Reflection: Developing a Conceptual Understanding Periodic Table Trends - Section 2: Explore


For this lesson I have found that it is important to help students begin to understand the trends through analyzing data. 

Over the years I have found that a lot of my students struggle with learning the trends of the periodic table.  However, through doing a modified inquiry activity where they are given data to graph and analyze students have the chance to figure out the trends for themselves.  This in turn helps to reinforce the trends and helps students to develop a deeper understanding of the trends for themselves. 

Then, after this activity when students begin to understand the trends, I go into the rationale behind the trends with notes.  During the notes I continuously refer back to the data from the introduction activity and use videos to help students visualize the trends.

Periodic Table Trends

Unit 3: Unit 3: Bonding & Periodic Table Trends
Lesson 9 of 9

Objective: Students will be able to explain the trends for electronegativity, ionization energy, and atomic size on the Periodic Table by performing an activity, taking notes, and doing practice questions.

Big Idea: Ionization energy, electronegativity, and atomic size display characteristic trends on the Periodic Table.
