Next, students received copies of progress reports and work from Chapter 1.  Until students gain access to Synergy, progress reports will be provided after each chapter quiz.

 

For our work today, we began our exploration of the Periodic Table by constructing our own.  In Lesson 9, students walk the path of the famous Russian chemist Dmitri Mendeleev who assembled the first predictive periodic table using the chemical and physical properties of the 63 elements known back in the 1860s.  We ended class yesterday with a video showing the reactivity of alkali metals upon contact with water:

For our work today, we reviewed the Lesson 9 PowerPoint, then worked through the Lesson 9 Worksheet by organizing elements via a card sort activity.

The remainder of class time was available to read Lesson 9 in the textbook and answer the Lesson 9 questions in the Chapter 2 Study Guide.
