Properties of the Elements

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 began the lesson with a PowerPoint that included the definition of reactivity (along with the video below), then worked through the Lesson 9 Worksheet by organizing elements via a card sort activity.  For homework, students should complete Lesson 9 textbook questions 1, 2, and 4.  Students must also complete the Penny Lab prelab questions (#1-8) in order to participate in the lab tomorrow.  As a reminder, students must also turn in a signed syllabus and safety contract to participate in the lab.
