We began class today by reciting the first 36 elements of the periodic table and allowing students to take the oral quiz, if desired. We went over section 3-4 notes on atomic number and mass number, and students worked on Activity 3-14 in their groups. After going over this page, I discussed what "isotopes" are, and we watched the BrainPop.com video on the same topic. Students then worked in their groups to complete worksheets 3-15.
No homework was assigned, and the Chapter 3 test is one week from today. Parents were sent an email today notifying them of the test.
