and Chapter Test on Thursday.
