Curated OER
Atomic Structure and Ionic Bonding (A Visual Approach)
Using toothpicks, marshmallows, and round colored sticky dots, physical science enthusiasts build models of an atomic nucleus. In this eighth grade chemistry lesson plan, they play an atom-naming game with the models that they have...

Represent Bonding with Lewis Dot Diagrams
Lewis dot diagrams, Lewis dot structures, and electron dot diagrams are all the same thing. Young scientists learn how to draw Lewis dot diagrams and come to understand how dots and dashes represent valence electrons and ionic or...
Curated OER
Chemical Bonding
In this chemical compounds worksheet, students review the different types of bonding, define the octet rule, and draw Lewis structures (electron-dot diagrams) for given compounds. This worksheet has 7 fill in the blank, 5 short answer...
Curated OER
Oh - The Bonds of Matter!
Eighth graders identify the types of bonds elements form. In this chemistry instructional activity, 8th graders represent valence electrons with dot structures. They draw and label different atoms.

Doing Lewis Dot Diagrams
Young scholars observe the periodic table and draw the Lewis Dot Diagram. For this investigative lesson students construct information on several elements including the Lewis Dot Formation and take a quiz on the information they...

Middle School Chemistry: Chapter 4: The Periodic Table and Bonding
Six middle school chemistry lessons about the periodic table and bonding complete with handouts and animations.
Utah Education Network
Uen: Grouping Bonds
Students will group a selection of electron dot structures and determine similarities and differences between covalent and ionic bonding.
Science Education Resource Center at Carleton College
Serc: Valence Electrons and Trends in the Periodic Table
This instructor led activity will produce a partially filled periodic table that contains electron-dot models for the first twenty elements in the appropriate boxes. It will be used as a visual tool for students to connect concepts such...

Middle School Chemistry: Represent Bonding With Lewis Dot Diagrams
Students draw and interpret Lewis dot diagrams for individual atoms and both covalent and ionic compounds.
Science Education Resource Center at Carleton College
Serc: Loopy Lewis Dot Diagrams
Young scholars will use colored fruit loops to organize valence electrons to develop and master the basics of Lewis Dot diagrams. They will develop processing and critical thinking skills and also master a model of bonding.
