In preparation for the Flame Lab tomorrow, students received the handout for the lab and were given the first 15 minutes of class to read the lab and begin working through the pre-lab questions (due tomorrow).  After, we worked through the Lesson 18 PowerPoint and then students partnered up to complete the Lesson 18 Worksheet and the Table of Valence and Core Electrons..  For homework, students should work through questions #1-10 at the end of Lesson 18 in the textbook in addition to completing the Flame Test pre-lab questions.
